CRRM1280 Raymond Mill Specifications
Composition and Structure
Grinding Roller
It integrates core functions such as grinding, fineness adjustment, efficiency enhancement, wear resistance, and uniformity. It grinds the material into powder by rotating extrusion, and the pressure can be adjusted to flexibly meet various fineness requirements.
Grinding Ring
It cooperates with the grinding roller to grind large pieces of material into fine powder at high speed. Its core function is to firmly support the grinding roller during operation and guide the grinding roller to roll along a stable trajectory.
Shovel
The main function is to scoop up the material entering the mill and send it between the grinding roller and the grinding ring for grinding. It is usually made of wear-resistant material to resist the wear of the abrasive.
Analyzer
It is used to control the fineness of the finished product. The particle size of the powder is controlled by adjusting the speed of the analyzer.
Working Principle
1. Coarse Crushing
Large pieces of raw materials are coarsely crushed into particles ≤30mm by the crusher for subsequent grinding.
2. Quantitative Delivery
The electromagnetic vibrating feeder quantitatively and continuously delivers the coarse crushed raw materials to the grinding area to ensure grinding stability and continuity.
3. Grinding Process
The grinding roller presses on the rotating grinding ring with centrifugal force to form a "rolling belt", and the raw materials are crushed into powder by double extrusion and shearing.
4. Grading & Collection
The powder enters the turbine classifier with the airflow, the coarse particles fall back to the grinding area, and the qualified fine powder enters the collection system.
