PROCESS AND APPARATUS FOR THE CONTROL AND REGULATION OF THE PRESSING PROCESS OF A BRICK PRESS

摘要

A brick press for the production of formed bodies from free- fa.owing materials has a measuring and comparison device, in which pressing force and press path are detected from the beginning of the pressing process and are compared with a preset pressure curve, which represents the pressure/path setpoint value of the pressing process. Any deviations from the force/path setpoint value determined outside a range of tolerance of pressure curve are used as a signal for early ending of the pressing process. Reject formed bodies resulting in this case can be crushed effortlessly and again recycled in the initial material to be pressed without subsequent treatment. A process is also disclosed for the control and regulation of the pressing process.
