The OK™ Mill was originally designed for cement grinding. In 2017 we released the OK™ vertical roller mill for raw materials grinding. The OK™ Mill’s modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between vertical roller mills regardless of size and application.Alumina Balls and Satellites. Union Process is the one source for 90 , 94 , 99.5 and 99.9 alumina media. 90 alumina is available in satellites and rod cylinders. 94 alumina balls have excellent wear resistance with higher impact strength to save running costs with less contamination. They have great wear rate generally better than 90 or 99.The mill is designed to handle a total ball charge of 324.5 t at 100 loading with a percentage filling of 29.5 in both the chambers. Both the chambers of the cement mill were charged with 80 of the designed charge,.
Jan 31, 2015 balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25 of total ball weight. If the quantity of charge is very less then milling balls will.The most important characteristics of a primary crusher are the capacity and the ability to accept raw material without blockages. A large primary crusher is expensive to purchase than a smaller machine. For this reason, investment cost calculations for primary crushers are weighed against the costs of blasting raw material to a smaller size.RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application.
