the sixth edition of the cema belt book belt conveyors for,this presentation looks at the sixth edition of belt conveyors for bulk materials, published in april 2005 by the conveyor equipment manufacturers association (cema). cema is a trade association representing the leading north american manufacturers and designers of conveyor equipment. the purpose of cema is to promote within the industry.belt conveyors for bulk materials calculations by cema 5,belt conveyor capacity table 1. determine the surcharge angle of the material. the surcharge angle, on the average, will be 5 degrees to 15 degrees less than the angle of repose. (ex. 27° - 12° = 15°) 2. determine the density of the material in pounds per cubic foot (lb/ft3). 3. choose the idler shape. 4. select a suitable conveyor belt.

belt conveyors are also a great option to move products through elevations. incline belt conveyors from low to high and decline belt conveyors from high to low. this manual is short, with quick and easy reading paragraphs, very practical for calculations of belt, chain conveyors and mechanical miscellaneous, in the metric and imperial system.
the cema historical method allows the designer to select an appropriate percentage of sag between the carrying idlers, to prevent lumps or material from coming out of the conveyor belt. the three values cema provides are 3%, 2%, and 1.5% sag those percentages are based on material lump size, the proportion of lumps vs. fines, and the idler
