A diverter valve is provided for use in directing a flow of bulk material from a source to at least one receiver. Included in the present diverter valve is an inlet housing having an inlet port and partially defining a valve chamber, an outlet housing connected to the inlet housing, having at least one outlet port and defining an end of the valve chamber. A rotating disc is rotatably disposed in the chamber and constructed and arranged for selectively creating fluid communication between the inlet port and diverting the flow to a selected one of the at least one outlet port.

The unloading device comprises: at least two conveyor belts each extending in a longitudinal direction (X-X′) between an end for receiving the bulk material and an end for discharging the bulk material, the receiving end being level with the vehicle; and a hopper comprising an inlet orifice and at least one outlet orifice of the bulk material, the at least one outlet of the hopper being configured to discharge the bulk material onto the receiving ends of the belt conveyors.

Disclosed herein is a conveyor system including a conveying element with one or more bottoms and upright side walls, where the bottoms and the upright side walls together form a trough in which bulk products may be transported along a main flow, where the conveying element includes one or more openings through which bulk products may be poured, where the conveyor system includes a gate for closing a particular opening, where this gate may be moved between at least a closed position and an open position, where the one or more openings extend on the side walls, and where the gate may be moved slidably along the specified opening.

A portable multi-sectioned boom concrete conveyor assembly that includes a feeder conveyor configured to transport a construction material toward a distal end of the feeder conveyor and a main conveyor boom assembly including a plurality of main conveyor boom sections. The plurality of main conveyor boom sections may include a proximal main conveyor boom section and a distal main conveyor boom section that is rotatably coupled to one of the plurality of main conveyor boom sections about a revolution joint, has a second main conveyor belt spanning from a first end of the distal main conveyor boom section to a second end of the distal main conveyor boom section, and is operably configured to independently revolve approximately 360° about the revolution joint. The first and second main conveyor belts are operably configured to transport the construction material toward the second end of the distal main conveyor boom section.

A piler conveyor system for screening debris such as tare dirt from materials such as beets as the materials are conveyed across a piler. The piler conveyor system generally includes a frame supporting an upper conveyor and a pair of lower conveyors. The upper conveyor is adapted to receive materials such as beets. As the materials are conveyed by the upper conveyor, debris such as tare dirt or the like will fall through screening openings in the upper conveyor and onto the lower conveyor. The lower conveyor may then dispense the debris through a debris opening. The materials will drop off the end of the upper conveyor and fall onto the second lower conveyor, which will convey the screened materials to be dispensed.

A weighing apparatus for the preparation of a mixture of granular components that comprise batches of material required by a plurality of processing machines in a plant for the manufacture of plastic products is described. The apparatus comprises a Multi-Channel Gravimetric Batch Blender (MCGBB) configured to weigh predetermined weights of the raw materials and to combine the weighed portions of raw materials into batches according to a predetermined recipe for each processing machine and a computer that controls the operation of all components of the MCGBB. The MCGBB comprises several weighing units arranged in a way that allows material weighed in each of the weighing units to fall through individual chutes via a common funnel into a manifold that distributes the weighed batches to several processing machines via a system of delivery pipes.

A dual positioned recirculating chute that would allow the operator to run the plant in either closed circuit or open circuit position. While in closed circuit position, the plant will run rock through and the chute will provide as a recirculating chute for oversized rock to travel from the recirculating conveyor back into the feeder hopper for re-crushing. The operator can then reposition the chute to the open circuit position, which will change the direction of the chute away from the feeder hopper and discharge material off the side of the plant. This can be oversized rock material to form an additional stock pile or be redirected to an off-plant conveyor. This can also allow for the removal of trash and unwanted material from the plant cycle without the need for a full plant shutdown, locking out the proper equipment, and manually removing before restarting the crushing process again.

Method and apparatus for the reduction of environmental pollution produced in material handling operations, especially but not exclusive in the transfer of material between two conveyor belts, one of material input and one of output of said material, are disclosed here. The pollution reduction mechanism is based on the reduction of the distance in free fall that the material travels from the material input conveyor belt, by means of maintaining live load of material inside the chute. To achieve this objective, the method considers: measuring the weight of the chute with material; the measurement of one of the two flows; the calculation of the rapidity of change of the weight of the chute; and the regulation of the mass flow of input to the chute or the regulation of the mass flow of output from the chute.
