How to Make Bentonite Granules?

Creating high-quality bentonite granules is essential for various industrial applications, from agriculture to chemicals. This process requires precision, appropriate machinery, and an understanding of the granulation process. In this detailed guide, you will discover how to efficiently produce bentonite granules, focusing on the machinery involved and the reasons behind the choice of specific equipment.

Understanding the Raw Materials for Bentonite Granulation

Before diving into the granulation process, one must recognize the importance of the raw materials used. Bentonite, a highly absorbent clay, forms the base of the granulation process. Depending on the intended use of the granules, additional materials might be mixed with bentonite to enhance its properties. These can range from polymers for water retention in agricultural applications to minerals that improve its strength for industrial use. The choice of raw materials is crucial as it directly affects the quality and characteristics of the final granules. Read more.

The Role of the Double Roller Extrusion Granulator in Bentonite Granulation

At the heart of the bentonite granulation process lies the double roller extrusion granulator, a machine designed to compact and form the raw materials into dense, uniform granules. Unlike other granulation methods, this process does not require the addition of liquids, making it an ideal choice for materials that are sensitive to moisture. The machine’s precision allows for the control of granule size and density, ensuring that the final product meets specific requirements.

Why Choose Horizontal Mixers and Vertical Crushers for Your Production Line?

For a seamless and efficient bentonite granulation process, incorporating horizontal mixers and vertical crushers into the production line is advisable. The horizontal mixer ensures that the raw materials are thoroughly blended before granulation, providing a consistent mixture that promotes uniform granule quality. On the other hand, the vertical crusher plays a critical role in processing oversized granules or materials that clump together, crushing them back into fine particles that can be reintroduced into the granulation process. This combination not only optimizes the process but also minimizes waste, enhancing overall production efficiency.

Configuring a Bentonite Granulation Production Line

When setting up a production line for bentonite granules, understanding the synergy between different machines is key. Starting with the vertical crusher, raw materials are brought to a uniform size, ensuring a smooth feed into the horizontal mixer. Here, any additional ingredients are combined with bentonite to achieve the desired mixture. The heart of the operation, the double roller extrusion granulator, then compacts this mixture into dense granules. This methodical approach guarantees high-quality granules with minimal resource wastage.


The production of bentonite granules is a sophisticated process that demands precision and the right equipment. By choosing machines like the double roller extrusion granulator, horizontal mixers, and vertical crushers, manufacturers can ensure the production of high-quality granules. This not only optimizes the granulation process but also aligns with industrial standards, ensuring that the final products meet the needs of various applications.

How to make cat litter pellets with bentonite as materials

Introduction to Creating Bentonite Cat Litter Pellets

Bentonite is a highly absorbent clay material that is often used to produce cat litter pellets. These pellets are favored by cat owners for their ability to clump together when wet, making it easier to clean up after their pets. The process of making bentonite cat litter pellets involves several steps, from preparing the raw materials to the final packaging. In this guide, we’ll walk you through the production process so you can understand how to craft your own bentonite cat litter pellets.

Procuring Quality Bentonite Clay

Sourcing the Material

To start, you’ll need to source high-quality bentonite clay. This clay can be purchased in bulk from mining companies or suppliers specializing in industrial minerals. The quality of the bentonite will influence the absorbency and clumping ability of the final product, so choose a reliable source.

Preparing the Bentonite for Pelletizing

Grinding the Bentonite

Once you have the raw clay, it must be ground into a fine powder. This increases the surface area, making the material more effective at absorbing liquids. You can use a variety of grinding machines, such as a hammer mill, to achieve the desired consistency.

Moisture Content Adjustment

It’s critical to adjust the moisture content of the bentonite powder to create quality pellets. The mixture should be moist enough to form into pellets but not so wet that it becomes sticky or unmanageable. A moisture content of around 10-12% is ideal for pelletizing.

The Pelletizing Process

Forming the Pellets

With the moisture content adjusted, the next step is to form the powder into pellets. This can be done using a pellet mill, which compresses the powder into small, dense pellets through a die. The size of the die will determine the size of the pellets, which you can adjust according to your preference or market demand. There is also some granulators for your choice. Such as disk pelletizer and drum granulation machine.

Drying the Pellets

Once formed, the pellets need to be dried to remove excess moisture. This is typically done in a granulating dryer where the pellets are tumbled in a heated chamber. Properly dried pellets will have a moisture content of around 5-8%, ensuring they are hard and durable enough for packaging and use.

Ensuring Quality and Safety

Screening for Consistency

After drying, the pellets should be screened to ensure uniform size and quality. This step also removes any dust or fine particles that could cause the litter to be dusty when poured into the litter box.

Testing for Absorbency

Quality control tests should be performed to measure the absorbency and clumping ability of the pellets. This ensures that they perform as expected when used by consumers. You may need to adjust the formulation or processing conditions based on the results to achieve the best product.

Packaging and Storage

Bagging the Pellets

The final step is to package the pellets for sale. Typically, bentonite cat litter pellets are bagged in durable plastic or paper bags that can withstand the weight and prevent moisture from affecting the product during transport and storage.

Storing Properly

Store the bagged pellets in a dry, cool place to maintain their quality. Any exposure to excessive humidity or water before use could cause the pellets to clump prematurely and reduce their effectiveness.

Marketing and Distribution

Branding and Marketing

Develop a brand and marketing strategy to make your bentonite cat litter pellets stand out in the market. Highlight the eco-friendly and natural aspects of bentonite, as well as the superior clumping and odor control properties of your product.

Distribution Channels

Establish distribution channels to reach your target market. This can include pet stores, supermarkets, online retailers, or direct sales through a dedicated website.


Making bentonite cat litter pellets is a process that requires careful preparation, precise control of moisture content, and thorough quality control. By following these steps, you can produce high-quality, absorbent cat litter pellets that meet the needs of pet owners. Remember to focus on sustainability and proper marketing to ensure your product is both environmentally friendly and successful in the competitive pet care market.
