PROJECT PROFILE

Biomass crusher is applicable to a wide range of materials, covering a variety of biomass raw materials in agriculture, forestry, and industry. The specific classification is as follows:

I. Wood materials‌

Forestry waste‌: Branches, trunks, roots, stumps, birch, pine, ebony, etc. 

Wood processing residues: board skin, log core, lath, waste veneer, etc.

Industrial wood waste‌: Waste furniture, building templates, wooden pallets, Container wood boards, door and window frames, etc. 

II. Agricultural waste

Straw: Corn straw, rice straw, cottonwood, sweet potato vines, bean pods, reed straw, etc. 

Other crop residues: Peanut straw, hemp stalks, bamboo, sugarcane bagasse, etc. 

III. Industrial/domestic waste

House demolition waste: including nail wood, template waste, Packaging board, particle board, Carb artificial board, etc.

IV. Other biomass raw materials

Green waste: leaves, grass clippings, etc.

Feed raw materials: green fodder, sawdust, etc. are crushed for animal feed or pelleting

Energy fuel raw materials: crushed for biomass power plants, charcoal/pellet fuel preparation

PROJECT PROCESS

Detailed introduction to the working process of biomass crusher:

I. Pretreatment stage

--Raw material preparation Preparation

Remove metal impurities (nails, stones, etc.) and pollutants to prevent equipment wear. Dry raw materials with moisture content > 15% (such as rice husks need to be reduced to ≤ 10%). Pre-cut large-sized materials (such as stumps, straw bales) to ≤ 300mm 

II. Crushing process

‌--Primary crushing

The long-fiber materials are cut by the low-speed rotation (15- 30 rpm) of the double-axis shearing tool to achieve the tearing and decomposition of wood/straw. High-speed hammers (2000- 3000 rpm) impact brittle materials and use centrifugal force to complete the initial crushing.

‌--Particle size optimization

The crushed materials are graded by the vibrating screen, and the qualified particles (1-8mm) enter the finished product area. The unqualified materials are returned to the crushing chamber through the return system for cyclic crushing.

‌--Dust control

Integrated cyclone separator and bag dust removal system, dust emission concentration ≤ 20mg/m³. The finished products are transported to the storage bin by negative pressure wind.
