Moving bed was adopted to realize grain yellow lead the technology and the depth of the irregular grain yellow lead dioxide oxidation and rapid cooling, production of electronic industrial granular lead oxide. Production equipment including light oil burner, oxidation moving bed, moving bed of cooling and bag dust collector and other equipment. Production capacity of 1100 ~ 1200 tons/month. Sealing run, gas solid countercurrent contact, product purity of more than the national standard requirements, lead dust from production environment and lead pollution of steam, realized the mechanization of lead oxide production, continuous and semi automatic. The technology by the expert appraisal committee of science and technology, jiangsu province, is a leading international level, has been applied to industrial production plant. Technical indicators: the purity of lead oxide 99.6-99.8%; Tons of products 12 kg of fuel, electricity 10 degrees, heat efficiency more than 70%. Application: apply the technology in the lead, barium salt, strontium salt and other salt used in the production of inorganic salt roasting.
