Size matter - when you need it to Capacity requirements for new cement and power plants and grinding units are consistently increasing. Over recent decades, continuous advances in manufacturing processes and design principles have helped us to produce reliable vertical roller mills of ever-larger size and potential capacity.
Feeders for Vertical Roller Mills. Williams industrial roller mills are used for a wide range of applications and materials, which means that the proper feeder selection is essential for high-capacity, trouble-free operation and more efficient production. You can customize your vertical roller mill depending on what material you need reduced.
The largest mill of this kind is presently the LM 63.4, which as a capacity for 840 t/h of ccment raw material at 15 % residue on 90 11m aperture size and which h as an installed power of up to 6000 kW. Smaller mills can he alrcady found in mineral processing as well for grinding of phosphate,
The roller mill minimizes such costs by precisely reducing feed materials with an average particle size up to 3 4 inch to a uniform average size typically between 100 and 2,000 microns. The roller mills ability to reduce materials to a uniform particle size provides more control of product characteristics and minimizes waste, as shown in Figure 1.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.
