摘要：
   铸造砂搅拌机通过封闭的纵向带式输送机来混合和配料二氧化硅或型砂及其添加剂，带有一个个的给料口，连接第一个配料装置，配料装置在带式输送机机制的顶部，底部有两个开口。 第一给料装置包括螺旋式输送机和一个挡砂板，这个挡砂板连接配料装置的最上端的给料口。 第一个漏斗含有石英砂和第二漏斗里的是型砂和添加剂，正对着第一个配料装置。 换向阀通向的每个次料斗底部的给料口，允许任意时刻任一一个料斗的砂子流过，还可以防止任一一个料斗的砂子流过。 该混砂机可包括多个配料装置，其中一些是装置连接从上游到下游的给料口，其他包括泵连接的多种液体通过专门的的高速搅拌机补给，材料在搅拌机中混合然后混合材料通过开口排除。

Abstract:
A foundry sand mixer for mixing and dispensing silica or green sand and their additives through the enclosed longitudinal belt conveyor mechanism having a plurality of openings in the top communicating with a first feeder disposed above the enclosed longitudinal belt conveyor mechanism and including a pair of openings in the bottom. The first feeder includes an auger-type conveyor and a sand weir communicating with the most upstream opening in the first feeder. A first hopper for containing silica sand and a second hopper for containing green sand are disposed over the first feeder. A selective valve is disposed at the bottom of each of the first and second hoppers permitting the flow of sand through only one of the hoppers at any time or preventing the flow of any sand from the hoppers. The mixer may include additional feeders, some of which are disposed above and downstream from the first feeder, and others including pumps are connected to a plurality of fluids that are fed through a constant speed mixer where the materials are mixed and the mixed materials delivered at a discharge opening.
