At present,coal mining operations generally use the underground and open-air job in two ways, and 90% of coal mines are by way of underground work,it generally refers that equipment mechanical wear damage is mine downhole mechanical wear and tear.mechanical Downhole operation mainly has the following characteristics:First, humidity is relatively large, the moisture contained much in the air . this is the main reason for severe mechanical erosion.Studies have shown that general mine air humidity is 80% to 90%, equivalent to the coal mining equipment soaked in water,and most of the metals will be oxidation reaction in the water .Second , coal mining machines often convey large size coal briquette ,for a  long time .

mining coal equipment will suffer serious damage from mechanical erosion and mechincal abrasion . typical mining equipments including ventilation fan ,air compressor blades and shaft wear; all kinds of pump impeller and guide wear wheel; various rail wear; corrosion and hoist derrick, conveyor bracket etc.

Facing such large equipment replacement and maintenance cost , chemshun ceramics as china  wear resistant ceramic manufacturer suggest miners to use wear ceramic liner  for equpment wear protection solution . alumina ceramic liner has Mohs hardness 9 grade , only less than diamond . at the same time , Chemshun ceramics can offer ceramic liner with all kinds of shapes. like ceramic tube ,  hex tile mat , alumina ceramic tile etc.  www.chemshun.com    office@chemshun.com
