烏煤公司設計粒度為以下,冬天由于錫林郭勒盟地區氣溫偏低導致煤的凍塊大,煤的硬度也相應增大,碎石機不能達到設計生產能力,經測算冬天的小時生產能力為左右。生產工作人員及碎石機管理人員在生產管理過程發現,未經過碎石機破碎的原煤有粒度小于,這些煤不需要破碎就可以達到煤炭市場的要求,即破碎站在破碎過程中產生了一些無用功。
國家統計數據顯示，工業在我國呈現穩步發展的趨勢，加上政府相關鼓勵政策的出臺，更是奠定了工業在我國的重要地位。近年來，我國的破碎行業有了很大的發展，不僅技術進步，范圍得到擴展，就連效益都有了很大的提高。
然而，隨著鋼鐵企業的日益發展，煉鋼時產生的廢物，比如氧化鐵和一些其他不容物雜志，通常被稱為鋼渣，成為鋼鐵企業發展的一大頭疼問題。如何循環利用鋼渣呢在通俗的意義上來分，鋼渣的利用途徑大致可分為外循環和內循環，鋼渣的外循環主要是指用于建筑建材行業。
可以根據市場需要直接作為產品供混凝土生產摻用也可以根據需要調整細度及摻量配制成水泥出售。礦渣堆場設有一臺鏈斗卸車機，濕礦渣由鏈斗卸車機卸進礦渣堆場堆存，礦渣的轉運由礦渣堆場上的兩臺裝載機喂入帶式輸送機上方的受料斗，由帶式輸送機送入配料站的礦渣倉內。
而我國盡管白鎢礦已探明儲量376萬t，占世界鎢礦總儲量的71%，但由于一些大型、超大型鎢多金屬礦床的礦石物質成分復雜，嵌布粒度細，選冶技術尚未基本解決，因而現階段開采仍以石英脈型黑鎢礦為主，占全國采出礦量的90%。一）保持刀架的運動軌跡平行的輥軸，以避免出現錐度切割后，這將影響破碎效果。
另一方面同相關職能部門，但在未來數十年的漫長發展中這些是遠遠不夠的。
