Dolomite has been used for many years in the refractory industry due to its chemical composition and durability. It is a mineral composed of magnesium and calcium carbonate that can exist in several different forms. Dolomite powders are widely used in many industrial applications such as filters, absorbents, and catalysts. The purpose of this paper is to provide an in-depth look at the pointwise refractory uses of dolomite powder manufactured by Vasundhara Micron.

Dolomite is a sedimentary rock that is composed of calcium and magnesium carbonates. It has a wide range of applications such as in cement, glass, bricks, fertilizers, and other industries. Processing dolomite is a crucial part of maximizing its value. Therefore, the process of extracting and powdering the dolomite ore is a vital step for dolomite powder manufacturers such as Vasundhara Micron to provide quality dolomite powder for its customers.

Understanding Dolomite Processing

Dolomite processing is a complex process that involves the usage of different techniques and machines. The process begins with the extraction of dolomite ore from the ground. The ore is then crushed and passed through a separator. This is to separate the ore from any unwanted substances or impurities. The crushed ore is then passed through a mill which further grinds the ore into a fine powder. The powder is then passed through another stage of screening to get the desired size of the powder. Finally, the powder is dried and packed.

The Characteristics of Dolomite Powder

A. Chemical Composition and Properties

Dolomite powder is a combination of magnesium and calcium carbonate. Its chemical formula is CaMg(CO3) 2 and its chemical composition consists of 40-50 percent magnesium carbonate, 47-58 percent calcium carbonate, and 1-6 percent impurities. It is an insoluble mineral and its hardness levels range from 4-5 on the Mohs scale. It has a crystalline structure and its refractive index is between 1.41-1.46.

B. Powders and Particles

Dolomite powders are typically ground to target particle size distributions, ranging from 100 mesh to 500 mesh. The ground powders are very fine in texture, powdery, and lightweight. The particles are highly porous, making them ideal for use in industrial applications. They are engineered to have a uniform texture that is easy to use and disperse.

Benefits of Powdering Dolomite

Powdering of dolomite is something that is beneficial for all users. Powdering helps in reducing wear and tear on the machinery due to greater surface area of the particles, which prevents wear and tear. Additionally, powdering dolomite also helps in increasing the solubility of the dolomite components. This makes it easier to mix and blend with other substances. Also, its high surface area makes it perfect for absorbing liquids, thus providing its various applications in industries.

Refractory Applications of Dolomite Powder

A. Resistant to High Heat

One of the main applications of dolomite powder is its ability to withstand high heat. It is a highly refractory material, meaning that it can withstand temperatures of up to 2000°C without breaking down or becoming soft. This makes it an ideal material to use in applications such as kilns, furnaces, and fireplaces.

B. Absorbs Moisture

Dolomite powder also has the ability to absorb moisture, which makes it an effective material to use in the manufacture of refractory mortar. The powder’s high porosity allows it to absorb moisture, hence, making it a more effective material in applications such as fireproofing and sealing.

C. Resistant to Corrosion

Dolomite powder also has the ability to resist corrosion from most acids and alkalis. It is inert to most chemicals and does not dissolve or react with acids or alkalis. This makes it an ideal material for use in refractory applications such as heaters and heat exchangers.
