OUTPUT

Capacity:10000-30000(t/a)

Application: Oil Industry

Main Materials: bauxite,kaolin

Main Equipment: Ball Mill,Oil fracturing proppant

OUR ADVANTAGE

1. Energy Saving

The refractory lining of the rotary kiln consists of the outer insulation made of light refractory brick and inner compound refractory bricks. Such kind of lining will reduce the heat emission on the shell surface of the rotary kiln as much as possible. The pre-heater at the end of the rotary kiln will recycle the heat to preheat the material and save fuel by 40% and increase the output by 30%.

2. Low consumption

Rotary cooler at the discharge end of rotary kiln recycles the heat of Oil fracturing proppant which is discharged from the rotary kiln, and will preheat the secondary air up to 500℃.

3. Environmental protection

Two phases of dust collection including cyclone filter and bag filter, will control the dust emission below the limitation of the national standard.

4. High degree of automation

PLC control system improve the job efficiency.

PROCESS

Bauxite will be firstly crushed by jaw crusher and hammer crusher and then it will be conveyed to batching silo.

After batching with other material, materials will be sent to ball mill and grinded into powder. Classifier will be used after ball mill for size grading. Here raw material will be sent to silo again.
Bauxite will be firstly crushed by jaw crusher and hammer crusher and then it will be conveyed to batching silo.

After batching with other material, materials will be sent to ball mill and grinded into powder. Classifier will be used after ball mill for size grading. Here raw material will be sent to silo again.

Then raw material will go to granulator and will be made into different size pellets. Pellets will be sent to screening equipment. Qualified size pellets will be conveyed to rotary kiln for calcination. Oversize pellets will be sent back for grinding.

After pellets calcined in rotary kiln, we get qualified product ceramic sand. At last, ceramic will go to cooler for cooling. And will go to screen to get different size oil fracturing proppant and will be packed in ton bag. The production process ends.
