Ceramsite sand rotary kiln
The increasing demand for petroleum fracturing proppant products promotes the continuous development of each country’s petroleum fracturing proppant (ceramsite sand) industry, and the rotary kiln has been continuously optimized as key equipment for calcining ceramsite sand. The rotary kiln designed by our company for the needs of the petroleum fracturing proppant industry has the characteristics of strong calcination capacity, high thermal efficiency, and uniform products.
Ceramsite sand, also called fracturing proppant, is a kind of ceramic particle product with high fracturing strength. It is mainly used for downhole support in oil and gas fields to increase the output of oil, natural gas, coalbed methane, and shale gas. It is an environmentally friendly product. This product is made of high-quality bauxite and other raw materials that are sintered. It is a substitute for low- and medium-strength proppants such as natural quartz sand, glass balls, and metal balls and has a good effect on increasing oil and gas production.

Outstanding features of ceramsite sand rotary kiln
1. Rotary kiln drive adopts frequency conversion speed regulation, high efficiency and low power consumption;
2. Low fuel consumption per unit product and large production capacity;
3. Negative pressure operation, low dust pollution;
4. Stable mechanical performance, smooth transmission, easy control of calcination temperature.
Ceramsite sand rotary kiln working principle
The bauxite with a particle size of 300-500mm is crushed and sent to the fluidizing furnace dryer for drying, and then passes through the batching station with manganese powder and additives, and enters the grinding system with a vortex separator to prepare fine particles.
For the raw meal powder with a degree of 400 mesh or more, a new type of granulator is used to make the raw meal powder into pellets with a qualified particle size after adding water. The pellets enter the dryer at the end of the kiln, use the waste heat of the exhaust gas from the kiln tail to reduce the moisture of the pellets, and then enter the rotary kiln for calcination after screening.
The calcined ceramsite sand is cooled by a single cooler and then sieved through a cylindrical sieve. The qualified and different particle sizes are packaged separately and then shipped out. The unqualified pellets are returned to the grinding system.
