Process design of 4-5 t/h bentonite cat litter factory in the United States


Brief description of bentonite cat litter production process:

This 4-5 t/h bentonite cat litter factory in the United States project selected RICHI's characteristic bentonite cat litter production technology.

The specific process is to crush, squeeze and stir the raw materials and caustic soda in a semi-dry state under normal temperature conditions to form a granular mixture, and then add a small amount of Water forms semi-dry granular material, which is a process technology of bentonite series through grinding, sieving, granulation, drying and other processes.

  1. Processing link
    After the raw materials are crushed and ground, a small amount of water is added to make the moisture reach between 15% and 25%, and then sent to the bentonite cat litter pellet machine for granulation.
  2. Drying link
    After the granulation is completed, the materials are sent to the dryer for drying through the conveyor belt.
  3. Finished product screening, packaging and warehousing links
    The dried products are screened and selected, bagged, weighed, sealed and stored in warehouse.

Casting grade bentonite production process

In addition to bentonite cat litter, as a bentonite processing plant, this customer also produces foundry grade bentonite. (This production line is original to the customer and is not provided by RICHI). But here, I would like to introduce to you its processing technology.

Casting-grade bentonite is mainly made of raw mineral soil. After natural drying, it is input to the crusher for crushing, ground by grind mill machine, and finally packaged.

  1. Drying of raw materials
    The raw bentonite soil is transported to the drying field and dried naturally to achieve a moisture content of about 5%.
  2. Crushing and screening
    After the material is dried, it is transported to the crusher via a conveyor belt, and then screened to meet the grinding requirements.
  3. Grinding link
    The raw materials are transported by the conveyor to the storage hopper on the main machine, and then are evenly and quantitatively sent to the main machine's grinding chamber through the electromagnetic vibrating feeder for grinding.
    The ground powder rises with the air flow of the fan and is classified by the analyzer. The fine powder enters the large cyclone collector with the air flow through the pipe, is separated and collected, and then is discharged through the powder outlet valve to become the finished powder (finished product).
  4. Finished product packaging link
    The finished products processed by grinder machines are transported to the finished product warehouse, bagged, weighed and sealed.
