HRM型立磨设计打印稿

摘要

辊磨机（又称立磨）是一种用途很广的粉磨兼烘干设备，立式辊磨是目前世界上比较先进而且成型的技术，它不但具有能耗低、产量高、维修工作量小等优点，而且运转周期长，适合与大型窑外分解窑配套。在用立磨粉磨物料时，磨辊和磨盘的磨损比较大、国外一些立磨生产厂在磨辊和磨盘等易碎件上使用了更耐磨的材料。因此，其生产的立磨成功地用于水泥和矿渣粉磨中。本文总结了这些立磨的易损件材料选择的一些成功经验，并将其性能及其磨损情况进行对比分析。

现代的立磨随着液压技术的发展普遍采用液力加压系统向磨辊加力，压力加载是通过油缸实现的，调控液压系统的压力可改变油缸对磨辊压力的情况，可随意调控磨辊对物料粉磨力的大小。液压系统内的储能器对磨辊设施具有保压和过载缓冲的作用，可吸收一部分过载压力。

Abstract

The roller gringing machine (has name to stand rubs )is one kind of use very broad powder rubs concurrently dries the equipment .The vertical roller rubs is in the present world quite, advanced the technology which moreover takes shape ,it not only has the energy consumption lowly .the output high ,the service work load young and soon the characteristic ,moreover the operating cycle is long ,suit decomposes the kiln with the large –scale kiln outside to from acompleteset . To reduce the abrasion of rollers and millstones of the roller mill , the high quality materials have to be used , and then the roller mills arc able to be used to produce cement and GGBS successfully in abroad . In this paper , the successful experience to select the materials for the parts of the mill was sunnrized with the comparison of materials properties and rate of abrasion .

The modern age stands rubs uses the fluid strength compression system along with the hydraulic technique development to the roll thrust augmentation .the pressure load is generally realizes through the cylinder ,the regulation hydraulic system’s pressure may change the cylinder to the roll thrust augmentation condition ,may regulate the roll to rub the strength at will to the material powder the size . In hydraulic system’s accumulator has to the roll facility guarantees pressers and overloads the cushioning effect ,may absorb a part of overload pressure .
