Brief Introduction of Ultrafine Vertical Mill

CLUM ultrafine vertical mill is a new type of ultra-fine grinding equipment integrating powder grinding, grading, conveying, secondary powder selection, and finished product packaging.

It can be widely used in large-scale ultra-fine dry powder processing of non-metallic minerals such as calcite, marble, limestone, dolomite, barite, talc, kaolin, dolomite, wollastonite, gypsum, feldspar, pyrophyllite, etc.

Applications of Ultrafine Vertical Mill


CLUM ultrafine vertical mills can be widely used in chemical, metallurgy, non-metallic minerals, and other industries, especially in the field of ultra-fine grinding of white non-metallic minerals.





It has excellent performance and can be used for papermaking, coatings, plastics, rubber, PVC, printing ink, and other industries to provide high-quality fillers and additives.


Structure & Composition of Ultrafine Vertical Mill

ultrafine vertical mill

Working principle:

The grinding disc is driving by a motor through the reducer.

The material falls to the grinding disc from the feed opening.

The materials are driven to the edge of the disc by centrifugal force and crushed into fine powders by rollers.

Then, the hot air from the nozzle takes the fine powder to the high-efficiency classifier.

The qualified powder is taken by the air to the powder collector to be collected, while the unqualified powder is sent back for regrinding.

Advantages of CLUM vertical mill production line

CLUM ultrafine vertical mill production line

Highly automated, good comprehensive benefits

The whole production line is highly automated, with high grinding efficiency, more stable operation, reduced maintenance intensity and production costs, high-quality finished products, and good comprehensive benefits.

24-hour continuous production without stopping

The grinding roller bearings and reducer of the main machine are all lubricated with thin oil, which can be used for 24-hour continuous production without stopping. The lubrication system is stable and reliable, and the maintenance is simple.

Low energy consumption for grinding

The grinding method of directly crushing the ground material by the grinding roller on the grinding disc reduces energy consumption. The grinding rollers and discs are not in direct contact during work, which can effectively improve the service life of the grinding rollers and liners and save production costs.

Special grinding curve, high quality finished powder

CLUM series ultra-fine vertical mills are equipped with specially designed roller sleeves and liner grinding curves. When processing ultra-fine powder, it is easier to form a material layer than ordinary vertical mills, reducing the residence time of materials in the mill, reducing repeated grinding, easy to detect and control product particle size and chemical composition, and easy to stabilize product quality. At the same time, the grinding roller and the grinding disc are not in direct contact, the iron content in the product is very small, and the mechanical wear iron contained in it is easy to remove, effectively ensuring the whiteness and purity of the finished product.

Intelligent control

CLUM series superfine vertical mill adopts PLC intelligent control internally, and externally adopts touch screen to display and adjust system parameters in real time. Modular interfaces are reserved, with strong scalability, which can quickly realize the connection of the front-end grinding aid adding system, the back-end powder modification system and the packaging system to ensure the automatic control of the whole process.

High environmental standards

The equipment runs stably and has little vibration, so the noise is low. The system is sealed as a whole and works under negative pressure, no dust spills, the environment is clean, and the emission standards far exceed international standards.

1. What are the design advantages of an ultrafine vertical mill?

① The CLUM vertical roller mill integrates crushing, grinding, grading, drying, and conveying into one.
② The system configuration is scientific and reasonable, the equipment layout is compact, the floor space is small, and the sealing performance is superior.
③ The oxygen content in the mill is low, the explosion suppression performance is superior, and the grinding process is safe and controllable.
④ The pulse dust collector can achieve 99.99% dust collection, creating a safe and dust-free environment-friendly workshop.

2. How to improve vertical roller mill milling efficiency?

The mill structure, scraper, hydraulic system, material, and pressure difference will all affect the grinding efficiency of the vertical mill.
The hardness, composition, viscosity, moisture, and particle size of the grinding material will all affect the output, so the appropriate grinding machine should be selected according to the nature of the grinding material.
When grinding, the feed should be uniform and stable, and the classification efficiency should be controlled reasonably. Regular inspection and maintenance of wearing parts, hydraulic systems, etc.
