The tumbling and the stirring and agitation reduce the material to a pulverized form of fine particle size so that all of the contaminating chemicals may be reached and destroyed by the high temperature flame jets. Various fuel gases may be used depending on the heat producing capacity required under any particular circumstances, and the heat produced in successive longitudinally spaced zones of the kiln body may be independently controlled according to the heat requirements in each zone. The use of such materials as PCB, TNT, and solvents such as toluene, xylene, and trichloroethane in agricultural and industrial applications, is becoming more and more common, and often leads to the contamination thereby of soil or earth, which must then be classified as extremely hazardous material.
The cylinder of rotary calciner kiln is made up of rolled steel, and the refractory lining is designed for cylinder body, which is located in a pre-determined inclination with the horizontal line supported by two wheels.
One ring gear is fixed on the inner cylinder near the discharging part and spring plate, under which there is a pinion meshing. Rotary calciner kiln is widely used in roasting dolomite, kaolin, bauxite, refractory material, cement, limestone, titanium powder, alumina, mineral, activated carbon, coke, magnesia, zinc oxide, special cement, etc.
Rotary calciner kiln can be pided into cement kiln, metallurgy and chemical kiln, lime kiln, titanium dioxide calciner kiln and talc powder calciner kiln, and the cement kiln can be pided into dry tppe cement kiln and wet type cement kiln, which is mainly used for calcining cement clinker.
Metallurgy and chemical kiln is mainly used in magnetic roasting of iron ore in steel plant and metallurgical industry; oxidizing roasting of chrome, nickel and iron; roasting of high alumina of vanadium bauxite and aluminum clinker, aluminum hydroxide in refractory plant; roasting of chrome ore and chromium ore and other minerals in chemical plant.Rotation Kiln, Wholesale Various High Quality Rotation Kiln Products from Global Rotation Kiln Suppliers and Rotation Kiln Factory,Importer,Exporter at ph-vs.com MENU.

Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over °C, while the gas temperatures reach °C.
Coconut Shell Activated Carbon Rotation Kiln Active lime kiln is a type of rotary kiln and it is the main equipment used for calcining active lime. Active lime kiln has the advantages of simple structure, reliable operation and easy control of the production process.
Rotary kiln refers to rotary calcining kiln,mainly used for calcining calcium aluminate, limestone, bauxite, kaolin clay, gypsum ph-vs.com is widely used in the fields of building materials, metallurgy, chemical industry, environmental protection, etc.
Rotary Kilns—rotating industrial drying ovens—are used for a wide variety of applications including processing raw minerals and feedstocks as well as heat-treating hazardous wastes. They are particularly critical in the manufacture of Portland cement. Common Rotary Kiln Applications.
Proppant manufacturers use the rotating motion and high temperatures within rotary kilns to sinter proppant powder and form uniform ceramic beads.
Because high temperatures are necessary to properly calcine and harden ceramic proppants, the rotary kilns used to manufacture proppants are often refractory.
