Ceramic Sand and Production Equipments

Ceramic sand, also called fracturing support agent, is a kind of ceramic particles with a very high fracturing strength and is mainly used for oil field support to increase oil and gas production, it is an environmentally friendly products. Ceramic sand sintered by ceramics with high quality bauxite and other raw materials is a natural alternatives of quartz sand, glass beads, metal ball, etc, low strength proppant alternatives. It has good effects on increasing oil and gas production. Ceramic sand production process and the ceramic sand production equipments are complex.
Ceramsite sand production equipments mainly include ceramsite sand ball mill, rotary kiln for ceramic sand, ceramsite sand granulator, ceramsite sand granulator ceramsite sand screening equipment and so on. Henan Zhengzhou Mining Machinery Co., Ltd. provide full range of ceramic sand production technology services, quality and excellent ceramic sand production equipment, advanced ceramic sand production process.

At present, most industrial rotary kilns are used in ceramic production process, the cylinder shaped main kiln body is placed on the roller with 3^。angle with the level.
Material get into the kiln from the high end. the materials drop down from above (kiln) to lower (kiln) and come out from the kiln head.
High pressure air fan will spray pulverized coal (or natural gas and other fuel) into the kiln and make it fully burn. the heat produced by the material physical and chemical changes can result in the expansion of the phenomenon and the ceramsite sand is perfomed after being cooled.
Ceramic sand has the following characteristics:
1 Enough compressive strength and wear resistance ability, ability to withstand when injected into the strong pressure and friction, and effectively support the artificial fracture.
2 Particle relative density is low, easy to pump into the underground.
3 The particle diameter is in accordance with the design requirements of different oil wells, generally 0.4-0.8mm, roundness and roundness is greater than 0.9, and the particle is uniform, surface is smooth, the turbidity value is less than 100 degrees, high flow conductivity.
4 Particles have no chemical reaction with the fracturing fluid and reservoir fluid in the temperature 200℃, the acid solubility of the maximum allowable value should be less than 7%.
Ceramic sand is not only with high density, good ball, corrosion resistance, high temperature resistance, high pressure resistance characteristics but also the cost can be well controlled, so it is more and more widely used in oil and gas fields. Practice has proved that the use of ceramic sand can increase the production of oil wells 30-50%.
