Process introduction:

Ceramic sand is a kind of products of ceramic particle , which has a high fracturing intensity ,mainly used for oilfield as downhole proppant , The usage is to increase the output of oil and gas. So ceramic sand is a kind of green and environmental protection products .

Ceramic sand made of high quality bauxite and other additive material, granulating and calcining to increase the strength and density. It’s a substitute of natural quartz sand, glass sand, metallic sand and other low intensity proppant ,Ceramic sand is the best proppant to increasing oil and natural gas output.

In brief, the process of manufacturing ceramic sand is crushing→dosing→grinding →granulating→calcining cooling →screening packing .. Following is the description ceramic sand process:

1.crushing

The size of bauxite from mine is around 300~500mm, low moisture, After two-stage crushing which is composed by Jaw crusher and hammer crusher, the size of bauxite will be around 25mm.

2. Dosing

3. Grinding

In grinding process ,the main equipment is ball mill and separator to make a close-circuit grinding system .The granulator required the material size will be lower than 300mesh .

4. Granulator

The granulator system is totally automatic, continuously, matching with bag-type dust collector, can purification the exhaust air.

5.Calcining

Raw ceramic sand be calcined in rotary kiln , with the revolution and slope of rotary kiln, calcined ceramic sand move toward to the kiln head, meanwhile, pulverized coal spray into the kiln burner from kiln head, raw ceramic sand will be calcined into ceramic sand with high intensity in the rotary kiln.

6. Pulverized coal preparation

Pulverized coal preparation use ball mill or vertical mill, which can drying the coal with hot wind from kiln hoodsl. Use separator can adjust the fineness of pulverized coal at will; it provides sufficient conditions for full burning of pulverized coal.

7.Fineshed product cooling

8.Screening

9.Packing.
