About Dolomite

Non-metallic mineral powder is an important part of modern new materials. With the development of modern industry and the rapid development of new materials, the non-metallic mineral powder industry continues to develop and improve. My country's non-metallic minerals are widely distributed and complete in varieties. With the development of high and new technology, non-metallic minerals have been widely used in the field of new materials and other traditional industries such as papermaking, plastics, rubber, coatings, building materials, and metallurgy.
 

Dolomite is a carbonate mineral, which is widely used after deep processing, and its fineness is different in different fields. Dolomite raw ore, dolomite sand 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-80 mesh, 80-120 mesh; Dolomite powder, dolomite superfine powder 140 meshes, 325 meshes, 600 mesh, 1000 meshes, 1600 meshes. Dolomite production equipment mainly uses mechanical crushing, including crushers, sand making machines and mills, and dolomite industrial grinding mills are the most used. It can produce dolomite powder with a particle size of 80-2500 mesh.

What mill is used to process dolomite?

The main ore grinding mills on the market now include Raymond mills, vertical mills, high-pressure suspension roller mills, and ultrafine grinding mills.
Which kind of mill is applicable, please refer to the following aspects:

1. The properties of the ore: The nature of the raw ore is closely related to the selection of equipment. The grinding equipment used for ores of different hardness is also different. After the nature of the raw ore is clearly understood, the equipment selection can help you to reduce Investment to buy more suitable equipment.

2. Feeding port size: Whether the size of the ore is compatible with the feed port size of the mill affects whether the front end crushing is required. This also indirectly affects the entire production cost.

3. Equipment production capacity: After clarifying the output you need, you must also know the production capacity of the equipment itself. Only the equipment that meets the requirements is the good equipment, so that the purchased machine can be economical and reasonable.

4. Finished product fineness: The processing fineness of the finished product directly affects the choice of equipment. The particle size of the finished product is different for different equipment. For example, the processing fineness of Raymond mill series is 80-600 mesh, vertical mill, ultra The fineness of the fine grinding machine is 325-3000 mesh. Generally, the higher the mesh, the more expensive the equipment is.

Dolomite powder can be used in the following industries:

In the metallurgical industry, dolomite with a raw ore particle size of 30-120 mm is an important raw material for the production of metallic magnesium. At the same time, dolomite is also one of the important raw materials for alkaline refractories. Its importance is second only to magnesite and is mainly used for smelting. Steel converter lining, open hearth furnace, electric furnace wall, and secondarily used in thermal equipment such as refining equipment outside the furnace and cement kiln.

In the chemical industry, dolomite can be processed to produce magnesium carbonate. At the same time, dolomite can also produce important chemical raw materials such as magnesium sulfate, magnesium oxide, and magnesium hydroxide after processing.

In the building materials' industry, the manufacture of magnesium oxychloride cement is another important use of dolomite. In addition, after calcining dolomite to produce caustic dolomite, it can also be processed into magnesium hydroxide cement and magnesium oxide sulfate cement. At the same time, the processing and utilization of dolomite also involves glass, ceramics and other fields.

With the development of modern science and technology, the processing and utilization of dolomite has penetrated into various fields of social development and has become a mineral resource of great economic value.
