Detailed introduction


In order to satisfy the domestic petroleum requirement, the petroleum exploitation industry develops rapidly, the related product also expanding rapidly. Hence, it promotes Chinese oil fracturing proppant industry continues development, and rotary kiln is the critical equipment for the oil fracturing proppant calcination.


Bauxite rotary kiln is constantly optimize after discuss with many senior experts and refer experiences for many years. At present, ZK designed a series of oil fracturing proppant rotary kiln according to the industry demand.

1. Bauxite rotary kiln adopts adjustable speed driving with high efficient and low power consumption.

2. Multiple fuels: gas, fuel oil and coal powder. The fuel consumption of unit product is low and large capacity.

3. The layout of system equipment is compact and simple structure, the maintenance is convenient with light weight and low investment for civil construction.

4. Easy operation and durable, less worker, reliable product process.

Working Principle

1. The rotary kiln has 2 to 4 supporting points (most of kiln has 3 points), which is ensure the support roller upper plane and tyre contact surface is parallel to the shell axis. There is a gap between tyre and shell which designed according to the expansion rate, then it guarantee to strengthen the shell by tight on the shell after thermal expansion.

2. The support device adopt rolling bearing to simplify the structure of support roller bearing, then it can reduce the power consumption during the kiln process and also improve the maintenance.

3. The driving system adopts adjustable motor with large scale, stable running and easy maintenance. The rotary kiln set a slow disk kiln structure, which is composed of diesel engine and reducer etc. It can running under power failure and convenient for kiln maintenance, the operation also simple and flexible.

4. The mechanical thrust roller and hydraulic roller are select by kiln model, the hydraulic thrust roller adopt domestic advanced technology of accurate plunger pump and speed control valve etc.
