The idler, which is one of the core components of belt conveyors, will eventually be installed in various conveying equipment. The installation of conveyor idlers requires calculation of the idler spacing distance. So how to confirm and design the spacing distance between the idlers of belt conveyors? The idler spacing in the conveyor belt should be designed to take into account various factors such as the sag of the conveyor belt, the bearing capacity of the idler bearings, the characteristics of the material, the width of the conveyor belt, the inclination of the conveyor, and the actual operation. The method for determining the spacing distance between the idlers of the belt conveyor is described in detail below.
The increase in the number of idlers does not only increase the huge investment, but also increases the running resistance of the conveyor, which will cause the specifications of the conveyor belt and the power of the motor to increase. By rationally determining and optimizing the distance between the idlers of the belt conveyor, the amount of idlers can be greatly reduced, which has obvious advantages. If the number of idlers is reduced half, equipment investment will be greatly reduced. The reduction of the number of idlers reduces the running resistance of the conveyor, reduces the power consumption, and saves electrical energy. Due to the large amount of belt conveyor idlers, it is prone to failure. Therefore, the reasonable arrangement can reduces the amount of idlers, reduces the maintenance workload and costs, extends the life of the conveyor belt, reduces the deviation rate of the conveyor belt, and improves the reliability of the operation of the conveyor equipment. Therefore, under the premise of ensuring the reliable design, the proper design of the gap between the idlers can not only reduce the number of idlers, but also reduce the investment cost of the belt conveyor.
We list the carrying idler spacing and return idler spacing distance below. You can learn how to confirm the conveyor trough idler spacing, return idler spacing, and carrying idler spacing here.

The belt conveyor is used to transport bulk materials has a distance between the supporting idlers about 0.8-1.5m and a distance of the return idlers of the rollers of about 2-3m.
For long-distance belt conveyors (overland belt conveyor), the method of increasing the spacing between the idlers is generally adopted some manufacturers to reduce the total resistance. The spacing distance between the upper carrying idlers can be increased to 2.5 to 5.0m, and the spacing distance between the lower return idlers can be increased to 5 to 10m. However, this design must be based on sufficient dynamic analysis to ensure reliable conveyor operation.
Generally speaking, when conveying finished goods with a weight of more than 20kg, the distance between the idlers is changed not more than 1/2 of the length of the finished goods (along the conveying direction). The distance between the idlers of the finished goods less than 20kg can be 1m.
Due to the different tension and volume of each point of the belt conveyor, the maximum allowable distance between the idlers is also different, and the arrangement of the idlers at equal intervals does not consider the specific conditions of each conveyor part, it can meet the real application by using different spacing idlers on the same belt conveyor. Unequally spaced belt conveyors can effectively reduce conveyor investment costs.
