Urea spiral feeder

The working principle of the urea spiral feeder is to move powder and granular materials inside the tube by rotating the spiral blades.

The urea spiral feeder is usually used horizontally or slightly inclined, and can also transport materials vertically. It detects the weight of the material passing through the weighing bridge to determine the weight of the material on the tape. The digital speed sensor installed at the tail continuously measures the operating speed of the feeder. The pulse output of the speed sensor is proportional to the speed of the feeder. The speed signal and weight signal are sent to the feeder together, and the microprocessor in the control system processes them to generate and display the cumulative/instantaneous flow rate. The flow rate is compared with the set flow rate, and the control instrument outputs a signal to control the frequency converter to change the driving speed of the feeder, so that the material flow rate on the feeder changes, approaches and maintains the set feeding flow rate, thereby achieving the requirement of quantitative feeding.
