Customer Guide Of Complete Pellet Plant For Sale
How does a pellet plant work?
How does a pellet plant work? What everyone needs to know is that the pellet making process, pellet plant operation mode, and post-maintenance methods of the feed pellet plant, biomass pellet plant, and organic fertilizer pellet plant are all different, not to mention other pelleting plants such as tire fiber pellet production plant, rubber pelletizing plant, cat litter pellet making plant. In addition, because the equipment configuration of different pellet production lines is also very different, their operation conditions are also different, so let's take a 20 ton per hour heavy duty wood pellet plant project we have done as an example to tell you how a large wood pellet factory works.
20TPH turn-key biomass pellet plant process flow:
After peeling the trunk of the log, enter the slicer and cut into small wood chips. The size of the wood chips is 20-30mm and the thickness is about 5-10mm. Then the wood is coarsely powdered by the grinder, and then the water content of 40% is removed by the three-layer tumble dryer. The raw material is dried to about 15%, and then finely powdered to 3-4mm sawdust with a wood pulverizer, and finally granulated. The diameter of the processed finished product is 6-10mm optional. After the granulation is cooled, it is packed by a small bag packaging scale. Into 20-50kg/bag. Convenient to transport and sell. This project is a 17.5-22.5 tons of raw wood pellet production line per hour. The total equipment power is about 5,027kw. The workshop covers an area of 10,000 square meters, including a raw material warehouse and a finished product warehouse. The entire pellet line is compact in design, reasonable in structure, and meets environmental protection requirements. And can carry out directional design according to customer requirements. (The applicable raw materials for this project mainly include logs of various trees such as pine, fir, albizia, zelkova, eucalyptus, and oak.)

- Since the client of this project requires all finished pellets to be distributed in bulk, various types of packaging equipment can be adjusted according to the client's requirements for finished product packaging.
How to set a chicken feed pellet manufacturing plant? Since our pellet plants are all customized, there is no exactly the same pellet manufacturing plant for RICHI. Let's take a 10 tons per hour chicken feed pellet plant as an example to tell you how to build a pellet factory. If you want to process biomass pellets, cat litter pellets, organic fertilizer pellets, rubber tire pellets, and plastic pellets, the configuration of the pellet factory is different, so please consult online for more details.
10T/H poultry feed pellet processing plant production process:
Poultry feed is characterized by moderate crushing fineness (sieve aperture 2-4mm), moderate maturation and conditioning requirements (poultry feed making machine for pellets mostly use double-layer conditioners), and the finished particles have a large diameter (particle diameter is about 2.5-4mm).

According to the needs of different customers, the 5t/h straw pellet plant solution can be optimized for configuration:
- If required, buffer bins can be added between each section to replace the storage yard. The advantage is that it can increase the degree of automation of the production line and reduce the dust pollution in the workshop; the disadvantage is that it will increase the construction cost of the production line and is caused by crushing. The bulk density of the rear material is very light, and it is easy to form arches in the warehouse.
- If the moisture content of the raw material is not higher than 15%, it is not necessary to use a dryer and granulate directly after crushing; if it is higher than 15% but lower than 20%, consider using dry and wet materials to mix After the moisture is neutralized and reduced, granulation is carried out;
- The packaging equipment can be adjusted according to the customer's requirements for finished product packaging. It can also be stored in bulk or steel silo.
