89 Belt Tension Calculations W b =weight of belt in pounds per foot of belt length. When the exact weight of the belt is not known, use average estimated belt weight (see Table 6-1) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t, K x, and K y, are used in calculations of three of the components of the effective belt tension, T

There are several methods available to the engineer for making trajectory predictions of the path followed by a bulk solid discharging from a belt conveyor. Two methods available are those from the C.E.M.A (1979) and M.H.E.A. (1986) handbooks of recommended practice for belt conveyors, while a third method is presented in the Dunlop Conveyor …
Width and Depth of discharge trajectory, can be verified against CEMA table for load capacity. Phi angle – actual belt approaching angle, instead of belt incline slope angle. Gamma angle – at which discharge of slow speed conveyor trajectory will start. Critical speeds, high and low (the speed range in between is termed mid-speed in ...
SUMMARY This paper presents seven material discharge trajectory methods and explains the differences between them. Most of these methods involve a series of equations to determine first whether low-speed or high-speed conveying condition apply, then the material discharge angle for low-speed conditions and finally the X and Y coordinates …
This page allows you to calculate the discharge Trajectory of the material and print the trajectory co-ordinates.
The angle of repose of a material is the acute angle which the surface of a normal, freely formed pile makes to the horizontal. The angle of surcharge of a material is the angle to the horizontal which the surface of the material assumes while the material is at rest on a moving conveyor belt.This angle usually is 5 degrees to 15 degrees less

The path the bulk material takes as it is discharged from the delivery conveyor is called the trajectory. Trajectory is affected by the speed of the belt, the angle of inclination of the …
Guidelines for the calculation of bulk solid material cross sectional dimensions and the influence of the belt conveyor transition length on the inclination of the trajectory at discharge are well established. However, not a great deal of research has been conducted on the influence of bulk solid material properties and conveyor belt transition geometry …
I'm looking for a little bit of help on how to mathematically determine the trajectory of material off a conveyor belt. Here are the specs (I'm not sure what information would be required) This particular belt carries a heavy grainy particle (Nickel Matte to be exact) that is about 10.5% water by weight.

delta-T 5 Conveyor Design Program. Typical design Report - can be printed or exported to Word®, Excel®, PDF® files and other applications. Belt tensions can be viewed graphically, and the Calc section provides useful procedures for calculating discharge trajectories, vertical curve radii and other frequently performed routines.
Accurately determining the material discharge and trajectory from the head pulley is the first step in this design process. This paper will focus on the determination of the material trajectory as it leaves the belt conveyor head pulley. This process will also determine the point at which the material leaves the belt, referred to as the ...
As a rough guideline, use 1,5 % elongation for textile belts. and 0,2 % for steel cord belts. Note: For long-distance conveyors, dynamic start-up calculations. may be required, because not all elements are set in motion simultaneously, due to the elastic properties of the conveyor belt.
