200-325 mesh bentonite grinding mill for paper drilling industry

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 its main mineral component. Bentonite can be divided into sodium-based bentonite (alkaline soil), calcium-based bentonite (alkaline-earth soil), natural bleaching earth (acidic soil or acid white clay), and calcium-based bentonite includes calcium-sodium-based and calcium-magnesium-based.

Bentonite processing technology

1.Sodiumization stage: Most of the bentonite in nature is calcium-based bentonite, and the performance of calcium-based bentonite is poorer than that of sodium-based bentonite.

2.Drying stage: The sodium bentonite has a high moisture content and needs to be dried by a dryer to reduce the moisture content.

3.Milling stage: The dried bentonite is crushed until the ore that meets the feeding requirements of the mill is lifted by the elevator to the storage hopper, and then the electromagnetic vibrating feeder evenly feeds the main machine of the mill for grinding.

4.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.

5.Powder collection stage: the fine powder enters the powder collection system with the air flow 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 packaged with a powder tanker or an automatic packing machine.
