Sibur exports to China include polyethylene, nitrile rubber and butyl rubber. Sibur company achieved sales revenue of more than 934 million euros in Asia in 2010.
Belt conveyors are the main transportation equipment for coal preparation plants and mines. Common belt conveyors include general-purpose belt conveyors, patterned belt conveyors and wire rope belt conveyors. According to the installation characteristics, it can be divided into fixed belt conveyor and movable belt conveyor. Coal preparation plants and mines mainly use fixed belt conveyors.
Large conveying capacity and low power consumption. When the belt conveyor is working, there is no relative movement between the conveyor belt and the material, so that it will not cause large wear and tear due to the increase of the transportation speed. Since there is no friction with the material, its power consumption is small.
The conveying distance is large and easy to arrange. The conveyor belt is a flexible member, which has the characteristics of strong adaptability to the transportation slope, and is easy to be arranged in a curved shape. It is easy to arrange the loading and discharging of the belt conveyor when the working site is uneven. The loading and discharging interface can be set at any position.
Working principle of belt conveyor
Belt conveyor is a continuous conveying equipment with flexible tape as material carrier and traction. According to the principle of friction, it is carried away by movement. The drive roller drives the tape to transport the material to the required place. The tape goes around the active roller at the head and the reversing roller at the tail to form a stepless link belt. Give the tape the tension required for proper operation. When working, the active roller drives the tape to run through the friction between it and the tape, and the material moves together with the tape on the tape. The belt conveyor produced by Kunwei Machinery generally uses the upper belt to transport the material, and the special discharge device at the end is used to discharge the material at any position.
