连续式混砂机一机两用新工艺的应用

Application of New Two-duty Process for Continuous Muller

使用1台12 t/h连续式混砂机混制不同品质的两种树脂砂,即石英质树脂砂和铬铁矿树脂砂,替代通常使用2套设备才能完成的工作,选用碱酚醛树脂作粘结剂,通过按钮操作实现混制两种不同品质树脂砂的目的。此工艺的应用改变了以前1台混砂机只能混制同一品质树脂砂的传统观念。同时一机两用新工艺不仅操作方便,而且还可以降低设备投资成本,减少设备占用面积,具有极高的推广价值。

Two kinds of different quality resin-bonded sand （quartz resin sand and chromite resin sand） were mixed by a 12t/h continuous muller,which usually completed by two sets of equipments. Selecting alkaline phenolic resin as binder, two different quality resin sands were mixed by push-button control. The new two-duty process is simple, reduces the equipment investment costs and occupied area, changes traditional view that the sand muller only mix one resin sand and have high promotive value.
