Vertical grinder

Abstract

The invention discloses a vertical mill, which comprises the following parts: feed inlet, discharge port, grinding roll, grinding disk, pressuring device, grinding roll, grinding disc gap adjusting device, rotary bearing, bearing support, deceleration device and stand, wherein the stand is fixed on the ground; the bearing support is set on the stand or ground directly; the grinding disk is set on the bearing support through rotary bearing; the output end of deceleration device connects the rotary coil of rotary bearing through flange, gear or other driving part, which can be gear deceleration device and belt deceleration device or the combination with two devices on the bearing support, stand or ground directly.

Description

Technical field [0001] The invention relates to a vertical mill, in particular to a vertical mill used for grinding various materials in industries such as metal mines, non-metal mines, energy sources, and new materials. Background technique [0002] The vertical mill commonly used in industry is a kind of roller mill. Its basic principle is to place the material to be ground between the grinding roller and the grinding disc, and use mechanical force such as spring force and hydraulic pressure or centrifugal force generated by rotation. It is crushed and crushed. This kind of grinding equipment using the principle of material bed extrusion and crushing has the characteristics of higher grinding efficiency, lower power consumption and less wear than the grinding equipment using shear and impact force. There are many types of vertical mills. Here, a widely used MPS vertical mill with a rotating disc and a relatively stationary roller (not revolving around...

AI Technical Summary

Problems solved by technology

Therefore, the performance requirements of the vertical mill reducer are high, the structure is complex, the manufacture is difficult, and the cost is expensive, which generally accounts for about 1 / 3 of the entire machine cost.
