Palmer Mixer

Palmer Mixer

Spokane Industries has replaced an Omco batch mixer (50# batches) with a new continuous mixer that will enhance our coring abilities.  In light of the size of the castings we are making currently, the quality of the cores will improve dramatically.  With our previous sand system, we had to mix in 50# batches at a time, which can potentially create layers of sand that have subtle variations in strength.  With our new core system, we will have continuous feed and consistent sand pours that will eliminate this variable.

The new Palmer Mixer allows us to move more efficiently into the realm of a 2 sand feeding system that allows either silica sand or specialty sand.

Additionally, we are moving away from spraying the cores – which lacks consistency from operator to operator – to “flow coating” - which creates a more consistent wash coating and allows for greater material penetration.  These 2 processes are expected to greatly enhance our efficiencies and minimize scrap and waste.

With this new addition we are taking the opportunity to redesign the floor plan of the coring department, which will allow for less material handling, less wasted movement and greater productivity.
