Core equipment for the cat litter pellet production line
01.
Crushing Equipment
We offer various grinding machines, including wood grinders, grain grinders, multi-functional grinders, and shredders.

Crushing Equipment
We select the appropriate grinding equipment based on the hardness, fibrous nature, and moisture content of raw materials—such as soybean residue, wood, bentonite, and waste paper—to maximize grinding efficiency and minimize resource waste.
02.
Drying Equipment
We offer rotary dryers and mesh-belt circulation dryers suitable for drying various raw materials, such as grains and wood chips.

Drying Equipment
The moisture content of raw materials—particularly soybean residue, wood chips, and paper fibers—directly affects the granulation process. Drying the materials to an optimal moisture level facilitates granule formation and prevents issues such as moisture absorption and clumping during storage.
03.
Mixing Equipment
Available mixing equipment includes single-shaft double-layer paddle mixers, twin-shaft paddle mixers, single-shaft double-ribbon mixers, and single-ribbon mixers.

Mixing Equipment
Ingredients such as soybean residue, starch, and plant gum (for tofu cat litter) or bentonite, activated carbon, and deodorizers (for bentonite cat litter) require thorough mixing to ensure consistent product performance. Mixers ensure these diverse raw materials and additives are blended into a truly homogeneous mixture.
04.
Cooling Equipment
Counter-flow coolers are capable of rapidly and efficiently lowering the temperature of the finished granules.

Cooling Equipment
Cat litter granules emerge from the granulation equipment at high temperatures and are not yet fully stable. Cooling lowers the temperature and stabilizes the granule structure, reducing breakage and clumping during subsequent screening and packaging processes.
05.
Screening Equipment
Options include rotary pre-cleaning screens, powder cleaning screens, plansifters, vibrating screens, and rotary grading screens.

Screening Equipment
Not all granules produced are suitable for immediate sale; oversized, undersized, and broken granules must be removed. Screening ensures uniform particle size in the final product while allowing substandard granules to be recycled and reprocessed, thereby reducing raw material waste.
06.
Spraying Equipment
Spraying units are primarily used to apply liquid functional additives evenly onto the surface of the formed cat litter granules.

Spraying Equipment
Examples of such additives include fragrances, deodorizers, antibacterial agents, and plant extracts. The spraying system controls the dosage and spray uniformity, facilitating stable production of cat litter products with diverse scents and functionalities.
07.
Packaging Equipment
Handles semi-automatic or fully automatic weighing and packaging according to specific standards.

Packaging Equipment
Ultimately, the cat litter must be bagged according to various sales specifications—such as 2kg, 5kg, or 10kg. The packaging machine performs quantitative filling, bagging, and sealing; the level of automation is selected based on production scale, ensuring that the preceding production stages successfully culminate in market-ready finished products.
FREQUENTLY ASKED QUESTIONS ABOUT CAT LITTER PELLET MACHINES

Can various types of grass serve as raw materials for cat litter?

What types of wood raw materials are suitable for the wood cat litter pellet machine?
Generally speaking, our wood cat litter pellet machines are compatible with the vast majority of wood-based raw materials, such as pine, fir, wood chips, sawdust, wood fibers, and offcuts from timber processing. We also offer pre-processing equipment tailored to various wood materials, ensuring seamless integration with the production line and providing solutions for raw material crushing, drying, and blending.
If you are interested, please speak with our technical consultants. We can design and recommend the ideal pellet machine configuration based on your specific raw materials and cat litter formulas.
Do different types of cat litter require different pellet machines?
Not necessarily entirely different machines, but because different raw materials have distinct molding characteristics, the machine configurations will vary. Materials such as soybean dregs, wood chips, bentonite, and paper fiber require specific granulation methods selected based on the formula, desired pellet size, and production capacity.
We offer customized equipment configurations for various production processes, aiming to maximize efficiency and minimize energy consumption, thereby helping you achieve the best possible return on investment.
Can the cat litter production line produce cat litter in various scents and colors?
Absolutely. The production line allows for the addition of various pigments, fragrances, and deodorizing agents based on specific product formulas, enabling the production of cat litter in scents such as unscented, lavender, green tea, and peach, as well as in various colors. Additionally, by selecting plant-based raw materials with natural colors and aromas—and optimizing the raw material ratio and processing techniques—the cat litter can retain the natural color and scent of the raw materials without the need for artificial additives.
If you would like to learn more about the process of producing colored or scented cat litter, please feel free to contact us; we can provide a detailed explanation tailored to your specific raw materials.
How is the cat litter pellet size adjusted?
First, it is important to understand that pellet size is primarily controlled by the granulator’s die, compression parameters, and screening equipment. To change the pellet diameter, one can simply replace the die with one featuring a different hole size; pellet length and forming quality are adjusted by modifying granulation parameters; finally, a screening process removes the few pellets that are too large or too small, resulting in cat litter that meets specific size requirements. The screened-out material can be returned to the production line for further granulation.
How are substandard pellets generated during production handled?
They are returned to the production line for further pelletizing. It is normal for some oversized, undersized, or broken pellets to appear during production; these retained materials can be collected via screening. Provided the raw materials are uncontaminated, these materials can be fed back into the grinding, mixing, or pelletizing stages for reprocessing via a recycle conveying system. This approach minimizes raw material waste and improves the overall finished product yield. When designing production lines, RICHI strategically plans the material recycling route based on raw material characteristics to maximize material utilization.
What is the price of a cat litter pellet machine?
The price of a single cat litter pellet machine ranges from approximately USD 7,000 to USD 100,000, as equipment configurations vary significantly between projects. Factors such as raw material type, production capacity, pellet size, die specifications, motor configuration, and the level of automation all influence the price. For instance, the configuration and investment required for a small-scale tofu cat litter pelletizer (500 kg/h) differ greatly from those for a wood or bentonite cat litter pelletizing system (3–5 t/h). A precise equipment quotation can only be provided once the raw materials and production capacity have been determined.
What are the prospects for investing in cat litter production?
The cat litter market holds immense potential. As the number of cat-owning households grows, cat litter has become a staple in daily pet care consumption, with varying regional demands for products such as tofu, bentonite, wood, and paper-based cat litter.
From a production standpoint, success depends not only on market demand but also on local raw material availability and sales channels. If low-cost raw materials—such as sawdust, bean dregs, bentonite, or waste paper—are abundant locally, they can be utilized to manufacture corresponding cat litter products, thereby reducing raw material procurement and transportation costs. Therefore, investment decisions regarding cat litter production projects should be based on a comprehensive assessment of local raw material supplies, target markets, product types, and planned production capacity.
What raw materials can a paper cat litter pellet machine process? Are drying and additives required during production?
Yes. Paper cat litter pellet machines mainly process paper fiber raw materials such as waste paper, waste cardboard, newspapers, book paper, and pulp. If the raw material has a high moisture content, it usually needs to be dried first; if the raw material is relatively dry, the drying process can be reduced or eliminated depending on the actual situation. Before pelleting, the raw material needs to be crushed, screened, and mixed according to its condition.
If it is necessary to produce cat litter with specific functions, additives such as deodorizers, fragrances, and absorbent materials can be added during the mixing stage. The concentration and amount of fragrance can be adjusted according to the product positioning. Finally, the finished product is obtained through pelleting, cooling, and screening. Screening can separate excessively large particles and powder. The particle diameter can usually be adjusted by changing the mold, and the specific production capacity needs to be determined based on the type of raw material, the moisture content of the raw material, the particle size, and the target output.
