Conveyor , rocks, filling materials, etc.) and piece cargo. Widely used in quarries, mines, concentration plants, etc.
The main elements of the conveyor: traction, load-bearing or traction-carrying bodies- supporting and guiding elements- conveyor stav- drive. Constructive lines distinguish conveyors with a flexible traction body and without a traction body. At the first conveyors, the cargo moves together with the traction body on its working branch (belt conveyors, belt-rope conveyors, belt-chain conveyors, belt-conveyor conveyors, scraper conveyors, plate conveyors, elevators). At the second conveyors, the translational movement of the transported cargo is carried out with the oscillatory or rotational movement of the working elements (inertial conveyors – swinging and vibration conveyors, screw, roller). Conveyors are also classified according to the type of energy consumed – with electric, less often with hydraulic and pneumatic drives – according to the elevation angle – horizontal and slightly inclined (from 6 to -3 °), inclined (up to 18-20 ° and to -16 °), steeply inclined conveyors (over 18-20 ° or over -16 °) – according to the type of route – conveyors are straight, curved in the profile, curved (bending) in the plan – if possible, change the length of the conveyor belt – a constant length, a variable stepwise variable length with the separation of the traction and load-carrying organs (for example p, scraper conveyor), a variable steplessly variable length without disconnecting the traction-carrying body (for example, a telescopic belt conveyor) – according to the duration of the work in one place – stationary, semi-stationary and mobile, as intended – for underground, open work, general purpose, used on the surface of mines and processing plants, special (for example, feeders, reloaders, for loading machines, dump forwarders, transport and dump bridges, etc.).
