Factory Price Dia 80mm Iron Grinding Balls for Cement Plant And Mine Mills
Product overview of forged steel grinding media balls:
The crashed rate of forged steel grinding media balls is low,with the features of reasonable alloy elements ratio , Stable performance, low gas contained and low voidage rate,strict control of quenching process ,this kind steel balls
widely used in high capacity large grinding equipment.
Its proportion is slightly larger than casting ball.High impact, crushing and hearing force,can improve the
production obviously .
