continuous manufacturing mass flow microwave sensor powder feeder process analytical technology Continuous powder feeding is an important unit operation to introduce material consistently into a process. Continuous granulation, continuous mixing, continuous tablet compression etc., all rely on accurate and precise feeding processes. The most common type of powder feeder works by a loss-in-weight principle. In order to obtain the desired feed-rate, the feeder is placed on a balance which constantly measures the mass of fed powder and controls the speed of the feeder. In continuously running processes, powder feeders need to be refilled frequently. During this phase, the control balance ...
