Grinding roller mill Introduction

Grinding roller mill is widely used in cement industry raw material, clinker preparation, grinding slag, ore, industrial silicon, calcium carbide slag, coal gangue and coal chemical, power plant desulfurization, coal powder preparation and other fields. Energy-saving grinding equipment..

Grinding roller mill working principle

The working principle of the Grinding roller mill: The motor drives the grinding disc to rotate through the reducer, and the material falls from the feeding port to the center of the grinding disc through the lock air feeder, and the hot air enters the grinding chamber from the air inlet. As the grinding disc rotates, the material moves to the edge of the grinding disc under the action of centrifugal force. When it passes through the annular groove on the grinding disc, it is crushed by the grinding roller and crushed. After the crushing, the material is brought up by the high-speed airflow of the wind ring at the edge of the grinding disc, and the large particles fall directly to the grinding disc. When re-grinding, when the material in the airflow passes through the upper separator, the coarse powder falls from the cone to the grinding disc and re-grinds under the action of the rotating rotor. The qualified fine powder is ground together with the airflow and collected by the dust collecting device, which is the product. The moisture-containing material is dried during the contact with the hot gas stream, and the temperature of the hot air can be adjusted to meet the requirements of different humidity materials to achieve the desired product moisture. By adjusting the separator, the thickness required for different products can be achieved..
