General-purpose Conveyor Belt
General-purpose belts are used to transport different kind of lump, bulk and unit-load cargos: from ferrous and nonferrous metal ores, competent rocks, coal, soft rocks, little abrasive and nonabrasive materials at temperature from - 45°С to + 65°С. An example of belts reference designation:...
General-purpose belts are used to transport different kind of lump, bulk and unit-load cargos: from ferrous and nonferrous metal ores, competent rocks, coal, soft rocks, little abrasive and nonabrasive materials at temperature from - 45°С to + 65°С.
An example of belts reference designation:
W1000-4 ЕР-200 6-2 specification belt type,
W1000 - belt width, mm;
quantity of side irons;
ЕР-200 - cloth sort;
6 thickness of carrying side cover, mm;
2 - thickness of back cover, mm;
M - rubber class;
mould EDGE- rubber capped edge.
Tractive carcass of type 2.1 and 2.2 belts consists of 3-6 EP-200 cloth covers (a thread of a polyester fiber is in basis, a weft is made of nylon). Between the cloth covers there are rubber covers to improve belt elasticity.
The carcass (or a belt hub) effects the transfer of driving force while exploiting conveyor belts that is why an application of EP cloth in our production as well as in the world practice secures the conveyor belts:
higher resistance (high breaking strength);
weak elongation in the time of working load so it excludes the necessity of multiple breaks of work for length regulation and an extra belt butt.
secure resistibility to impact loads;
high crosscut elasticity, that allows to make the grade edge of side rolls of a conveyor bigger.
Rubber linings and capped edges protect the belt's carcass from atmospheric, mechanical and other influence.
Depending on the conditions of exploitation and purpose of belts the rubber linings are made of A,M, N class rubber.
Mine conveyor belt
Mine rubber-fabric conveyor belts are oriented on conveyors of concentrators and surface complexes which transport the lump coal (up to 500mm) and lump rock (up to 300mm). A carcass of a belt consists of 3-6 fabric insert plies with fabric layers between them, with rubber carrying and back covers and rubber capped edges. The width of a belt is from 600 to 1200 mm inclusive. Polyester and polyamide clothes of the carcass are impregnated with a special mixture. Rubber linings are made of special ingredients - antipyrins. That effectively lows burning and gives a possibility to the belt not to continue burning after taking it from a source of flame.
Heatproof conveyor belt
Rubber-fabric conveyor belts type T1, T2, T3 are oriented on the transportation of hot material cargos with the temperature of 150°С, 180°С and 200°С at the enterprises of ferrous and nonferrous metallurgy, chemical industry etc.
