Zinc Oxide Recycling Plant From EAF Dust Waelz Kiln

Product introduction and application

The rotary kiln produced has advanced structure. It can effectively improve preheating effect with its low resistance vertical preheater. After the material is preheated, the feeding decomposition rate can reach 20%-25%, thus can directly make use of 10-15mm fine fraction materials. The reliable airtight two-ends combination squama make the air leakage factor under 10%. The usage of compound refractory reduces radiation loss.Rotary kiln belongs to building material equipment, which can be divided into cement kiln,metallurgy chemical kiln and lime kiln according to different materials.

Working Principle of rotary kiln

The rotary kiln can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to the different materials processed. The cement kiln is mainly used to calcine cement clinker; In the process of non-ferrous and ferrous metallurgy, such as iron, aluminium, copper, zinc, stannum, nickel, wolfram, chromium, etc., the rotary kiln can be used to sinter and roast ore, concentrate, intermedium, etc.; The lime kiln is mainly used to calcine limestones.

Features of rotary kiln cement plant:
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.Kiln head hood: including stationary type and flexible type.
