chrome ball(Jinhong wear-resistant Materials Co. Ltd) our products are widely used in many fields,such as cement build materials,metal mine,coal slurry thermal power plant,chemical engineering,ceramic industry,dope industry ,light industry some as permaking and magnetic material etc.The grinding ball is high hardness,low breakage,low ware rate,low consumption and little fragmentation.Our annual production capacity is more than 20,000 metric ton.The surface hardness of ball will be raise further in using the course,and the wear resistance would gather hard,so can raise mill machine production capacity at the same time,and raise cements ratio surface area and reclaim ratio of the extractive mine. | ||||||||
