Composition and Structure: Attapulgite powder is primarily composed of magnesium and aluminum silicate, with water molecules occupying the interlayer spaces between the mineral layers. Its distinctive chain layered structure gives it excellent adsorption and absorption properties, making it highly effective in a wide range of applications.
Properties:
Adsorption: Attapulgite powder has a high surface area and porosity, allowing it to adsorb and trap molecules and particles from liquids and gases. This property makes it useful in applications such as filtration, purification, and adsorbent materials.
Absorption: Due to its unique structure, attapulgite powder can absorb large amounts of water and other liquids, forming stable gels or suspensions. This property makes it ideal for use in absorbent products, such as cat litter, industrial spill cleanup materials, and pharmaceutical formulations.
Rheological Properties: Attapulgite powder exhibits thixotropic behavior, meaning it becomes more fluid when agitated or sheared and returns to a gel-like state when left undisturbed. This property makes it valuable as a rheological additive in paints, coatings, drilling fluids, and other applications requiring controlled viscosity and flow behavior.
Stability: Attapulgite powder is chemically stable and resistant to high temperatures, acids, and alkalis, making it suitable for use in harsh environments and industrial processes.
Further reading:Applications:
Oil and Gas Industry: Attapulgite powder is commonly used in drilling muds and fluids for oil and gas exploration and production. Its rheological properties help control viscosity and suspension of solids, prevent fluid loss, and stabilize boreholes during drilling operations.
Agriculture: Attapulgite powder is used as a soil conditioner and amendment to improve water retention, aeration, and nutrient availability in agricultural soils. It is also used as a carrier for agricultural pesticides and fertilizers, enhancing their efficacy and reducing environmental impact.
Construction and Building Materials: Attapulgite powder is added to cementitious materials, adhesives, sealants, and coatings to improve workability, durability, and moisture resistance. Its rheological properties help prevent sagging, cracking, and shrinkage in construction applications.
Personal Care and Pharmaceuticals: Attapulgite powder is used in cosmetic and personal care products, such as facial masks, lotions, and creams, for its absorbent and adsorbent properties. It is also used in pharmaceutical formulations as an excipient and binder in tablets and granules.
attapulgite powder is a versatile and valuable material with a wide range of properties and applications. From its unique composition and structure to its diverse industrial and commercial uses, it plays a vital role in numerous sectors, contributing to innovation, efficiency, and sustainability. As research and development efforts continue, the potential for attapulgite powder to address emerging challenges and meet evolving market demands remains promising.
Further reading:Attapulgite ultrafine powder grinding mill can grind attapulgite into a fine powder up to mesh. It is an environmentally friendly industrial stone powder mill with high efficiency and low energy consumption developed by SBM.
The industrial non-metallic ore grinding mills independently developed and produced by SBM mainly include HGM series ultrafine powder grinding mills and CLUM series superfine vertical mills. Both machines can produce 150- mesh ore powder, and the fineness can be adjusted freely.
In addition to grinding attapulgite, it can also grind dolomite, calcium carbonate, mica, calcite, kaolin, etc. They are widely used, have good grinding effects, and are highly praised by customers.
Attapulgite, also known as Palygorskite, refers to a clay mineral with attapulgite as the main component. Attapulgite belongs to the sepiolite group in mineralogical classification and is a crystalline hydrated magnesium aluminum silicate mineral.
Attapulgite has a certain degree of strong water absorption, mostly white and opaque, with a Mohs hardness of 2-3. It has good thickening, suspension, thixotropy, leveling, weather resistance, thermal insulation, environmental protection, etc.
There are more than two thousand uses of attapulgite, which are mainly used for vegetable oil refining, molecular sieve carriers, energy-saving building materials, oil drilling, salt, and high-temperature resistant mud raw materials.

The specifications of attapulgite powder are 100 mesh, 200 mesh, 325 mesh, 800 mesh, mesh, mesh, mesh, mesh, and other finenesses. In different application areas, different finenesses are required. The fineness of SBM’s ultrafine grinding mills can be adjusted freely, and customers can flexibly produce according to the needs of downstream industries.
Attapulgite powder production process, which includes attapulgite ore raw material crushing, grinding, classification processing, and other processes.
Stage 1: Crushing
The large attapulgite is initially crushed and processed by the crusher. According to the size of attapulgite raw materials and different output requirements, crushers of corresponding specifications can be selected, such as jaw crusher, impact crusher, cone crusher, etc.
Stage 2: Grinding
After crushing, the attapulgite is evenly lifted from the bottom up to the silo by the bucket elevator, and is fed into the ultrafine grinding mill by the electromagnetic feeder in an orderly manner, and is fully ground in the grinding chamber.
Stage 3: Classification
The classifier is then classified, the unqualified fine powder is returned to the host for re-grinding, and the powder that meets the fineness is sent to the finished product silo through the pipeline device with the airflow.
Attapulgite is widely used because of its good properties. After crushing and grinding, attapulgite powder can be obtained, which still retains good characteristics and has a larger application market. According to the fineness of attapulgite powder, its processing can be divided into rough grinding and fine grinding. The industrial ore mill developed and produced by SBM can meet the grinding needs of attapulgite, and is environmentally friendly, energy-saving, efficient, and high-yield.

The newly designed grinding roller grinding ring grinding curve improves the grinding efficiency. The production capacity is 40% higher than that of jet mills and stirring mills, and the energy consumption is only 30% of that of jet mills.
Equipped with multi-head cage type powder concentrator. The fineness of the product can be adjusted arbitrarily between 150- mesh, and the one-time screening rate can reach d97≤5μm.
The lubrication device is installed outside the main shaft, which can realize external non-stop lubrication and continuous production for 24 hours.
HGM ultra-fine pulverizer is equipped with a high-efficiency pulse dust collector, so there will be no dust pollution during the operation of the entire crushing system. Equipped with silencer and anechoic room to reduce noise.
SBM specially designed a unique roller shell and liner grinding curve, which can greatly improve the working efficiency of the mill and improve the whiteness and cleanliness of the finished product.
Using a PLC control system and multi-head powder selection technology, it can precisely control the working parameters of the equipment such as grinding pressure and speed. Compared with ordinary mills, the energy consumption of this mill can be reduced by 30%-50%.
The contact point between the roller shell and the grinding disc liner adopts electronic limit technology and mechanical limit protection technology, which can avoid the destructive impact caused by machine vibration and ensure the stability of operation.
Through the reversible structure and hydraulic adjustment system, the operator can easily and quickly move the grinding roller out of the machine body, inspect and replace the roller shell and liner, and perform other maintenance operations to reduce downtime losses.
