FC-300型风动碎石冲击器是1981年12月由冶金部在北京铁矿鉴定定型的。它是由东北工学院、北京铁矿、辽宁北台钢铁厂共同研制的 SFS-300型悬吊式风动碎石机上的工作机构。鉴定会认为,碎石机“具有破碎能力大、适应性强、参数基本合理、结构可靠、性能稳定、生产效率高等优点”。本文仅就这台高能量风动碎石冲击器的研制方法加以论述。
FC-300-type pneumatic stone impactor in December 1981 by the Ministry of Metallurgy in Beijing iron ore identification stereotypes. It is by the Northeast Institute of Technology, Beijing Iron Mine, Liaoning Iron and Steel Plant jointly developed by North Taiwan SFS-300-type pendant-type pneumatic stone work on the mechanism. Identification will think that lithotripsy “crushing capacity, adaptability, the basic parameters of reasonable, reliable structure, stable performance, high production efficiency.” This article discusses only the development of this high-energy pneumatic breaker.
