Vertical cement mill

Capacity: 30-250 t/h

Power: 25-30 KWh/t

Specific surface area: 330-380m²/Kg 


Process introduction

The GRMK vertical cement mill of CHAENG adopts a new generation of cement grinding technology, which integrates grinding, drying and powder selecting functions. It can save 30% of power per ton compared with traditional ball mill. At the same time, it has many advantages, such as less auxiliary equipment, multiple functions, small occupied area and little dust pollution. It is widely used in clinker grinding production of cement plant and slag grinding plant.

CHAENG can provide various types of vertical cement mills with productivity of 50-250t/h. The biggest advantage of CHAENG is to have a large casting base and large machining workshops, which greatly shortens the delivery cycle of cement vertical mill.

GRMK vertical cement mill has the advantages of compact structure and small volume. It mainly includes high efficiency separator, grinding rollers, grinding table, hydraulic loading device of grinding roller, hydraulic lubrication system, reducer, motor, and electrical components.

1. Separator is an efficient and energy-saving powder selection device.
2. Grinding roller is used to grind and crush materials.
3. The grinding table is fixed on the output shaft of the reducer. It is the place where the grinding rollers grind materials.
4. The hydraulic loading device is a component that provides grinding pressure for the roller. And it provides sufficient pressure to crush the materials.
