我厂使用的φ1250×1250双转子反击式破碎机,是1971年9月25日正式投产的。从1972年算起,到1976年底运转了7398小时,破碎石灰石约77万吨。经过五年多的使用,我们厂破碎机岗位工人和技术人员,坚持唯物论和辩证法,在生产实践中,边实践,边认识,边改进,逐步地完善,目前对这台设备的技术性能,运转和操作规律有所掌握。现在台时产量已达到和超过设计水平。产品出口粒度基本满足一次入磨要求。我们认为,反击式破碎机与其他各种破碎机相比较,具有破碎比大,工艺布置短
I used φ1250 × 1250 double rotor counter-crusher, is the September 25, 1971 officially put into operation. From 1972 onwards, by the end of 1976, 7398 hours of operation, crushing limestone about 770000 tons. After more than five years of use, our factory workers and technicians in crusher posts adhere to materialism and dialectics. In practice, we practice, know, improve, and improve gradually. At present, the technical performance, Operating and operating rules have mastered. Now Taiwan production has reached and exceeded the design level. Export products to meet the basic particle size into a request. In our opinion, the impact crusher and all kinds of other crushers compared with the crushing ratio, short process layout
