Vertical Cement Mill

Capacity: 30-250 t/h

Power: 25-30 KWh/t

Specific surface area: 330-380m²/Kg 


Application: Clinker grinding in cement plants and grinding stations

Process introduction

The GRMK cement vertical roller 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 for clinker grinding in cement plant.

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 vrm 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.

Remarks: vertical mill type spectrum benchmark:

(1) Medium Friction MFk=0.9-1.0;

(2) Cement Blaine Test: 3300-3800cm²/g, the bigger of the Blaine test, output will decrease accordingly;

(3) Final cement moisture 0.5-1.0%;

(4) The specific installed power and technical parameters can be adjusted appropriately according to the actual material property and owner's requirement.
