Abstract
A powder feeder system includes multiple electro-mechanical powder feeders structured for conveying powder compositions to a mixing hopper. A programmable logic control (PLC) can be incorporated into the multiple feeder system. The PLC can be programmed for determining a real-time powder flow rates for the powder feeders, receiving recipe data input related to creating a resultant coating composition, comparing powder composition flow rate data to the recipe data, and adjusting the operational aspects of motors and metering wheels associated with the multiple powder feeders in response to comparing the powder composition flow rate data to the recipe data. In various applications, the powder feeder system can be a subsystem of a thermal spray system configured for hardfacing and coating work pieces such as drill bits, road mills, shafts, mining tools, and/or stabilizers.
