Bentonite is a clay rock primarily composed of montmorillonite, a layered hydrous aluminum silicate mineral containing small amounts of alkali and alkaline earth metals The chemical composition of bentonite is stable, and due to its unique properties, such as swelling, adhesion, adsorption, catalytic activity, thixotropy, suspension, and cation exchange capacity, it is widely used in various industrial fields and is often referred to as "universal clay."
Generally white or light yellow, but can also appear in light gray, light green, brick red, and gray-black due to variations in iron content.
Density: 2-3 g/cm³
Hardness: 1-2
It has a waxy, earthy, or greasy luster; bentonite can be loose like soil or dense and hard.
It can absorb water equal to 8 to 15 times its own volume
It can disperse in an aqueous medium to form a colloidal suspension.
It has strong cation exchange capacity and adsorption ability.
Volume expansion can be several times, up to 30 times.
It has plasticity and binding ability when mixed with fine debris such as water,mud, or sand.
It can reach up to 800 m²/g
The chemical composition is relatively complex, primarily consisting of silicon, aluminum, sodium, and magnesium. It comes in various colors, has strong adsorption capacity and stability, and can maintain its adsorption properties in high-temperature and acidic or alkaline environments. It is easily soluble in water and exhibits solubility and electrolytic properties.
The chemical composition is relatively simple, primarily consisting of silicon, aluminum, and calcium. It appears grayish-white and is insoluble in water. It has oily and organic properties, but its adsorption capacity and stability are relatively weak. It is prone to decomposition in high-temperature and acidic or alkaline environments, leading to a loss of adsorption ability.
Odorless, tasteless, and non-toxic, it has strong adsorption properties and can adsorb colored substances and organic materials. It is prone to moisture absorption in the air, and prolonged storage can reduce its adsorption performance.
It is a white or grayish-white clay primarily composed of montmorillonite, sodium feldspar, and quartz, and is a type of bentonite. It is prone to moisture absorption in the air, and prolonged storage can reduce its adsorption performance.
It has good thickening, thixotropic, suspension stability, high-temperature stability, lubricating, film-forming, water resistance, and chemical stability properties, making it of significant value in the coatings industry.

Used for treating industrial wastewater, purifying swimming pool water, and processing waste from the food industry Bleaching clay and sodium bentonite
Dye for carbonless copy paper, pigment filler Bleaching clay, sodium and magnesium-based bentonite
Plasticizer for ceramic raw materials (to improve the compressive strength of ceramic bodies), used in the production of glazes and enamels Various types of bentonite
Using sodium bentonite as an example, dry processing is generally used to treat bentonite with good quality. This method involves low-temperature drying or natural sun-drying of the raw ore, crushing it to an appropriate particle size, and then using grinding equipment to process it into products with a particle size of 100-325 mesh.
As a provider of comprehensive solutions for grinding equipment, Liming Heavy Industry is committed to offering customers efficient, energy-saving, and environmentally friendly grinding equipment and services.
With nearly forty years of experience in mill manufacturing, Liming Heavy Industry has introduced the MTW European trapezium grinding mill and LM vertical roller mill in the field of bentonite grinding. These machines are specially treated and optimized to address the characteristics of bentonite, such as high silicon-aluminum content, high hardness, high moisture, and tendency to agglomerate. The bentonite powder produced has high whiteness and purity, good dispersibility, and is less prone to settling The quality of the products is more reliable, and the degree of automation in production is high. The equipment operates stably and efficiently, meeting the demands for large-scale, green production.
LM vertical roller mill is a product developed by Liming Heavy Industry that combines modern grinding technology and has independent intellectual property rights. This equipment is widely used in industries such as new energy, new materials, non-ferrous metals, energy chemistry, resource recycling, as well as in large metal and non-metal mines.
Using a new type of grinding device with an automated electrical control system
Integrates drying, grinding, classification, and conveying into one
