Bentonite Processing Flow

2020-11-19

Bentonite is a water-bearing clay mineral mainly composed of montmorillonite, which can be divided into sodium bentonite and calcium bentonite.Because of its various special properties, it is called “all-purpose” clay. It can be used as binder, suspension agent, filling material, catalyst, etc. It is widely used in petroleum exploitation, directional crossing, iron and steel casting, metallurgical pellets, chemical coatings and other fields.

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

Stage 1: Fragmentation

The feed fineness (15mm-50mm) of large bentonite can be entered into the mill by crushing through the crusher.

Stage 2: Grinding

The crushed bentonite is sent to the silo by the hoist, and then sent to the grinding room of the mill by the vibrating feeder for uniform and quantitative grinding.

Fine powder processing LM vertical roller mill, MTW European version of the mill, MRN European version of intelligent mill;

XZM ring and roll micro-grinding and LUM ultra-fine vertical grinding can be used for ultra-fine powder processing.HM European coarse grinding mill is available for processing.

Stage 3: classification

The bentonite powder after grinding is graded by the separator, and the unqualified powder is graded by the separator and returned to the main machine for grinding again.

Stage 4: Gathering powder

The bentonite powder conforming to fineness is separated and collected in the dust collector along with the air flow through the pipeline. The collected finished powder powder is sent to the finished product bin by the conveying device through the discharge port, and then packaged by the powder tanker or the automatic packing machine.
