Ball milling as an important pretreatment technique in
The size and quantity of grinding balls, the presence of wetting liquid, milling speed, and temperature are important factors in an attritor mill. The drawback of attritor mills is the extremely high degree of wear during operation on the mill bodies, which increases the overall cost of mill operation and causes contamination of the biomass [48 ...
