Raymond Mill Classifier

Features and Advantages of Raymond Mill Classifiers

Precise Classification: Dynamic sorting is realized by high-speed centrifugal impellers with high separation efficiency, ensuring uniform and stable product fineness.

Flexible Control: The product fineness can be quickly adjusted by changing the impeller speed via frequency converter without replacing parts, achieving accurate and flexible control over powder fineness.

Energy Saving & Capacity Increase: It forms a closed circulation where qualified fine powder is separated in time and coarse powder returns for regrinding, effectively preventing over-grinding. It reduces energy consumption while improving the output and powder quality of the Raymond mill.

Clean & Eco-friendly: The whole system operates under negative pressure. Dust is effectively confined inside the system without leakage, keeping a clean working environment and meeting environmental protection requirements.

Automatic Control: Compact structure and high integration. It is easy to realize automatic control with remote adjustment and on-line monitoring, featuring stable, reliable operation and convenient maintenance.

Maintenance Tips for Raymond Mill Classifiers

Cleaning and Inspection: Shut down the machine regularly to thoroughly clean adhered fine powder and material buildup on impeller blades, air guide plates and inner cavity walls to guarantee uniform airflow field distribution. Impeller wear and dynamic balance must be inspected after each cleaning. Repair and calibration shall be carried out immediately if blades are damaged, deformed or dynamic balance exceeds tolerance.

Lubrication and Sealing: Focus on lubrication and sealing of the main shaft bearing. Fill high-temperature high-speed grease periodically and check the effectiveness of sealing components.

Precision Calibration: Calibrate frequency converter parameters and speed feedback devices regularly to ensure accurate control of classification rotating speed.
