conveyor belts used in the chemical and fertilizer industry have to carry a wide range of chemicals and other materials such as oil that can be very damaging to rubber. there are also other factors such as abrasive wear, the effects of ozone, high temperatures and important safety considerations such as the ability to resist fire.
severe applications, which have to absorb impacts: energy reduction better efficiency in critical operations: steelmaking and ports: blast furnace belt – where use of conventional belts is not recommended due to the high temperature long distance belts, which require high tensile strength: belt service life increase energy reduction: paper and cellulose
welded edge (w) – mesh only without reinforcing rods. at the belt edges the coil wires are looped together and welded. this type of edge finish allows for relatively smooth finish to the belt edge and is the most economic version of this belt style. knuckled edge (k) – mesh only without reinforcing rods.
the wear-resistant quality of the outer covers of a conveyor belt is the biggest single influence on the working life of the belt and consequently its ‘whole life’ economic cost. the rubber used for the outer covers usually constitutes at least 70% of
the conveyor belt transfers raw materials like coke, pellet and sinter to blast furnace area where they are used to produce liquid iron. this conveyor belt is driven by a gearbox that consists of a set of four gears placed in series. gearbox capacity was 850 kw, rated speed of 1500 rpm with service factor 2.13 and motor power 400 kw.

conveyor belting is not a “one size fits all” product: disregarding belt specifications in favor of price might help save pennies up front, but it will cost real dollars down the road. for example, it’s hard to dispute that using a mobile crusher that’s too small for the job will fail to meet yield requirements and will, therefore, reduce profits.

for example, ensuring disc screens have the proper diameter shafts and spacing to prevent films from wrapping, installing wider conveyor belts to distribute greater volumes of material and to allow for separation from the fiber stream and increasing sorting capacity and adjusting equipment to process it at scale are required to properly sort flexible packages from the rest of the incoming
conveyors, conveyor belts, trolleys and mobile raising platforms, which eliminate or reduce manual handling. ergonomics in the workplace the regulation is titled the manual handling of loads regulation. these regulations are likely to be remade in 2006 without substantive changes.
common conveyor belting materials include rubber, plastic, leather, fabric, and metal. transporting a heavier load means a thicker and stronger construction of conveyor belting material is required. belt conveyors are typically powered and can be operated at various speeds depending on the throughput required. the conveyors can be operated horizontally or can be inclined as well. belt conveyors can be troughed for bulk or large materials. roller conveyor
