How about the Lining Board in Micro Powder Grinder

Lining board is the key and vulnerable part of ball making equipment, and its unit consumption and service has a great relation with the working efficiency of grinding plant. On the basis of many years of theoretical research and practice, the experts of Daswell Machinery have had comprehensive knowledge on the unit consumption and service life of lining board.

Henan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China. We are dedicated to supplying our customers with best service and products, our major products include:portable jaw crusher,If you are interested in our products, please contact us freely: sales@daswell.com

The variate of the consumption of metal lining board used by micro powder mill machine is large, and according to the statistical material of ore grinding media in metal mines and non-metallic mines in many years, Daswell Machinery gets that as for the wet grinding of coarse and corrosive ores, the consumption of lining board for feeding every ton of materials can reach as high as 0.3kg; but as for the dry grinding of soft limestone ore cement clinker, the consumption of lining board may be only 0.5g/t, and if expressed by the lining board consumed by every KW•h of electricity, the consumption will be 23 g/kW•h and 0.05g/kW•h. The factors influencing the wear rate of lining board include granularity and hardness of materials to be ground, electricity consumed by grinding every ton of materials, diameter and rotating speed of the grinding mill, structural types of lining board, wear-resistance of the texture of lining board and percentage of remaining weight or size of lining board when it its abraded to scrap to original one.

In a micro powder mill grinder, the service life of the cylinder lining board is determined by four factors: resistance to macro impact failure damage grinding mill, resistance to macro fatigue failure damage, resistance to surface cut or cutting abrasion and resistance to surface micro impact and fatigue abrasion and various running conditions.
