1、XXX大學(xué)本科生畢業(yè)設(shè)計(jì)（論文）高壓輥磨機(jī)的設(shè)計(jì)學(xué)生姓名：______________學(xué)號(hào)：______________班級(jí):______________專業(yè)：______________指導(dǎo)教師：______________2015年4月摘要世界5%左右的能耗用于礦物的選別，而選礦中80%左右的能耗用于對(duì)原物料的粉碎。經(jīng)濟(jì)的高速發(fā)展導(dǎo)致了能源的大量消耗，選礦處理的原礦由于“貧細(xì)雜”等更加難選。礦石品位的降低，有用礦物嵌布粒度減小等現(xiàn)象更增加了選礦能量的消耗。同時(shí)，由于粉碎方式的改變，改善礦石粉碎過程中礦物之間的解離狀態(tài)，提高選礦回
2、收率，最終提高我國(guó)礦產(chǎn)資源的利用效率。因此研究新型粉碎技術(shù)與設(shè)備具有重要的經(jīng)濟(jì)、社會(huì)和環(huán)境效益。高壓輥磨機(jī)作為一種超細(xì)碎設(shè)備具有單位破碎能耗低、單位鋼耗低、單位處理能力大、破碎產(chǎn)品粒度均勻、占地面積少、設(shè)備作業(yè)率高等特點(diǎn)，受到國(guó)內(nèi)外專家和學(xué)者的關(guān)注，成為多碎少磨技術(shù)的發(fā)展趨勢(shì)。本論文對(duì)高壓輥磨機(jī)進(jìn)行了總體設(shè)計(jì)。首先根據(jù)經(jīng)驗(yàn)公式，設(shè)計(jì)完成給定任務(wù)量所需的高壓輥磨機(jī)的各部分參數(shù)，如輥徑，輥寬、輥磨力，功率等參數(shù)。然后是結(jié)構(gòu)設(shè)計(jì)和整體規(guī)劃。最后進(jìn)行非標(biāo)準(zhǔn)件的尺寸確定與標(biāo)準(zhǔn)件的選型。關(guān)鍵詞：高壓輥磨機(jī)；組合輥；機(jī)械設(shè)計(jì)AbstractAbo
