Product features


High grinding efficiency

Saving 40% -50% power consumption compared to ball mill. the grinding roller grinding table does not direct contact during the grinding process, so the noise of the whole system is low.

Low investment cost

It integrates crushing, drying, grinding, powder selection, and conveying into one, with a simple process flow and compact layout; Small footprint, can be arranged in the open air, low construction cost.

Stable product quality

The product has a narrow particle size distribution, uniform particle shape, and good fluidity. Grinding roller bearings are lubricated with forced thin oil, which longer bearing life.

The high degree of automation

Adopt a fully automatic control system, that can realize remote control, easy to operate.

Working principle

Working principle

The vertical rolling mill has two pairs of grinding rollers. Each pair of the roller is composed of two narrow rollers mounted on the same axis and can rotate at different speeds. The motor driving reducer makes the grinding plate rotate. The raw material is sent to the center of the rotating grinding plate by the locking air feeding equipment. Under the action of centrifugal force, the material moves to the surrounding area of the grinding plate and enters the grinding roller slide. Under the action of roller pressure, the material is crushed by extrusion, grinding, and shearing. At the same time, the ground material is flowed by hot air upward from the wind ring. The coarse granularity will be back to the mill to regrind and suspended material will be dried. Fine powder following hot air is taken to the classifier system. Qualified powder enters the powder collector with airflow as finished products. Unqualified powder falls to be regrinded with new feeding material together. This cycle is continuous to complete the whole grinding process.
