Product features: CLUM mill integrates the functions of grinding, classifying, conveying, secondary classifying, and packing progress into one machine. Its powder fineness can reach 400- 3000 mesh.
Available materialsGrinding roller: Main component for crushing and grinding materials. No power input when the grinding plate turn rotary, the rollers are rotated passively by friction force after touch the materials.
Grinding Plate: The area for grinding process, to be rotated and driven by reduction gear.
Pressure- applying device: Control the grinding roller and plate gap, keep the roller pressure.
Classifier: Multi-rotor classifier, utilize the rotated centrifugal force to separate the fine powder during the continuous process. It is a highly-efficient and energy-saving powder separating device.
While passing across the track in the grinding plate, large blocks of materials are crushed and grinded directly by the grinding roller.
The fine powder continue to move towards the fringe of the grinding plate until they are taken away by strong air flow at the air ring.
- 1. The coarse granular and impurities will fall into the lower grinding chamber, and be discharged out by the scraping plate.
- 2. High-precision multi-rotor classifier adopts frequency control, adjustable rotor speed, produces various particle size.
- 3. Adjusting the hydraulic system pressure to change the roller pressure, fit for materials with different hardness.
- 4. Electronic caging device makes sure the safety gap between roller and plate, effectively avoide the heavy vibration due to lack feeding.
Applications
CLUM series ultrafine powder vertical roller mill can be widely applied in the industries of chemicals, metallurgy, non-metallic ores etc. In particular, it is outstanding in processing white superfine non-metallic ore powders, providing superior quality fllers and additives for paper making, coating materials, plastics, rubber, PVC, printing ink etc.
Advantages
Low operation cost.
Use the special anti-wear alloy materials for grinding roller and plate liner. Long service time for wear parts, low maintenance.
The grinding curves of the roller shell and liner plate are uniquely designed, easy to form the stable material bed, low vibration, high product efficient.
It is 20% higher than other equivalent vertical mill in capacity, saving 40% powder consumption compared with ball mill.
High added value.
Adopting the multi-rotor classifier, the final particles size for D97 5-45 micron are attainable.
Equipped with the PLC frequency converter control system, the CLUM vertical roller mill can produce 2 micron (20- 70%) powder and adjust powder selection patterns according to clients' different requirements.
It has greatly increased the final powder added value and application areas due to the advantages of narrow particle size distribution, unit form particles shape and controlable 2 micron content.
Safe and reliable.
The pressure being applied to the grinding roller auto-controlled by the PLC/DSC enables the accurate control of grinding pressure and highly efficiency without manual operation.
The roller shell and grinding disc liner plate gap is dual protected by electronic and mechanical caging devices to avoid the heavy vibration and impact.
Reducer box and lubricating system are equipped multiple inspection and protection device.
Each roller has the independent lubricating cycle with double pumps.
The sufficient lubrication and cooling of the bearings for the grinding roller is ensured therefore no excess of lubricating oil in the bearing chamber and no leakage could occur.
Equipped with multiple intelligent protection devices the CLUM main unit can realize the continuous operation with stable, safe and high- efficient performance rather than stop running.
Environment friendly.
The roller and grinding disc do not touch each other directly, there does not have the metal impact noise in low vibration. Compared with ball mill the running noise is 20-25db lower which would not hurt human's health.
Hermetic seal ensures that the system operates under negative pressure. The final powder is conveyed to the final product silo without dust leakage . The environment is clean, meeting the national environmental protection requirements
Test Standard
- Material: Base on calcite
- Particle size distribution: Measured by micro laser diffraction particle size analyzer in British
