Abstract: A conveyor belt assembly may include a conveyor belt having an elastomeric layer, a chain adjacent a side edge of the conveyor belt and a flexible bridge extending between and connected to the chain and the conveyor belt along the side edge. The chain, bridge and conveyor belt may be driven to revolve by a sprocket engaging the chain.

Abstract: A machine for quenching, crushing and feeding material that includes a continuous loop drag chain conveyor. A first portion of the conveyor travels through a quenching tank and a second portion travels beneath the tank's bottom wall. Large blocks of hot material are dropped onto the conveyor inside the tank. A rotary crusher is positioned to crush the cooled blocks into sized pieces as they exit the tank. The sized pieces drop through an opening in the conveyor's frame and onto the second portion of the conveyor. The pieces dewater on the second portion of the conveyor and drop through a discharge opening and into a removal device for transfer to a remote location for further processing.

Abstract: A material breaker for breaking larger lumps of material into smaller pieces. The breaker includes at least a first, second and third processing region arranged in series. Each of the processing regions includes an inclined scalping grizzly, a rotor and an impact grid. Large lumps of material move down the scalping grizzly, are engaged by the rotor and accelerated toward the impact grid where they are fractured. The scalping grizzlies and impact grids have openings therein through which pieces of a predetermined desired size and smaller may pass without further engagement in the breaking process. The rotor speeds are sufficiently low enough to enable the larger lumps of desirable material to break into the predetermined size without producing excessive particulates or generating large quantities of dust.

Abstract: This invention relates to an endless fold-over type of conveyor belt for use in conveying relatively-loose bulk material in an enclosed manner to prevent spillage, dusting and contamination of the material and allows the belt to operate at steep angles. The belt comprises essentially a rectangular uniform cross-sectional shape having a substantially greater width than thickness. Two similar arrays of longitudinal grooves are located on the side of the belt opposite to that carrying the load, the grooves being spaced on both sides of the belt medial portion to provide a pair of hinged areas for folding and unfolding the belt. The longitudinal grooves preferably are V-shaped or U-shaped and between one and five grooves may be provided in each array at about one-quarter the belt width from its edges to provide a pair of overlapping edge flaps to cover the medial area when in folded relation.

Abstract: A flexible endless conveyor belt with fold-over capacity contains support cables longitudinally oriented and internally disposed to the belt. The support cables are distributed throughout the medial portion and the flaps of the belt. In one embodiment of the invention, the hinged areas intermediate the flaps and the medial portion further contain fold cables of a significantly smaller cross-section than those contained in the medial portion and the flaps. In a second embodiment of the invention the hinged areas do not contain fold cables. The first and second embodiments can additionally include transverse cables oriented transversely to the support cables, thus providing third and fourth embodiments of the present invention. The four embodiments can additionally contain grooves in the hinged areas or can contain no grooves, thus providing four additional embodiments.

Abstract: An apparatus for feeding a particulate material. There is a drum having a peripheral surface and a central axis which is rotatable about its central axis. There is a first particulate material retaining wall which has an inner and outer edge. This wall is positioned such that said outer edge is remote from the peripheral surface of the drum and the inner edge is adjacent the peripheral surface of the drum. The inner edge is moveable from said peripheral surface of said drum. A second particulate material retaining wall having an inner and outer end and positioned such that said outer end is remote from the peripheral surface of the drum and the outer end is remote from the peripheral surface with the drum. The first particulate retaining wall is preferably spaced from the peripheral surface of the drum by a distance which corresponds to the angle of repose of the particulate material being used.

Abstract: A conveyor cleaning and residue control system for use with a conveyor includes an air knife and a deflector. The air knife impinges an air stream against the conveyor to blast residue from the conveyor, and the deflector redirects the air stream and the residue loosened by the air stream toward a chute. The flow of the air stream toward the chute causes at least a portion of the air-borne residue in the vicinity of the conveyor to flow toward the chute with the air stream such that the residue becomes supersaturated and forms macro-particles that precipitate out of air suspension. The air knife and deflector thus recycle the residue carried by the conveyor instead of requiring it to be evacuated. In the first embodiment, the deflector includes a pair of non-coplanar blades that are attached to one another. The deflector is both rotationally and translationally adjustable with respect to the conveyor. A second embodiment is disclosed wherein the deflector is curved.
