格子磨是拜尔法生产氧化铝的重要设备,其主要作用是将铝土矿破碎到一定的粒度,增大物料的比表面积,为高压溶出提供原料。格子磨属湿法边缘传动的短磨,其传动系统主要由同步电动机、离合器、长传轴、大齿圈、小齿轮及微动装置组成(见图1)。大齿圈是格子磨重要的构成部件,安装在格子磨筒体出料端与其啮合的小齿轮一起构成传动系统的齿轮副,由于格子磨转速高,研磨体冲击力大,传动大齿圈易出现故障,最常
Plaid mill Bayer process alumina production is an important device, its main role is to crush the bauxite to a certain particle size, increase the specific surface area of the material, to provide high-pressure dissolution of raw materials. Lattice mill is a wet edge drive short mill, the transmission system is mainly composed of synchronous motor, clutch, long shaft, gear ring, pinion and micro-devices (see Figure 1). The large ring gear is an important component of the lattice grinding machine, which is arranged on the output end of the lattice grinding barrel and engages with the pinion which meshes with it to form the gear pair of the transmission system. Due to the high rotating speed of the lattice grinding body and the large impact force of the grinding body, Failure, the most common
