(本刊讯)今年5月上旬,河南省平顶山市举行30 M~2共振筛评议会。与会同志对平顶山市田庄洗煤厂正在使用的我国洗煤工业最大的筛分机械——30 M~2共振筛进行了评议。认为它具有产量大、效率高、能耗低、动平衡好、传给基础的动力小等优点,但由于它筛面面积大、跨距宽,工作条件繁重等原因,运转以来也存在不少问题。与会同志充分肯定了该攻关小组长期以来在侧试,分析计算,试验研究,理论探讨等方面做的大量工作,认为基本找到了问题的桔梗所在,采取了切实可行的措施,从而使设备在结构强度,调整维修等方面,
(Ben Kanxun) In early May this year, Pingdingshan City, Henan Province held 30 M ~ 2 Resonance Screening Council. Participating comrades at Pingdingshan Tianzhuang coal washing plant is being used in China’s coal washing industry’s largest screening machinery - 30 M ~ 2 Resonance Screen were reviewed. It is considered as having the advantages of large output, high efficiency, low energy consumption, good dynamic balance and low power transmission to the foundation. However, due to its large screen area, wide span, heavy working conditions and many other reasons, problem. The comrades at the conference fully affirmed that the research team has done a great deal of work for a long time in aspects such as side examination, analysis and calculation, experimental research and theoretical discussion, and considered that the root of the bellflower where the problem was basically found was taken and practical measures were taken to make the equipment in the structure Strength, adjustment and maintenance, etc.,
