The ultimate guide – learn about the biomass pellet making machine

learn about the biomass pellet machine

Biomass pellets introduction

Biomass pellet fuel is made by biomass pellet machine. It has the characteristics of environmental protection, cleanliness, high heat, and sufficient raw materials. Wide range of raw materials, including straw, corn stalks, cotton stalks, rape stalks, wheat straw, sesame stalks and other agricultural residues; and forestry wastes such as orchard pruning residues, municipal pruning residues, and garden industry residues.

The high pressure and high temperature in the granulation equipment turn these raw materials into granules, and then cut into small pieces by scrapers. The end result is a clean, environmentally friendly, recyclable high-quality biomass pellet fuel.

The final pellets are suitable for schools, enterprises and institutions, biomass boilers, heating furnaces, vaporizers, bathing, washing, printing and dyeing, textiles, food, spraying, clothing, heating enterprises and other industries.

Introduction of Biomass Pellets Production Process

Biomass pellet fuel production steps: raw material processing, drying, granulation, cooling, packaging. At the same time, each link is equipped with a strict quality control system to ensure the quality of the products.

Biomass Pellet Production Process

Chipping machine

Chippers process logs into small wood chips., and the chipped wood chips are output through the conveyor, and the output materials are stacked or transported through the conveyor to the shredder for next production.

Grinding machine

The shredded chips are transported to the grinding machine through a conveyor for pulverization. After the pulverized material reaches the standard of compressed particles, it is stacked or transported to the dryer through a conveyor for the next step of production.

Drying machine

Biomass pellets have strict requirements on the moisture content of raw materials. Usually, the moisture content should be below 15%. So, we need to use a professional and dedicated dryer, transport high-moisture raw materials to the dryer through a conveyor, and then dry them with hot air. After reaching the specified standard, the next step of production can be carried out.

Characteristics of RICHI Biomass Pellet Making Machine

  1. Lubrication: The pressure roller, main shaft, and other assemblies are all dust-free precision assembly, using high wear resistance and multi-sealing, spray-type thin oil circulation lubrication, no need to add butter or grease, directly reducing fuel consumption costs.
  2. Motor: The industry’s first dedicated motor for wood pellet machine, the power output efficiency is increased by more than 10%, the power density of each center height can reach 3-5 times, the voltage and frequency have a wide range, and it is more suitable for operation under harsh environmental conditions and energy saving, safe and stable.
  3. Transmission: reducer, a special reducer for pellet machine developed and produced by ourselves, shields the short board of ordinary industrial reducer in the operation of pellet machine, adopts finite element design, parallel hard tooth surface gear transmission, and has equal strength step by step. Even if the high temperature, lack of oil, or load increases to 3-4 times normal, it can still operate normally.
  4. Safety: The lubrication level of the whole machine is designed based on the lower maximum allowable oil temperature, and the loading cycle is forced to air cooling, the oil temperature is low and constant, and the spray lubrication shields the characteristics of short-term deterioration caused by the agitation of the lubricating oil, and the oil replacement cycle Extend 1.5 times.
  5. Modularization: To break the situation that the biomass pellet machine in the industry adopts ordinary motors and ordinary industrial reducers, and use self-developed pellet machine special motors and reducers to provide power and transmission. The design of the whole machine becomes more compact, the complex process and small parts are reduced, the modular production and assembly of standard parts are realized, and the quality, performance, and safety factor of stable operation are increased by 3-4 times.

MZLH320 series ring die wood pellet machine ensures high capacity and efficient control of the pelleting process. The wood pellet mill machine is dimensioned for large and designed with exchangeable wear parts.

  • Power: 37KW
  • Capacity: 600-800KG/H
  • Pellet Size: 6-12mm

MZLH350 series ring die wood pellet making machine has wide adaptability. According to different raw materials, different pellets can be produced. Larger feeders increase production capacity and ensure production efficiency.

  • Power: 55KW
  • Capacity: 800-1000KG/H
  • Pellet Size: 6-12mm

This ring die electric wood pellet mill is recommended for straw pellet production plant. Due to the power and voltage, it is not recommended for household pelletizing. It is very suitable for making straw pellets, alfalfa pellets, forage pellets, wood sawdust pellets, and other biomass pellets.

  • Power: 110KW
  • Capacity: Capacity: 1.5-2T/H
  • Pellet Size: 6-12mm

The MZLH520 series wood pellet maker has a larger ring die and pelletizing chamber to ensure high-efficiency straw pellet production. In order to adapt to lighter raw materials, we have added a forced feeder.

  • Power: 160KW
  • Capacity: 3-4T/H
  • Pellet Size: 6-12mm

MZLH768 series large commercial wood pellet press is mainly used for the production of biomass pellets. Enlarged feeders and larger ring die sizes are more suitable for straw pellet plants.

  • Power: 250KW
  • Capacity: 5-7T/H
  • Pellet Size: 6-12mm

RICHI wood pelletizer for sale. 27 years of pelleting plant experience, professional design and manufacturing team, overseas installation engineers, competitive factory direct sales prices. Advanced pelleting process technology.

  • Power: 280KW
  • Capacity: 8-10T/H
  • Pellet Size: 6-12mm

Cooling machine

The temperature of the pellets during compression molding is as high as 80~90℃, the structure is relatively loose, and it is easy to be broken. After being cooled to room temperature by a cooler, the pellets have high strength and are not easily broken before they can be bagged into the warehouse or sent into the drum by conveyor and elevator. The warehouse proceeds to the next step.
