由焦作群英机械厂研制的PE-250A颚式破碎机,经两年的工业运行,并经“中国矿山机械质量监督检测中心”和“机电部中小型破碎机质量监督检测中心”两次性能测试,证明达到国内先进水平,最近在焦作市通过技术鉴定。目前,国内生产的颚式破碎机,大都是1962年定型的产品,性能差,结构陈旧,20多年一个样,与国际八十年代水平相比差距较大。在采用国际标准中,焦作群英机械厂在分析市场,收集信息,了解行情,确定方案中瞄准国际八十年代的新水平,对产品进行更新换代。在武汉钢铁学院对破碎机进
The Jaw Crusher PE-250A developed by Jiaozuo Qunying Machinery Factory has been tested for two times by two years of industrial operation and passed the performance tests of “China Mining Machinery Quality Supervision and Testing Center” and “Mechanical and Electrical Department Small and Medium Crusher Quality Supervision and Inspection Center” , Proved to reach the advanced domestic level, recently passed the technical appraisal in Jiaozuo City. At present, the domestic production of jaw crusher, mostly stereotyped products in 1962, poor performance, outdated structure, a sample of more than 20 years, compared with the international level of the 1980s, the gap between the larger. In the adoption of international standards, Jiaozuo Qunying Machinery Factory in the analysis of the market, collect information, understand the market, determine the program aimed at a new level in the 1980s, the product replacement. In Wuhan Iron and Steel Institute crusher into
