Performance Advantage

Performance Advantage of
Calcium Carbonate Ultrafine Vertical Mill

Energy efficient

In the case of the same fineness of the finished product and the same motor power, the output is more than twice that of jet mill, stirring mill, and ball mill.

High safety and reliability

Because there are no rolling bearings and no screws in the grinding cavity, there is no problem that the bearings and their seals are easily damaged, and there is no problem that the screws are easy to loosen and damage the machine.

Easy to maintain

The grinding roller can be turned out of the machine with a hydraulic device, the replacement of the roller sleeve liner and the grinding machine have a large maintenance space, and the maintenance operation is very convenient.

Long service life of

wearing parts

The grinding roller and grinding ring are forged with special materials, which greatly improves the utilization. Generally, it can reach more than one year, and the service life can reach 2-5 years when processing calcium carbonate and calcite.

Environmental protection

(1) The whole system of CLUM ultrafine vertical mill has low vibration and low noise.
(2) The system is sealed as a whole, runs under full negative pressure, no dust spills, and basically a dust-free workshop can be realized.
(3) The pulse dust collector is used to capture dust, and the muffler is used to reduce noise, which is environmentally friendly and clean.

Stable product quality

(1) The material stays in the mill for a short time, it is easy to detect the particle size distribution and composition of the product, and the product quality is stable.
(2) The product has uniform particle shape, narrow particle size distribution, good fluidity, and strong product adaptability.

Structure of Calcium Carbonate Ultrafine Vertical Mill

Calcium Carbonate Ultrafine Vertical Mill is mainly composed of electric motor, reducer, grinding wheel device, grinding disc device, pressurizing device, powder separator, feeding device, oil station, main engine, electronic control system and other parts.

structure of ultrafine vertical mill

Grinding wheel device: the main part of the material to be rolled, without power output, and passively running due to the friction force in contact with the material.

Grinding disc device: the grinding area of ​​the material, connected to the reducer, rotates by itself.

Pressure device: control the gap between the grinding wheel and the grinding disc to ensure the pressure of the grinding wheel during the grinding process.

Powder separator: The multi-head powder separator structure uses the principle of rotating centrifugal force to realize the fine powder screening and filtration in continuous production. It is a highly efficient and energy-saving powder separator.

Working Principle of Ultrafine Vertical Mill

The main engine motor drives the milling disc to rotate through the reducer, while the air flow produced by the high-pressure fan enters the main engine from the tuyere.

The material is fed into the main machine of the vertical roller mill by the feeding screw and falls into the center of the grinding pan. Under the action of the centrifuge, the material is scattered from the center of the grinding pan to the surroundings.

When passing through the roller table area on the grinding pan, the bulk material is directly crushed by the pressure of the roller. After the small particles are compressed, they can be further pulverized until they become powder.

The powdered material continues to move to the edge of the grinding pan until it is taken away by the strong airflow from the air inlet.

When the materials in the airflow pass through the upper powder separator, under the action of the centrifugal force generated by the high-speed rotating impeller, the coarse particles fall into the grinding disc for grinding again, and the qualified powder passes through the powder separator system with the airflow and is collected by the dust collector, which is the finished product.
