5-1 OS/OA Blender Sequence of Operation
1. Blender is started by turning system on or material dropping below level
switch in mix chamber.
2. Metering gates are opened (or auger motors are turned on) to meter material
into the weigh hopper in the programmed order.
3. Each component is weighed then the batch is dumped into the mix chamber
(provided the mixer “High level” switch is not covered).
4. The material is mixed in the mix chamber and flows into the processing
machine.
5. The optional slide gate below the mixer may control the flow of material to
the molding machine or extruder.
