cat litter pellet machine
Overview of Cat Litter Pellet Machine
Cat litter pellet machine is a professional equipment that adopts mold-pressing technology to produce cat litter pellets. Various pre-processed powdered raw materials (such as biomass materials like sawdust, pulp, straw, soybean meal, or mineral materials like bentonite and zeolite) are forced through the holes of a ring die under the strong extrusion of rollers.
During this process, the heat generated by high pressure and friction enhances the plasticity of the raw materials, consolidating them into continuous cylindrical strips. These strips are then cut by synchronized knives into uniform cat litter pellets. The cat litter pellet machine effectively improves key properties of the product, such as density, clumping ability, and water absorption, making it essential for standardized and large-scale production of cat litter.
RICHI Machinery offers various models of cat litter pellet machine, with a single-machine output ranging from 1 to 40 tons per hour, capable of producing full-specification pellets with a particle size of 2-12 mm. We can also provide customized services according to your specific needs.
Convert Any Material to Cat Litter pellet
RICHI cat litter pellet machine demonstrates strong raw material adaptability, capable of processing various types of cat litter raw materials to meet production requirements for different material compositions. During production, simply by replacing core components such as the ring die and pressure rollers, and adjusting process parameters, the machine can produce cat litter pellets of different materials, achieving multi-functionality with a single unit.
Depending on the characteristics of the raw materials, a conditioner can be optionally installed. Mineral cat litter typically requires a conditioner, while environmentally friendly cat litter generally does not.

It also has a fault self-diagnosis function, which automatically alarms and indicates the fault location when abnormalities occur, reducing the difficulty of manual operation.
How the Cat Litter Pellet Machine Works
Cat litter pellet machine adopts the die-pressing forming process, which can press raw materials such as wood chips, straw, soybean meal, soybean residue, wood shavings, bentonite and silica gel into granular cat litter.
The pelleting process for cat litter pellets made from different raw materials varies slightly, but the core steps all include : feeding → conditioning → extrusion forming → cutting.
First , the crushed raw material is evenly fed through a top-mounted feeder into the conditioner. The feeder is equipped with an anti-bridging device. For woody materials, a forced feeder is additionally installed to push the material into the pelleting chamber, effectively preventing clogging and ensuring continuous and efficient operation.
Next, it’s conditioning. This step is usually used for mineral materials. Inside the conditioner, the material is mixed with steam and vigorously agitated by high-speed dual-shaft paddles. This process fully softens and gelatinizes the material, enhancing its plasticity and adhesion to ensure the resulting pellets are firm and resistant to breaking apart.
Then, the conditioned material is then conveyed into the pelleting chamber. There, it is strongly compressed between the ring die and press rollers, forcing it through the die holes to form dense, solid strands.
Finally, when raw materials are extruded from the die holes of the ring die to form long strips, the synchronized cutter will immediately cut these extruded strips accurately according to preset parameters, finally producing finished pellets with uniform length and regular shape.

Application of Cat Litter Pellet Machine
The RICHI cat litter pellet machine is capable of producing various types of cat litter, including mineral-based, plant-based, silica crystal-based, and composite types. This versatility meets diverse requirements such as different feline physiologies (e.g., kittens, adult cats, sensitive cats), usage scenarios (e.g., indoor/outdoor, odor control needs), and cost budgets, effectively expanding the market coverage of finished cat litter products.
Mineral-Based Cat Litter
The main raw material of mineral-based cat litter is bentonite. It features high water absorption and strong clumping properties, with a relatively simple production process and low production cost.
Plant Fiber-Based Cat Litter
Plant fiber cat litter is made from agricultural by-products, featuring safety and low allergenicity. It includes tofu cat litter, corn cat litter, wood-based cat litter, etc.
To produce this type of cat litter, a conditioner usually needs to be installed on the pellet machine.
Silica Crystal-Based Cat Litter
Crystal cat litter uses high-purity silica gel as its core raw material. Its pellets features extremely strong water absorption capacity, and no dust, but carries certain safety risks.
Composite Cat Litter
Composite cat litter is produced by blending two or more raw materials in specific proportions, such as “bentonite + wood fiber” “corn cob + zeolite” .
It delivers enhanced overall performance but has higher costs.
