Chemicals No. 1 of Chinalco Shandong Branch, on the basis of earnestly examining the market situation of chemical white alumina high fill, actively took measures to reduce production costs and continuously improve the market competitiveness of products. In recent days, the use of a vertical plate filter for the first time in the high-white filler production line has resulted in a significant reduction in consumption. The plant technicians, through careful analysis of the production process of high-white fillers, found that the previously used seed mobile discs consumed a large amount, causing high costs. To this end, the technical staff of the factory organized and targeted the control system of the plate equipment, and found a set of operating methods suitable for the product, so that the equipment was fully adapted to the high white filler production requirements of the plant. The vertical disc filter is used for the first time in the production of chemical alumina. It has the advantages of large single machine capacity, advanced performance and convenient operation, and it can meet the current production needs in terms of application functions. Since the system was put into use, the high-white filler production of water, electricity, gas and other key energy consumption indicators have dropped significantly, the decline rate reached 35%, 25% and 13%, plus the process advantages, each year to bring a direct economy to the plant Benefit 5 million yuan.
