Most modern production facilities combined with an exemplary quality assurance system including ISO 9001 certification, as well as trail-blazing test equipment for practice-oriented product engineering, in connection with an experience in conveyor belt technology going back to an origin of 100 years ago, are the foundation of the highest level of economy of Phoenix conveyor belts. In this brochure Phoenix offers the interested specialist a document for calculating and designing conveyor belt systems. The principles which deal with power requirements and belt tensions, belt strength and tractive power distribution over the belt width, additionally deal with transition zones and vertical curves. The subsequent chapters describe special design interpretations for the conveyor belt and its essential components, as well as for the required belt tracking. An extensive tabulated section at the back of the brochure comprises all of the details which are essential for the calculation and design of belt conveyor systems. The principles of calculation are mainly based on DIN 22101 which appeared in the August 2002 edition. Where complex calculations are involved, modern Phoenix computer programs can be availed of. We thus recommend to complete and to return the questionnaire (see chapter 6) enclosed in this brochure. The Phoenix specialists’ know-how and experience will ensure the optimum conveyor belt design to be selected. Do not hesitate to utilize the experti
