process such as crushing, grinding, abrading or blasting. Fumes – particles formed when a volatilized solid, such as a metal, condenses in cool air. The physical change is often accompanied by a chemical reaction, such as oxidation. Mists – mists are formed when a finely divided liquid is suspended in the air.efficient crushing and grinding circuits using both power and model-based methods. We can design bankable circuits and provide operating advice to maximize milling efficiency, considering both steel and power consumption. Our practical experience also ensures that we recommend effective circuit configurations that offer ease of operation
