Zusammenfassung: | PURPOSE:To prevent accumulation of crushed material and to improve grain refining efficiency due to the lower crushing rollers by forming the lower crushing rollers into a parallel pair and forming the nipping dots to the respective upper crushing rollers and fitting the counter knives between the lower crushing rollers and to the proper parts of the outside thereof. CONSTITUTION:The supplied bulky material is crushed by a pair of upper crushing rollers 2, 3 and fed into the space A formed to the lower part. The lower crushing rollers 4, 5 are simultaneously driven and the crushed material is pulverized by both the lower crushing rollers and the respective upper crushing rollers 2, 3 in cooperation with the counter knives 20, 21, 22 together with crushing in the nipping dots (a), (b) and pulverized to fine grain not larger than the size of a cell and not higher than the height of the crushing blades 23, 24 and thereafter discharged to the lower part. Further one part of the crushed material is not pulverized by the lower crushing rollers 4, 5 and retransferred to the feed side of the bulky material according to rotation of the rollers 2, 3 and again crushed thereby. |
