System Component Description
This section describes the various components of the blending system.
Supply Hoppers
The material supply hoppers are located on top of the blender frame. These hoppers store a
supply of material for the individual metering devices. They are sized based on the total
throughput of the blender.
The blending system does not include any level indication devices on the unit. Optional low-
level sensors are available. The blender controller will alarm if it runs out of material while
trying to make a batch, but low-level sensors will alert floor personnel to the problem sooner.
Many hoppers are equipped with a sight glass and/or access door.
