Rice Husk Pellet Mill for Agricultural Forest Waste

Brief Introduction

The agricultural and forestry waste rice husk pellet mill is a biomass molding and processing equipment specifically designed for processing rice husk materials from agricultural and forestry waste. Rice husks are a typical agricultural by-product, high in silica, highly abrasive, and loosely structured, making them prone to rapid mold wear, poor forming rate, and large fluctuations in output when processed by ordinary pellet mills. The agricultural and forestry waste rice husk pellet mill adopts highly wear-resistant mold components and a forced feeding mechanism, and is optimized for the material characteristics of rice husks. This mill can compress large quantities of accumulated waste rice husks into high-density, standardized biomass pellets. The equipment operates stably and is suitable for rice processing plants, grain-producing areas, agricultural and forestry solid waste treatment centers, and biomass fuel production enterprises, achieving the harmless and resource-based disposal of agricultural and forestry waste such as rice husks.

Working Principle

The rice husk pellet mill for agricultural and forestry waste adopts a purely physical high-pressure extrusion molding process, requiring no binders throughout the entire process. After screening and moisture conditioning, the rice husks are fed into the mill's hopper. A forced feeding mechanism steadily conveys the loose rice husks into the molding cavity. Pressure rollers continuously crush and extrude the rice husks, activating the lignin within through frictional heating. Under high pressure, the material is extruded through the die holes and cut into uniform-length pellets by a cutter. After cooling and shaping, the finished rice husk pellets are obtained. The entire production process is automated and suitable for large-scale continuous processing of agricultural and forestry waste.

Suitable Raw Materials

This rice husk pellet mill is designed to process rice husks, a type of agricultural and forestry waste, produced from rice processing. It is also compatible with rice bran and husks, and can be mixed with small amounts of sawdust, chopped straw, and fruit shells for pelleting. The raw material moisture content is controlled at 12-17%. Raw rice husks can be easily screened and impurities removed before being fed into the mill. With minimal pre-treatment steps, it facilitates on-site processing of agricultural and forestry waste.

Application Areas

Rice husk pellet mills produce rice husk pellets that can be used as clean fuel for industrial boilers, factory heating, drying kilns, and biomass power plants. The finished pellets can be sold and traded, or used as organic fertilizer substrate, livestock bedding, and raw materials for carbonization. These rice husk pellet mills can locally dispose of rice husks and other agricultural and forestry waste piled up in fields and rice mills, solving problems such as land occupation, dust pollution, and illegal burning of rice husks, transforming low-value agricultural and forestry waste into high-value products.

Details

1. HUIXIN Gearbox: Heavy-duty HUIXIN gearbox provides adaptive torque for fluctuating loads from silica-rich husk and woody forest fiber.

2. Rotating bracket: Reinforced rotating bracket suppresses vibration from heterogeneous mixed material feeding.

3. Reducer: Precision matched reducer maintains reliable power transmission under alternating abrasive and fibrous working conditions.

4. 304 stainless steel dust cover: 304 stainless steel dust housing resists silica abrasion and mild ash corrosion from mixed biomass dust.

5. Internal lifting knife: Built-in internal lifting knife cuts tangled woody fibers and prevents material bridging in the forming cavity.

6. Adjustable blades: Adjustable blades calibrate feed thickness to suit both granular rice husk and shredded forest fiber.

Unique Advantages

1. Mill assembly: Universal wear-resistant ring die and roller set, optimized for rice husk mixed with forest waste instead of single feedstock.

2. HUIXIN gearbox: Heat-resistant HUIXIN heavy-duty gearbox, stable running under frequently changing raw material formulas.

3. Stainless dust cover: Integrated 304 stainless dust shield instead of painted carbon steel, anti-scouring for mixed silica and wood dust.

4. Bottom feeding reducer: Improved anti-bridging under-feed reducer prevents fiber arching and husk compaction blockage.

5. Cooling system: Adjustable circulating air cooling balances pellet hardness and reduces finished pellet breakage and powder rate.
