Gravimetric Blender
2.0 CONTROLS
When all components are available the dispense of a batch starts. The cycle begins with
closing the weigh-pan. Then each of the requested components is dispensed and weighed in
the weigh-pan. When all the components of the recipe are correctly weighed, the blend is
dischar ged into the mixing-chamber. A horizontal mixer mixes the compo nents to a
uniform blend which discharges to a storage bin, or direct ly into the machine hopper.
