Aug 22, 2006 · hardfacing of table liners of a vertical roller mill hi friends, I have a problem regarding the hardfacing of roll table liners and wear segments of MPS vertical roller mills. The mill is being used for grinding of limestone mainly at a rate of 215 tonnes per hour. I would be thankful if anyone can tell me which type (composition) of hardfacing to use to reduce the wear rate.
Vertical roller mills also occupy less floor space than ball mills. But despite these advantages, vertical roller mills are prone to premature bearing failures due to dust contamination. On average, cement mills have to change these bearings every 8 months to avoid failures, even though the calculated bearing life is .
Rocker arm design The rocker arm is a component connecting the grinding roller and the tension device. The pulling force produced by the hydraulic cylinder is transferred from the rocker arm to the grinding roller, so the rocker arm is the main stressed part in the whole pressing system, therefore, its design is directly related to the output and stability of the vertical mill.
Consequently, this paper present an automatic control system solu tion for vertical roller mill, aim to achieve the goal of high quality, lowcost, safe and civilized .
