2ZKB3070大型双层直线振动筛最近由鞍山矿山机械总厂研制成功。该筛机吸收了苏联和美国振动筛的先进技术,广泛采用了复合弹簧、环槽冷铆、双电机自同步和密封振动器新结构。该机具有结构合理、工艺参数先进、运行平稳、生产能力大、噪声低、故障少和维修方便等特点。填补了我国选煤行业大型筛机的空白(工作面积为22.24m~2),结束了该类筛机长期依赖进口的局面,并于1991年7月在鞍山通过了省级鉴定。 2ZKB3070 large double linear vibrating screen recently developed by Anshan Mining Machinery Plant. The screen machine absorbs the advanced technology of the Soviet Union and the United States shale shaker, widely used composite springs, cold ring riveting, self-synchronous dual-motor and sealed vibrator new structure. The aircraft has a reasonable structure, advanced process parameters, stable operation, large production capacity, low noise, fewer faults and easy maintenance features. It filled up the blank of the large screen machine in China’s coal preparation industry (working area is 22.24m ~ 2), ended the long-term dependence on the import of such screening machines and passed the provincial appraisal in Anshan in July 1991.
