1.Main characteristics of the mining rotary kiln

1).The mining rotary kilnapplied to roast active lime and dolomite which are commonly used in steel factories and ferroalloy factories.

2).The mining rotary kilnis 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).Themining rotary kilnis primarily used for caining cement cliner,It can be divided into dry process rotary kilns and wet process rotary kilns.

4).These new technologies provide our mining rotary kilnwith strong visual sense, convenient operation and reliable performance. They help stabilize thermal regulation and improve operation efficiency.

5).Comparing with other similar cement production equipment, the operation rate of our mining rotary kilnincreased by 10%, production increased by 5%-10% and heat consumption decreased by 15%.In order to meet customers' requirements, we also provide impact crusher, cone crusher, magnetic separator,flotation machine,ball mill and more.

2.Working Principle ofmining rotary 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.

3.Application ofmining rotary kiln

Mining rotary kilnis 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.
