High Efficiency Bauxite Grinding Mill Dolomite Pulverizer Machine Vertical Mill Equipment
Description
Product description: Vertical mill, also known as roller mill, is widely used in large-scale material grinding and ultra-fine grinding processing in cement chemical, coal, electric power, and other industries. It is an ideal equipment for the grinding industry that integrates crushing, drying, grinding, grading, and transportation. When used in the preparation of pulverized coal, the fineness of the product can meet industry standards.
Capacity: Different materials have different processing capacities. For details, see the following technical parameter table
Suitable materials: Vertical roller mill mainly grinds raw meal, clinker, mineral powder, slag, granulated blast furnace slag, limestone, pulverized coal, coke powder, coal gangue, fly ash, volcanic ash, gypsum, calcite, pyrophyllite, clay, sand, bauxite, silica fume, etc.
Application industries: cement chemical industry, coal, electric power and other industries.

Re:The data based on Mohs'hardness 3-4 material
The product fineness can reach 10 um(1250 meshes)
working principle:
The motor drives the grinding plate to rotate through the reducer, and the material falls in the center of the grinding plate from the feed inlet. At the same time, hot air enters the grinding plate from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding plate and is crushed by the grinding roller as it passes through the circular groove on the grinding plate. The crushed material is picked up by the high-speed airflow at the wind ring at the edge of the grinding plate, and large particles directly fall onto the grinding plate for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding plate for re grinding, and the qualified fine powder exits the grinding along with the airflow, The product is collected in the powder collecting device. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.
Advantages & Characteristics
1. Low investment cost
It integrates crushing, grinding, drying, powder selection, and transportation, with a compact layout and can be arranged outdoors, greatly reducing investment costs.
2. High grinding efficiency and good product quality
Special roller and grinding plate structure design, and the roller adopts hydraulic automatic pressure device, resulting in larger grinding area and high grinding efficiency. The finished product has uniform particle size distribution, good quality powder, good fluidity, and high activity.
3. Reliable quality and stable operation
The transmission system adopts advanced planetary gear reducer, with strong bearing capacity and stable operation; The grinding roller is equipped with a hydraulic pressure system and a limit device to avoid direct contact between the grinding roller and the grinding plate, resulting in small vibration and low noise; It has the automatic slag removal function to ensure the safe operation of the equipment.
4. Large drying capacity
Hot air can be used to transport materials, and the air inlet temperature can be controlled according to the water content of the materials. Materials with a water content of up to 15% entering the mill can be dried, and the water content of the outgoing mill is less than 1%.
5. High degree of automation
Using an automatic control system, remote control, interlocking protection, reliable operation, and easy operation can be achieved.
6. Convenient maintenance and low operating cost
The grinding roller bearing adopts forced thin oil lubrication, and is equipped with a hydraulic roller turnover device. During maintenance, the grinding roller can be turned out of the machine by the hydraulic device, providing large maintenance space, convenient maintenance, and low operating cost.
7. Efficient and environmentally friendly
The entire production line adopts a negative pressure closed circulation system and adopts a high-efficiency pulse dust collector for collection, without dust spillage, meeting the latest national environmental protection requirements.
8. Integrated comprehensive solution
A professional technical service team provides users with turnkey services for design, supply, and installation, as well as integrated and comprehensive solutions, saving time and effort.
