云南第一轻工机械厂铸造车间,过去一直沿用老式的往复式筛砂机。为了提高生产效率,曾考虑采用滚筒筛或摆动筛,但这些筛砂机在生产效率、使用寿命以及消除噪声等方面都存在一定的问题。近年来该厂经过反复试验,制成一种双曲轴回旋式筛砂机(如图所示)。这种筛砂机生产效率高,而且无噪声,加 Yunnan First Light Industry Machinery Plant foundry, in the past has been using the old reciprocating sieve machine. In order to improve production efficiency, we have considered the use of trommel or swinging screen, but these screen sanding machine in the production efficiency, service life and to eliminate noise and so there are some problems. In recent years the plant after repeated testing, made of a double crankshaft rotary sand screening machine (as shown). This type of screen sand machine production efficiency, and no noise, plus
