The Loesche coal grinding mill range is divided into two serial types: Small twin mills constructed to individual specifications (LM D to LM D), with table diameters from 1,200 to 2,000 mm. Larger mills with two, three and four rollers and modular structures (LM D to LM D), with table diameters from 2,100 to 4,300 mm.
90 mm is the most common. 100 mm in rare cases; very hard, coarse feed. Coarser ball charges, gives good crushing. capability but: Too porous shorter retention. Less surface, less grinding. Can result in poor preparation for second chamber. if you overfeed (usually forced to underfeed) Extra wear.
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...
Comparison Between Ball Mill And Vrm bitween vrm and ball mill ball mill comparison with vertical roller mill. As we all know that the vertical roller mill and ball mill can be used in superfine stone powder making, the powder fineness made by ball mill can be controlled between 80 mesh to 400 mesh; however the vertical roller mill process ability can be adjusted ...
Advantages at a glance: Modular design and small footprint enable integration in existing grinding plants. Production increase in range of 1020 %, depending on the fineness, especially for smaller ball mill systems up to 100 tph. Quality improvement by use of the additional grinding stage, for example to improve the early strength while maintaining the original production rate
VRM has less flexibility in controlling particle size distribution. Overall ball miil is good option for Cement mill but only has limitations for higher capacity, as two ball mill to be installed for One VRM, but in case of breakdown one ball mill can be in operation. Trust this clear your clarifications on equipment selection for cment production.
For VRM the production capacity denotes both the capacity of grinding and drying of mill. The grindability affects the capacity of grinding, type of mill and roller pressure. The capacity of the mill is calculated Using G K * D Where, G is capacity of the mill, K1 is roller mill coefficient and D is table diameter. 2. PROCESS CONTROL OF VRM
