This invention refers to an enclosed conveyor (10) of bulk material (100) comprising an enclosure (20) and provided within said enclosure (20) with a conveyor belt (30) arranged over a set of rollers (40). More particularly, the invention relates to an enclosure (20) capable of improving the manufacturing process of the enclosed conveyor (10). The enclosed conveyor (10) comprises an enclosure (20) formed by a first side wall (21) and a second side wall (22) arranged over a bottom plate (23) and provided with a cover (24) disposed over said side walls (21, 22). The enclosed conveyor (10) comprises at least one set of rollers (40) comprising a first inclined roller (41) mounted on the first side wall (21) and a second inclined roller (42) mounted on the second side wall (22), and a conveyor belt (30) arranged over the set of rollers (40). According to the invention, each side wall (21, 22) comprises a respective vertical section (211, 221) arranged over the bottom plate (23) and a respective support section (212, 222) inclined inwardly of the enclosure (20), each support section (212, 222) being inclined along an entire longitudinal extension of the respective side wall (21, 22), the first inclined roller (41) being mounted on at least part of the support section (212) of the first side wall (21) and the second inclined roller (42) being mounted in at least part of the support section (222) of the second side wall (22). Thus, with the support sections (212, 222) inclined across all the longitudinal extension of the side walls (21, 22), the manufacturing process of the enclosed conveyor (10) becomes easier and cheaper when compared to the manufacture of a conventional enclosed conveyor.

A trough conveyor that transports fine bulk material and is exposed to windy conditions may include a belt for transporting bulk material, a center roll for supporting the belt, first and second wing rolls that support angled segments of the belt, a frame that supports the center roll and the first and second wing rolls, and a hood cover disposed above the belt. The trough conveyor may also include first and second baffles that form labyrinths that help attenuate wind velocity over the fine bulk material. The baffles may also help contain fine bulk material that is stirred up within a stilling space formed between the hood cover, the belt, and the baffles. In addition or in the alternative, the trough conveyor may include fairings that deflect crosswind beneath the belt.

An enclosed belt conveyor system has a rail track (1) and spaced apart carriages (35) that run on wheels (40) supported by the trail track. A continuous carry belt (10) is supported by the carriages (35) and has an enclosed configuration where the carry belt (10) encloses a bulk material for transport by the system. One or more belt guides (45) are positioned along the rail track (1) and engage the continuous carry belt to maintain it in its enclosed configuration.

A thermal processing apparatus (20) includes a spiral conveyor system (22) configured into an ascending spiral stack (26). An air balance tunnel (40) includes a tunnel housing (76) positioned inside of a thermal processing chamber adjacent an outlet opening (36). A conveyor belt (24) travels through the housing on its way out of the processing chamber. An air pervious ejector assembly (78) is positioned within the housing at an elevation above the conveyor belt (24). An air pervious evacuation sheet (80) is located within the housing at a location beneath the conveyor belt (24). An air pervious cover assembly (150) is positioned over the conveyor belt (24) at a location just before the conveyor belt enters the air balance tunnel (40). The cover sheet (150) is connectable to the ejector assembly (78) so as to remove the ejector assembly from the tunnel housing (76) by manually moving the cover assembly (150).

A device for separating a conveying member from a support structure includes an elongated member for engaging a portion of the conveying member, and a lever. The elongated member includes a first end and a second end. The lever is coupled to at least one end of the elongated member, and the lever includes a base end and a distal end. The lever is pivotable between a first position in which the elongated member is lowered and a second position in which the elongated member is elevated.

A conveyor system (1) for the continuous or discontinuous conveyance of a reactive and/or hot and/or abrasive material to be conveyed along a conveyor path includes a system housing (3) enclosing the conveyor path, which has at least one fluid inlet (5) for the introduction of fluid into the system housing (3), at least one fluid outlet (7, 9) for the discharge of fluid out of the system housing (3), a charging inlet (4) for introducing material to be conveyed into the system housing (3), and, apart from the at least one fluid inlet (5), the at least one fluid outlet (7, 9) and the charging inlet (4), are implemented in a technically fluid-tight manner.
