我国某新建的中型规模的黄金冶炼厂在1990年11月试用成功了浆式进料技术,使我国首次解决了炉料不经干燥即可进行沸腾焙烧。它可彻底改善加炉料工序的劳动条件,可省去干燥间的投资,并可节省大量的工业用煤。这次试用成功,说明可全部使用国内技术装备便可实现浆式进料。对于我国冶炼厂的焙烧工艺现代化有广泛的推广价值。 浆式进料是将-80目的含多金属硫精矿,浆化到浓度70％的矿浆,筛去杂物后用可调流量的软管泵扬至炉顶的分流器中,再经六条胶管自流下,用压力600kPa的压缩空气经喷嘴吹至焙烧炉的料面之上。炉温高低
China’s new medium-sized gold smelter in November 1990 successfully tested the slurry feed technology, so that for the first time in our country to solve the burden of boiling material can be roasted. It can completely improve the working conditions of the charging process, eliminating the need for investment in drying, and can save a lot of industrial coal. The successful trial, indicating that all can use domestic technology and equipment can be realized pulp feed. For our smelter baking process modernization has a wide range of promotional value. Slurry feed is the purpose of containing -80 purpose polymetallic sulfur concentrate, slurried to a concentration of 70% of the pulp, sieve to remove debris with adjustable flow of the hose pump to the top of the shunt, and then by the six Hose flow down, the pressure of 600kPa compressed air through the nozzle blown to the roaster above the surface.
