xx 理工大学学士学位论文 I S75 标准型圆锥破碎机设计摘要随着社会的前进,原材料消耗不断增加,导致富矿资源日益枯竭,矿石品位日趋贫化。以我国冶金矿山为例,铁矿石平均品位 31%, 锰矿石品位 22% 。绝大多数的原矿需要破磨和选矿处理后才能成为炉料。圆锥破碎机生产效率高,排料粒度小而均匀,可将矿岩从 350mm 破碎到 l0 mm 以下的不同级别颗粒,可以满足入磨粒度需要,成为金属矿山选矿厂的主要破碎设备。 20世纪 50 年代初期,国内在仿原苏联的弹簧破碎机的基础上,开发了国内自己的破碎机。这种破碎机的设计思想最基本点是靠排料口大小控制产品粒度,破碎物料的方法是靠动锥单向挤压和弯曲研磨作用破碎物料,物料之间相互作用很弱,破碎过程几乎没有选择性。近来国内外开发的新型高效圆锥破碎机破碎物料应用的范围不断扩大,破碎产品粒度小,破碎效果显著。目前圆锥破碎机正向着大型、高效、可靠、节能、降耗和自动化方向发展。关键词: 矿山;破碎;圆锥破碎机 xx 理工大学学士学位论文 II Abstract With the advance of society, the consumption of raw materials continue to increase, resulting in high-grade ore resources are depleted, the ore grade is increasingly depleted. China's metallurgical and mining, for example, iron ore average grade of 31%, manganese ore grade of 22%. The vast majority of ore crushing and beneficiation processing to e a charge. Cone Crushers high productivity, nesting and uniform particle size is small, you can mine rock from 350mm broken into different levels of particles less than l0mm granularity need to meet into the mill, metal mine concentrator crushing equipment. The early 1950s, domestic imitation of the former Soviet Union spring broken on the basis of the machine, to develop their own domestic crushers. Design idea of ? ? the basic points of this crusher is to rely on the size of the discharge opening to control the product particle size, broken materials, broken materials rely on dynamic cone-pression and bending abrasive material between the interaction is weak, the crushing process almost no selectivity. Recent domestic and international development of new efficient cone crusher range of materials applications continues to expand, broken product particle size is small, the crushing effect is significant. The cone crusher is toward large-scale, efficie
