In order to obtain a higher hardness is now made of alloy elements to replace part of a strengthening element carbon steel liner wear performance, made a rare abrasion resistant steel. The hardness of the steel itself and general steel liner wear close, but air-cooled after quenching hardness can reach HRC50, using this material mill liner and ring hammer crusher hammer, use in power plants have achieved good results. According to the measured use of rare earth metal wear resistant steel crushing one ton of coal consumed amount of 0.0288 g, while the use of Mn13 about 0.11 grams. When coal grindability coefficient 0.37; coal mineral content W = 1.4%, the rare earth wear-resistant cast steel mill liners or Mn13, the wear rates were 10.5 g and 34.8 g liner wear prices, the former nearly twice the wear resistance than the latter. Impact mill liner What causes it? Countermeasures to see the following presentation analyzes the impact of the media often crushing mill crushing medium: all types of mining material (manganese, copper, tungsten ore, chrome ore, etc.), all kinds of stone (limestone, granite, gneiss basalt, gray rock, etc.) used in coal power industry. Medium hardness index is an important basis for decision liner wear failure, the higher the hardness, the shorter the life of the liner, on the contrary, the growth cycle. Fuel power plant coal is the main mill liner wear milled medium cost, coal grindability coefficient around the country generally between 0.8--2.0, if too much coal gangue incorporation, sand, stone not only the lack of heat, and can grind the poor, will inevitably lead to premature failure of the liner.
