rotary coal calcination kiln
1. Main characteristics of the bauxite rotary kiln
1).The cement rotary kiln applied to roast active lime and dolomite which are commonly used in steel factories and ferroalloy factories.
2).The metallurgy chemical cement rotary kiln is mainly used for magnetized roasting of lean iron ore and oxidizing roasting of chrome ore and nickele ore etc in steel plants. In refractory plants, this rotary kiln is mainly used for roasting clinker and aluminum hydroxide.When used in chemical industry, it is mainly used for roasting chrome ores and chrome powders and more.
3).The cement rotary kiln is primarily used for caining cement cliner, It can be divided into dry process rotary kilns and wet process rotary kilns.

2. Features of bauxite rotary kiln :
1). Support device: advanced shaft structure, has automatic temperature measurement and
electrical heating device ,meanwhile you can choose liquidity support .
2). Catch wheel : mechanical wheel and hydraulic pressure
3). Gearing: single driver or double driver. Control the revolution by YZD, DC motor and
frequency variable motor. Be reliable , energy-saving, and efficient.
4). Cylinder tyre bolster: bolster has three types: fixed type, adjustable type and floating type. The structure is simple,maintenance and replacement are convenient without hurting the cylinder.
5). Sealing equipment: there are many different design of sealing style for choice according to kiln models, including air cylinder edge sealing, spring edge sealing , graphite block sealing and combination for above. The feather is adaptive for cylinder rotating and swing.
