Operator Responsibility The operator’s responsibility does not end with efficient production. The operator usually has the most daily contact with the equipment and intimately knows its capabilities and limitations. Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or through a casual attitude toward machinery formed over a period of months or years. Your employer probably has established a set of safety rules in your workplace. Those rules, this ma

hoppers are not controlled nor read by the blender. Their existence is solely for the use of a low level alarm to be wired into a separate controller. These would not be present on a standard blender. The hoppers may be equipped with a polycarbonate sight glass. This is mounted in the upper cone section of the hopper. This is useful for a quick reference of the material level in each hopper. The supply/re-fill hoppers should be vented to the atmosphere through the louver located on th

Ingredient Metering/Transport Auger Assemblies Each metering auger assembly consists of a: • Cast aluminum motor mount • Cast aluminum feeder body • Aluminum feeder tube • Gearbox • Inverter-duty AC drive motor • Machined metering auger The metering auger assembly accurately meters the material from the ingredient weigh hopper at the calculated rate. The mass flow weigh hopper design allows more range of the load cell to be used for actually weighing the material and eliminates dynami

Lower Mass Flow Weigh Hopper Assembly The lower mass flow weigh hopper, otherwise known as the weighed common hopper, is used to determine the actual processing rate of the processing machine so that the blender can be slaved in to run at the learned rate. The hopper is constructed of spun aluminum and is of the mass flow type (See the glossary in the Appendix). It is supported by a load cell, and will carry a weight of material depending on how much is flowing into the hopper from the m

PLC Control Panel The PLC control panel may be mounted on the side of the blender frame, or remote mounted near the blender. It uses an Allen-Bradley SLC 5/04 programmable controller with standard 24 vdc input output cards. This design provides excellent blender performance along with easily replaceable off-the-shelf parts in case of any electronic component failure. Touch Screen Interface The PanelView 600 color touch screen display can be mounted up to 50 feet (15 m) from the PLC
