Introduction Dolomite

The chemical composition of dolomite is CaMg (CO3) 2, which is a carbonate mineral, including iron dolomite and manganese dolomite. Its crystal structure is like calcite, often showing rhombohedron.

It will slowly bubble when encountering cold dilute hydrochloric acid. Some dolomite emits orange-red light under the irradiation of cathode rays. Dolomite is the main mineral component of dolomite and dolomite limestone.

It is mainly used as a flux for alkaline refractory materials and blast furnace iron making; production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; and ingredients for the production of glass and ceramics.

What Is Dolomite Powder Commonly Used For

Different fineness dolomite powder can be applied for various fields, specific fineness and usages are as follows:

1. Coarser than 200mesh: It can be used for a variety of feed additives (calcium content should be more than 55.6%, with no harmful ingredients);

2. 250-325mesh: Used for plastic, rubber factory, paint factory, waterproof material plant as raw materials and interior and exterior paint coatings (whiteness should be more than 85 degrees);

3. 350-400mesh: Used for the manufacture of pinch, the water pipes, chemical (whiteness should be above 93 degrees);

4. 400-600mesh: Can be used for toothpaste, soap (whiteness should be more than 94 degrees);

5. 800mesh: Used in rubber, plastics, cables, PVC (whiteness should be more than 94 degrees);

6. 1250mesh: Used for PVC, PE, paint, paper primer, topcoat paper (whiteness should be more than 95 degrees);

In addition, the dolomite powder has characteristics of high purity and high brightness, non-toxic, odorless, fine oil, low hardness, can be used as calcium supplements, the absorption rate can be up to 39%, right after the Calcium citrate malate, it is soluble in gastric acid, it has the most formulations and become the most widely-used calcium supplements; Also, because the dolomite is one kind of calcium carbonate, it is alkaline, often used to improve acidic soil.

Different Mills For Dolomite Processing With Different Product

For large-scale production lines with dolomite grinding powder below 400 mesh, Shanghai Zenith Mineral Company chooses to use vertical roller mills and MTW Trapezium roller mills; above 400 meshes, we choose to use XZM micro-powder ultrafine mills.

There are many kinds of dolomite milling equipment. According to the different requirements of different industries, different milling equipment can be selected. For different purposes of dolomite milling, Shanghai Zenith Mineral Company will recommend a suitable mill for you. Zenith has the opportunity to select milling equipment models and quotations based on your specific milling production needs to achieve your milling purposes.

Dolomite Mill Development Trend

First, the large-scale equipment. With the advancement of science and technology and the development of advanced technology, the advantages of large-scale production equipment are becoming more and more obvious. Coupled with the development of mechanical structure design and manufacturing technology, dolomite milling equipment is developing towards large-scale development.

Second, the structure is compact. With the development of high technology, the requirements for compact structure of dolomite milling equipment are becoming higher and higher. The compact structure can reduce the production cost of the equipment to a certain extent, reduce the occupied area and improve the working efficiency of the equipment.

Finally, the control system is automated. With the advancement of science and technology and the development of automatic control technology, today’s users have higher and higher requirements for equipment automation. A large-scale grinding equipment only needs one operator on-site care, which greatly reduces the labor intensity of labor. , But also to ensure the normal flow of operations. The realization of automation can also ensure the accuracy of the entire production process, thereby improving product quality.
