长期来普遍认为铸工车间中件潮模砂与小件潮模砂合用一套砂处理系统是困难的,难以保证两种型砂质量。确实两种不同型砂合用一套砂处理系统,最大的问题是粗、细砂相混。无论粗砂进入细砂中,还是细砂进入粗砂中均要影响型砂的质量。因此以往铸工车间对中小件型砂处理总是采取两套砂处理系统,这样不仅使设备投资增加,场地利用率不高,而且不利于集中管理及 It has been generally accepted for a long time that it is difficult to use a set of sand treatment system for the middle piece of tide mold sand and small piece of tide mold sand in the foundry workshop. It is difficult to ensure the quality of the two types of sand. Indeed, two different types of sand combined with a sand processing system, the biggest problem is coarse, fine sand mixed. Whether coarse sand into the fine sand, or fine sand into the grit should affect the quality of sand. Therefore, in the past, the casting workshop always took two sets of sand treatment systems for small and medium-sized sand processing, which not only increased equipment investment and utilization rate of the site, but also detrimental to centralized management and
