1977年,选矿从研究到生产的各个领域的活动都着重于节能和环境保护。选厂布置南非两个金刚石矿的破碎和选厂,采用了辐射状布置。据称,与传统的直线布置相比,节省了劳力,提高了管理效率,改善了设备维修和利用率。环境 1972至1975年间,美国铜工业投资的40％、铅锌工业投资的28％用在防治污染方面。自动化价格低、可靠性高的小型计算机的应用增多。计算机控制的磨矿回路日益普遍,破碎流程的自动控制也越来越受到重
In 1977, activities ranging from research to production were focused on energy conservation and environmental protection. Selection of plant layout South Africa two diamond mine crushing and dressing plant, using a radial arrangement. Allegedly, compared with the traditional linear layout, saving labor, improve management efficiency and improve equipment maintenance and utilization. Environment From 1972 to 1975, 40% of U.S. copper industry investment and 28% of lead and zinc industry investment were used in pollution prevention and control. Automated low-cost, high-reliability small computer applications. Computer-controlled grinding circuits are increasingly common and the automatic control of the crushing process is also more and more important
