【本刊讯】粉碎“四人帮”,科技大解放。在《中共中央关于召开全国科学大会的通知》的鼓舞下,阳泉矿务局、平顶山选煤设计研究所和洛阳矿山机械研究所共同组成的等厚筛分试验小组的全体同志,加快步伐,大力协同,于国庆28周年前夕,在阳泉三矿获得了等厚筛分试验的成功,在水份为5.8%条件下,取得了13毫米筛分单位面积处理量达20吨/时米~2(普通筛分法一般为10吨/时米~2)、筛分效率97%的良好成果,填补了我国筛分技术方面的一项空白,为解决国民经济急需的13～25毫米级块煤的技术攻关打下基础。
【News】 smash the “gang of four,” the liberation of science and technology. Inspired by the “Notice of the Central Committee of the Communist Party of China on Holding a National Science Conference,” all the comrades in the equal-thickness screening test group that is jointly formed by the Yangquan Mining Administration, Pingdingshan Coal Preparation Design Institute and Luoyang Mining Machinery Research Institute have stepped up their efforts and vigorously promoted Synergy. On the eve of the 28th anniversary of National Day, the success of the equal-thickness screening test was obtained at the Yangquan No.3 Mine. With the moisture content of 5.8%, the treatment capacity of 13 mm sieve per unit area reached 20 tons / Normal screening method is generally 10 tons / hour meter ~ 2), screening efficiency of 97% of the good results, to fill a gap in screening technology in our country, in order to solve the urgent need of the national economy of 13 to 25 millimeters of lump coal Technical research laid the foundation.
