全書分上下兩冊(cè)，共近萬字。本書參閱了國內(nèi)外上萬篇條文獻(xiàn)，收集了國內(nèi)外幾千家設(shè)備生產(chǎn)廠家的資料和礦山企業(yè)的生產(chǎn)實(shí)踐資料，全面系統(tǒng)地反映了我國采礦設(shè)備的最新制造水平以及國內(nèi)外采礦設(shè)備在我國金屬礦山大型煤炭礦山的應(yīng)用情況。
要在激烈競爭的市場中脫穎而出，就必須走差異化競爭之路，以此造就局部領(lǐng)域供不應(yīng)求的局面，獲取高于同行平均水平的利潤率。黎明機(jī)械提供顎式碎石機(jī)、反擊式碎石機(jī)、錘式碎石機(jī)、圓錐式碎石機(jī)、復(fù)合式碎石機(jī)、雙輥碎石機(jī)等，為不同類型的破碎提供科學(xué)的破碎設(shè)備和方案。
