有爆炸破碎、機械破碎、水射流破碎和熱力破碎等四種。研究巖石破碎的主要任務是：揭示破碎巖石的能耗和破碎效果間的配件，價格優惠。產業乃至碎石機行業的競爭就是文化的競爭，圍繞自主創新的一個最關鍵的問題就是對于知識的尊重，對人才的尊重和對知識產品的尊重。
我國的碎石機行業在自主創新的道路上做出了很多有益的貢獻，在堅持自主品牌的道路上做的十分出色，不僅實現了產業的自身發展，堅定了產業的自信心，他們應該成為我國很多碎石機行業的榜樣。水泥窯主要用于煅燒水泥熟料，分干法生產水泥窯和濕法生產水泥窯兩大類。回轉窯在建材冶金化工環保等許多生產行業中，廣泛地使用回轉圓筒設備對固體物料進行機械物理或化學處理，這類設備被稱為回轉窯。建筑工程施工平面圖布置建筑工程施工平面圖布置單位工程施工平面圖是單位工程施工構造計劃中的緊張組成部分，是對一個建筑物或構筑物的施工現場的平面規劃和空間布置。
公道的施工平面布置對于順利實行施工進度計劃黑白常緊張的，對現場的文明施工工程本錢工程質量和安全生產都會產生直接的影響。用途廣泛應用在冶金工業建材工業筑路工業化學工業與硅酸工業中，適用于破碎中等和中等以上硬度的各種礦石和巖石。圓錐工作原理圓錐碎石機工作時，電動機的旋轉通過皮帶輪或聯軸器圓錐傳動軸和圓錐碎石機圓錐部在偏心套的迫動下繞一周固定點作旋擺運動。
