Abstract: A bindery compactor and/or baler receives and compacts or bales simultaneously large particulate paper waste and pneumatically conveyed fine paper waste. The compactor and/or baler operate with a platen cycling within a chute. The platen is normally forward in the compacting position with a sealing plate attached to the platen extending to close the top of the chute and form the bottom of two waste paper receiving bins. A first of these paper waste-receiving bins is for large particulate paper waste loaded from a cart dumper or conveyor. A second of these waste-receiving bins is for pneumatically transported fine paper waste from a cyclone separator. In both bins, accumulation of paper waste occurs to a height where an electric eye triggers cycling of the compactor only when a sufficient volume of material is present for compaction and an excess volume is present for preventing pneumatically induced escape of material.

The pressing method makes it possible to press a ceramic stacked layer structure efficiently using the small and light die body.

Abstract: A bindery compactor receives and compacts simultaneously large particulate paper waste and pneumatically conveyed fine paper waste. The compactor operates with a platen cycling within a compactor chute, in which the platen is normally forward in the compacting position with a sealing plate attached to the platen extending to close the top of the chute and form the bottom of two waste paper receiving bins. A first of these paper waste-receiving bins is for large particulate paper waste loaded from a cart dumper. A second bin of these paper waste-receiving bins is for pneumatically transported fine paper waste from a cyclone separator. In the second bin, accumulation of fine particle paper waste occurs to a height where an electric eye triggers cycling of the compactor. When cycling is triggered, the compactor platen retracts from extension to the chute withdrawing the sealing plate and allowing the stored paper waste from either bin to fall into the chute ahead of the retracting platen.

When the pressure applied to pressure rod 7 by actuator 6 exceeds the free weight of sliding frame part 2, a reactive force generated from pressure rod 7 operates to raise sliding frame part 2, thus simultaneously applying a uniform load to opposing sides of the workpiece located between pressure rod 7 and the lower punch 9 operatively connected to the sliding frame part 2.

Abstract: A system and method for determining the fullness of a large capacity waste container (20). Each time the a compactor (22) is used to compress the waste in the container a monitoring unit (24) determines the highest hydraulic pressure generated by the compactor during a selected period of compactor use. The monitoring unit also maintains a count of how often the compactor is used. After the container is filled and emptied a number of times, the monitoring unit then divides the highest hydraulic pressures for the uses by the number of uses to obtain a pressure/use value. This pressure/use value is used as a variable to determine a maximum uses value representative of the number of times the compactor can be used before a container is filled. Once a container data representative of how full a container is, and how many compactor uses remain, is calculated by comparing the number of times the container has been used since it was emptied to the maximum uses value.
