在我国南方,由于雨水较多,雨季较长和矿石严重风化,很多矿山开采出来的矿石中含泥多水分大,给选矿前的破碎筛分系统生产带来很大困难,并严重影响选矿厂处理能力的发挥。为了解决泥矿堵塞问题,通常在设计中考虑增加洗矿工艺的技术措施,脱除其中的泥砂杂质,但在目前生产中洗矿工艺流程复杂,生产管理不便,洗矿效果不够理想。近十多年来,自磨技术在我国得到广泛重视,特别是无产阶级文化大革命以来有了新的发展。尤其是采用粗破碎—湿式自磨机处理江南地区含泥矿石,比破碎—洗矿工艺流程显示 In the south of our country, due to the heavy rainfall, the long rainy season and the serious weathering of the ore, many mines containing large amounts of mud in the mined ore have great difficulties in the production of the crushing and screening system before the dressing and seriously affect the quality of the concentrator Ability to play. In order to solve the blockage of mud and mud, the technical measures to increase the washing process are usually taken into consideration in the design to remove the mud and sand impurities therein. However, the current production process involves complicated washing processes, inconvenient production management and unsatisfactory washing results. In the past decade or so, self-wear technology has gained widespread attention in our country, especially since the Great Proletarian Cultural Revolution. In particular, the coarse crushing-wet self-grinding machine is used to treat the muddy ore in the southern part of the country, which is better than the crushing-washing process
