the calculation results can however differ from our calculation programme b_rex (free download on the internet under www.siegling.com). these differences are a result of the basically different approaches: whereas b_rex is based on empirical measurements and requires a detailed description of the machine, the calculation methods here are

selection and design of belt conveyors — code of practice (first revision ) 1 scope 1.1 this standard provides guidance for selection and design practices to be adopted for belt conveyors. 1.2 this standard applies to stationary and shiftable and/or extendable conveyors handling loose bulk ma-terial and such material, which behave as solids. for
provide information for alternate conveyor designs. basic power requirements the horsepower, hp, required at the drive of a belt conveyor, is derived from the pounds of the effective tension, t e , required at the drive pulley to propel or restrain the loaded conveyor at the design velocity of the belt v, in fpm: (1) to determine the effective tension,
24/05/2004 dunlop conveyor belt design manual page 6 of 33 the effective tension is the sum of these four components te = tx + ty + tz +tu tx = 9,8g x fx x lc tz = 9,8q x h various conveyor accessories that add resistance to belt movement are standard on most conveyors.

belt breaking strength: this parameter decides the selection of the conveyor belt. the belt breaking strength can be calculated as: bs= (cr*pp)/ (cv*v)…………..eqn.1.7. where, bs is in newton. cr = friction factor. cv = breaking strength loss factor. pp = power at drive pulley in newton. v = belt speed in m/sec. an example of conveyor belt calculations
• preferred belt specification – leave this as no preference if it is unknown or you would like the program to make a recommendation. otherwise, select a belt from the drop-down list. the carcass weight, elastic modulus, and minimum pulley diameters are per table 7.39 in cema’s “belt conveyors for bulk materials, 7th edition”.

5 conveyor pulley selection guide pulley/core diameter – the outside diameter of the cylindrical body of a conveyor pulley, without coating. finish diameter – the outside diameter of a coated pulley (core diameter + 2 times the coating/wrap thickness). face width – the length of a pulley’s cylindrical body.this area is intended to act as the contact surface for the conveyor belt.
calculation of conveyor speed. conveyor speed can be most conveniently calculated, by use of the nomographs supplied on pages. to use this nomograph – first locate the two known values (screw diameter, and required capacity, in cu. ft. per hour), then with a straight edge connect these two points.
ears. belt conveyor is one of the main transport equipment in coal mine, driving drum and belt is its key part. friction principle is used to initiate mechanical drive for belt conveyor. so friction is the driving force. in order to raise transportation efficiency of belt conveyor, driving force of
use of belt conveyor as a method of conveying satisfies the above selection criteria. this article aims at providing a complete solution for design of belt conveyor system to one of the actual raw materialconveying problem. the basic components of a belt conveyor system are shown in fig 8.1. fig. 1: basic drawing of a belt conveyor ii.
design of a conveyor is the speed of the belt, in relation to the required conditions of transport. from the speed of the belt and the roller diameter one is able to establish the number of revolutions of the roller from the formula : v x 1000 x 60 644n = ———————— [revs/min] d x π where: d = roller diameter [mm] v = belt
