高细风选粉碎机组的设计

针对目前普通有筛粉碎机粉碎细度较低 ,满足不了诸如甲鱼、鳗鱼、对虾等动物对高细度饲料的需要 ,采用无筛粉碎、风选方法 ,设计了高细风选粉碎机 。

MAKING OF THE EQUIVALENT MATERIALS USED FOR STUDYING ROCK RIPPABILITY

Based on the characteristics of the ripping of rock, the simulated conditions that would be satisfied by the prototype ripping and the model ripping have been derived in this paper. In order to .nanufacture the satisfying equivalent materials for the model ripping, a new method has been set up, and the materials, which can simulate the prototype rock "Hawkesbury sandstone", have been made by using the methed.
