Rotary kiln information

Rotary kiln is the calcining kiln (commonly known as rotary kiln), which belongs to the device class materials. Kiln according to different materials can be divided into cement kiln, metallurgy chemical kiln and lime kiln. Cement kiln is mainly used for calcining cement clinker production of dry and wet cement kiln cement kiln production of two categories. Metallurgy chemical kiln is mainly used in metallurgical industry, steel plants depleted iron ore magnetic roasting; chromium, nickel, iron ore roasting; high alumina refractory bauxite ore roasting plant and aluminum roasting clinker, aluminum hydroxide; chemical chromium ore roasting and chrome ore and other minerals. Lime kiln (ie active lime) for firing steel mills, ferroalloy plant with active lime and light burned dolomite.

Rotary kiln application

Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry; for calcimine of calotte and aluminum hydroxide in aluminum manufacturer; for claiming of chrome sand ore and chrome powder ore in chemical plant.

Working principle of rotary coal dryer kiln:

1) With a certain slope to the level, the whole kiln body is supported by rollers and fitted with thrust rollers to control up and down movement of the kiln body.

2) Besides main driving unit for driving system, it is also fitted with the auxiliary driving unit so as to ensure the kiln body still can rotating when the main motor is powered off and prevent it from deforming.

3) The kiln head adopts housing type sealing and kiln rear uses axial contact sealing unit so that reliability of sealing could be ensured.

Rotary Kiln Features:

1. Support device: advanced shaft structure, automatic temperature measuring device and electrical heating,.

2. Catch wheel: including two kinds mechanical wheel and hydraulic pressure

3. Gears:  single or double. Control the rotating speed by buncher, DE machine and frequency variable motor. Be reliable, energy-saving, and efficient.

4. Cylinder tyre bolster: lower bolster has three types: fixed, zoom and floating. The structure is simple, replacement is convenient and won't hurt cylinder.

5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. 

6. Kiln head hood:  including stationary type and flexible type.
