1、精選優質文檔-傾情為你奉上旋回破碎機設計摘 要 隨著社會的前進，原材料消耗不斷增加，導致富礦資源日益枯竭，礦石品位日趨貧化。以我國冶金礦山為例，鐵礦石平均品位31%,錳礦石品位22%。絕大多數的原礦需要破磨和選礦處理后才能成為爐料。旋回破碎機生產效率高，排料粒度小而均勻，可將礦巖從350mm破碎到l0mm以下的不同級別顆粒，可以滿足入磨粒度需要，成為金屬礦山選礦廠的主要破碎設備。 20世紀50年代初期，國內在仿原蘇聯的彈簧破碎機的基礎上，開發了國內自己的破碎機。這種破碎機的設計思想最基本點是靠排料口大小控制產品粒度，破碎物料的方法是靠動錐單向擠壓和彎曲研磨作用破碎物料，物料之間相互作用很弱，破

2、碎過程幾乎沒有選擇性。 近來國內外開發的新型高效旋回破碎機破碎物料應用的范圍不斷擴大，破碎產品粒度小，破碎效果顯著。目前旋回破碎機正向著大型、高效、可靠、節能、降耗和自動化方向發展。關鍵詞：礦山，破碎，旋回破碎機Abstract As society advances, the increasing consumption of raw materials, leading to the depletion of high-grade ore resources growing, increasingly depleted ore grade.
