Specializing in the production of belt conveyor tail drum scalable, belt conveyor, including uninstall drum, storage with positions and positions within the bend pulley, tensioning rollers and tensioning device, drive pulley, conveyor belt, tail drum , characterized in that: the conveyor belt wraps around the head from the tail drum unload the drum to carry the materials from the unloading roller first wound into the deflector drum and the tensioning drum of the stocker position, after the wound into the drive rollers, and finally around the back The tail rollers forming a closed loop. The structural arrangement is reasonable, warehouse layout of the reservoir with in the minimum tension zone of the conveyor belt, and the bend pulley with reserve positions can and taut the drum affected by the minimum force pull tensioning device required minimum supply ore wheel mine wheels inside the mine wheels have left a certain gap between the rim, the rim and the rails. Wheels in contact with the rail tread surface tapered, so that the wheel maintained in orbiting, reducing mechanical wear and to reduce running resistance. Our company can produce the processing of various models the tramcar and mine wheel, for example: 600 gauge diameter of 300 mine wheels, 600 gauge diameter of 350 mine wheels, cast steel, cast iron, all kinds. φ200-600 ore wheels, φ300-600 on mine wheels, φ350-900 mine wheels on mine wheels, the tramcar pin, tub meet tricyclic chain company can produce processing of various models the tramcar and mine wheel such as: the 600 gauge diameter of 300 mines wheel, 600 gauge diameter of 350 mine wheels, cast steel, cast iron, all kinds. Mine wheels are suitable for various tramcar, steel products, quality assurance, and first-class service. SGB-620-40T scraper conveyor to SGB620/40T for scraper conveyor which parts?
