There trough idler roller, flat-shaped roller, spherical roller, buffer roller. Trough roller (composed by three rollers) support branch conveyor carrying produce to transport granular materials; to adjust the lateral position of high quality conveyor belt aligning roller, to avoid deviation; buffer care roll into place by the material, in order to reduce the impact of the band's material. Minute drive rollers and roller bend pulley. The drive roller is the main component of transmitting power. Sub single drum (tape on the drum wrap angle is 210 ° ~ 230 °), double drum (wrap angle up to 350 °) and multi-cylinder (for power) and so on. Tensioning means which act to move the conveyor belt to achieve the necessary tension, so as not to slip on the driving roller, and the conveyor belt deflection roller between guaranteed within a predetermined range. Contains spiral tensioning device, weight tensioning device, Car-tensioning device. The reason for mine belt fire is a fire-prone area of ??the mine main conveyor, due to their sudden, rapid development, pose a threat to the underground workers, and even the spread of fire induced due to the possibility of a gas explosion. Cause of fire is a fire source is sufficient to make the tape burn calories. Skidding accidents are the main factors to generate enough heat conveyor quote skid tape loose due to load large or tape jam caused by tape tension force is too loose and elastic elongation tape generated due to the tensioning device too; large load due to heavy start one, the second is due to the load is too large, and the third is the tape drive rollers, idler roller between the driven friction is too small, as in the tape surface water or oil, driven idler roller bearing damage or damage; tape jammed tape mainly buried in coal or mud, so the tape does not run. Another burst of electrical equipment failure, electrical short circuit may also cause the conveyor fire.
