Technical Analysis belt abroad

Conveyor is widely used in a variety of modern industrial enterprises , the development trend of the conveyor so as to be understood by us . Now , the special machinery for your

brief introduction about the advantages of Extendable conveyor the conveyor belt at home and abroad for development and application .
First, the domestic belt conveyor technology status
Our manufacturing conveyor varieties, many types . In the "Eighth Five- Year" period, through the national one-stop " 10 000 t mining equipment ," implementation of the project

, conveyor technology has been greatly improved , coal mine with high-power, long distance belt conveyor

The key technology research and development screw conveyor of new products Lu have made ​​great progress. Such as large- angle distance belt conveyor equipment , high efficient working face

telescopic belt conveyor etc. to fill the gap , and the key technology of the belt conveyor to reduce its main component parts

The theoretical research and product development , successfully developed a variety of soft start and braking device and PLC as the core of the programmable electronic control

devices , variable speed drive system uses hydraulic coupling and planetary gear reducer.
① continue to large-scale development . Large transmission capacity , including large-scale , large single length and large transmission angle and other aspects. Hydraulic

conveyor length reached 440 km or more. Belt conveyor length of nearly 15 km single , and has appeared composed by a number of Taiwan Contact and B two

Land of the " conveyor belt road ." Many countries are exploring long-distance, large capacity continuous transport of materials better conveyor structure .
② to expand the use of the conveyor . Developments in high temperature , low temperature , corrosive , radioactive , flammable substances in the work environment , as well as

capable of delivering fiery , explosive, Pellet , sticky material conveyor.
③ the conveyor structure to meet the automated material handling system to control stand-alone asked for. As used in automated sorting post office parcel trolley conveyor

sorting operation should meet the requirements.
④ reduce energy consumption in order to save energy , the field of conveyor technology has become an important aspect of research . Has one ton material handling energy

consumed by one kilometer conveyor selection as one important indicator .
⑤ reduce all kinds of conveyors in operation generated dust, noise and emissions .
Second, foreign conveyor technology status
Foreign conveyor technology has developed rapidly, which is mainly manifested in two aspects: one is functional diversification of belt conveyor , the application range

expansion, such as high- angle belt conveyors, tubular belt conveyors, space turning belt conveyor and other models ; hand

Is the belt itself has made a huge technology and equipment development, especially long-distance, large-capacity , high- speed and other large conveyor belt has become the main

direction of the development of its core technology is the development and application of a belt conveyor dynamic analysis and monitoring technology to improve the belt conveyor

Machine operating performance and reliability. Abroad has been designed for use or has been a few typical distance belt conveyor conveyor line .  1, Spain, Western Sahara is

the world 's longest conveyor line long distance conveyor line , the line up to 100km, with two and a half hours

Built and put into use in 1972 , used to rocky plateau in cloth . Carat apatite ore open pit transported Yi Era Yong harbor. The total investment amounted to two hundred million

marks . The line is expected to be able to reach the line for 30 years, the average annual transport capacity of 10 million tons of apatite ore (2000t / h

) . The entire line by the length of 6.9 ~ 11.8km conveyor consisting of 11 units . Bandwidth l000mm, using ST3150 -type steel cord belt , a belt speed of 4.5m / s.  2, just

that mine 20km ground conveyor belt system to represent the level of development of a modern transport

Line . The delivery system consists of a length of 10.3km flat cornering and a 10.1km line conveyor belt long form . Turning radius of curvature of the belt conveyor 9km  arc

length 4km. Two conveyor line parameters, in addition to other parameters are the same   transport capacity

Of 2200t / h  Bandwidth 1050mm  belt tensile strength of 3000N/mm  safety factor of 5  tensioning device for the hammer taut. Allow stroke 25m, driven by three sets

700KW DC motor, double drum drive . System uses an advanced technology manufacturing and installation of roller , horizontal

Turning technology and dynamic analysis techniques.  3,15.6 km horizontal bend cross conveyor and put into use in 1996 , is the world 's longest single belt conveyor . The

conveyor will ZISCO of NewRippleCreek mine through secondary crushing of iron ore shipped to Zimbabwe

Steelworks nearby. Transport capacity of dry ore 500t / h, wet ore 600t / h. System length of 15.6km, material lifting height of 90m. Recent years, China 's large belt conveyor

design, manufacturing has also been considerable progress.
From the late 1960s has been the production of more than 200 steel cord conveyor in coal, phosphate , iron ore and port to use . Length up to 7602m where a large single belt

conveyor has been put into use. Currently, including the length of the conveyor line l0km and several other long-distance band

Conveyor systems are being designed or planned .
