Zinc Oxide Rotary Kiln
Zinc oxide is used in rubber industry, mainly used for natural rubber, latex and rubber active agent compound using. Secondly it is used as intensifier and coloring agent. It is widely used in coatings, printing ink, paper making, medicine, chemical industry, ceramic, and glass, match, cable and cosmetics industries.
Features and usages of zinc oxide rotary kiln
1,Making the rubber more abrasion resistance,tear resistance ,more flexible;
2,Reducing the cost of production,stable curing performance;
3,Production can be widely used in paint,ink,Qibu shading,printing the dye;
4,As the raw materials of rubber adhesive plaster in the pharmaceutical industry,also used to paint.
Process of zinc oxide rotary kiln
First, crushing and milling
The dry crude material will be crushed and milled first.
After milling, the materials would enter the kiln outlet( high end of the cylinder) through the preheater, and then are fed into the kiln by the tremie pipe. Meanwhile, The heating source is sprayed into kiln by burner barrel in the head of the kiln. Due to the inclination of the cylinder and slow rotation of the cylinder, the materials roll in hoop direction. During this process, They will be calicinated, reacted, decomposed in succession through the calcinating section, reaction section, decomposition section,
Then the materials are discharged from the head of the kiln and enter the cooling device and be cooled.
At last, screening
Then they will go through the screens and final products will be conveyed to the yard. The big size materials will be sent back and processed.
