1、XXX大学本科生毕业设计(论文)高压辊磨机的设计学生姓名:______________学号:______________班级:______________专业:______________指导教师:______________2015年4月摘要世界5%左右的能耗用于矿物的选别,而选矿中80%左右的能耗用于对原物料的粉碎。经济的高速发展导致了能源的大量消耗,选矿处理的原矿由于“贫细杂”等更加难选。矿石品位的降低,有用矿物嵌布粒度减小等现象更增加了选矿能量的消耗。同时,由于粉碎方式的改变,改善矿石粉碎过
2、程中矿物之间的解离状态,提高选矿回收率,最终提高我国矿产资源的利用效率。因此研究新型粉碎技术与设备具有重要的经济、社会和环境效益。高压辊磨机作为一种超细碎设备具有单位破碎能耗低、单位钢耗低、单位处理能力大、破碎产品粒度均匀、占地面积少、设备作业率高等特点,受到国内外专家和学者的关注,成为多碎少磨技术的发展趋势。本论文对高压辊磨机进行了总体设计。首先根据经验公式,设计完成给定任务量所需的高压辊磨机的各部分参数,如辊径,辊宽、辊磨力,功率等参数。然后是结构设计和整体规划。最后进行非标准件的尺寸确定与标准
