Weigh System for Metallurgical Application


Weighing and Batching systems exist in virtually any industrial process.  In the metals industry, a metallurgical company that processes a trace mineral and produces high-quality metallurgical products, including spent catalysts, filter cakes and grindings, had a material weighing requirement. In this case, a material weigh batch system for metallurgical application has been provided consisting of six (6) transfer tote hoppers, as well as two (2) surge hoppers.  The transfer totes are 33.6 cubic-feet in size, with 24.9 cubic-feet of working capacity, and included fork pockets for movement of the transfer totes using a forklift truck.  The cone of each transfer tote is 65 degrees.

Note: Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are called alloys.

The surge hoppers are 8.5 cubic-feet, with a 5 cubic-foot working capacity, constructed of heavy-duty painted mild steel. Each incorporates a heavy-duty vibratory feeder and feeder controller with 4-20mA signal.  A platform scale is provided for each transfer tote that has a four (4) point load cell weighing system good for weights up to 10,000lbs. The weigh batching system feeds material onto a belt conveyor that is 40ft long and 12″ wide.

For the weigh batch system for metallurgical application Sterling Systems & Controls engineers provided a sequence of operations, sample PLC programming, and an equipment list for a control system to be developed by the customer.  While this is very unusual, Sterling Systems & Controls will work with customers to provide a custom system that performs and delivers what is needed and wanted by the customer.
