王集磷矿选矿厂原设计规模为年处理原矿150万t,分六个磨矿分级系列。系列生产能力为31.60t/h,最终产品浓度为25％(-200目占91％)。 在生产调试中,浓度和系列处理能力仅为22.20％和24.52t/h,导致药耗升高10％,单位能耗升高20％,较为严重地影响了 Wangji phosphate ore beneficiation plant was originally designed for the processing of 1.5 million tons of ore, divided into six grinding grading series. Series production capacity of 31.60t / h, the final product concentration of 25% (- 200 heads accounted for 91%). In the production commissioning, the concentration and series of processing capacity of only 22.20% and 24.52t / h, resulting in drug consumption increased by 10%, unit energy consumption increased by 20%, a more serious impact
