Grinding mills are a critical component in mining processing and downtime can lead to costly production losses. With a Motornostix solution you can know at all times the health status of the motor, gearbox, pinion bearings and trunnions so that breakdowns can be prevented and maintenance tasks can be performed timeously.
Grinding is continuous and fully integrated with subsequent flotation operations. SAG or AG mills. The crushed products are ground in SAG or AG mills. The self-grinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.
Mining Applications. Cast High Chrome grinding media has been designed to effectively liberate a wide variety of minerals such as gold, silver, lead, zinc, copper, iron, etc during the comminution process. The chemistries have been designed for use in mining applications to ensure optimal product performance.
