1, bulk material handling machinery (eg: belt \ Screw \ bucket elevators \ inclined conveyor)
(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 transport can also be carried into the delivery of items. In addition to the purely material handling, but also with various industrial enterprises in the production process requirements matching process, the 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, acids, alkalis, etc., but the climate and poor adaptability, easy to slip 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 a roller composition) supporting bearing branches for conveying granular materials; aligning roller to adjust the horizontal position with, to avoid deviation; buffer roller mounted in place by the material to reduce the impact of material on the belt. 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. | |||
