SOLUTION

According to their processing capacity, dolomite grinding mill can be divided into three types: coarse grinding, fine grinding, and ultrafine grinding. Coarse grinding is suitable for soft and hard ores with compressive strength not exceeding 320MPa in medium and fine crushing, while fine grinding and ultrafine grinding are suitable for higher precision processing requirements. The VPM series ultrafine vertical grinding machine produced by our company can grind dolomite to a fineness of 325-3000 mesh or even higher. It has the characteristics of high efficiency, energy saving, and environmental protection, and the finished product has a high fineness, reaching D97 ≤ 5 μ m.

1. Process flow of dolomite grinding mill factory

The process flow of dolomite grinding mill mainly includes the following steps：

Crushing: Large chunks of dolomite are first crushed into small particles using jaw crushers or cone crushers, typically ranging in size from 15mm to 50mm.

Lifting and feeding: The crushed material is fed into the storage bin through a bucket elevator, and then evenly fed into the grinding chamber of the powder mill by a vibrating feeder.

Grinding: In the grinding chamber, the material disperses towards the periphery of the circle under the action of centrifugal force and falls into the raceway of the grinding ring, where it is impacted, rolled, and ground by the ring rollers. After processing through multiple layers of raceway, it becomes powder.

Grading and collection: The high-pressure fan draws external air into the machine and brings the crushed material into the powder selection machine. The rotating impeller inside the powder selector causes coarse materials to fall back and grind again, while fine powders that meet the requirements enter the cyclone powder collector with the airflow and are discharged as finished products through the discharge valve at the bottom.

2. Equipment configuration of dolomite grinding mill factory

A complete dolomite grinding production line usually includes the following equipment:

Crusher: such as jaw crusher, cone crusher, etc., used to crush large pieces of dolomite into particle size suitable for grinding machine.

Elevator: such as bucket elevator, used to feed crushed materials into the storage bin.

Grinding machine: such as HGM Ultra-fine Grinding Mill、Vertical Roller Mill、MTM Dolomite Grinding Mill、YGM Raymond Grinding Mill Wait, used to grind dolomite to the desired fineness.

Classification system: such as powder selection machine, classifier, etc., used to separate materials of different fineness.

Conveyor system: such as LS series screw conveyor, Belt Conveyor, etc., used to deliver finished powder to the finished material bin.

3. Application Fields

Dolomite powder is widely used in the following fields:

Construction industry: used for producing building materials such as cement, mortar, putty powder, etc.

Ceramic and glass industry: used as raw materials for the production of ceramics, glass and other products.

Chemical industry: used for the production of chemical products such as calcium magnesium phosphate fertilizer and magnesium sulfate.

Agriculture and Environmental Protection: Used for producing agricultural products such as fertilizers, pesticides, and environmentally friendly materials.

Metallurgical industry: used as a slagging agent in steelmaking.

Summarize

The dolomite grinding mill is an important part of dolomite processing, and its equipment configuration and process flow directly affect the quality and output of dolomite powder. Welcome to contact VEST and let us help you choose the appropriate equipment.
