Abstract:
A belting (10) reinforced with at least one fabric ply (16). The fabric ply (16) is a composite fabric (26). The fabric (26) has two woven layers (28, 30) and an intermediate third layer of straight warp yarns (34). The woven layers (28, 30) and straight warp yarns (34) are bound together by a plurality of binder yarns (38). Each layer (28, 30, 34) of the fabric (26) contributes substantially 25-40% to the overall strength of the fabric (26). The composite fabric (26) may be used in a multi-ply belting (10) for heavy duty applications; wherein the fabric ply (26) is the center ply (16) and provides approximately 50 to 75% of the overall belting strength. The fabric (26) may also be used as a single reinforcing ply for light duty application belting.
Abstract:
A belt conveyor for conveying granular material comprises a tube and a hopper. Guide members guide the belt from a flat orientation as the belt leaves the lower roller into a cupped orientation as the belt enters the hopper. The cupped orientation is maintained by sliding contact at an interface between the lower surface of the belt and the hopper walls as the belt passes through the hopper. Left and right baffle members are attached along the hopper side walls and thereby prevent the granular material from sliding down the hopper walls into contact with the interface between the lower surface of the belt and the hopper walls. The belt has a width that is substantially fully exposed to granular material entering the hopper. A method of increasing the capacity of a belt conveyor comprises reducing the width of the flashing covering belt side portions.
Abstract:
A receiving section is located in the region of a conveyor belt at which loads are deposited onto the belt to support the belt in use. It is a problem with known receiving sections that they have difficulty in dealing with larger loads which tend to be carried by broader conveyor belts. A resilient mount adjacent a centre line of a conveyor is disclosed which has improved spring characteristics which enables an associated receiving section to deal with larger loads.
Abstract:
A catenary conveyor belt support apparatus for supporting a conveyor belt having a first edge and second edge. The support apparatus includes a first support block having a top surface for supporting the conveyor belt at the first edge and a second support block having atop surface for supporting the conveyor belt at the second edge. First and second idler strings extend between and are connected to the first and second support blocks. Each idler string includes one or more idler rollers for supporting the conveyor belt. A pair of resilient biasing members are respectively attached at a first end to each idler string and at a second end to an anchor member. The support blocks and the resilient biasing members inhibit misalignment of the idler rollers and movement of the first and second edges of the conveyor belt to reduce the escape of conveyed material from the conveyor belt.
Abstract:
A metallic conveyor belt arrangement for transporting bulk material comprises a metallic conveyor belt closed in itself and extending along a longitudinal axis. The metallic conveyor belt forms at least two ends, such as a slack end and a tight end, and at least a first and a second deflector loop connecting said ends. The metallic conveyor belt has first and second surfaces, each on one side thereof, of which one surface serves for loading the bulk material to be conveyed on it. A tensioning device for said metallic conveyor belt is arranged in the range of a second loop. At least one V-belt is secured to the engagement surface of the metallic belt. A roller-shaped drive wheel subdivided into at least two adjacent parts is secured to the drive shaft. The parts form a circumferential groove between them for receiving the V-belt. An axial tightening device is on the drive shaft for tightening the parts together in the direction of the shaft axis. Alternatively or in addition, at least one tilting arrangement for enabling tilting movement of at least one of the deflector wheel or the drive shaft about a tilting axis may be provided.
Abstract:
A bucket conveyor for conveying loose grain in different directions, comprising a bucket having: an opening leading to the interior of the bucket; and a dead space constituting part of the interior at the rear, the space not filled with loose grain when grain is loaded from above to or beyond the level of the opening, its volume being larger than the filled volume immediately below the opening. The conveyor does not spill the loose grain even when the angle of the bucket is changed.
Abstract:
A conveyor for conveying bulk material includes a conveyor loop (2) having an upper section forming a transport deck (5) extending along a transport path and a lower return section. The conveyor loop (2) includes an array of pins (7) and connections (8, 9) interconnecting the pins (7) and an array of carrier beams (10) each extending transverse to the array of pins (7) and connections (8, 9). A side barrier (11) above and along a side of the transport deck (5) for restraining bulk material from moving laterally off the is formed by an array of side barrier plates (24; 124). The side barrier plates (24; 124) are each fixedly connected relative to axes (35) of a pair of the pins (7). Leading and trailing ends (36) of successive side barrier plates (24; 124) are in at least close proximity of each other.
Abstract:
A conveyor assembly which includes a continuous belt for carrying bulk material such as stone, ore, grain etc. is provided. The conveyor transports the material to a discharge point where the material is discharged from the belt as the belt wraps around a head pulley. The belt is troughed between the area that the material is loaded onto the belt and the head pulley. A plurality of belt supports support the belt between the area where the material is loaded onto the belt and the head pulley. Each belt support includes a central roller for providing generally frictionless rolling support for the central portion of the belt. Each belt support further includes a pair of wing supports for supporting the troughing side of the belt. Each wing support includes a roller adjacent the central roller and a pair of slider bars supporting the marginal edges of the belt. The slider bars support the marginal edges of the belt between successive belt supports to retain the belt in engagement with a skirt to prevent spillage of material.
Abstract:
A device for controlling the conveyance of particulate material on a conveyor belt comprises a frame with an endless belt attached thereto. The apparatus is positioned above the conveyor belt and in frictional contact therewith whereby the motion of the conveyor results in motion of the endless belt on the apparatus. The particulate material thereby is passes between the endless belt and the conveyor belt and any bouncing movement of such material is prevented. Use of the present invention on conventional conveyor belts controls the dispersion of the particulate material carried thereon and allows for the speed of the conveyor to be increased. The present invention is suitable for use with a conveyor apparatus used with a truck and commonly known as a “stone slinger”.
Abstract:
A conveyor apparatus and method for a continuous haulage system and continuous conveyor belt are disclosed for carrying coal or ore. A middle roller and side sliders are connected with substantially flexible linkages on a roller-slider support piece supporting the continuous conveyor belt. Three apertures are positioned on the holding frame to adjust and control the tracking angle at which the support piece receives the continuous conveyor belt. In one aspect, the holding frame is provided by a plurality of floor-supported frame members held in position by belt tension, the holding frame being capable of rapid and efficient extendable, retractable construction in the mine, and wherein substantially flexible connecting linkages are positioned to connect the middle roller and the side slider and to connect the side slider to a holding frame for holding the roller-slider support piece. Rails connecting and hold adjacent frame members in position by press-fit attachment of the rails to the frame members. The rails preferably are quickly rotatable to change the top wearing surface.
