黑色金属和有色金属、水泥生熟料、许多非金属矿物和各种磨料的磨矿费用可与采矿费用相比,因而此种磨矿过程存在着一定的问题。上述物料的特点是强度高、耐磨性强,而其磨矿势必要消耗大量的电能、钢材和人力。1980年,苏联各种物料的磨矿总电耗达410亿度,约为全国发电量的4％。根据塔加特关系式计算出的磨矿费用为每年十亿卢布以上。该关系式如下: 磨矿费用=(?)式中 R(?)=2.5——该系数考虑了生产费用和折旧费;A——耗电量;(?)——电价在现代碎磨技术(破碎机与磨矿机)中,采用钢介质和电力驱动装置的磨矿机占主导地位。研究证实,这类磨机已形成了一个完 The grinding costs of ferrous and non-ferrous metals, cement raw materials, many non-metallic minerals and various abrasives can be compared with the cost of mining and there are certain problems with this grinding process. The above material is characterized by high strength, wear resistance, and its grinding potential will consume a large amount of electricity, steel and manpower. In 1980, the total power consumption of all kinds of Soviet Union grinding materials reached 41 billion degrees, about 4% of the national power generation. Grinding costs calculated according to Tagat relations are more than 1 billion rubles per year. The relationship is as follows: Grinding costs = (?) Where R (?) = 2.5 - This factor takes into account production costs and depreciation charges; A - power consumption; (Crushers and mills), mills with steel media and electric drives dominate. Research confirmed that such mills have formed a finish
