Abstract:
A wall (2), for receiving one or more wear plates (1), has openings for receiving at least some of the fastening elements (11, 12) of the wear plates (1). The wall has, furthermore, gaps (22), with dimensions corresponding to the width and thickness of the wear plates (1). Slots (23) extend from the gaps (22). The slots (23) correspond to the fastening elements (11, 12) of the wear plate (1). The fastening elements (11, 12) of the wear plates (1) can pass through the wall (2), through the slots (23).
Abstract:
A system and method for material handling includes a first portable conveyor for feeding material to a mobile bridge conveyor for the material to be stacked via a stacker until a discharge end of the mobile bridge conveyor is at or within a predetermined distance of a discharge end of the first portable conveyor. The first portable conveyor moves away from the mobile bridge conveyor after the discharge end of mobile bridge conveyor is at or within the predetermined distance of the discharge end of the first portable conveyor. A second portable conveyor that feeds material to the first portable conveyor rotates such that a discharge end of the second portable conveyor is moved towards the mobile bridge conveyor until reaching a feeding position for feeding material to the mobile bridge.
Abstract:
The aggregate processing system is a substantially closed onshore system that provides significant improvement in economy by substantially eliminating the spread of dust and dirt and/or the partial filling of the berth with sediment during the offloading of aggregate materials from a bulk cargo ship. The system includes one or more extractors that draw the bulk aggregate material from the hold(s) of the ship by entraining the aggregate in a stream of water and air. The aggregate is automatically cleaned during this step, and passes to a separating hopper where the sand and water settle out and the clean gravel is transferred to surface transport. The sand and water pass to a settling tank, where the sand is recovered for use and the water is recycled for continued use.
Abstract:
A conveyor chain includes a plurality of chain links connected together in a chain, each including a pair of forward arms having a space therebetween and a rearward arm extending in a rearward direction. The forward arms of one link are configured to receive the rearward arm of an adjacent link to form a continuous chain. The rearward arm of each link extends a distance from the forward arms so that when adjacent links are coupled together, an engagement space is created between the forward arms of the links. The engagement space is configured to receive portions of sprockets that would engage the forward arms of the link for driving the chain.
Abstract:
A belt conveyor and a crushing unit includes a conveying upper run presenting a feed end and a discharge end, and a return lower run, with the conveying upper end including a curved extension, which is concave and ascending and presents an inlet lower portion and an outlet upper portion of the conveying upper run, where the belt conveyor imparts to the material a path that is substantially coplanar and opposite in relation to that imparted to the material in the inlet portion, and with ascending curved path presenting at a determined belt speed, a centrifugal force sufficient to maintain the material seated against the curved extension of the conveying upper run until reaching the discharge end.
Abstract:
Roller-guided conveyors are described herein. An example roller-guided conveyor comprises a first holder and a second holder and a first guide roller and a second guide roller. The first guide roller has a first axis of rotation and pivotally coupled to the first holder about a pivot axis that is eccentric relative to the first axis of rotation. The first guide roller is spaced a distance from the second guide roller to guide a conveyor belt therebetween.
Abstract:
A loading assembly is provided that is configured to load transport containers with bulk material quickly and efficiently. A container support assembly is also provided that facilitate alignment and stable support of the container throughout loading. In use, a load bin of the loading assembly is inserted and retracted relative to the container by a drive mechanism. The barrier assembly confines the contents of the load bin in the container while the bin is retracted, allowing the contents of the bin to remain within the container upon removal of the bin. The container support assembly includes left and right ramps disposed along side the container. The ramps each include a support surface having an increasing height differential with reference to the ground from the distal end to the proximal end. The support assembly further includes an interface assembly configured to attach to the container and to engage the support surfaces of the left and the right ramps to distribute load onto the ramps. Thus, with the container properly positioned, a substantial portion of the container's load is borne by the ramps.
Abstract:
A method for manufacturing a self-closing tubular belt with predetermined compression forces at a longitudinal joint comprises winding a plastic material onto a small mandrel such that the plastic material thickness is not more than the height of a mandrel spiral rib, curing the plastic material, and removing the plastic material from the small mandrel, resulting in the plastic material being in a form of a spiral rubber spring having gaps between its twists. The resultant rubber spring is then wound on a larger mandrel thereby forming winding gaps. These winding gaps are then filled with a raw filler material, and these are processed so that all turns of the rubber spring are joined together monolithically. This is removed from the mandrel by making a longitudinal split in the spring, producing the tubular belt having prestressed regions formed by the spring, and resisting portions formed by the filler material.
Abstract:
The invention includes a method and an apparatus for treating, in particular cooling, a layer of bulk material by means of a stream of gas passed through it on a grate. The grate includes a plurality of elongated planks which extend in a conveying direction and are driven in advancing and return strokes in the conveying direction in such a manner that at least two adjacent planks are moved forwardly simultaneously and are moved backwardly non-simultaneously. Since the material located on a plank which is being moved back is prevented from completely following the plank moving back by the friction generated with the material located above the adjacent planks or with the wall, the conveying effect in the conveying direction outweighs the conveying effect in the opposite direction.
Abstract:
A gapless side guard for use with a modular belt having modules connected to one another by pivot rods. The gapless side guard has a continuous strip of flexible material for retaining materials being transported on the modular belt. In one embodiment, the strip has strip openings and the strip is connected to the module with brackets. The brackets have anchors and the strip openings are positioned around the anchors such that the strip is thereafter joined to the anchors. The bracket has a stud side with studs extending from the stud side. The module has stud openings and the studs are snapped into the stud openings in the module and are thereafter joined to the module. The strip is flexible such that when the modular belt is driven over a sprocket it is capable of elongating as the distance between the brackets increases.
