Ultra Fine Vertical Roller Mill Plant

Introduction of ultra fine vertical roller mill plant

Raw materials: stone with Moh’s hardness less than 9.3 and humidity less than 6%
Capacity: 0.5-45 t/h Max feeding
size: 20 mm
Application: It can be widely applied to process large-scale ultra fine powder, encompassing calcite, marble, limestone, talcum, kaolin, dolomite, gypsum, feldspar and other non-metallic minerals.
Structure:It is mainly composed of bucket elevator, hopper, main unit, cyclone powder collector, dust cleaner, muffler, blower, sound proof room and so on.

Working principle of ultra fine vertical roller mill plant

The grinding disc is driving by motor through reducer. The material falls to grinding disc from the feed opening. The materials are driven to the edge of disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle take the fine powder to high efficiency classifier.The qualified powder are taken by the air to the powder collector to be collected, while the unqualified powder are sent back for regrinding.

Advantages of ultra fine vertical roller mill plant

1. Strong product diversity. CLUM series ultra fine powder vertical roller mill is equipped with a turbo air classifier, which can produce a large range of product sizes.

2. Use optimized production line process design, CLUM series ultra fine vertical roller mill consumption is lower than vertical mill consumption of the same type.

3. After classification, the ultra fine powder produced by the main unit is characterized by a narrow particle size distribution, high profit margins and added value to produce finished powder products, and good single particle shape. Because of the diversified finished product and strong competitiveness, it has the widely available applications, such as artificial stone, plastic master batch, PVC pipe, wire and cable, diapers, non-woven fabrics and other industries, with such advantages as good activation effects and low oil absorption.

4. After being improved, rollers, grinding table, diversion systems and internal circulation systems can greatly improve the grinding efficiency and improve output by 15%-30% compared to ball mills, etc.

5. With leading grinding equipment technology, the improved grinder can be operated at low vibration. Compared with Taiwan or domestic brands, CLUM series grinder has lower noise.

6. The whole system is fully closed-loop system, with small dust pollution, so the production environment is more clean and environmentally friendly.

7. In the main grinding mill, the main wear-resistant parts are all imported wear-resistant materials, which can increase the service life of the grinding machine and reduce maintenance costs.

8. The grinding process can fully automatically use computer to control the addition of grinding agent for powder processing, thus increasing product added value. The complete production line is fully under PLC control; flash real-time display and can perfectly link the machine control system of continuous modifier to achieve a high degree of artificial intelligence.
