我院研制的GS1000×2000煤用概率分级筛,经历一年多时间,全国已有七省十四个局矿使用,订购概率分级筛60余台。使用较早的阜新、大同、徐州、晋城等局矿,已取得明显经济效益。阜新矿务局五龙矿选煤厂,82年3月使用概率筛以来,平均每年增收100多万元。徐州矿务局权台矿,83年改用概率分级筛,全年扭亏增盈290多万元。晋城矿务局古书院矿,83年开始使用概率筛,全年可增收370多万元。
Our hospital developed GS1000 × 2000 coal with probability grading sieve, experienced more than a year, the country has seven provinces Bureau of Bureau of mine use, ordering more than 60 sets of grading sieve. The use of earlier Fuxin, Datong, Xuzhou, Jincheng and other bureau mines, has achieved significant economic benefits. Wulong Coal Preparation Plant, Fuxin Mining Bureau, since March of 1982, has used the probabilistic screen to increase its average annual revenue by more than 1 million yuan. Mining Bureau of Xuzhou Datong, 83 years with probability grading screen, turnaround losses throughout the year by more than 290 million. Ancient Academy of Mining Jincheng Mining, 83 years began to use the probability screen, an annual increase of more than 370 million.
