May 30, 2017 the inspection and testing of belt-conveyor scale systems. Consider the diagram of a simple conveyor belt in Figure 1 below. As one would likely expect, an appropriate amount of friction must be maintained between the conveyor belt and the drive pulley to transfer the motion from the drive pulley to the belt.

If, for example, T2 1,000 lbs, in the case of a counterweighted take up, the weight of the counterweight must be 2,000 lbs. That is because the 2,000 lbs provided by gravity will be resisted with an equal and opposite force of 1,000 lbs in each of the two strands of conveyor belt.

The wrap factor can be as small as 0.08 for dual drive systems with rubber-lagged drive pulleys, an automatic take-up, and 420 of wrap angle, or as large as 1.2 for a single drive system, an unlagged pulley, manual take-up and 180 of belt wrap. Next it is important to calculate T2 sag slack side tension required to prevent belt sag. Sag ...

Other styles of take-up frames are available but all use threaded rod to provide adjustment to the tail pulley assembly. As shown in figure A tension applied to the conveyor belt is accomplished by turning the adjustment nut on the take up assembly. There is another identical take up unit located on the opposite side of the take-up pulley.

Belt Widths The belt widths are as follows 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

Notes As a rule of thumb, the maximum angle for conveying cardboard boxes is 25 degrees. If conveying plastic containers, 15 degrees is typically the maximum incline. The conveyor can be inclined up to 30 degrees. Use our Box Tumbling Calculator to find the maximum incline angle for your containers. You may also be interested Incline Conveyors.

TAKE-UP LOCATION This is the take-up location as a percentage of the horizontal centers of the conveyor. The 0 location is at the head and the 100 location is at the tail. This will normally be 100 for a fixed take-up head drive conveyor profile. The program defaults to the conveyor midpoint for gravity take-up profiles.

Without a tension take-up device, there would be no pressure on the drive drum and the conveyor belt would stop. While this concept is simple, how the tension take-up mechanism is designed to carry out this process can be quite complicated. And, if not done properly, can lead to a variety of resource-draining maintenance problems, including
