There are many manufacturers to product grinding balls of ball mills, the key is when you buy the balls must be clear which kinds of grinding balls wear is the highest.
Manganese steel material and the traditional form of the ball mill liner are not appropriate, the combination of solid liner liner epoch-making design has great advantages, completely solve the broken bolts, leakage powder problem, the maintenance of more than 98% reduction; combination liner can give full play to a variety of high hardness materials, quenching hardness, to play the best anti-wear performance.
In the dry process, power plants, cement plants should give priority to dual medium quenching, low chromium alloy steel liner or high chromium cast iron, high chromium cast steel liner, select high hardness of high chromium cast iron ball. Low chromium alloy steel has good economic benefits; in the mine wet process, from the economic point of view, give priority to high and medium carbon alloy steel liner or Cr10 ~ Cr20 series of low carbon content of cast iron Lining and high hardness of low-chromium alloy ball. But the ball is greater than 110mm and diameter should be considered with high-carbon alloy steel forging the ball.
Matching of the ball mill liner and the ball mill ball should be the "substrate system" point of view, lining life of two overhaul period to ensure that under the premise of the wear resistance of the ball should choose the best. The hardness of liner should be greater than HRC50, the hardness of chrome molybdenum alloy casting ball should be greater than HRC52, the hardness of forged alloy steel ball should be greater than HRC55. As far as possible the general choice of anti-wear performance of the best ball.
Currently more market applicable, cost-effective is a wear-resistant ball Ming alloy, the kind of grinding ball Ming content ≥ 10% -14%, hardness HRC ≥ 58, high-alloy cast ball, mainly used in governance gold mine , cement, building materials, thermal power, flue gas desulfurization, magnetic materials, chemicals, coal slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand and so on.
