一种新型供砂装置

A New Sand Feeding Device

在使用树脂砂造型工艺的生产中,经常遇到一些铸件的造型工艺要求面砂使用新砂,中间填充层和外层背砂使用混合砂或再生砂的造型工艺。通过对单一模式供砂方式的连续式混砂机供砂装置进行改造,很好的解决了这一问题。

Rebuilding of a sand feeding device for continuous sand mixer has properly solved the problem that different molding sand such as new sand and mixed sand or reclaimed sand would be needed for different sand layer of some molding technology of certain castings in resin bonded sand molding.
