Troughed Belt conveyors are most widely used and efficient means of moving bulk materials. The belt is supported on slider deck or rollers mounted at 20°, 30° or 45°, two, three of five roller Troughed form.
They offer an efficient and excellent means of transporting materials that are meant for transportation in bulk, over small or large distances continuously.
Troughed belt conveyors can take numerous forms and are being used in many different applications with tremendous success.
For clients who want to go for troughed belt conveyors, it is very important to draw a distinction between bulk handling of materials and unit handling.
'Unit handling' is generally described as discontinuous as this involves the transportation of for example, packed boxes, filled bags of cement and so forth.
Whereas troughed belt refers to the transportation of particulate products on a continuous basis like conveying of lumpy ore from a mine to a processing plant or for transporting coal from a stockyard to a bunker above a crusher. Such types of conveyor belts are mostly used in mining industry.
Such types of belt conveyors comprises an endless, rubberized flat belt suspended between pulleys at either end and supported along its length by a number of rotating idler rollers. The belt is driven via one head pulley and the tension in the belt is maintained by using a sliding pulley which is tied to a gravity take-up unit.
The material is then loaded onto the conveyor at the tail-end via a chute and is transported along the carrying-side to the head-end where it discharges into a discharge chute which guides the product onto the downstream equipment.
In such types of conveyors, impact idlers are located at the loading point to support the belt where the load impacts onto the belt as it is dropped down the loading chute.Download Pdf
