the vertical roller mill process. Ball mill. Most existing ball mills designed for . can be increased significantly if a hot gas generator is included in the mill circuit and the . Further, the flow of hot drying gas through the mill is facilitated without an . Finish grinding operation results in very large savings in the specific energy.
The invention relates to a solid fired hot gas generator which comprises a plurality of solid burners for extending the regulating range, which form a multiple solid burner with an enlarged regulating range. A solid feed and a combustion air feed are assigned to each solid burner and with the aid of a dosing means a separate, dosed solid feed to each solid burner is guaranteed.
The system includes belt conveyors, mill feed bins, weight feeders, a vertical roller mill, recirculation bucket elevator, fabric filters, fans, pneumatic conveying system, hot gas generator, air gravity conveyors, a drag chain conveyor, hydraulic pump systems, blowers and other equipment.
The Millmaster system can be customised using our pre-designed modules which relate to the part of the grinding process that needs to be controlled such as vertical or ball mills, roller presses, separators, hot gas generators, water injectors and ventilation systems.
ing through the mill, independent of the amount of hot gas needed for drying. The ATOX coal mill has a water injection system to compensate for low water content in the raw coal, which allows increasing the amount of hot gas instead of recirculating gas at a level that would invalidate the .
