Join Us nowSlack-side tension-The area of least tension on a conveyor belt; the low-tension areas will vary on the location of the snub and take-up pulleys; they are completely dependent on the individual conveyor and must be identified for each application. Slider bar-A low-friction bar, typically used in the construction of a slider bed belt-support cradle.
Join Us now2021-9-29 · Each pulley must withstand the forces imposed by both belt tension and conveyed load depending on the position that they occupy in a belt conveyor. It is necessary to specify following data: – belt width – diameter of drum in relation to the belt type and characteristics – type of lagging
Join Us nowPulleys with their axes at other than 90° to the belt path will lead the belt in the direction of the edge of the belt which first contacts the misaligned pulley. When pulleys are not level, the belt tends to run to the low side. This is contrary to the old "rule of thumb" statement that a belt runs to the "high" side of the pulley.
Join Us nowWhen tension measuring load cells or scales are used, they are rigged to measure the pull on the take-up pulley. The belt is pulled until the load cells or scales register a tension equal to or slightly greater than the recommended take-up force. Make allowance for an amount of belt necessary to correctly position the counterweight from this point.
