Bentonite Clay and Powder
Bentonite clay, derived from volcanic ash deposits, has gained widespread popularity for its versatile applications across various industries. As a highly absorbent and expansive material, it finds utility in numerous sectors ranging from cosmetics to construction. This article delves into the definition, common uses, key characteristics, challenges in bulk material conveying, and the ideal UniTrak equipment tailored for handling Bentonite clay and powder.
At a Glance
Bentonite clay, also known as montmorillonite, is an absorbent aluminum phyllosilicate clay consisting mostly of montmorillonite. It typically forms from weathering of volcanic ash in the presence of water. Due to its unique properties, Bentonite clay exists in both powder and granular forms, with varying degrees of purity and particle sizes.
Bentonite clay exhibits several key characteristics that influence its handling and processing:
- Absorbency: Bentonite clay has high water absorption capacity, making it swell and increase in volume when hydrated.
- Plasticity: It demonstrates excellent plasticity, enabling it to form a tight seal when used as a barrier material.
- Thixotropy: Bentonite clay exhibits thixotropic behavior, meaning it becomes less viscous when agitated or sheared, and returns to its original state when left undisturbed.
- Abrasive: In its dry form, Bentonite clay can be abrasive, causing wear and abrasion to conveying equipment.
- Cohesiveness: It tends to clump together, posing challenges during conveying and processing.
Common Uses
- Cosmetics: Bentonite clay serves as a key ingredient in skincare products such as masks and scrubs due to its ability to absorb excess oil and impurities from the skin.
- Pharmaceuticals: It finds application in pharmaceutical formulations as a binder, disintegrant, and suspending agent.
- Construction: Bentonite clay is utilized in drilling fluids for oil and gas wells, as a sealant in landfills and ponds, and as a binder in the production of foundry sands.
- Environmental Remediation: It is employed in environmental cleanup processes for its ability to absorb heavy metals and toxins from contaminated soil and water.
- Agriculture: Bentonite clay is used in agriculture as a soil conditioner to improve soil structure and water retention.
Challenges in Conveying
Bulk material conveying of Bentonite clay and powder presents several challenges:
- Abrasion: The abrasive nature of dry Bentonite clay can cause wear and damage to conveying equipment, leading to increased maintenance costs.
- Cohesiveness: Bentonite powder tends to form clumps and agglomerates, leading to flow issues and blockages in conveying systems.
- Hygroscopicity: Bentonite clay is hygroscopic, meaning it readily absorbs moisture from the atmosphere, leading to caking and handling difficulties.
- Dust Generation: Handling Bentonite powder can generate airborne dust, posing health hazards and requiring dust containment measures.
