ABSTRACT:
A briquette press apparatus for compacting powdered materials having a programmable control monitoring the forces of the press. During compression, the programmable control measures the compression force being asserted against the powdered material and regulates the press so that the compression force equals a programmed reference value. During decompression, the programmable control monitors the pressure release rate of the press and regulates the press so that the measured pressure release rate matches a programmed reference rate.
