Abstract: An impactor is externally securable to a container of flowable material to break up bridging or clumping of the material in the container. The impactor comprises a strike plate mountable to an outlet hopper or the like and a drive which axially reciprocally moves the hammer, such that operation of the drive causes the hammer to impact the strike plate to thereby pass vibrations into the container.

Abstract: A corner assembly for a tube conveyor system comprises a housing defining a wheel receiving area and a flow path with ports at opposite ends of the flow path. A wheel rotatably received in the wheel receiving area comprises a rim having an upper surface and a lower surface; a pair of spaced apart channels formed in at least one of the upper and lower surfaces of the rim; and at least one flapper pivotally mounted to the wheel inside of the rim. The flapper is freely movable between a position in which it is aligned with a wall of one of the channels and a position in which it is aligned with a wall of the other of the channels. Thus, when the wheel rotates, the flapper will sweep any material in the wheel receiving area towards and through one of the channels and into the flow path.

Abstract: A corner assembly for a tube conveyor system comprises a housing defining a wheel receiving area and a flow path defining an angle and having ports at opposite ends of said flow path. A wheel is rotatably received in the wheel receiving area. The wheel comprises a rim having an upper surface and a lower surface; at least one pair of spaced apart channels formed in at least one of the upper and lower surfaces of the rim; and at least one flapper pivotally mounted to said wheel inside of said rim. The flapper is freely movable between a first position in which the flapper is aligned with a wall of one of the channels and a second position in which the flapper is aligned with a wall of the other of the channels. Thus, when the wheel rotates, the flapper will sweep any material in the wheel receiving area towards and through one of the channels and into the flow path.

Abstract: An in-line feed supplement additive system comprises an additive hopper which can be disconnected from the feed line of a feed system and inverted to allow for cleaning of the additive hopper. The system includes a controller which, determines the proper speed of the motor which drives the conveyor of the additive hopper based upon the dosage of the additive and the flow rate of feed through the feed line. Further, the controller monitors the load on the additive hopper motor during delivery of additive to ensure a substantial constant rate of delivery of additive to said feed.
