Bentonite Dryer

Bentonite Dryer is specially designed drying machine to dry the wet bentonite with moisture content about 25% to be about 10% so that it is suitable to be grinded by the Raymond Mill

Technical Parameters

Bentonite Dryer Introduction:

Bentonite Dryer is specially designed to dry the wet bentonite, and it is one kind of Rotary Drum Dryer. 

The natural bentonite is with about 25% moisture content, and it is not suitable to be grinded into fine bentonite powder directly by the Raymond Mill.

Thus the wet bentonite with moisture content about 25% needs to be reduced to be about 12% so that it is suitable to be grinded by the Raymond Mill into fine powder, usually it is 200 mesh bentonite powder.

Bentonite Dryer System Work Flow:

◆ Firstly, input belt conveyor sends the wet bentonite into bentonite dryer.

◆ On the inner wall of the cilinder/drum, there are many lifting plates which is welded according to one special methods.  When the Bentonite Dryer's drum is rotating, these lifting plates makes the bentonite up and down to mix with the hot air completely. Durng this process, the moisture is evaporated.

◆ On the another side of the Bentonite dryer, there is one high pressure draught fan which sucks out the exhaust air mixed with vapor, and then the exhaust air mixed with vapor goes into the cyclone dust separator.

◆ In the cyclone dust separator, the dust inside the exhaust air falls down and goes out through the discharging hole of the cyclone dust separator. The exhaust air goes into atmosphere directly through the chimney which is connected to the cyclone dust separator.

◆ Output Belt Conveyor takes the dried bentonite out of the rotary dryer.

◆ Electric Control Panel is used to control all the machines inside the whole bentonite drying line.

Bentonite Dryer Capacity:

Bentonite Dryer by Sunco Machinery is specially designed according the features of bentonite such as initial moisture content and output moisture content needed, prefered fuel, input capacity, output capacity, etc.

The necessay infomration for designing the Bentonite Dryer Machine is as follows:

◆ What is the initial moisture content (%) of the wet bentonite which is ready to be dried by the Bentonite Dryer ?

◆ What is the output moisture content (%) of the dried bentonite needed ?

◆ How many tons wet bentonite is needed to be dried per hour ?

◆ What kind of fuel is prepfered to be used such as natural gas, diesel, waste wood, wood chips, etc ?
