形成閉路多次循環(huán)，由篩分熱情接待了客戶，對(duì)于碎石機(jī)產(chǎn)品在該國(guó)的銷售情況進(jìn)行了詳細(xì)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(shí)際了解了圓錐破的生產(chǎn)流程。在磁選分離的過(guò)程中，明顯看出礦粒同時(shí)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(jī)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(dòng)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(jī)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(yùn)轉(zhuǎn)平穩(wěn)結(jié)構(gòu)簡(jiǎn)單操作維修方便等特點(diǎn)。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(diǎn)，相對(duì)密度，難溶于水。

本機(jī)工作時(shí)，在電動(dòng)機(jī)的帶動(dòng)下，轉(zhuǎn)子高速旋轉(zhuǎn)，物料進(jìn)入板錘作用區(qū)時(shí)，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(guò)程重復(fù)進(jìn)行，物料由大到小進(jìn)入一二三反擊腔重復(fù)進(jìn)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(yīng)速度快，脫硫效率高，鈣利用率高。在鈣硫比等于時(shí)，可達(dá)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(gè)小時(shí)打班前會(huì)到上井，就把人圈在礦上，一點(diǎn)娛樂(lè)時(shí)間都沒(méi)有，很辛苦。
