目前钙镁磷肥存在的问题是:单耗高,炉型不统一,粉矿难以利用,“三废”污染严重,劳动强度大。提出高炉节能,干磨系统节能,钙镁磷肥污水封闭循环,生产多元素钙镁磷肥等技改具体措施,达到降低能耗,消除“三废”污染,提高机械化、自动化水平,提高企业经济效益的目的。 The current problems of calcium magnesium phosphate is: high consumption, furnace is not uniform, hard to use powder, “three wastes” serious pollution, labor-intensive. Proposed blast furnace energy saving, energy-saving dry grinding system, closed cycle calcium and magnesium phosphate sewage, the production of multi-element calcium magnesium phosphate and other technical measures to reduce energy consumption, eliminate “three wastes” pollution, improve mechanization, automation, and improve economic efficiency purpose.
