Bentonite generally has a hardness of 1-2 (some are relatively hard), and a density of 2-3g/cm3. Also called bentonite, bentonite, or bentonite, it is a non-metallic mineral with montmorillonite as the main mineral component. It is generally white and light yellow, and it is light gray, light green, pink, and brown due to changes in iron content. Red, brick red, gray-black, etc. Hardness 1~2, density 2~3g/cm3. According to the type, content, and layer charge of montmorillonite, bentonite can be divided into sodium-based bentonite (alkaline soil), calcium-based bentonite (alkaline earth), natural bleaching earth (acidic soil or acid white clay), Calcium-based bentonite also includes calcium-sodium-based and calcium-magnesium-based.

Bentonite Processing Technology

1.  Crushing stage: large pieces of material are crushed by the crusher to the feed fineness that can enter the mill (15mm-50mm)

2. Milling stage: The small pieces of materials that meet the grinding conditions are uniformly and quantitatively entered into the grinding chamber of the mill through the conveying and feeding system, and are ground into powder in the grinding chamber.

3. Classification stage: The ground materials are classified through the powder classifier with the system airflow, and the unqualified powder is classified by the classifier and returned to the main mill for re-grinding.

4. Powder collection stage: the fine powder enters the powder collection system with the airflow through the pipeline, the air and powder are separated, and the finished powder is sent to the finished product silo by the conveying device, and then uniformly packed with a powder tanker or an automatic packing machine.
