本机由浙江义乌矿机厂和江西冶金学院共同设计,由义乌矿机厂制造。1979年3月进行了鉴定。该机优点如下:1.产量高,单位功耗低。经对三种不同硬度的石灰石破碎试验,其产量达60吨/小时。产品粒度中≤15毫米的占95％以上。单位功耗为1.25千瓦/吨。2.产量、粒度与流程衔接。可以满足水泥、焦化、烧结和火电站的需要。3.锤头更换方便。平均更换一付锤头(48个)只需要二个人,半个班(4小时)时间。 This machine is designed by Zhejiang Yiwu Mining Machinery Factory and Jiangxi Metallurgical Institute and is made by Yiwu Mining Machinery Factory. March 1979 was identified. The advantages of this machine are as follows: 1. High output, low unit power consumption. After three different hardness of the limestone crushing test, the output reached 60 tons / hour. Product size ≤ 15 mm accounted for more than 95%. Unit power consumption of 1.25 kilowatts / ton. 2. Production, grain size and process convergence. Can meet the needs of cement, coking, sintering and thermal power plants. 3 hammer replacement easy. The average exchange of a hammer (48) only two people, half a class (4 hours) time.
