bentonite processing plant machinery

A bentonite processing plant requires specialized machinery to process raw bentonite into various grades for industrial applications such as drilling mud, foundry sand, cat litter, and absorbents. Below is an overview of key machinery used in bentonite processing:

1. Crushing & Grinding Equipment
– Primary Crusher (Jaw Crusher) – Reduces large chunks of raw bentonite.
– Secondary Crusher (Hammer Mill/Cone Crusher) – Further crushes material into smaller pieces.
– Raymond Mill/Vertical Roller Mill/Ball Mill – Fine grinding to achieve desired particle size (usually 200-325 mesh).

2. Drying Equipment
– Rotary Dryer – Reduces moisture content (~30% down to ~8-12%) using hot air.
– Fluidized Bed Dryer – Efficient drying for finer particles.

3. Activation & Purification (For Sodium & Calcium Bentonite)
– Mixer/Pug Mill – Used for sodium activation (adding soda ash).
– Classifier/Air Separator – Removes impurities and controls particle size.

4. Granulation & Pelletizing (For Cat Litter/Foundry Sand)
– Disc Pelletizer/Pan Granulator – Forms bentonite into pellets or granules.
– Double-Shaft Mixer – Ensures uniform mixing before pelletizing.

5. Screening & Classification
– Vibrating Screen/Rotary Screen – Separates different particsizes.
– Air Classifier – Fine-tunes particle distribution.

6. Packaging Machinery
– Automatic Bagging Machine – For powdered or granular bentonite.
– *Bulk Loading System* – For large-scale industrial shipments.

Optional Advanced Processing:
– (For High-Purity Applications)
– Magnetic Separator → Removes iron impurities.
– Centrifuge → Further purification.
