一、现状 有色金属精矿产品运输途耗一直是困扰企业的难题,它不仅成为企业提高经济效益的重要影响因素,而且长期以来给国家造成严重的资源浪费,尤以矿山反响强烈。据凡口铅锌矿和株洲冶炼厂反映,1995年初他们曾做过105个火车车厢锌精矿运输对比统计试验,结果表明途耗占发货量的4.38％,单车厢途耗高达2.63吨,损失近百万元。事实说明,降低有色精矿运输途耗已成为有色行业节能降耗的一项重要措施。 针对以上情况,有色标准所以中色标所字(1998)第21号发出《关于调查有色精矿产品运输途耗的通知》,对行业内部的相关企业进行函调,主要内容包括:选矿工艺、精矿粒度、脱水方式、装卸时水份含量范围、发货标志、运输方式、运输里程、包装方式、计量方式和误差、途耗状况以及其中有关的途耗因素等。
First, the status quo Non-ferrous metal concentrate product transportation has always been troublesome business problems, it not only become an important factor to improve economic efficiency, but also for a long time to the country caused serious waste of resources, especially in the strong reaction of mines. According to Fankou Lead-Zinc Mine and Zhuzhou Smelter, in early 1995 they have done 105 railway wagons zinc concentrate transport comparative statistical tests showed that the transit consumption accounted for 4.38% of the shipments, single-car journey up to 2.63 tons, Loss of nearly one million yuan. Facts have proved that reducing the consumption of colored concentrate transport has become a non-ferrous industry, energy saving an important measure. In view of the above, the non-ferrous metals standard (1998) No.21 issued the Circular on Investigating the Transit Consumption of Nonferrous Concentrate Products, and sent letters to relevant enterprises within the industry. The main contents include: beneficiation process, Concentrate particle size, dehydration, loading and unloading moisture content range, shipping mark, mode of transport, transport mileage, packaging, measurement methods and errors, consumption situation and the consumption of the relevant factors and so on.
