Four Element Primary Mix
Binder(s) and catalyst are mixed separately by primary mix screws consisting of a series of paddle and cam blades to move the sand forward, blend it with binder and control build-up on the trough walls. Cleats direct sand down into the turbo chamber while a reverse helix returns sand back to the turbo. The shaft and mixing blades are removable for fast cleaning.
Turbo Blending/Discharge
Sands are rapidly blended by a turbo consisting of a complex screw-type arrangement. A pneumatic gate controls discharge form the turbo chamber only when the sand is sufficiently blended to ensure excellent first sand quality.
The ability to instantly stop and start the sand flow into a mold.
- First sand discharged is good, with no waste at either end of mix cycle.
- Consistent binder levels are maintained for consistent mold quality.
- Reduced cleanout and maintenance time.
- Minimized wear.
Two or three part binder systems are pumped to spray nozzles in the mixing troughs via variable output recirculating pumps. DC motors drive the pumps with individual binder and catalyst output regulated by solid state motor control systems. An optional SPEEDLOCK rpm governor is also available. Controls are housed in a dust-tight enclosure.
