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
Eng. Guide Index The Dragon-Flite conveyor is an efficient, high performance alternative to conventional means of material handling. Because the material is moved En-Masse, horsepower requirements can be as much as half of that of alternative means of conveyance. The Horsepower (HP) requirements of a Dragon-Flite conveyor can be

Inclined Screw Conveyors Inclined screw conveyors typically operate from slightly above the horizontal position to 45 degrees from the horizontal position. Above 45 degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the CEMA guidelines for vertical screw conveyors.

A belt conveyor is a conveyor in which the product rides directly on the belt. The belt is supported by either a roller bed conveyor section or a slider bed conveyor section. This manual will explain the various types of Mathews’ belt conveyors. This manual describes the following types of belt conveyors: 1. Horizontal Belt Conveyors 2.
Chain speed, normally calculated in feet or metres per minute, is a critical consideration in determining the conveyor capacity. It is in considering this parameter that conveyor chain pitch and conveyor chain drive and idler sprocket can be determined. fig. 5.1 illustrates the relationship between speed, chain pitch and sprocket size.
