the required take-up length is calculated as follows, where. ssp= take-up length (m) l = conveyor length (m) ε = belt elongation, elastic and permanent (%) 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.
it says “this belt will even top the world’s present strongest conveyor belt, a phoenocord st 7800. some 40 years ago, the strongest conveyor belt was an st 4000, used in an underground coal mine in europe (st 4000, the rating as per din 22131, stands for a minimum breaking strength of 4,000 n/mm of belt
conveyor system protection devices the belt conveyor shall be provided with various devices and systems for protecting the system. these devices are used as run-permissive input commands to the general belt control system. the devices must be seen as safety-critical items and for that reason, deserve a high degree of attention and maintenance.
tb = 1.37*f*l*g* [2*mi+ (2*mb + mm)*cos (δ)] + (h*g*mm)…….eqn.1.1. where, tb is in newton. f = coefficient of friction. l = conveyor length in meters. conveyor length is approximately half of the total belt length. g = acceleration due to gravity = 9.81 m/sec2. mi = load due to the idlers in kg/m.
