【摘要】 原铸造用砂精再生机存在砂子堆积堵塞,易损件磨损快,砂子分离不彻底等问题,现通过增大落砂的间隙,易损件抛砂盘和上下摩擦环选用耐磨材料HCr-F及将进风口由环形改为梅花形,以增大进风量等,不仅解决了上述问题,而且生产效率及再生回收率提高,分别为8m3/h,85％,使用寿命延长.更多还原

【Abstract】 There are some problems -the amassment and jam of a sand, and the fast tear of vulnerable parts, and halfway separation of a sand in the original reclaiming equipment with cleaning foundry sand. Now with increasing the clearance of the falling sand, and using the wear resisting material HCr-F in the casting pan and the top and bottom friction rings, and changing the air entrance from a annularity into a quincunx to enlarge the air intake, etc. , the above problems not only have been resolved but also the productivity effect and the re-claimming rate have been raised and is 8 m3/h and 85% respectively. Its lifetime is prolonged.更多还原
