Its function is to make the belt reach the necessary tension, so as not to slide on the drive drum, and make the belt in the roller between the deflection within the specified range.
Separate drive drum and reverse roller. Drive drum is the main part of power transmission. Single drum (tape wrapped angle of 210 to 230 degrees), double drum (angle of 350 degrees) and multi drum (for high power).
Single drum (tape wrapped angle of 210 to 230 degrees), double drum (angle of 350 degrees) and multi drum (for high power). There are groove shaped roller, flat roller, self-aligning roller, cushion roller. Trough roller (composed of 2 ~ 5 rollers) supporting bearing branch, used for conveying bulk materials; self-aligning roller with lateral position, to adjust the belt to avoid deviation; the buffer roller attached to the material, to reduce the materials on the impact of.
There are two kinds of rubber belts and plastic belts. The rubber band is soft, so it bends. The rubber belt is suitable for working environment temperature -15 ~ 40 degrees C between. Material temperature shall not exceed 50 degrees C. The angle of upward conveying of loose aggregate is 12 to 24 degrees. For large dip angle conveyor, rubber belts are available. Plastic belt has the advantages of oil, acid and alkali, but it is easy to skid and aging because of its poor adaptability to climate. Bandwidth is the main technical parameter of belt conveyor.
Hello, general conveyor belt conveyor belt, roller, roller and drive, brake, tension, modification, loading, unloading, cleaning and other devices.
