前言近几年来,我国地方煤矿发展很快,从1981年开始以平均每年增长近800万吨的速度上升,1984年开始为3.9亿吨,占全国原煤产量的49.99%,1985年为4.5亿吨,占全国原煤产量的52.33%,在我国煤炭行业中占着相当重要的地位。另一方面,由于近期煤炭市场供需关系的变化、用煤行业调整及户用对煤质要求提高等原因,使不少地方煤矿出现原煤滞销和积压现象。因此,设计和建设小型简易选煤厂、加工厂,对地方煤矿的原煤进行小洗选,小加工,提高煤质,增加品种,扩大煤炭资源的综合利用,提高煤矿的经济效益具有了十分重要的现实意义。水介质旋流器是一种利用水作介质,在离心力场中进行分选的设备。它具有体积
Preface In recent years, the development of local coal mines in our country has been developing rapidly. Since 1981, the average annual increase of nearly 8 million tons has been rising from 390 million tons in 1984 to 49.99% of the total output of raw coal in the country and 450 million tons in 1985 Accounting for 52.33% of the country’s total output of raw coal, which occupies a very important position in China’s coal industry. On the other hand, due to the recent changes in the supply and demand in the coal market, adjustments in the coal industry and improvement in household requirements for coal quality, many local coal mines have caused the phenomenon of sluggish sales and backlogs of raw coal. Therefore, it is very important to design and construct small and simple coal preparation plant and processing plant to conduct small washing, small processing, improve coal quality, increase varieties, expand comprehensive utilization of coal resources and improve economic efficiency of coal mines in local coal mines The practical significance.
