Cat litter manufacturing may appear simple from the outside, but producing consistent, low-dust, absorbent, and easy-to-use cat litter on a commercial scale requires a carefully designed processing system. Different types of cat litter—including bentonite, tofu, wood, corn, cassava, and other plant-based products—require different raw materials and production technologies.
A complete production system may involve raw material receiving, cleaning, crushing, grinding, drying, batching, mixing, pelletizing or granulation, cooling, screening, coating, dust collection, and packaging. Therefore, choosing the right cat litter manufacturing equipment is one of the most important decisions when establishing a cat litter production business.
This article introduces the main equipment used in cat litter production, explains what each machine does, and shows how these machines can be integrated into a complete production line.
1. What Determines the Equipment Needed for Cat Litter Production?
There is no single equipment configuration suitable for every cat litter product.
The required machinery depends mainly on:
- Type of cat litter
- Raw material
- Raw material moisture
- Raw material particle size
- Production capacity
- Target pellet size
- Product density
- Clumping requirements
- Odor-control requirements
- Packaging specifications
- Automation level
For example, a tofu cat litter production line based on soybean residue may require drying, grinding, mixing, pelletizing, cooling, and screening.
A wood cat litter line based on dry sawdust may require less crushing.
Bentonite cat litter follows a different mineral-processing and granulation process.
Therefore, the first step is always to determine the product and raw material before selecting machinery.
2. Raw Material Receiving Equipment
The production process starts with receiving raw materials.
Depending on the raw material, a factory may use:
- Receiving hopper
- Dumping station
- Belt conveyor
- Screw conveyor
- Bucket elevator
- Storage bin
- Automatic feeder
The receiving system transfers raw materials into storage or directly into the preprocessing section.
A properly designed receiving system can reduce manual handling and improve material flow.
For large factories, automatic conveying systems are especially useful because they connect different processing machines into a continuous production line.
3. Raw Material Storage Equipment
Storage equipment protects raw materials from contamination and environmental conditions.
Common equipment includes:
- Silos
- Storage bins
- Hoppers
- Warehouse storage systems
For plant-based cat litter, moisture control is particularly important.
Sawdust, soybean residue, corn fiber, and other biomass materials can absorb moisture during storage.
Excessive moisture can affect:
- Grinding
- Mixing
- Pelletizing
- Drying
- Storage stability
Therefore, storage facilities should be designed according to the characteristics of the raw material.
4. Cleaning Equipment
Raw materials may contain unwanted materials.
A cleaning system can remove:
- Stones
- Metal
- Plastic
- Soil
- Oversized particles
- Other contaminants
Typical cleaning equipment includes:
Vibrating Screen
Used to separate materials according to particle size.
Magnetic Separator
Used to remove ferrous metal particles.
Rotary Screen
Can be used for continuous screening and material separation.
Cleaning protects downstream equipment and helps improve finished-product quality.
5. Crushing Equipment
Large raw materials need to be reduced before further processing.
Crushing equipment may be required for:
- Wood chips
- Bamboo
- Agricultural residues
- Large plant fibers
- Mineral lumps
A crusher reduces the material into smaller pieces that are easier to grind or granulate.
For example, wood chips can be processed into smaller particles before entering a hammer mill.
If the raw material is already in the form of fine sawdust, a separate crusher may not be necessary.
6. Hammer Mill or Grinding Equipment
A hammer mill is commonly used to reduce raw materials to a suitable particle size.
The grinding process is important because particle size affects:
- Pellet formation
- Pellet durability
- Density
- Absorption
- Surface quality
- Dust generation
For plant-based cat litter, grinding can produce a more uniform material before mixing and pelletizing.
However, excessive grinding should be avoided because it increases electricity consumption and may produce excessive dust.
The ideal grinding size depends on the material and the final product.
7. Drying Equipment
Drying is one of the most important processes in many cat litter production lines.
Plant-based materials can contain significant moisture.
A commercial dryer may be used to reduce moisture before or after pelletizing.
Common drying equipment includes:
- Rotary drum dryer
- Continuous dryer
- Hot-air drying system
A rotary dryer is commonly used for continuous industrial production.
The drying system should be selected according to:
- Initial moisture
- Target moisture
- Production capacity
- Raw material characteristics
- Available heat source
Efficient drying can significantly reduce production costs.
8. Batching Equipment
Some cat litter products contain several ingredients.
For example, a tofu cat litter formula may contain:

A horizontal mixer is commonly used for this purpose.
The mixer distributes:
- Main raw materials
- Binders
- Starch
- Odor-control additives
- Other functional materials
Uniform mixing is important because every portion of the material should have a similar composition.
Poor mixing can cause inconsistent:
- Absorption
- Pellet strength
- Density
- Odor control
- Clumping performance
10. Moisture Addition Equipment
Before pelletizing, the material may require moisture adjustment.
A water spraying system can add controlled amounts of moisture.
The system may include:
- Water tank
- Pump
- Spray nozzles
- Flow-control system
Moisture should be distributed evenly throughout the material.
Too much moisture may result in:
- Weak pellets
- Difficult drying
- Higher energy consumption
- Material sticking
Too little moisture can make pellet formation difficult.
Therefore, moisture adjustment should be carefully controlled.
11. Cat Litter Pellet Mill
For many plant-based cat litter products, the pellet mill is one of the core machines.
A pellet mill compresses prepared material through holes in a die to produce pellets.
The main components include:
- Die
- Pressure rollers
- Feeder
- Main drive system
- Cutting system
The pellet mill influences:
- Pellet diameter
- Density
- Strength
- Production capacity
- Surface appearance
Different die specifications can be used to produce different pellet sizes.

12. How the Pellet Mill Works
The basic working principle is straightforward.
First, prepared material enters the pellet mill through the feeder.
The material is distributed into the compression chamber.
Rotating rollers press the material against the die.
Pressure forces the material through the die holes.
Continuous extrusion produces cylindrical pellets.
A cutter then controls pellet length.
After pelletizing, the fresh pellets proceed to drying or cooling depending on their moisture content.
13. Granulation Equipment
Not all cat litter products are manufactured with a conventional pellet mill.
Some products use granulation equipment to create particles with specific shapes and sizes.
A granulator can be selected according to:
- Raw material
- Product shape
- Particle size
- Density
- Production capacity
This is particularly relevant for certain mineral-based cat litter products.
Therefore, the forming machine should be selected according to the intended product rather than simply choosing a standard pellet mill.
14. Cooling Equipment
Fresh pellets may have elevated temperatures after drying or pelletizing.
A cooler helps reduce the product temperature before screening and packaging.
Cooling equipment can:
- Reduce pellet temperature
- Improve storage stability
- Reduce condensation
- Protect packaging
- Improve handling
For continuous production, the cooler should be matched to the output of the upstream equipment.
An undersized cooler can become a bottleneck.
15. Screening Equipment
Screening equipment separates finished cat litter from unwanted particles.
A screening machine can remove:
- Fine powder
- Broken pellets
- Oversized particles
- Irregular granules
Common options include:
- Vibrating screen

- Multi-layer screening machine
Screening improves particle-size consistency and reduces excessive fines.
Suitable fines may be recycled into the production process, depending on the formula.
16. Coating and Spraying Equipment
Some cat litter products require post-processing treatment.
A coating or spraying machine can apply:
- Fragrance
- Odor-control ingredients
- Functional additives
- Other surface treatments
For example, an odor-control additive can be applied after pelletizing.
A controlled spraying system helps achieve a more uniform distribution.
The exact treatment depends on the product formula and target market.
17. Dust Collection Equipment
Dust collection should be considered an essential part of commercial cat litter manufacturing.
Dust can be generated by:
- Crushing
- Grinding

- Pelletizing
- Cooling
- Screening
- Conveying
- Packaging
A dust collection system may include:
- Cyclone
- Baghouse filter
- Dust collector
- Ductwork
- Exhaust fan
An effective dust-control system can improve the factory environment and reduce product losses.
It also helps prevent excessive dust from accumulating around production equipment.
18. Conveying Equipment
Conveying equipment connects different machines.
Common options include:
Belt Conveyor
Suitable for continuous transportation of many bulk materials.
Screw Conveyor
Useful for controlled transportation of powders and granular materials.
Bucket Elevator
Used for vertical material transportation.
