The biomass size reduction occurs due to impact, compression, shear, and abrasion/attrition. In case of impact and compression, force is applied to materials instantaneously (as in ball mills, hammer mills). Whereas, in case of shear and attrition, energy is transferred during a longer contact time (as in knife mills, attrition mills).
