How to choose fertilizer manufacturing machine?

1. How to choose fertilizer manufacturing machine?

How to choose the fertilizer manufacturing machine for the organic fertilizer production line? The organic fertilizer production line mainly includes organic fertilizer making machines such as mixers, organic fertilizer pellet making machine, etc.

  • First of all, customers should first look at the scale of fertilizer manufacturing machine and organic fertilizer production line manufacturers with the naked eye. Only a regular large company can make organic fertilizer equipment that satisfies customers. After all, the cost of making these equipment is relatively high.​​
  • Secondly, it depends on whether the fertilizer manufacturing machine manufacturer has a professional design and production team and advanced production process. Only professional technicians can perfect the function of the product and keep the error control very low.

Then it is the production process of the fertilizer manufacturing machine you purchased in the future. If there is any problem, the professional after-sales team can also help you solve it as soon as possible. Richi Machinery has strong technical force and high-quality workforce, as well as CAD design research and development center, a complete after-sales service system.​​

  • Thirdly, fertilizer manufacturing machine price has always been a factor that customers care about. Many customers may choose some informal organic fertilizer production line manufacturers or small fertilizer manufacturing machine manufacturers because the prices of organic fertilizer production lines of large manufacturers are too high, but the quality and after-sales of these small manufacturers are often the same, when the customer buys the product there will be one problem or another.

At present, Richi Machinery has successfully launched a 1-200,000-ton organic fertilizer production line and a complete set of fertilizer manufacturing machine for organic fertilizer and compound fertilizer, which can be adapted to various types of production.​​

  • Finally, the after-sales service of the organic fertilizer production line is a link that customers pay great attention to. Whether a fertilizer manufacturing machine manufacturer can achieve real worry-free after-sales, customers will find out when purchasing products and on-site inspections of manufacturers.

After purchasing products from a high-quality fertilizer manufacturing machine manufacturer, the after-sales service and technical team of the manufacturer will make a return visit for a fixed period of time, and then they will also analyze and deal with various problems encountered by customers in the fastest time, and seek the maximum satisfaction of customers to improve the comprehensive competitiveness of fertilizer manufacturing machine manufacturers.

2. Common large fertilizer production line process

Common large-scale organic fertilizer production line processes include: pig manure organic fertilizer production line, chicken manure organic fertilizer production line and cow dung organic fertilizer production line, etc. Compared with small-scale fertilizer manufacturing machine production lines, large-scale ones must meet the characteristics of storage, transportation, and organic fertilizer preservation.

Therefore, the large-scale fertilizer manufacturing machine production line chooses the process of granular organic fertilizer production line to process pig manure, cow manure, and chicken manure into nutrient-rich organic fertilizer, which is a good way to achieve more benefits for enterprises and form a good way of recycling and recycling resources for environmental protection and benign development!

For the process of large-scale organic fertilizer production line, in addition to meeting the small-scale composting process and crushing process. The following fertilizer manufacturing machine processes are also required:

  • Granulation process: The choice of granulation method is very important in the production of organic fertilizer. Production of various types and specifications of organic fertilizer pellet making machine, disc fertilizer pellet mill machine, organic fertilizer stirring teeth organic fertilizer pellet making machine, new-type stirring teeth turning organic fertilizer pellet making machines.

The advantage of the fertilizer pellet making machine is that the granulation particles are uniform, With stable performance and long service life, it can produce both organic fertilizer and inorganic fertilizer and organic-inorganic compound fertilizer. This process chooses a disc fertilizer manufacturing machine.​

  • Drying and cooling process: Although most of the granulated materials have been formed into granules, the moisture and strength of the granules are not up to the standard, so they must be dried.

The rotary dryer is a rotary cylinder with a lifting plate inside. Under the action of the plate, the material is fully lifted to exchange heat with the hot air generated by the hot blast furnace, and the temperature of the material is increased.

The moisture will rapidly diffuse outward due to the pressure difference between the temperature and the partial pressure of the steam, and the diffused moisture will be taken away by the wind, so as to achieve the effect of drying the material and improving the strength.​

  • The dried material is conveyed to the cooler through the belt. The rotary cooler is also a rotary cylinder with a lifting plate. Under the action of the plate, the granulated material is lifted up and sucked into the cylinder with cold air perform heat exchange and cool to near normal temperature to further increase particle strength and reduce moisture.​​
  • Sifting process: There are powdery materials in the cooled material, and the fine powder and large particles are all screened out by a screening machine. After the particles are crushed, they are returned to the mixer through the same return belt conveyor with the fine powder. In this way, a complete fertilizer manufacturing machine production cycle is formed, and the quasi-finished products enter the coating process.​​
  • Coating packaging process: Qualified finished products are packaged by manual weighing on scales or automatic packaging machines.​​

The use of large-scale organic fertilizer production line and technology can create great benefits from existing resources through fertilizer manufacturing machine.

Processing animal manure into organic fertilizer is not only energy-saving and environmentally friendly, but also doubles the value of original chicken manure, which can completely make up for your limited investment. The chicken manure fertilizer manufacturing machine project has a short construction period, low risk, and short payback period. Generally, the investment of fertilizer manufacturing machine is recovered within one year and the profit is generated that year!

Advantages of floating fish feed pellet machine

1.Characteristics of aquatic feed

There are also multiple configurations. Floating fish feed pellet machine can process various aquatic feeds, such as ornamental fish feed, aquaculture fish feed, etc. According to the nature of fish feed products, it is divided into sinking fish feed and floating fish feed; it is an ideal equipment selection for the aquaculture industry.

Floating fish feed making machine does not require boilers, occupies a small area, and is easy to operate. It is a step-type fish feed production line with different yields, price, the daily output is 1-5 tons, which meets the production demand of 0-30,000 acre of aquaculture feed.

When choosing floating fish feed making machine, we must first understand the many characteristics of aquatic feed:

  • Small pellet size. Due to the short digestive tract of aquatic animals and related physiological characteristics, in order to speed up digestion and absorption, fish feed should be crushed with a smaller pellet size than livestock and poultry feed.
  • High in protein and low in carbohydrates. The protein content of livestock and poultry feeds is generally less than 20%, while the protein content of aquatic animal feeds is mostly 30% to 40%, and the protein content of turtle and eel feeds is as high as 65% to 70%.
  • The pellet feed made by floating fish feed pellet machine has a compact structure, high cohesiveness and water resistance. For shrimp feed, the stability of the pellet feed in water for more than 2 hours is required to produce high-quality aquatic feed. Only the use of extruded fish feed can achieve water stability sexual effect.
  • It must rely on scientific and reasonable processing technology and combine it with advanced, reliable and stable floating fish feed pellet machine. In this regard, the choice of floating fish feed pellet machine is particularly critical.

1.Why use floating fish feed pellet machine?

With the development of aquaculture in the direction of scale, intensification and specialization, its requirements for aquaculture feeds are getting higher and higher. Traditional powder compound feeds, granular compound feeds and other types of compound feeds all exist the disadvantages of poor water stability, fast sedimentation, easy to cause feed loss and water pollution, etc., have become more and more unsuitable for the development of modern aquaculture.

And extruded fish feed made by floating fish feed pellet machine solves these disadvantages, more and more aquaculture farmers and floating fish feed mill installs floating fish feed extruder machine. Wet process twin-screw floating fish feed pellet machine, the output can reach 1800-2500kg/h in one hour.

The dry process does not require a boiler. The wet process of floating fish feed pellet machine requires a boiler, with high output and uniform aging, which can be selected according to customer requirements.

3. What is extruded feed?

Extruded feed is a new technology of feed processing. It is a process of processing into feed through extrusion to generate high temperature and high pressure.

1.First, floating fish feed pellet machine was developed in the 1930s for the production of pasta. It was later modified to produce animal feed and human food such as snacks, candy.

Due to its high flexibility, the extrusion process can produce foods of varying degrees of fat, density, shape and size, and it can also produce a wide variety of feeds, including floating, semi-floating, and sinking feeds.

Extrusion technology of floating fish feed pellet machine has been used to produce shrimp feed since the early 1970s, but it has not been widely used because it swells after extrusion, causing the feed to float on the water for long periods of time.

In order to reduce the buoyancy of the feed, fish feed manufacturers must reduce the starch content, which leads to increased raw material costs. But with the continuous development of floating fish feed pellet machine extrusion technology. 

These shortcomings have been greatly improved, such as adjusting the design and speed of the screw, changing the configuration of the mold and the components of the vacuum heat sink. At present, it is possible to produce extruded feed for shrimp with a density equal to that of pelleted feed.

Extruded feed made by floating fish feed pellet machine can reduce the cost of raw materials to a certain extent. First, a lot of wheat starch can be replaced with cheaper starch.

2.Secondly, due to the humidity, temperature and high pressure of the floating fish feed pellet machine, easily digestible substances can be produced, which facilitates the digestion and absorption process.

After the extruded feed is expanded, it can produce a substance that improves appetite. This creates the potential to produce a more attractive shrimp feed without relying on expensive protein. Due to the continuous progress of extrusion technology, the cost of producing extruded feed is expected to be further reduced.

At the same time, the advantages of extruded feed in sterilization are unmatched by pellet feed. As a result, floating fish feed pellet machine are expected to become increasingly popular.

Take straw pellet production as an example. After the straw is processed by the biomass fuel pellet machine, it will become straw fuel pellets. We all know that the proportion of straw in our country is very large, and our disposal of straw is usually either burning or throwing away, because straw is really useless.

Founded in 1995, Richi Machinery has been developing steadily and steadily in the field of pellet processing and biomass pellet mill for sale. It is mainly engaged in the R&D and manufacturing of equipment required for industry projects such as feed, biomass energy, and organic fertilizer. It has gradually formed a complete R&D, production, sales and service system, provide technical solutions and supporting products.

(1)Why buy a biomass pellet mill to process straw into fuel?

The price of a fuel pellet machine is not three or two yuan. Is it cost-effective to process almost worthless straw? The biomass pellet mill manufacturer can clearly tell you that it is worth it! Excellent value.

Why do I say that? We should not be unfamiliar with coal. Coal is the main fuel we use. However, the formation time of coal is too long, which means that if there is no solution, coal resources will be exhausted.

The burning of coal will release polluting gases that are harmful to the air, which also means that if we want to have a good living environment, we must find a resource that can replace coal. Fuel pellets are a new type of fuel that replaces coal, and straw fuel is one of the biomass fuel pellets.

(2)Biomass pellet mill processes straw into fuel

After the straw is processed by the biomass fuel pellet machine, it will become straw fuel pellets.

(3)What is the use of straw after being made into fuel?

After the straw is made into fuel pellets by biomass pellet mill, it is used as fuel to burn completely, and it does not pollute the air. Another point is that our straw resources are very rich, and this is a renewable resource, so what are the comparisons between biomass fuel and coal?

(4)What about the advantage?

  • The price of biomass pellet fuel is much lower than that of coal. At present, the price of coal in the market is 150-200 yuan higher than the price of biomass fuel pellets per ton;
  • The fuel pellets made by biomass pellet mill meet the environmental protection requirements of our country and are a new type of biomass energy;
  • The biomass fuel pellets have uniform shape, small volume and high density, which is convenient for transportation and storage;
  • The biomass fuel pellets made by biomass pellet mill can be fully burned, but when the coal purity is not high, it cannot be fully burned, and there will be coal impurities. The fuel pellets burn at a rate that matches the rate at which they break down.

Biomass fuel pellets can be fully burned, but when the coal purity is not high, it cannot be fully burned, and there will be coal impurities. The fuel pellets burn at a rate that matches the rate at which they break down.

Taking straw as an example, after the straw is pressed into fuel pellets by the fuel biomass pellet mill, the combustion efficiency is increased from 20% to more than 80%; The calorific value of one ton of straw is equivalent to 1 ton of coal, and the average sulfur content of coal is about 1%; in addition, the fully burned straw ash can be returned to the field as fertilizer. Therefore, the use of fuel pellets as heating fuel has strong economic and social value.

(5)The fuel pellets have high volatilization rate, low ignition point, sustainable combustion, and are directly used in boilers.

(6)The fuel pellets produced by the biomass pellet mill do not contain harmful chemicals, the ash can be directly used for crops, and the ash is rich in organic potassium. After coal is burned, a large amount of sulfur and phosphorus compounds and coal impurities will be produced, which will pollute the land everywhere, which is not conducive to the construction of environmental protection in my country.

In the future, my country’s energy construction will take a sustainable path and promote the use of environmentally friendly new energy fuels, which will play a positive role in my country’s environmental governance. The future development of biomass pellet mill will be bright.

poultry feed pellet making machine

Formula for using poultry feed pellet making machine

Recently, I have summarized the questions of many friends and found that many people are asking about the formula of pellet feed, which is made by poultry feed pellet making machine. In fact, the raw materials and livestock and poultry used by each customer are different and cannot be generalized. Feed pellet machine formula should follow 3 principles, here are some suggestions for reference:

(1) For the customers who breed by themselves, what materials are there now?

That is to say, if you breed by yourself, you can use whatever material you used before and what material you use now. For example, you feed pigs with corn, bran, and sweet potato seedlings, then crush these three, and then use a feed pellet machine to make pellets.

(2) Pellets can be mixed with a variety of raw materials, not just one material.

In the cognition of many friends, only one material is used when using a poultry feed pellet making machine to press pellets. For example, I only use corn stover. In fact, this is not the case. You can pulverize various materials, then mix and stir, and then make granules. Pellets have always been known for their nutritious, sweet taste, so their nutrient richness is not only reflected in one aspect.

So you don’t have to think that the poultry feed pellet making machine is an artifact that is out of reach.

(3) When the pellet feed is configured, the ratio of roughage is generally 6:4.

When using a poultry feed pellet making machine to press pellets, if you have roughage in your ingredients. So we recommend you, the ratio of concentrate to roughage is 6:4. For example, you can use 60% corn, bran, 40% straw, etc. Experiments have shown that this ratio is not only conducive to the formation of particles, but also that animals eat fine and thick, especially sweet, which is conducive to livestock eating.

(4) Questions about additives.

Many friends also asked about additives. Additives are generally not required when pellets are pressed with a feed pellet machine.

Pellets have been semi-cooked during high temperature inhibition, just like people eat them. Cooked food is better than raw food. And in the granulation process, high temperature can kill many bacteria, so no additional additives are needed. Of course, it’s understandable if you want to use it. Written at the end: Different reared animals use different feed ingredients and different diets. When configuring pellet feed ingredients, it can be used flexibly and does not need to follow any principles.

The above are just some of Richi Machinery’s suggestions. In practical application, please pay attention to your actual situation.

poultry feed pellet making machine

1.How can the ring die poultry feed pellet making machine effectively prevent static electricity?

About the operation of the anti-static ring die poultry pellet machine:

(1) Before using the poultry feed pellet machine, it should be checked whether its electrostatic grounding is firm, otherwise wet grinding should not be performed.

(2) Use single grains when grinding wet powder. You need to send a bucket of wet powder from the centrifugal chamber to the grinding chamber, and then transport a bucket of water, so as to avoid concentrated accumulation of particles and avoid the concentration of acetone in the space too high.

(3) On the ring die poultry feed pellet making machine, masks, laundry gloves, anti-static underwear, and anti-static shoes can be worn.

(4) It is forbidden to collide the wet powder hammer and the stainless steel barrel with the silo of the poultry feed pellet making machine to avoid electrostatic sparks.

(5) Before grinding, check the thermometer and hygrometer beside the poultry feed pellet making machine to make sure the humidity is above 50%. If the indoor humidity is lower than 50%, it can be watered and poured before using the poultry feed pellet making machine until the indoor humidity reaches more than 50%. Otherwise, the use of poultry feed pelletizers is not allowed.

2.What is the reason why the new poultry feed pellet making machine does not feed?

The new poultry feed pellet making machine mainly uses straw raw materials to complete the granulation process. Today, poultry pellet making machines are favored by more and more users, and the number of users investing in new poultry feed machines has also increased.

However, some users’ feed pelletizers are unable to discharge. In fact, the problem that the new poultry pellet feed machine does not feed is not complicated, mainly due to the following reasons:

(1) Mold problem, the newly purchased new machine mold needs to run, so the new pellet  needs to run under the raw material with added oil (use 5 kg of feed, 1 kg of feed, 5 kg of fine sand, 2 kg of oil, or no water can be added use waste oil). (Related post: bentonite cat litter production line )

Usually the moisture of the raw material should be controlled between 4-6%. Adjust the gap between the roller and the template to about 1mm. After adjusting the roller, the fixing bolts must be tightened. (If the template hole is blocked, it needs to be opened with a hand drill before adding).

(2) Check the blade and filter. The gap between the knife edge and the filter must be suitable!

(3) The motor of the pellet  is reversed. Motors can be dangerous.

(4) Sometimes it can’t be output, and sometimes it can’t be output. Usually, this has nothing to do with forward and reverse rotation of the motor. The length of time is related to the aging degree of the pellet  template.

(5) The amount of water also has a great relationship.

(6) The compression ratio of the mold also has a great relationship. (For more: Richi Pellet Machine )
