Bentonite processing technology

Bentonite powder is generally divided into coarse powder processing (0-3mm), fine powder processing (20 mesh-400 mesh, ultra-fine powder processing (400 mesh-1250 mesh) and micro-powder processing (1250 mesh-3250 mesh) four types.

The first stage: crushing

Large bentonite crushed by the crusher to be able to enter the mill feed fineness (15mm-50mm).

The second stage: grinding

After crushing the small pieces of bentonite through the elevator to the silo, and then by the vibrating feeder will be uniformly quantitatively fed into the mill grinding chamber for grinding.

The third stage: classification

After grinding, the bentonite powder is classified by the powder selector, and the unqualified powder is classified by the powder selector and returned to the main machine of the mill for regrinding.

The fourth stage: collecting powder

Meet the fineness of the bentonite powder with the airflow through the pipe into the dust collector for separation and collection, the collection of finished powder through the outlet by the conveyor device to the finished product silo, and then unified with the powder loading tanker or automatic baler for packaging.
