CORE COMPONENTS
At RICHI MANUFACTURE, equipment quality management is always the top priority, and product quality is guaranteed through multiple authoritative certifications such as ISO, CE, BV, and SGS, as well as stringent quality control processes.
For over 30 years, RICHI has continuously invested in the research and development and process optimization of pellet processing equipment, building a comprehensive technology R&D system and quality management system. Through independent technology accumulation, international standard certification, and rigorous production management, we ensure that every piece of equipment is characterized by stable performance, reliable quality, and strong adaptability to the global market.
Siemens Motors
During the cat litter pelleting process, the motor needs to continuously drive the pelleting system to withstand a large load. Therefore, the stability of the motor directly affects the production efficiency and operational reliability of the equipment. The RICHI cat litter pellet machine is equipped with an industrial-grade Siemens high-quality drive motor, which can maintain efficient and stable power even under long-term, high-intensity operation.
Ring Die and Pressure Roller
The ring die and pressure roller are the core components of the pellet mill. They work together like a “mold” and a “press head,” forcing loose cat litter material into the ring die and extruding dense cat litter pellets. They are typically made of 42CrMo alloy steel or 40CrMnTi, and undergo a carburizing heat treatment process to enhance wear resistance.
Variable frequency feeder
The core function of a variable frequency feeder is to precisely control the flow rate of raw materials into the pelleting chamber via a variable frequency motor, providing a stable and matched material flow to the ring die and pressure rollers, preventing material accumulation that could lead to blockages. This automatic adjustment ensures stable operation of the equipment under optimal load, directly extending the lifespan of core components such as the ring die and pressure rollers.
Cutter
The cutter is a key component that determines the final size of the cat litter pellets. It is installed on the outside of the ring die and cuts the cat litter extruded from the ring die at a certain length. Cat litter pellets are very fine, so RICHI has strict requirements for the cutting process to ensure the uniformity and high quality of the finished pellets.
Stainless steel conditioner
Conditioners play a crucial role in the production of cat litter using certain raw materials, performing “maturation and homogenization” processes. They can sterilize the materials, improve water resistance, and enhance molding properties, such as in the production of tofu cat litter. The stainless steel material ensures product purity and prevents impurities from contaminating the materials.
Ring mold lifting device
The ring die lifting device is a specialized auxiliary tool designed by RICHI for high-capacity cat litter pellet mills, used for replacing and disassembling ring dies. The ring die is one of the heaviest core components of the pellet mill; manual replacement is time-consuming, labor-intensive, and poses safety hazards. This device effectively reduces labor intensity and improves replacement efficiency.
SKF Bearings
Bearings are important and easily worn components in pellet mills. SKF bearings have strong pressure resistance and wear resistance, ensuring stable operation of the equipment for a long time in heavy-load and high-dust environments. They can significantly improve the smoothness of the main drive, reduce the failure rate, and extend the overall service life of the equipment.

QUESTIONS
Can various grasses be used as raw materials for making cat litter?
Yes. Many people are now choosing to use grass-based raw materials to make cat litter, such as alfalfa, hay, wheat straw, and rice straw. These herbaceous plant fibers can be used to make plant-based cat litter according to the formula.
However, it should be noted that the absorbency, clumping, and granule strength of herbaceous fibers are often not stable enough. In actual production, it is more common to process the grass into various fibers or powders and then blend them with other raw materials. For example: grass fiber + corn starch can enhance clumping and shaping; grass fiber + tapioca starch can improve granule strength; and blends with plant gums, soybean residue, sawdust, etc.
If you want to use grass-based raw materials to make cat litter, we suggest you talk to our engineering experts. We can help you find the most suitable plant-based cat litter formula, recommend the most suitable grass cat litter pellet machine configuration, optimize your production process and cat litter quality based on your raw materials, and help you build a cat litter project that can quickly achieve a return on investment.
What wood materials are suitable for our Wood Cat Litter Pellet Machine?
Generally speaking, our Wood Cat Litter Pellet Machine is suitable for most wood materials, such as pine, fir, wood chips, sawdust, wood fibers, and wood processing scraps.

What happens to non-conforming particles generated during production?
They are returned to the production line for further granulation. It’s normal for some particles to be too large, too small, or broken during production. These remaining particles can be collected through screening. As long as the raw materials are not contaminated, they can be sent back to the crushing, mixing, or granulation process for reprocessing via a return material conveying system. This reduces raw material waste and improves the overall yield. When designing production lines, RICHI rationally arranges return routes based on the characteristics of the raw materials to maximize their utilization.
What is the price of a cat litter pellet machine?
The price of a single cat litter pellet machine is approximately $7,000-$100,000 USD, as the equipment configuration varies significantly depending on the project. Factors such as raw material type, production capacity, pellet size, die specifications, motor configuration, and level of automation all affect the price. For example, a small tofu cat litter pellet machine with a capacity of 500 kg/h will require different configurations and investments than a wood or bentonite cat litter pellet machine with a capacity of 3–5 t/h. A more accurate equipment quote can only be provided after the raw materials and production capacity are determined.
What are the prospects for investing in cat litter production?
The cat litter market holds enormous potential. With the increasing number of cat-owning households, cat litter has become a staple in pet daily consumption, and different regions have varying demands for products such as tofu cat litter, bentonite cat litter, wood cat litter, and paper cat litter.
For the production side, in addition to considering market demand, it’s crucial to assess local raw material availability and sales channels. If the local area has abundant low-cost raw materials such as sawdust, soybean residue, bentonite, and waste paper, these resources can be utilized to produce corresponding cat litter products, reducing raw material transportation and procurement costs. Therefore, when investing in a cat litter production project, it’s essential to consider local raw material supply, target market, product type, 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. 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.
