Crush the zinc charging and the coke coal into powder lot less than 40%
Mixed the zinc charging with the coke coal pro rate of 0.30 to 1.35 evenly and make the mixture into granule with diameter being 8 to 15mm
In the end, put the granule into the brick kiln to smelt and produce zinc oxide
This techniques greatly saves the coke or fire coal
The product gained by smelting is of fine quality and high productivity
