   The video shows how the corn stalk pellet making machine works. The structure of the pelleting machine is simple. It consists of stainless steel feeder, pelletizing chamber, Siemens motor, etc.  

The working principle of the machine is: firstly, put the crushed raw materials into the feeder, the raw materials enter the pelletzing room smoothly with the push of the force feeder. Then, in the pelletizing chamber, the materials are pelletized under the pressure between the ring die and rollers and the corn stalk pellets finally extruded out from the die hole.

The machine is easy to operate and use. It can not only be used as an individual pelletizer for farmers or small biomass pellet plant but also is widely used in biomass pellet production line and feed pellet production.

As a reliable pelletizer manufacturer with nearly 30 years’ experience, RICHI Machinery specializes in providing our customers with high quality and inexpensive machines and equipment and satisfactory solutions for pellet manufacturing.

Uses of Corn Stalks

Corn is one of the most common crops, but after the corn harvest, how to deal with the residual corn stalks is often a headache. Corn stover production accounts for about the general corn crop production, if you can make good use of corn stalks, will be able to maximize the benefits for people. Below is a list of the components of corn stalks:

Component content of corn stalk

Corn stover is typically used in three ways: as feed, livestock bedding, and biomass burning.

Corn stalks as Biomass Fuel

Often people use corn stover directly as fuel to burn, it can be burned in the furnace, used for heating or to generate electricity, but this will not only cause pollution to the air, it is also extremely inconvenient to use.

Corn stalks as feed

In addition to burning as fuel, corn stover is also a good feed material, which contains more than 30% of carbohydrates, 2%-4% of protein and 0.5%-1% of fat. It can be used directly for feeding animals.

Corn stover as bedding or litter

Corn stover can also be used as livestock bedding to capture and hold bulk material for animal manure. It is also an organic material in its own right and can be left in the field as a soil conditioner for plant bedding and used to improve the soil.

Why making corn stalk into pellets?

The usable value of corn straw is very high, however, if the corn stalk is not densified, the cost of loading and unloading, storage and transportation of corn stalks will be relatively high. So now more and more people choose to process corn stover into pellets, which is the most effective way to densify corn stover.

The following are the benefits of corn stover pellets, I believe you will know why to make corn stover into pellets after understanding!

Making corn stalk into pellets
  • Corn stalks have a low weight capacity, and piling them up outdoors will not only take up valuable land resources, but may also cause pollution. However, when processing the corn stover into pellets, the density of corn stover pellets is up to 603.6kg/m³, which is small and easy to transport and store.
  • The corn stalk pellets are cleaner and more environmentally friendly than other fuels, emitting less smoke and dust when burned.
  • Corn stover is processed into corn stover feed pellets after high temperature and high pressure pressing, corn stover is fully cooked, more conducive to the digestion and absorption of animals, and increase the amount of animal food.
  • The high temperature and high pressure pressing of the pelletizing machine can kill bacteria and viruses and reduce the probability of animal diseases.
  • Corn stover can be mixed with other feedstuffs to complete the pelleting, which can provide more comprehensive and rich nutrients for animals, and at the same time can effectively prevent the phenomenon of picky eating.
  • The corn stover pellets are widely used as biomass pellet fuel, and can be used as stoves, boilers, heating stoves and similar heating systems.
  • Corn pellets are high density, highly mobile and easy to manage. It is more convenient to use whether feeding animals or as fuel

The most commonly used machine to process corn stalks into pellets is corn stalk pellet mill. Let’s learn how to make corn pellets!

How to make corn stalk pellets?

The process of making corn stover pellets depends on your production needs. If you are planning to produce large-scale straw pellets for feedstuff, we suggest you can refer to the animal feed pellet production line. If you intend to produce corn stover pellets for biomass pellet burning, we suggest you to refer to the biomass pellet production line.

How to make corn stalk pellets

Generally speaking, the production process of corn stalk pellets includes cleaning, crushing, pelletizing, cooling and baling. Therefore, the required equipments are cleaning equipment, corn stover crusher, corn stalk pellet mill, corn stover pellet cooler and packing machine. Of course, the specific equipment configuration should be adjusted according to your needs. For example, if you produce pellets for your own use or the scale of production is small, then you can choose the cooling and baling method of natural cooling and manual baling. But if your production scale is large, we still suggest you to equip professional cooling equipment and automatic baler, which can improve the production efficiency and ensure the quality of pellets.

01 Raw material cleaning

First of all, the first step is to clean the raw materials to remove impurities. Because corn stover is usually in the field, it is inevitable that it will be mixed with many impurities and return, so it is necessary to remove the impurities and dust in it through the screening equipment. This can ensure the quality of corn stover pellets at the same time can also avoid the impurities in the raw material to the subsequent crusher and granulator damage.

02 Crushing corn stalks

Corn stalks are generally too large to be placed directly into the pelletizer. The ideal size of the raw material for the granulator is about 3mm, so we need to use the crusher to crush the corn stover to 2-3mm fine powder, to achieve the conditions of the corn stover granulator for granulation, and then the subsequent pelletizing.

03 Drying corn stalks (optional)

After crushing, according to the moisture content of the raw material for drying or water treatment. Generally speaking, the moisture content of the most suitable raw material for pelletizing should be about 13-15%. If the moisture content of your raw material is too high, it is recommended to use the dryer to dry the material to about 15%.

04 Corn stalks pelletizing

Pelleting is the most critical process. Corn stalk pellet machine can press the corn stalks into molded pellets. It is crucial to choose a reliable corn stover pelletizer because it directly determines the output and quality of corn stover pellets.

We recommend that you choose a pellet maker equipped with a forced feeder and a feeder with an anti-arching bin, as such a pellet maker is fully integrated with the characteristics of corn stover and can ensure that the corn stover enters into the pelletizing chamber to complete the pelleting smoothly and steadily. There is another point you should consider, is the part of the contact with the raw material is made of stainless steel, stainless steel design of the pelletizing machine is not only good quality, smooth operation, long service life, but also to avoid corrosion of the machine on the raw material to ensure that the quality of the finished pellets.

05 Cooling corn stalks pellets

Corn stover pellets just out of the pelletizer temperature and humidity are high. And they are relatively soft and hot, very easy to deform. Direct storage will not only damage the appearance of the pellets but also cause the pellets to deteriorate. Therefore, you need to use the pellet cooling machine to cool the pellets to room temperature. It can also improve the hardness of the pellets and help to improve the preservation time of the pellets.

06 Packaging the pellets

After cooling, congratulations you have completed the pelletizing. The next step is to pack the corn stover pellets or store them directly according to your needs. The automatic packing machine is able to pack the corn stover pellets into bags of different capacities with high packing precision and fast efficiency. It is more convenient for storage and transportation after packing the pellets in bags.

Precautions for using the corn stalk pellet machine

Corn stover pelletizer is an environmentally friendly and efficient pelletizing equipment, which has the features of low maintenance rate and easy to use and operate. However, in order to ensure the molding rate of the pelletizer as well as to extend the service life of the equipment, it is recommended that you pay attention to the following precautions after purchasing the pelletizer:

  • The moisture of raw materials should be treated to about 15% before putting them into the pelletizing machine for pelletizing. If the moisture of raw materials is too high, the pellets will be loose when pressed by the granulator, but if the moisture is too low, the materials will be difficult to be pressed and molded and the molding rate will be low and the degree of pulverization will be high. Therefore, it is recommended to test the moisture content of raw materials first. If the moisture content of the material is too high, you can choose to reduce the moisture of the material by drying or drying. If the moisture content is too low, you can add water to increase the humidity of the material.
  • In addition to moisture, the size of the material will also greatly affect the granulation effect of the granulator. Before the granulator starts to granulate, it is recommended to crush the material to 2-3mm before granulation. If the size is too large, it will cause blockage of the granulator, affecting the normal operation of the machine, and the quality of the granules produced is not good.
  • Machine should be strictly refer to the instructions for use of granulator equipment before use, in strict accordance with the instructions for use of the machine to operate the machine and according to the requirements of the period of the granulator for installation, operation and maintenance!
  • Corn stover granulator workplace should be spacious, ventilated, with reliable fire prevention equipment, the workplace is strictly prohibited smoking and open fire.
  • After each start-up idling for three minutes, to be normal operation of the machine and then uniform feeding; please be sure to remove the hard debris in the raw materials, to prevent stones, metals, flammable and explosive products into the hopper, so as not to damage the machine.
  • It is strictly prohibited to take down the hopper and start the machine, in order to prevent the material from flying out and hurting people.
  • Do not put your hand into the hopper or use other tools to dial material during normal operation to avoid danger. Gradually put a little wet material on the machine before shutting down at the end of the day, so that the material can be discharged smoothly after starting the machine on the next day. If you hear any abnormal ringing during the rotation of the corn stover pelletizer, you should stop the machine immediately for inspection.
  • Pellet machine is mainly suitable for coarse fiber granulation, such as: wood chips, rice husk, cotton stalks, cottonseed hulls, weeds and other kinds of crop straw, domestic garbage, waste plastics and factory waste, low adhesion rate, difficult to form the material granulation, briquetting, rod making, but also for biological bacterial fertilizers, organic fertilizers, composite fertilizers, such as low-temperature granulation.
