Abstract
Method for processing plant material in which a first rotatable crushing roller with an outer generally cylindrical surface cooperates with a second adjacent rotatable crushing roller also having an outer generally cylindrical surface. The rollers, mounted with their surfaces positioned in close proximity to each other, rotate in opposite directions to receive and crush plant material. A rotatable impact rotor having a plurality of outwardly extending projections is mounted rearwardly of the crushing rollers for impacting plant material that has passed between the rollers to macerate the plant material that has been previously crushed by the rollers. The crushed and macerated plant material is diverted and again impacted one or more times by the outwardly extending projections of the impact rotor.
