Cast basalt aggregate

Basalt is a volcanic rock that is formed from the rapid cooling of lava. It is known for its high strength, durability, and thermal resistance, making it suitable for various applications in industries like construction, transportation, and manufacturing.

In the production of cast basalt products, such as pipes, tiles, and linings, the basalt aggregate is mixed with a binding agent, usually epoxy resin or cementitious material. The mixture is then cast into a desired shape and cured to form a solid product.

Cast basalt products, reinforced with the aggregate, exhibit excellent resistance to abrasion, corrosion, and impact. They are commonly used in applications where high wear and chemical resistance are required, such as in lining chutes, hoppers, pipelines, and tanks.

Overall, cast basalt aggregate plays a crucial role in the manufacturing of cast basalt products, providing them with the desirable properties that make them suitable for heavy-duty industrial applications.

When it comes to basalt, we generally only know that it is often used to make stone aggregates, and it is an ideal aggregate raw material. But in fact, basalt can also be made into fine powder and used as a mixing material for cement. The effect is ideal, and it can also save coal consumption, which has good economic and social benefits. Guilin Hongcheng basalt vertical mill will introduce you.

Basalt is a good raw material for producing cast stone. Cast stone is a material made of basalt after melting, casting, crystallization, and annealing. It is harder and more wear-resistant than alloy steel, and stronger than lead and .

Cast basalt sand

Basalt is a volcanic rock, a durable and hard stone. Basalt sand and stone are available in every degree.

Basalt is a type of volcanic rock formed by the cooling and solidification of molten lava that come out of the cracks of the earth's crust.

Basalts are generally dark black in color. Basalt is a hard and hard stone and it is used in ballast, gravel and sandblasting industry. It is used in basalt sandblasting industry that does not contain free silica. Basalt is a rock with a hardness of 6.5 mohs and a density of 2.77 gr / cm3, which contains 45-50% SiO2. Basalt sand is used in scraper in the range of 0.5-1.6mm, 1.0-2.0mm and 1.5-2.7mm.

Cast basalt powder

Cast basalt powder

The Basalt Fiber Power is also named as The Basalt Grated Fiber;

Cast Basalt Powder, also known as basalt powder or greenstone powder, is primarily derived from high-quality raw materials, notably crystallized cast basalt. Through crushing and ball milling, it forms a fine, light gray powder renowned for its excellent acid and alkali resistance. The main components are silicon dioxide and aluminum oxide, with trace amounts of other oxides, iron oxide, calcium oxide, titanium dioxide, etc. Cast basalt powder can be formulated into acid-resistant (alkali) mortar, surpassing the corrosion resistance of acid-resistant cement by over ten times. Ranging from 120 mesh to 300 mesh, it showcases superior performance.

How to Configure Cast Basalt Powder

Scientific blending is crucial when mixing cast basalt powder with other materials. For formulating acid-resistant refractory castables, common materials and their acid resistance (measured by weight, %) are: cast basalt 98%, silica stone greater than 97%, clay clinker 92%–97%, talc 92%–96%, and andesite greater than 94%. The choice depends on usage conditions. It's essential to note that the use of silica requires caution due to crystalline changes during heating, causing volume variations (expansion). Hence, waste silica brick materials are used to replace some silica raw materials as aggregates. The powder for this castable mainly includes silica powder, cast basalt powder, porcelain powder, high-silica clay clinker powder, with cast basalt powder being a prevalent acid-resistant powder.


High Wear Resistance: The wear resistance of cast basalt aggregate and powder surpasses ordinary steel and even manganese steel.

Corrosion Resistance: Materials composed of cast basalt aggregates, sands, and powder exhibit robust corrosion resistance.

Uniform Particle Size: Cast basalt powder offers a uniform and fine texture, facilitating consistent mixing for production needs.

Low Water Absorption: Cast basalt aggregates, sands, and powder have an almost zero water absorption rate.

Field of Application

Cast basalt wear-resistant aggregates are widely used in the manufacture of various wear-resistant materials, such as wear-resistant floors, linings for wear-resistant pipes, wear-resistant coatings, etc. In the industrial field, they are employed to enhance the wear resistance and service life of materials.

The chopped basalt fiber usually chopped to 400mesh,the diameter of the fiber is between 9-18μm, the length is between 30-50μm. The highest temperature could reach to 1000℃.

The wear resistance performance of the basalt fiber powder is very nice, it is widely used in friction material, such as the brake plate, the polishing wheels, the grinding wheel, the friction plate, the wear resistant pipe, the wear resistant bearing etc.

The basalt fiber powder(the basalt fiber) is also the comprehensive optimal substitute product of the asbestos, the corrosion resistance, the wear resistance, the high temperature resistance and low temperature resistance properties are higher than asbestos, it is low poison, environmental and it is not harm to people, it do not make any pollution in production and using process.
