Rotary kiln is one of the widely used thermal non-ferrous metallurgy factory equipment. Non-ferrous metallurgy process, all kinds of materials such as concentration, flux, solid fuels, all kinds of slag material and so on, often need to dry the ability after charging, dry material is the main equipment of rotary kiln. Rotary kiln or some specific smelting non-ferrous metallurgy process of the main equipment, as some difficult choose oxide copper used in the process of segregation of segregation rotary kiln; Sand baked zinc leaching residue of zinc, lead, tonggu slag, the wind in the rotary kiln.When the cement kiln thermal changes in the system, its temperature change is not large, thus reducing the tire temperature stress. cement kiln operation, the wheel with a cement kiln to produce relative sliding along the weeks to will cause wear and tear, when the plate play a role in the protection of the cement kiln. In order to ensure the outer circle of the tire and cement kiln design gap, and their mutual good contact with the wheel with the inner circle and the plate required to be machined. In the cement kiln tire on both sides, to baffle or retaining ring to limit the wheel with a traverse along the cement kiln axial. Round with a box; the cross section of a hollow box-shaped, running, cooling conditions. However, due to the cross-section of complex shape, casting, easy to expand and contract process cracks defects. Sometimes casting stress can cause the tire rupture. This cement kiln tire than the rectangle round with the thicker, the temperature difference between inside and outside surface temperature stress. In the same weight, the cement kiln box-shaped wheel with rigidity is much greater than the rectangular tire, so the rational use of materials. But special attention should be follow the principle of uniform cooling rate of casting various parts of the design of cement kiln tire structure, reducing the casting stress. From the reinforcement of the role of the cement kiln, the priority should be given the box-shaped wheel with the same time, as far as possible to simplify the structure, ease of manufacturing.cement making machinery: http://www.bestjawcrusher.com/news/242.html
