20150175280 | BULK BAG DENSIFYING APPARATUS AND METHOD - An apparatus for densifying particulate contents of a bulk bag, that includes a support element and a pressure-applying element for supporting between them a bulk bag containing particulate contents with a pressure to the bag supplied by the pressure-applying element, and a vibrator carried by one or the other of the support element and the pressure-applying element for transmitting vibratory energy through the contents of the bag back and forth between the support element and the pressure applying element for densifying the contents of the bag and leveling a top surface of contents of the bag at a top end of the bag. A related method is also disclosed. | 06-25-2015 |
20150041285 | TENSIONING ASSEMBLY FOR CABLE DRAG CONVEYOR WITH TENSIONING ASSEMBLY AND METHOD OF CONTROLLING TENSION IN A CABLE DRAG CONVEYOR - A tensioning assembly for a cable drag conveyor. The conveyor includes a head pulley mounted on a head pulley shaft positioned in a head pulley housing and a tail pulley mounted on a tail pulley shaft positioned in a tail pulley housing, infeed and discharge conveyor tubes interconnecting the head pulley housing and the tail pulley housing, and an endless rope having conveying disks attached to the rope positioned in the infeed and discharge conveyor tubes and around the head pulley and tail pulley. The tail pulley housing is positioned in a stationary position in relation to the head pulley and the head pulley housing. The tail pulley shaft and tail pulley is positioned on the tail pulley housing for movement in relation to the tail pulley housing, the head pulley and the head pulley housing. A tensioner moves the tail pulley to maintain the tail pulley at a distance in relation to the head pulley that results in correct tension on the rope during its travel through the cable drag conveyor. | 02-12-2015 |
20140311872 | CABLE CHAIN WITH MOLDED FLIGHTS FOR TUBULAR DRAG CONVEYOR - A chain link for a tubular conveyor, including an elongate endless loop having first and second opposed, spaced-apart link segments that each include a respective opposing, inwardly extending anchoring recess on an outer surface adapted to receive and retain a conveyor chain flight on the chain link. | 10-23-2014 |
20080289935 | DYNAMIC TENSION CONTROL APPARATUS AND METHOD FOR AERO-MECHANICAL CONVEYOR - A tensioning assembly for use in an aero-mechanical conveyor for moving bulk materials. The conveyor includes upper and lower housings having head and tail pulley assemblies mounted therein. The tensioning assembly includes first and second extendable tubes that define sections of inflow and outflow conveyor tubes that interconnect the upper and lower housings. An endless rope assembly is disposed within the conveyor tubes and around the head and tail pulleys. An adjustable actuator is positioned in cooperative engagement with the first and second extendable tubes. When the actuator is in a first position, the extendable tubes have a first length and when the actuator is in a second position, the extendable tubes have a second length. The actuator is configured to move between the first position and the second position in response to changes in tension within the endless rope assembly as indicated by a signal from a tension measuring device. | 11-27-2008 |
