Waelz Kiln For ZnO Recycling Equipment Zinc Dust Rotary EAF Slag

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                                                                                    

The rotary kiln from china professional manufacture Derui 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.

The structure characteristic of rotary kiln

1. The rotary calcining kiln shell design fully take into consideration of the corner at shell flexible supporting to extend the lifetime of refractory bricks and castings.
2. Adopt supporting roller bearing with big diameter and small ratio between length and diameter to improve the reliability. The bearing is automatic self-sligning bearing.
3. The better sealing effect of new type open gear hood sealing type.
4. The spring lamination overlying type lexible sealing, double layer spring lamination sealing increase the heat insulation layer to improve the reliability and lifetime.
