Introduction of Ceramsite sand
Ceramsite sand or ceramic sand, the oil support agent, is also called the oil proppant.
The main raw material for Ceramsite sand: bauxite, manganese powder, feed back etc.
Process flow of Ceramsite sand rotary kiln
1. Crushing and milling: After two-stage crushing by jaw crusher and hammer crusher, it enters the ball mill to grind the powder. Generally, a drying and grinding ball mill is used, and a high-efficiency classifier is used to form a closed-circuit system to increase milling output. The hot air for drying can use the waste gas of the rotary kiln to improve the utilization of waste heat.
2. Ball making: store the ground raw meal powder in the material tank, and enter into the ball disc through the metering screw. The ball disc can be made into various specifications of material balls during the rotation process. After the material balls are discharged into the ball disc It enters the drum screen through the belt conveyor, the qualified ones enter the rotary kiln for calcination, and the unqualified ones return to continue granulation.
3. Calcining: Qualified pellets enter a rotary kiln with a certain slope. After a high temperature of about 1360℃, the pellets are calcined into high-strength ceramsite sand.
4. Finished product cooling: The ceramsite sand is generally cooled by a drum cooler, which is simple and reliable. The secondary air of the cooler can be completely fed into the kiln. The temperature of the cooled ceramsite sand is less than 60℃. After cooling, it enters the drum screen and can be divided into multiple particle size grades as required.
Type I 0.45-0.9mm (20-40 mesh) high strength medium density
Type II 0.9-1.25mm (16-20 mesh) --------
Type III 1.0-1.7mm (12-18 mesh) -----
