衬板和击锤是电力、煤炭、建材工业磨制煤粉、生产水泥的重要设备球磨机及前置设备破碎机上必不可少的易磨损部件,长期以来存在着磨损抗力低,使用寿命短,消耗量高及断裂等问题。它的消耗量仅次于钢球。目前国内的一般消耗水平:电力工业为0.09～0.1公斤/吨煤,建材工业为0.2～0.3公斤/吨水泥。全国每年磨制煤粉及水泥产品约4～5亿吨,需消 Liner and hammer is the power, coal, building materials industry pulverized coal, cement production equipment, an important ball mill and pre-crusher crusher indispensable parts, for a long time there is low wear resistance, short life expectancy, consumption High volume and fracture and other issues. It consumes second only to the ball. At present, the general consumption level in China is 0.09 ~ 0.1 kg / t coal in power industry and 0.2 ~ 0.3 kg / t cement in building material industry. Pulverized coal and cement products each year about 4 to 500 million tons of grinding, to be eliminated
