Use of steel cord conveyor belt problems

Design and manufacture and use of steel cord conveyor belt for nearly 50 years. Use in mine production in good condition, the overall economic efficiency was significantly

superior to other modes of transport. But in material handling conveyor the long-term production practice, some industrial and mining enterprises found that the domestic steel cord belt conveyor surviving

in

Some questions:
1 , roller poor performance , life is short
( A ) short service life . Idlers manufactured abroad , the minimum life made ​​clear stipulations . Generally not less than 20000h. pallet conveyor Domestically manufactured roller, the minimum

life have not been clearly defined. Typically 5000-6000h. Worst of 200h or so. Steel Cord Belt Conveyor

Long distance conveyor idlers lot number , and sometimes up to tens of thousands . Because life is short roller , consumed in large quantities , not only a waste of a large

number of steel and bearings , but also to the use and maintenance of a lot of trouble , but a problem occurs , it will seriously affect production.
( 2 ) , running drag coefficient . The running resistance is large, resulting in the tape tension , drive power and energy consumption increases.
2, the tape strength is low , a short length single
Steel cord conveyor belt traction components are easily damaged , higher prices, the cost accounting package tape machine for about 50% . Tape strength level of quality of the

merits of the tape machine uptime , productivity and economic efficiency has a direct impact . Thus, with the open pit mining industry

The development of the world are working to improve the strength of steel cord belt and quality , and achieved good results.
3 , the main components of insufficient strength and rigidity . In the domestic mining production, the steel cord belt conveyor roller Jane , racks, tensioning device , the

braking device , feeding device and the drive unit and other components , there had been cracking, severe vibration and failure problems . There are not enough monitoring device

Perfect , affecting the transportation system to work properly. Especially in the feed point , because the funnel device design and tuning is not ideal, when the material comes

into contact with the tape by feeding a strong impact , especially when transporting container material , large blocks of material , the impact is more serious. This material

impact

Tape will be cut , smashed with a core , reducing tape strength and service life . It would also exacerbate the hopper internal wear and mechanical damage, reduce equipment

life.
4, the conveyor belt skidding serious
