Transportation machinery for use by end-use can be divided into sub

1 , bulk material handling machinery ( such as: conveyor screw conveyor bucket elevator steep conveyor , etc.)
( 1 ) by a drive belt conveyor conveyor belt tensioning device composed of the central frame and roller conveyor as traction
And bearing member , whereby heat exchange manufacturers continuous conveyor catechesis materials or chemicals into pieces .
A friction drive conveyor transported materials in a continuous mechanical . Applications it can be material in a
Given conveyor line , from the initial point to feed the final discharge point between the formation of a material transport processes . It can
Conveyed granular materials , can also be transported into pieces items. In addition to the purely material handling , but also can
And request the production process of industrial enterprises in the process of cooperating to air to water heat exchanger form a rhythmic flow transport line . The
Conveyor is widely used in a variety of modern industrial enterprises .
Underground tunnel in the mine , mine ground transportation systems , open pit and concentrator , the widely used transmission belt
Sending machine . It is used for horizontal or inclined transportation transport .
Universal conveyor from the conveyor belt, roller , roller and drive , brake , tension , bend , loading, unloading,
Cleaning and other equipment components.
① conveyor
There are two commonly used with rubber bands and plastic . Rubber band applied between the working environment temperature -15 ~ 40 ° C. Matter
Material temperature does not exceed 50 ° C. Transported upward inclination of Granules 12 ° ~ 24 °. For large transmission angle tread rubber available
Tape. Plastic belt with oil, acids, alkalis , etc., but for the poor adaptability to climate , slippery and aging. Bandwidth
Is the main technical parameters of belt conveyors.
② roller
Of single drum ( tape wrap angle on the drum 210 ° ~ 230 °), double drum ( wrap angle of 350 °) and multi- roll
Tube ( for power ) and so on. There grooved rollers , flat -shaped roller , spherical roller, roller buffer . Trough roller ( from 2
~ 5 rolls composition ) supporting bearing branches for conveying granular materials ; aligning to adjust the lateral position of the belt idler
Avoid deviation ; buffer roller mounted in place by the material in order to reduce the impact of the band 's material .
③ drum
Minute drive rollers and idler pulley . Drive rollers of the main power transmission member . Of single drum ( tape on the drum
The wrap angle of 210 ° ~ 230 °), double drum ( wrap angle of 350 °) and multi- cylinder ( for power ) and so on .
④ tensioning device
Its role is to enable the belt to achieve the necessary tension to prevent slipping on the drive roller, and to the conveyor belt between the roller
Deflection guarantee within the specified range.
Conveyor technology advantages
The first is its reliable operation. In many important production units require continuous operation , such as the transport of coal power plants ,
Conveying bulk materials steel mills and cement plants , as well as loading and unloading of ships in the harbor , are using belt conveyors . As described in these
Occasion shutdown , the loss is huge. When necessary, the belt conveyor can take a class to a group of continuous work .
Conveyor low power consumption . As the material with almost no relative movement of the conveyor belt , not only the running resistance is small (
Scraper conveyor is approximately 1/3-1/5 ) , but also for cargo wear and crushing are small , high productivity . These are favorable
In lower production costs.
Transport conveyor line adaptable and flexible. Line length according to the need. As short as a few meters long can be
Up to 10km or more. Can be installed in a small tunnel above the ground can also be set up in the traffic chaos and danger areas.
According to process requirements , can be very flexible conveyor from the feed point or points by . You can also point to multi-
Several sections or unloading . When simultaneously at several points on the conveyor belt to feed ( such as conveyors preparation plant coal bunker under ) or along the belt
When the longitudinal direction of the conveyor according to any point on the device by feeding a uniform feed to the conveyor , the belt conveyor becomes a
The main transportation trunk .
Reclaimer conveyor can stockpile coal field in the reservoir below the lane when needed , but also the different materials for each heap
Mixed. Material may be simply discharged from the head of the conveyor , can also be moved or plow unloader unloading the transport vehicle
Either with the longitudinal direction of the discharge point .
( 2 ) , commonly known as the auger screw conveyor for granular or powdered material transport level , inclined conveyor , vertical
Other forms of transportation . Transmission distance varies according to deformity , usually from 2 meters to 70 meters .
Transport principles : rotating spiral blades will be the passage of the screw conveyor transported materials . Screw so that the material does not lose
Together rotating blade force is sending its own weight and the screw conveyor enclosure materials for friction materials .
Features: Screw rotating shaft is welded helical blade , blade type , depending on the surface transportation of materials have
Solid surface type , belt face, the blade surface type and other types. Screw terminal helical axis in the direction of movement of materials have
Thrust bearings with material to spiral axial reaction force , the longer the captain , should be added to the intermediate hanger bearings .
There are two pairs of screw conveyor is welded to the screw conveyor shaft of rotation of the rotary blade . Plainly, that is
The organic combination of two screw conveyor , consisting of a screw conveyor .
Screw rotation shaft rotation determines the conveying direction of materials, but generally are designed screw conveyor
Is designed according to the individual rotating conveyor blade . When the reverse transport , will greatly reduce the life of the conveyor .
( 3 ) the use of bucket elevator traction evenly fixed on the endless series of hoppers member, vertical material lifting
Continuous conveyor machinery.
Bucket elevator with throughput , high lifting height , stable and reliable operation and long life significant advantages, its main
Performance and parameters meet JB3926 ---- 85 " vertical bucket elevator " ( referring to the standard equivalent to international standards and foreign
Advanced standards ) , traction ring chain meets MT36 ---- 80 " high-intensity ring chain Mine " , the elevator for conveying powder
Like, non-abrasive and abrasive small and small block granular materials , such as: coal , cement, stone , sand , clay, ore
Stone, because the agency is traction hoist ring chain, thus allowing higher temperature materials transport ( material temperature does not
超过250 ℃). General transport height up to 40 meters.
