国内外的研究和发展证明,共振筛是一种产量大、效率高、电耗小的先进设备,尤其以面积大、动平衡好、给基础的动力小而著称,因此在世界各国获得广泛应用。GS2—30型共振筛是我国自行设计制造的宽度最宽的大面积筛分设备,先后在抚顺西露天矿古城子选煤厂和平顶山田庄洗煤厂使用,至今已有四年了。实践证明,该设备作为原煤分级,洗煤脱介,脱水之用表现出产量大(544吨/时,田庄71年3月16日测),
Research and development at home and abroad have proved that the resonance sieve is an advanced equipment with large output, high efficiency and low power consumption. It is widely used in various countries in the world, especially because of its large area, good dynamic balance and small basic power. . GS2-30-type resonance sieve is designed and manufactured by China’s widest wide-area screening equipment, has in Fushun West opencast coal mine and the ancient coal pit factory Pingdingshan Tianzhuang use, has been for four years. Practice has proved that the equipment as raw coal classification, coal washing, dehydration with the use of large output (544 tons / h, Grange March 16, 71 measured)
