It can grind and process quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, iron ore, copper ore, phosphate rock, iron oxide red, zircon sand, slag, water slag Clinker, activated carbon, dolomite, granite, garnet and other minerals and minerals. Therefore, the processing of limestone has unique performance and advantages, and has achieved outstanding results and effects in grinding sites around the world, creating value and benefits for our customers.
The high-efficient and energy-saving limestone mill is a new type of mill equipment, which can be used not only in the industry of limestone powder, but also in the industry of calcium carbonate powder processing, calcite powder processing, talcum powder processing, gypsum powder processing and other mineral powder industries. High efficiency, high fineness and high passing rate are another technical feature of this equipment.

Technical Data

Re:The data based on Mohs'hardness 3-4 material

Limestone Bond Index≤13kwh/t

Working principle

The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc 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 disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing water are dried in the Contact process with hot gas to meet the required product moisture.

Materials that can be processed by HVM vertical mill: ferrite, slag, slag, cement, diamond, iron ore, chrome ore, manganese ore, gold mine, copper mine, aluminum ore, lead zinc ore, tantalum niobium ore, polymetallic ore, nickel ore, bauxite, silicon carbide, titanium dioxide, talc, bentonite, calcite, kaolin, graphite, mica, wollastonite, feldspar, dolomite, pyrophyllite, quartz sand, fluorite, limestone, organic silicon, limestone Shale, volcanic ash, coal, etc.

Advantage
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 disc structure design, and the roller adopts hydraulic automatic pressure device, resulting in a larger grinding area and high grinding efficiency. The finished product has uniform particle size distribution, good quality, 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 with the grinding disc, resulting in low vibration and low noise; Equipped with automatic slag removal function, ensuring the safe operation of the equipment.

4. High drying capacity
Materials can be transported using hot air, and the inlet temperature can be controlled based on the moisture content of the material. Materials with a moisture content of up to 15% entering the mill can be dried, and the moisture content of the mill can be less than 1%.

5. High degree of automation
Adopting an automatic control system, it can achieve remote control, chain protection, reliable operation, and easy operation.

6. Easy maintenance and low operating costs
The grinding roller bearing adopts forced thin oil lubrication and is equipped with a hydraulic roller flipping device. During maintenance, the grinding roller can be flipped out of the machine by the hydraulic device, which has a large maintenance space, convenient maintenance, and low operating cost.

7. High efficiency environmental protection
The entire production line adopts a negative pressure closed circulation system and is collected by an efficient pulse dust collector, without dust leakage, meeting the latest national environmental protection requirements.

8. Integrated and comprehensive solution
A professional technical service team provides users with design, supply, and installation turnkey services, integrated and comprehensive solutions, which saves time and effort.
