What is EP in conveyor belt?
EP conveyor belt is also called polyester conveyor belt(NP conveyor belt in the U.S), the “EP” is short for Polyester fabric, which includes polyester toward longitudinal(warp) and polyamide for latitude(weft), EP fabric plies are sandwiched between rubber skim coats for adhesion and load support, bottom and top cover …
What is conveyor belt rating?
Conveyor Belt-Tension Rating Each belt is rated as to its strength – the amount of pulling force that it will withstand. The strength of a belt (or more accurately, the tension it is able to withstand) is rated in the United States in Pounds per Inch of Width, commonly abbreviated as PIW.
How do you calculate conveyor belt capacity?
CAPACITY (TPH) = . 03 x Belt Speed (FPM) x material weight (lb. per cu. ft.)
What does PIW mean for conveyor belt?
pounds per inch of width
To is the total operating tension, or commonly called Allowable Working Tension, and is expressed in PIW (pounds per inch of width). To is sometimes referred to as TL. Additional tension must be added to the Effective Belt Tension to prevent belt slippage on the drive pulley.
What is nn in conveyor belt?
NN belt is the combination of Nylon in warp and weft and it is widely used in multi-ply conveyor belts for transporting bulk or lumpy materials.
What is trough angle?
A short curved section of a shaker conveyor trough inserted in a trough line to change the angle of direction. Up to 15 degrees of turn, the angle trough does not employ any means of support other than connection to adjacent troughs.
What is the thickness of conveyor belt?
REGULAR standard conveyor belts width sizes in different thickness produced (mm) : 500, 600, 650, 800, 1000, 1200, 1400, 1600, 1800, 2000. Conveying Carrying Capacity of 800 mm width conveyor-rubber-belt is approximately 140 tons per hour at belt speed of 45 meter / minutes.
How do you specify a conveyor belt?
Your load should be the right size for your belt and fit comfortably on it. If it weighs too much for the conveyor’s specifications, it may fail to convey, convey slowly or even damage your drive. Conveying an item with sharp edges or protrusions can damage a belt when it’s not specified to handle that abuse.
How do you calculate torque for a conveyor belt?
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
What is PIW tension?
PIW means “Pounds Per Inch of Belt Width” in RMA American standard, described as EP(“PN” in the U.S) rubber conveyor belt’s “Max. The PIW figure is indicating the working tension an EP rubber conveyor belt is intended to be used for, irrespective of the breaking strength of the splice.
