Classification of bulk material handling machinery and Uses

(A) by a conveyor belt tensioning device drives the central structure and composition of the roller conveyor as towing and carrying member, so as to continuously fed into pieces

scattered and fragmentary materials or goods.
    Friction drive conveyor is a continuous manner for material transport machinery. Apply it, the material can be transported in a certain line, the feed point from the initial

to the final discharge point between the formation of a material transfer processes. It can be granular material conveyor can also be

For a delivery of items. In addition to the purely material handling, but also with various industrial enterprises in the production process requirements matching process, the drag chain conveyor

formation of the rhythmic flow transport line. So conveyor is widely used in a variety of modern industrial enterprises.
    In the underground mine workings, mine ground transportation systems, open pit and processing plant, widely applied conveyor. It is used for horizontal transport or inclined

transportation.
    Universal conveyor from the conveyor belt, roller, roller and the drive, brakes, tension, bend, loading, unloading, cleaning and other equipment components.
    ① conveyor
    Commonly used with two kinds of rubber bands and plastic. Rubber band for working environment temperature -15 ~ 40 ° C between. Material temperature does not exceed 50 °

C. Upward transport of Granules inclination 12 ° ~ 24 °. Available for large transmission angle tread rubber band. Plastic belt with oil, acid,

Alkali, etc., but for the poor adaptability to climate, slippery and aging. Bandwidth is the main technical parameters of belt conveyor.
    ② roller
    Of single drum (tape on the drum wrap angle of 210 ° ~ 230 °), double drum (wrap angle of 350 °) and multi-cylinder (for power) and so on. There trough roller, flat-

shaped roller, spherical roller, buffer roller. Trough roller (2 to 5 by the roller composition) supporting bearing branches

For conveying granular materials; aligning roller to adjust the lateral position with, to avoid deviation; buffer roller mounted in place by the material in order to reduce the

impact of material on the belt.roller chain conveyor
    ③ drum
    Minute drive rollers and bend pulley. Drive rollers are main components of power transmission. Of single drum (tape on the drum 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 achieve the necessary belt tension, in order to avoid slipping on the drive roller, and to the conveyor belt between the deflection rollers ensure that the

required range.
    Belt conveyor technical advantages:
    The first is the conveyor reliable operation. Require continuous operation in many important production units, such as the transport of coal power plants, steel mills and

cement conveying bulk materials, as well as loading and unloading of ships in ports all adopts belt conveyor. On these occasions, such as downtime, the loss

Is huge. If necessary, take a class to a group of belt conveyor can work continuously.
    Conveyor low power consumption. As the material almost no relative movement of the conveyor belt, not only the running resistance (about 1/3-1/5 scraper conveyor), but also

the wear and broken cargo are small, high productivity. These are conducive to lower production costs.
    Conveyor belt conveyor line adaptable and flexible. Line length according to need. Short as a few meters, length up to 10km or more. Can be installed in a small tunnel,

ground transportation can also be set up in the region over the chaos and danger.
    According to process requirements, can be very flexible belt from one or more points by the material. Also provide multiple discharge points or several sections. While

simultaneously at several points on the feeding conveyor (such as the Coal bunker conveyor) or along the length direction of the belt at any point

By uniformly feeding equipment to feed conveyor, the belt has become a major transport route.
    Coal stockpile conveyor can stockpile reclaimer roadway below, when necessary, but also to the heap of different materials are mixed. Materials may be simply discharged from

the conveyor head, but also by moving plow unloader or unloading vehicle longitudinal direction of the belt at any point discharge.
    (2) commonly known as the auger screw conveyor is suitable for granular or powdered materials horizontal conveyor, inclined conveyor, vertical transportation and other

forms. Transmission distance varies according to deformity, usually from 2 meters to 70 meters.
    Conveying principle: rotating spiral blade for screw conveyor passage of the material transported. So that the material does not rotate together with the screw conveyor

blades is the material force of its own weight and the frictional resistance of the material conveyor chassis.
    Features: Screw rotating shaft is welded spiral blades, blade face delivery of materials based on a solid surface different type, belt type face, leaves and other types of

face. Screw conveyor screw axis in the direction of movement of the material with the thrust bearing to the terminal with the material to spiral

Axial reaction force, the captain longer, should be added to intermediate hanger bearings.
    Two screw conveyor is to have two rotating blades were welded with the rotary shaft screw conveyor. To put it plainly, is to two conveyor organic combination, consisting of

a screw conveyor.
    Screw rotation axis of rotation, determines the conveying direction of the material, but generally in the design of the screw conveyor are transported in accordance with the

individual blades of rotation. When the reverse transport, it will greatly reduce the service life of the conveyor.
    (3) bucket elevator: the use of uniform traction member fixedly connected to the endless series of hoppers, vertical continuous upgrading of materials handling machinery.
    Bucket elevator with transmission capacity, high hoisting height, stable and reliable, long life and significant advantages, its main properties and parameters in line with

JB3926 ---- 85 "vertical bucket elevator" (with reference to the standard equivalent to international standards and foreign advanced standards), traction ring

Chain compliance MT36 ---- 80 "high-intensity ring chain mine," the elevator for conveying powder, granular and small block of non-abrasive and abrasive small materials, such

as: coal, cement , stone, sand, clay, ore, etc., because the traction hoist ring chain is due to

This allows the delivery of high temperature materials (material temperature does not exceed 250 ℃). General transport height of up to 40 meters.
