The wood crusher takes logs, lumber, lumber trimmings, bamboo, coconut shells and straw. Log diameter is the one limit to watch: the largest log the machine accepts is 190mm, and logs of 180mm or less are recommended for steady work. Staying under that figure keeps the rotor at speed and stops the inlet from choking.
Everything that goes in comes out at about 2mm to 20mm. That range covers both the fine material a briquetting or pellet line needs and the coarser chips a board press can use, so one output suits several buyers. The material goes to machine-made charcoal plants, artificial board factories, biomass power stations, paper mills, sawmills, feed mills and farms, and it also serves mushroom and edible fungus bases and landscaping projects.
Two shredding methods work in the same chamber. The blades cut and grind the material down, and the hammers break it further by high-speed impact. While the blades are cutting, the rotor throws up a high-speed airflow that carries the particles along and drives them back into the strike zone. Blades and hammers therefore act on the material again and again, which is where the deep shredding and the higher output per hour come from.
Zhengzhou Weiwei Machinery has built farm and biomass machinery since 1980 and holds ISO9001, CE, SGS and TUV certification. Wood crushers, sawdust machines, chippers, pellet machines and complete pellet lines from Weiwei are exported to the Americas, Africa, Southeast Asia and South Asia, with after-sales service and spare parts support.
