A belt cleaner assembly is provided for cleaning a conveyor belt. The belt cleaner assembly includes an elongate support member for extending longitudinally across a conveyor belt. The belt cleaner assembly further includes a cartridge for supporting at least one scraper blade thereon. The cartridge is slidable over the support member. The belt cleaner assembly further includes slide blocks between the support member and the cartridge to space facing surfaces of the cartridge and the support member from each other.

A conveyor belt scraper blade includes a scraper layer supported by a support unit. The support unit has a base and at least two support fingers projecting side-by-side from the base. The fingers are arranged to flex to and from contact with a conveyor belt so as to optimise the lifetime of the scraper and minimise damage to the belt.

Conveyor belt cleaners are described. In some embodiments, the cleaner is installable and removable from the conveyor along a length thereof. In some embodiments, the cleaner is supported on one or more flexible supports. In some embodiments, the cleaner is removably attachable on the conveyor without modifying the conveyor. In some embodiments, the cleaner is removably mountable to one or more rails of the conveyor. In some embodiments, a side roller is supported on a drop bracket used to support a generally horizontal roller such as a return roller.

A return roller assembly that is designed for use as part of a conveyor assembly to improve the ability to clean the conveyor assembly. The return roller assembly includes a roller shaft that extends between side walls of a conveyor frame. A plurality of support rollers are positioned along the length of the roller shaft to support a lower run of a continuous conveyor belt. A spacer is positioned between each of the support rollers to define the position of the rollers along the roller shaft. The spacer can be snapped onto the roller shaft and includes a series of standoffs that space the inner surface of the spacer from the roller shaft. A series of cleaning fins extend radially from the outer surface of the spacer and impart rotation to the spacer relative to the roller shaft during cleaning with a spray of water. The spacer can be formed from an extrusion cut to length.

An exemplary crushing machine has a crusher for crushing media into crushed media, a reciprocating conveyor having a tray for receiving crushed media from the crusher, and a belt conveyor for receiving crushed media from the reciprocating conveyor and conveying the crushed media to a desired location. The reciprocating conveyor optionally includes a conveyor scraper that has a blade having a plurality of teeth extending to the tray, a blade support disposed proximate and transverse the tray of the conveyor, a hingeable connection attaching the blade to the blade support, at least one guide slideably supporting the blade support, and at least one actuator for actuating the scraper. Movement of the conveyor scraper across the tray prevents crushed media from sticking to the tray of the conveyor.

A continuous product-processing apparatus having a conveyor capable of repositioning product and cleaning itself of debris and a method for its operation. The apparatus includes a conveyor that transports products atop a conveyor belt along a carryway to a processing chamber. Upper and lower diverting rollers guide the belt along an S-shaped product-repositioning path segment of the carryway. The diverting rollers are rotated at a speed normally greater than the speed of the conveyor belt to cause the belt to slip on the roller's periphery, which effects a scraping action against the conveying side of the belt to dislodge debris from the belt and the rollers. One-way ratcheting drives or belt restricters positioned on the product-positioning path segment to limit belt excursion are used to prevent the belt from building up along the carryway and tightening in the lower return.

A sprocket adapted to be used in a drive unit of a chain conveyor for underground mining applications is disclosed. The sprocket may have a cylindrical body. The cylindrical body may have a front face, an axis of rotation (A-A), and a lateral surface. The sprocket may also have a scraping member provided on the front face. The scraping member may scrape off deposits during rotation of the sprocket.
