Causes of vibration of sodium feldspar vertical mill
2020-05-19
Sodium feldspar is one of the most common minerals produced. It is sodium aluminosilicate. It is a raw material for making glass and ceramics. It has high application value in the industrial field and a broad market.

Vertical mill is the best choice equipment for efficient processing and utilization of sodium feldspar, which can carry out fine processing of sodium feldspar, and the produced feldspar powder has high grade and good market benefit. What causes vibration when using sodium feldspar vertical mills?
 

1. Vibration caused by insufficient preheating.


Insufficient preheating, part of the heat input into the mill will be absorbed by the grinding body, resulting in inadequate heat exchange, the heat balance is broken, the friction of the material on the grinding plate increases, the fluidity decreases, and the bed plate is agglomerated and ground The powder crushing rate of the material crushed by the roller decreases and cannot be taken away from the grinding disc by the hot air, causing the material bed to fluctuate and cause vibration;
 

2. Vibration caused by insufficient feed.


The output of the vertical mill can be adjusted within a certain range, but when the feeding amount is too low, the moisture in the mill is reduced, the heat absorption is lower than the supplied heat, the material is quickly dried, the plasticity of the bed is reduced, and it is not easy to form a stable material layer, causing Vibration;
 

3. Vibration caused by over-grinding.


Increased raw material grindability, excessively high grinding pressure, and excessively high speed of the separator may cause an increase in suspended fines above the grinding disc, an increase in the density of dust-containing gas, resulting in an increased chance of collision between particles The process is disturbed, and the material that meets the fineness standard cannot be taken out of the vertical mill, the material balance is broken, and the proportion of fine material on the material bed is increased, causing vibration.
 

4. Other possible causes of vibration:


Vibration measuring element failure; loose roller skin and loose liner; feeding volume is too large, too small or unstable; system air volume is insufficient or unstable; grinding pressure is too high or too low; powder separator The speed is too high; the nozzle ring is clogged seriously.


Whether the operation of the vertical mill is stable is directly related to the production efficiency and production efficiency of the enterprise. Shanghai Clirik Machinery Co., Ltd. is a large-scale mill manufacturer with a high degree of specialization. It has high market recognition and good performance of the mill equipment. It adopts secondary classification and can produce 325 mesh-2500 mesh powder. The machine is versatile, the equipment is practical, and the investment cost is saved. The product quality is stable, the material stays in the mill for a short time, and it is easy to detect the particle size distribution and composition of the product.
