conveyor transport is the broad category of transport modes that includes modes developed from the idea of a conveyor belt. examples include: conveyor belt, two or more pulleys, with a continuous loop of material that rotates about them; escalator, a moving staircase, for carrying people between floors of a building
they pick up their load from a boot, a pit, or a pile of material at the foot pulley. the buckets can be also triangular in cross section and set close together on the belt with little or no clearance between them. this is a continuous bucket elevator. its main use is to carry difficult materials clarification needed at slow speed.
a ropeway conveyor or material ropeway is essentially a subtype of gondola lift, from which containers for goods rather than passenger cars are suspended.. ropeway conveyors are typically found around large mining concerns, and can be of considerable length. the comilog cableway, which ran from moanda in gabon to mbinda in the republic of the congo, was over 75 kilometers 47 mi in length.
the fixed pulley on the upper shaft is driven at constant speed by a belt from the power source. the loose pulley 'idler' allows the machine to be stopped in isolation – necessary for changing speed. the stepped pulleys left provide three drive speeds for the machine tool not shown , depending on which pair of pulleys is connected by the .
they can be made of many materials. wood staves, concrete staves, cast concrete, and steel panels have all been used, and have varying cost, durability, and airtightness tradeoffs. silos storing grain, cement and woodchips are typically unloaded with air slides or augers. silos can be unloaded into rail cars, trucks or conveyors.
bulk material handling is an engineering field that is centered on the design of equipment used for the handling of dry materials. bulk materials are those dry materials which are powdery, granular or lumpy in nature, and are stored in heaps.
a sheave / ʃ iː v / or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley.the sheave spins on an axle or bearing inside the frame of the pulley. this allows the wire or rope to move freely, minimizing friction and wear on the cable.
