Direct process zinc oxide production process?
The direct method is a method of manufacturing zinc oxide invented by the Americans.
The production method is to use the waste ash to remove the impurities to obtain the qualified zinc ash, and then add the qualified zinc ash to the coal and lime according to the technical requirements, mix and crush, and the crushed material is pressed by the briquetting machine, and the pressed zinc is pressed. The briquettes are piled up and dried; the dried coal balls are smelted with a zinc oxide furnace, and after reduction, oxidation and cooling, zinc oxide products are obtained. The content is 99 995. 98. 95 90. and many more. Mainly used in ceramics a little more
