Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.

Coal vertical roller mill adopts advanced technology, finished product has highefficiency distribution and excellent combustion performance. 4. Floor space is smallest. Due to its structure features, coal vertical roller mill, compared with the same specifiions, can reduce floor space and floor usecost greatly than ball mill.

Vertical coal mill uses 20% to 40% less electricity than a traditional airswept ball mill for the same amount of grinding task. Drying Performance. Airswept milling method allows our mill to handle coals of up to 10% moisture content via varying its air flow rate and temperature.

The vertical coal mill consists of many parts, among which the vertical mill grinding table and the grinding roller play a crucial role in the material grinding. The primary function of the table is to support the material bed and transfer the force generated by the roller to the lower speed reducer, and also transmits the torque of the speed ...

Pulverized Coal Injection Project, coal mill. Blast furnace PCI /rotary kiln PCI/vertical kiln PCI have been the main method for lime stone roasting, pellet roasting, coking, iron increasing, reduced cost, improve high efficiency smelting,and promote blast furnace running smoothly, also is the main method for technical progress of blast furnace iron making.

Ball mill is mainly used for grinding in mining (metallic minerals and nonmetallic minerals), cement, refractories, chemical, power plant, aluminum,building material, glass, ceramic, steel slag and fly ash, ect. It follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel .

The vertical ball mill has stable performance, supports dry and wet grinding, and has unique performance for coarse and thickened materials. Vertical ball mill can be widely used for dispersion and grinding of solid or powder materials in paint, medicine, building materials, chemical industry and other industries.
