More Information
Summary:An apparatus and method for combining multiple materials into a stream. The multiple materials may include both a major material and one or more minor materials. The minor materials are added using inlet tubes. The major and minor materials are added at transient or steady state flow rates, depending upon a command from a control signal. The apparatus and method utilize a control system which does not have flow control valves, flow control feedback loops or a dynamic mix tank. The actual flow rates track the commanded flow rates, but deviate by an error. The claimed arrangement provides a time-based error believed to be unobtainable in the prior art.
