Bentonite Powder Plant to produce bentonite powder used as drilling mud

Time:2018年06月06日      Hits:

Sunco Machinery can supply Bentonite Powder Plant to produce bentonite powder, and the bentonite powder can be used as high quality drilling mud. 

Usually the drilling mud bentonite powder have two fineness: 200 mesh and 325 mesh bentonite powder according to different usage.

When dig out the raw bentonite from the ground, the moisture content of wet bentonite is still about 20-30%, and it is too wet to be grinded into powder by the bentonite mill.

Thus the Bentonite Powder Plant mainly includes bentonite dryer machine, and bentonite grinding mill.

--- Bentonite Dryer System is as follows:

01. As when we dig out the wet bentonite from the mining, some of the wet bentonite is lump type which is not easy to be heated and dried sufficiently by the bentonite powder dryer machine.

      Here we can use one hammer crusher / hammer mill to crush the raw wet bentonite into smaller size such as less than 10mm in advance.

02. To use belt conveyor or Bucket Elevator to send wet bentonite powder into the bentonite drying machines continuously.

03. Diesel burner and hot air furnace supply the high temperature air for the bentonite drying process. Usually the temperature near the outlet of the hot air furnace can be around 300 centigrades.

04. Beontonite powder dryer heat and dry the wet bentonite powder sufficiently, and reduce the moisture content to be about 12%,

05. High pressure draft fan makes the high temperature air into the bentonite drying machine, and make the exhaust air with water vapor and some dust out of the dryer, then goes into cyclone dust separator.

06. Cyclone dust separator separates the dust from the exhaust air and water vapor. The dust falls down onto the outlet belt conveyor together with the dry bentonite powder, and to be taken to the product storage area for package. The exhaust air and water vapor leaves the cyclone dust separator and then pass through the high pressure draft fan, finally goes into atmosphere.

01. Bentonite is crushed by hammer crusher to the size required which is suitable for the Bentonite Mill.

02. Then the crushed bentonite are elevated into a hopper by bucket elevator from which the bentonite is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for bentonite grinding mill. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the bentonite, send to the middle between ring and roller to accomplish the grind.

03. After this, the ground bentonite are carried by the air from the blower into the powder separator (Analyzer Machine) for screening. The fine bentonite powders are blow into the cyclone powder collector and are poured out through the output-powder valve as the final products, and the corase bentonite after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.

The bentonite powder product is as follows:
