Stable Running Bauxite Rotary Kiln 48-1000T/D Simple Flexible Operation
Whole Plant of Bauxite Rotary Kiln Sale:
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. ZK 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.
Bauxite Rotary Kiln Structure:
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.
5. The kiln head and tail sealing adopt new technology of heat resistant steel scale, which instead of labyrinth sealing, not only reduce the air leakage of kiln head and tail, but also durable and easy replacement with low maintenance charge.
Bauxite Rotary Kiln Our Advantages:
1. Bauxite rotary kiln adopts adjustable speed driving with high efficient and low power consumption.
2. 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.
Bauxite Rotary Kiln Working Priciple:
The rotary kiln from china professional manufacture Hongji Group Machinery is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly around its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, the materials gradually move down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or 'firing pipe') which acts like a large burner. The fuel may be gas, oil or pulverized coal.
