給馬達供電的控制模塊應考慮其輸出阻抗盡量小，防止負載時輸出電壓大幅度下降，影響振感。柱式電機檢驗或測試堵轉(zhuǎn)電流時，堵轉(zhuǎn)時間不宜過長小于秒為宜，因為堵轉(zhuǎn)時所有的輸入功率都轉(zhuǎn)化為熱能，時間過長可能導致線圈溫升偏高而變形，影響性能。
有些礦石在好的破碎腔破碎到一定粒度后，經(jīng)過反擊板和轉(zhuǎn)子之間的空隙而排至第二破碎腔中，繼續(xù)受到反復打擊，直至粒度變小后才由碎石機底部排礦口排出。錘式碎石機錘式碎石機經(jīng)高速轉(zhuǎn)動的錘體與物料碰撞面破碎物料，它具有結(jié)構(gòu)簡單，破碎比大，生產(chǎn)效率好的特點，可作干濕兩種形式破碎，適用于礦山水泥煤炭冶金建材公路燃化等部門對中等硬度及脆。
