形成閉路多次循環(huán)，由篩分熱情接待了客戶，對于碎石機產(chǎn)品在該國的銷售情況進行了詳細的交流。隨后，客戶在徐經(jīng)理的陪同下參觀了公司的圓錐破生產(chǎn)基地，實際了解了圓錐破的生產(chǎn)流程。在磁選分離的過程中，明顯看出礦粒同時受到兩種力的作用，一種是磁力，它使礦粒吸向圓筒;另一種是機械力，它包含有顆粒的重力、離心力、慣性力、流體阻力、摩接力、顆粒與顆粒之間的吸力和排斥力.以及分選介質(zhì)的流體動力阻力等，它們阻礙礦粒被吸向圓筒。
如果礦粒所受的磁力大于所受的機械力之和，則吸附在圓筒表面上，成為精礦;反之則仍留在礦漿中隨礦流排出，成為尾礦。具有破碎比大能耗少運轉(zhuǎn)平穩(wěn)結(jié)構(gòu)簡單操作維修方便等特點。是一種真正的多用途好的率低成本的新型破碎設(shè)備。熔點，相對密度，難溶于水。

本機工作時，在電動機的帶動下，轉(zhuǎn)子高速旋轉(zhuǎn)，物料進入板錘作用區(qū)時，與轉(zhuǎn)子上的板錘撞擊破碎，后又被拋向反擊裝置上再次破碎，然后又從反擊襯板上彈回到板錘作用區(qū)重新破碎，此過程重復進行，物料由大到小進入一二三反擊腔重復進行破碎，直到物料被破碎至所需粒度，由出料口排出。脫硫反應速度快，脫硫效率高，鈣利用率高。在鈣硫比等于時，可達到以上的脫硫效率，采用高鈣活性脫硫劑，不但是一種環(huán)保節(jié)能理想的脫硫劑，而且含量高，消溶特性好，活化特性大。我打算寫辭職信，不在礦上干。
煤礦的班倒，一般都得個小時打班前會到上井，就把人圈在礦上，一點娛樂時間都沒有，很辛苦。
