Kiln body: Zinc oxide kiln body generally is welded (or riveted ) by 20 mm thick steel plate into a cylinder.
Rolling ring: Rolling ring is not directly covered on the kiln body, but mounted on the kiln body through the base plate, its function is to strengthen the zinc oxide rotary kiln body, meanwhile, it can transmit the weight of the cylinder to the thrust roller. For the zinc oxide rotary kiln which is used for the production of refractories, it normally has 5 to 8 rolling rings.
Support roller and support roller shaft: The support roller is mounted on the support roller shaft by means of a hot assembly, and the support roller shaft is mounted into two bearings which have bronze bushings. The water temperature used for bearing after cooling is not more than 25 degrees.
Catch roller : The catch roller is a limiting device that limits the position of the zinc oxide rotary kiln on the support roller, but it does not prevent the body from moving up and down.
Transmission device: Zinc oxide rotary kiln is generally used to drive the rotation of the gear
Working Principle of Zinc Oxid Rotary Kiln
Zinc oxide rotary kiln working principle is the whole process and principles of the calcined zinc, zinc-containing materials. Generally it adopts the zinc oxide rotary kiln to process of the zinc-containing filter cake. The zinc in the filter cake mainly exists in the form of zinc ferrite, oxide and sulfate. Under the high temperature in the rotary kiln, the zinc ferrite and solid carbon will produce the reaction for oxide-reduction, then it will get the zinc, at the same time lead and cadmium sulfate also be reduced, will volatilize in the form of sulfide and gold bucked out. The reduced and volatilized metal from the solid phase will be re-oxidation, and finally will be produced in the form of oxide.
Note: The amount of air into the zinc oxide rotary kiln should ensure that the flue gas has sufficient oxygen to re-oxidize all the metal vapor, sulfide and carbon monoxide. Increasing the amount of air in the zinc oxide rotary kiln will increase the recovery zone to the feed end. On the contrary reducing the amount of air, the reduction area is shortened and the starting section of the reduction zone extends toward the discharge end.
