Bentonite is the most widely used raw material in clumping cat litter manufacturing, but many newcomers still ask the same question: how is cat litter actually made from bentonite ore at an industrial scale?
This article explains the complete bentonite cat litter production process, focusing on processing steps, machinery selection, and output control.

Raw Bentonite Ore Preparation

The production of bentonite-based cat litter starts from natural bentonite ore, usually calcium bentonite or sodium bentonite. After mining, raw ore blocks contain large lumps, high moisture, and impurities, making direct granulation impossible.

Primary processing includes:

Ore crushing to reduce large stones

Temporary storage for moisture balancing

Optional sodium activation for improved clumping performance

At this stage, manufacturers already decide whether the final product will be clumping cat litter, non-clumping mineral litter, or industrial absorbent granules, as this affects downstream equipment configuration. Click here to get more！

Crushing and Drying for Cat Litter Production

After pre-crushing, bentonite enters a fine crushing system, typically using a hammer crusher or cage mill. The goal is to control particle size while minimizing excessive powder.

Drying is a critical step in bentonite cat litter manufacturing. Rotary drum dryers are commonly used to reduce moisture content to a stable range, ensuring:

Strong water absorption

Stable granule formation

Reduced dust during screening and packaging

Proper drying directly impacts final litter performance and storage stability.

Granulation Methods for Bentonite Cat Litter

Granulation is the core step in turning bentonite powder into commercial cat litter. The most common options include:

Disc granulation for small to medium capacity

Drum granulation for continuous, large-scale production

In a bentonite cat litter granulation line, water spraying systems control pellet size, while rolling motion ensures smooth, rounded granules. Compared with extrusion, disc and drum granulation offer better adaptability to mineral materials.

Granule size is typically controlled between 1–4 mm, depending on market requirements.

Screening, Cooling, and Dust Control

After granulation, cat litter pellets pass through:

Rotary screening machines to separate qualified granules

Return systems for oversized or undersized particles

Cooling sections to improve pellet strength

Dust collection systems are essential in industrial cat litter plants, improving workshop environment and reducing material loss.

Packaging and Finished Product Handling

The final step involves automatic weighing and packing machines, supporting:

Small retail bags

Bulk cat litter packaging for wholesalers

A well-designed bentonite cat litter production line ensures uniform granule size, consistent clumping performance, and efficient output. Welcome to consult YUSHUNXIN to get your cat litter production line.

Conclusion

From bentonite ore crushing to finished litter packaging, cat litter manufacturing is a process-driven industry. Choosing the right process flow and equipment configuration allows manufacturers to control cost, quality, and production capacity effectively.
