It is accomplished by the addition of at least three rollers to the underside of the conveyor. An example of this mechanism is shown below (Figure D). Belt tension is achieved by a connection of a pneumatic cylinder or a spring-loaded device to the lower tension roller. The cylinder will pull the lower roller down, which places tension on the belt.
Movable belt conveyor, also known as belt conveyor, it is divided into two types of electric lifting type and non-lifting type.It is used to convey corn, wheat, grain, sack, river sand, gravel, fine sand and truck loading, etc. The machine has the characteristics of large conveying capacity, low lattice, flexible movement, simple operation, safe and reliable use, good maneuverability and so on.
Tensioning Devices of Conveyor Belt. Constant force tensioning device. When the conveyor belt is lengthy or the weight of the transported good is great relative to the force/elongation ratio (elastic modulus) of the belt, or load is rapidly fluctuating, a constant-force
Tensioning a Belt. If the tension on the conveyor belt needs to be adjusted, start with the conveyor empty of products and tension the belt until it does not slip. Begin to add product and tension the belt as needed until the conveyor will move the heaviest load without the belt slipping. When the belt is no longer slipping, stop the conveyor and place a full product load on it. Restart the conveyor and check for belt
Tension Control In Underground Conveyors 11 Tension Control in Conveyors Belt tension is a critical component in conveyor design It limits the amount of load that a conveyor can carry and is important in transferring the power from the driving force into the belt via friction On Beltconveyor Scale Systems
The endless belt is pulled from the spiral with sufficient tension to hold the belt against the chain to minimize slippage at the belt/chain juncture as a result of positive link engagement between the drive chain and the edge of the conveyor belt. Control of tension is effected by a DC motor acting as a torque controlled output rather than a speed controlled output. Tensioning adjustment permits effective

In a related move toward safer, more productive material handling, one global conveyor technology innovator has introduced an automated pneumatic tensioning system for belt cleaners. The new device delivers precise monitoring and tensioning throughout all stages of blade life, minimizing the labor typically required to maintain optimum blade pressure and extending the service life of both the belt and the cleaner. Equipped with sensors to confirm that the belt
Enclosed Conveyor Belt Tensioners Prevent debris buildup, and thread damage— these tensioners have a totally enclosed adjusting screw. Tensioners mount to the sides of the conveyor and attach to the bearings that hold the pulley. Note: Two tensioners and
Correct initial elongation for conveyor and drive belts. There are a few basic prerequisites which must to be met before a conveyor or flat belt can be correctly installed. Correct installation comprises the following steps: Checking the system, installing the conveyor belt, and finally, start-up and alignment.
tensioning the belt at the take-up end of the conveyor (end opposite drive). (Fig. 9) Tensioning Belt Adjust the belt so it is tight enough to remove excess slack from the belt. Enough tension is needed to ensure that the belt tracks properly and does not slip on the drive roller. (Fig. 9)
Conveyor Belt Tensioning Systems For Mining and Ship-Loading Applications. Timberland has extensive experience with conveyor systems operating in the difficult operating environments of coastal mine sites and the oil sands of the Canadian north. We have designed complete conveyor tensioners ranging in length from 100 m to several kilometers, including winches, controls, sheaves and integrated load

Vehicle type tensioning device of the belt conveyor is that the tail wheel is mounted on a moving vehicle. The reversing pulley is connected by wire rope, and it is respectively connected to mobile vehicles and heavy hammer, by the effect of gravity, the hammer will cause automatic tension of conveyor belt.
Overland Conveyor Tensioning Winches. Torque Systems Inc. offers winches that are used for tensioning ore-handling conveyors. They are electric motor driven with wire rope drums for tensioning one or more wire ropes. These winches provide a compact, reliable tensioning system that can be readily integrated into automatic control of conveyor tension. In fact, mining companies around the
The tension of a conveyor belt is determined by feel. It is important to make sure that the driving pulley can drive the belt without slipping even under a maximum load. The minimum and maximum admissible initial elongation (initial tension εo) varies according to the elements of traction.
