Technical Advantages
The unique curves on the roller and plate make grinding more efficient, creating a better material bed for higher output of quality products.
A compacting tool maintains fine grinding, while minimal mill vibration cuts energy waste. Quicker processing reduces over-grinding, lowering iron content for purer, whiter results.
A touch of additive boosts value without quality loss.
The CLUM mill uses multi-rotor classifiers to tailor powder fineness, avoiding waste. Its PLC system finely tunes grinding for consistent quality. With ultrafine grinding tech, it saves up to 50% energy, making it a cost-effective choice.
The mill features an advanced separator for a wide particle size range, with up to 70% 2μm powder, D97 from 4-45μm, and a surface area of 21000cm2/g.
It outputs primary powder at D97=8.5μm, and a secondary system captures 4-5μm particles, ensuring a high-value, well-shaped powder.
The mill’s grinding pressure is precisely managed by a PLC/DCS system for efficient, stable operation. Remote control is a breeze with the automatic system, and variable speed lets it handle tough materials.
Protection measures prevent roller damage, ensuring stable runs. The rollers have their own smart lube system to keep them cool and leak-free.
The grinding roller does not contact the grinding plate directly. Both the grinding roller and the lining plate are made of high-quality materials. Therefore, these parts enjoy long service life and high wear resistance.
The grinding roller can be turned out of the mill shell. This feature facilitates the inspection of the grinding roller and the replacement of the roller sleeve and lining plate, thus reducing downtime and labor costs.
The special structural design and operating principle of the mill ensure small vibration and low noise.
The whole equipment is well sealed and the system operates under negative pressure. Therefore, powder and dust are prevented from flowing out of the system. It is environmentally friendly and meets the national environmental protection requirements.

Composition of CLUM vertical roller mill production line
The CLUM ultra-fine vertical mill production line includes a primary powder making system (mainly raw material crushing, raw material transportation, ultra-fine grinding and classification, finished product collection, finished product transportation, finished product storage, and auxiliary equipment) and a secondary powder selection system (mainly It consists of multi-rotor ultra-fine powder separator, fan, pulse dust collector, elevator, discharge valve, screw conveyor and finished product tank).
Working Principle
The material shaken passes through the screw feeder and falls into the center of the grinding plate. The host drives the reducer to drive the centrifugal force generated by the rotation of the grinding plate, causing the material to move evenly around the grinding plate. When the material passes through the roller path area on the grinding disc, it is crushed by the grinding roller, and the large pieces of material are directly crushed, and the smaller particles are squeezed to form a material bed for inter-particle crushing.
After being crushed, the materials continue to move toward the edge of the grinding plate, and are taken to the powder separator for classification by the airflow entering from the air inlet. Under the action of the blades of the powder separator, the powder that does not meet the particle size requirements falls into the grinding disc and is ground again. The powder that reaches the standard passes through the powder separator and enters the pulse dust collector with the air flow for collection. The collected and discharged powder is the finished powder.
Impurities such as iron blocks mixed in the material are difficult to grind and have high gravity. When passing through the edge of the grinding disc, they cannot be carried away by the airflow and fall into the lower chamber of the mill. They are sent to the slag spit by the scraper and discharged from the outside of the main machine.
Operation process of CLUM vertical roller mill production line
The CLUM series ultra-fine vertical mill production line is a new type of ultra-fine grinding equipment that integrates grinding, grading, transportation, secondary powder selection, and finished product packaging. The product fineness can reach 400-3000 mesh.

Comparison between CLUM vertical mill and ball mill
Vertical mills and ball mills are both commonly used industrial grinding equipment, but they have certain differences in working principles, applicable materials, finished product fineness, production capacity, energy consumption, etc. So how do we choose the most suitable grinding equipment? The following is a simple comparison between vertical mills and ball mills to help you choose a more suitable grinding equipment.
The vertical grinding mill adopts the principle of “material bed grinding“. The material forms a material bed on the grinding disc. Through the action of roller pressure and centrifugal force, the material particles rub and collide with each other to be crushed
Main structural components: grinding disc, grinding roller, separator, dust collector
The discharge fineness of the vertical roller mill can reach 3000 mesh. Suitable for materials with medium hardness, brittleness and non-stickiness
- High grinding efficiency and low energy consumption; 2. Uniform product fineness and less over-crushing; 3. Less pollution and low operating costs
The finished powder has high whiteness and slightly worse sphericity than the ball mill
Efficient and flexible control of product categories, enabling conversion of different raw materials on one machine in a short time
VS
The ball mill adopts the principle of “media grinding“. The grinding chamber is filled with a certain number of steel balls or steel rods, and the materials are crushed under the impact and grinding action of the steel balls or steel rods
Main structural components: cylinder, lining plate, grinding ball, transmission device
The discharge fineness of the ball mill is generally between 20 and 200 mesh. Suitable for materials of various hardnesses, wider scope of application
