The wrong liner design will increase power and steel consumption as well as reduce the grind and throughput of the mill Liners not only come in different designs they are available constructed from different materials Liners may he built from MANGANESE STEEL for rod mills and ball mills that use bigger than two inch balls
Selection and design of mill liners is introduced in the context of shell liners in ball mills The wear data is accumulated on the surface of the liner by 3D discrete element method DEM
Ball Mill Design Parameters Size rated as diameter x length Feed System One hopper feed Diameter 40 – 100 cm at 30° to 60° Top of feed hopper at least 15 meter above the center line of the mill
Working Principle Operation The apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the
