摘 要
輥磨機（又稱立磨）是一種用途很廣的粉磨兼烘干設備，立式輥磨是目前世界上比較先進而且成型的技術，它不但具有能耗低、產(chǎn)量高、維修工作量小等優(yōu)點，而且運轉(zhuǎn)周期長，適合與大型窯外分解窯配套。在用立磨粉磨物料時，磨輥和磨盤的磨損比較大、國外一些立磨生產(chǎn)廠在磨輥和磨盤等易碎件上使用了更耐磨的材料。因此，其生產(chǎn)的立磨成功地用于水泥和礦渣粉磨中。本文總結了這些立磨的易損件材料選擇的一些成功經(jīng)驗，并將其性能及其磨損情況進行對比分析。
現(xiàn)代的立磨隨著液壓技術的發(fā)展普遍采用液力加壓系統(tǒng)向磨輥加力，壓力加載是通過油缸實現(xiàn)的，調(diào)控液壓系統(tǒng)的壓力可改變油缸對磨輥壓力的情況，可隨意調(diào)控磨輥對物料粉磨力的大小。液壓系統(tǒng)內(nèi)的儲能器對磨輥設施具有保壓和過載緩沖的作用，可吸收一部分過載壓力。

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 .
