A directional discharge wing pulley having a plurality of wings that discharge material in a single direction while properly tracking the conveyor belt. The directional discharge wing pulley may include a plurality of directional discharge wings, which are generally angled in a single or primarily in single direction across the entire face of the pulley. When pulley is operated a reverse rotation direction, the conveyor belt continues to properly track and the material is discharged in the opposite direction. The wings may have bends to create flat sections, or formed in a multiple arc pattern to create smoother changes in geometry or increased wing angle near the ends of the pulley, while generally maintaining a single direction wing through the entire pulley. Strengthening rib bends may be added near the end of a straight wing to add rigidity reducing the likelihood of wing fold over. The wings may include secondary wings, for example, in a Herringbone pattern. In some applications, the wings may include longitudinal or circumferential wing tips. In other applications, the wings may include a multi-start spiral.

A dry bulk tank and a method of carrying a load and discharging a load therefrom. The dry bulk tank includes a tank assembly having a first wall that bounds and defines a first compartment for carrying a load therein and a second wall spaced outwardly from at least a portion of the first wall; wherein a second compartment is defined between the first wall and the second wall. The tank assembly includes an air piping system that is selectively actuated to place the first compartment and the second compartment under a substantially similar or substantially equal air pressure. In one example the air piping system pumps air into the first compartment and the second compartment. In another example the air piping system evacuates air from the first and second compartments.

A conveyor belt system includes a frame with a conveyor belt driven by at least two rollers so that an upper belt functions as transport surface and a lower belt functions as return, wherein the frame has an upper segment extending substantially above the upper belt and a lower segment extending substantially under the upper belt, wherein the upper segment has at least two upper standing walls with a mutual spacing which, at least at the position of the upper belt, is smaller than the width of the conveyor belt, and wherein the lower segment has at least two lower standing walls with a mutual spacing which is greater than the width of the conveyor belt, wherein the upper belt is supported on either side by a plate extending respectively from below the upper belt to an outer side of the lower standing wall.

A metal chip conveyor having an internal chip removal structure includes an endless conveyor belt. An accommodating room of a machine body is divided into an inner space and an outer space. Two sides of the conveyor belt are provided with chains each having chain links. Each chain link has a first opening facing the inner space and a second opening facing the outer space. Two support bushes are disposed at opposite sides of the casing. The conveyor belt passes around the support bushes and is supported by the support bushes. The support bushes cover the first openings of the chain links corresponding in position to the support bushes when the conveyor belt is running, thereby preventing the metal chips in the chain links from falling back into the inner space through the first openings and ensuring that the metal chips in the inner space to be discharged stably.

A tracked, portable radial stacker for stockpiling bulk material including a linear conveyor having a rear portion and a front portion and being designed to carry bulk material from a low position adjacent the rear portion to a higher position adjacent the front portion. A foot may be disposed adjacent the rear portion of the conveyor and designed to selectively contact the ground to facilitate pivoting of the conveyor. A continuous track system may include a frame to which the conveyor is mounted, the track system including a pair of driven, parallel tracks designed to contact the ground to convey the stacker from one position to another, and to be lifted off the ground when desired. A pair of mid-wheels may be mounted to the frame to be moveable between a raised position in which they do not contact the ground and a lowered position in which they contact the ground and lift the tracks off the ground. A rear wheel may be mounted adjacent the rear portion of the conveyor to be moveable between a raised position in which it does not contact the ground and a lowered position in which it contacts the ground and lifts the tracks off the ground to permit movement of the conveyor on the rear wheel.

A stockyard joint reclaiming system includes an outer output conveyor, a scraper reclaimer provided with a scraper mechanism, an inner feeder, and an inner output conveyor arranged below a stockpile. The scraper mechanism includes a chain and a scraper installed on a chain. The chain moves forwards or backwards under the action of a driving device to drive the scraper to push materials to a corresponding discharging port. The scraper mechanism drives the scraper through forward or reverse operation of the chain for pushing the materials to the output conveyor and a reclaiming line can be selected. A reclaiming mode is flexible and more output lines are available. When the material level is lower than a horizontal position, the scraper is driven to move through a reverse operation of the chain to push the materials to an upper part of the inner feeder for realizing reclaiming, thereby reducing unnecessary energy consumption and effectively guaranteeing the reclaiming capability of the scraper reclaimer.
