The Gallnuts of Quercus lnfectoria are pulverized to required partical size and extracted in aqueous media. 將此物按一定的大小粉碎，放在溶液中萃取。
The unit breaks up agglomerates, reduces particle size, overcomes surface forces and speeds up chemical reactions involving insoluble materials. 該分散器可粉碎團塊，減小顆粒尺寸，克服表面張力，加速不溶物質間的反應。
The seive mainlyfunctions to limit the particle size of the material and increase grinding action. 限制過篩物料粒徑和增加對物料的破碎作用。
The fragmentation of clarain and culm tends to be severely with the increase of particle size, bed temperature and combustion time. 而暗煤顆粒則因相反的原因不發生破碎或僅發生輕微破碎。
