Ceramic sand is a ceramic particle product with high fracture strength, mainly used for oil well supported in order to increase oil and gas production, an environmentally friendly product. Ceramic sand processing needs through the rotary kiln calcination, while using rotary kiln ceramic sand is very strict when raw. Mined bauxite, fragmentation is generally about 300 ~ 500mm, containing a small amount of water. Generally use jaw crusher and hammer crusher crushing system consisting of two, will control the particle size ≤ 8mm. Ceramic, is generally used to replace concrete, gravel and pebbles, is the use of various types of clay, slate, shale, coal gangue, and industrial solid waste and other raw materials, through the ceramic sintering. At present, China ceramic production equipment are used in industrial kiln. Cylindrical main body and the kiln level was about 3 ° inclination placed in the care roll on. Material into the kiln at the high end of the kiln rotary movement to do under the influence of material from tumbles to a low place, while at the kiln, high pressure air pulverized coal injected into the kiln, and to make it fully combustion heat generated by the materials from physical and chemical changes, resulting in swelling phenomenon, both for the ceramic after cooling. Ceramic sand production can be summarized as crushing, ingredients, grinding, ball, calcination, coal preparation, finished cooling, screening, packaging and other processes. Main raw material for high-grade bauxite. A cooler ceramic sand, can be directly transported to the multi-stage vibrating screen, press the requirements are divided into several size grades.
