Continental welded steel conveyor pulleys with a.D. hubs and bushings.,-The 3/4 per foot taper of the 0.0. provides a 32 to 1 locking ratio on the shaft. The advantages of the 0.0. system are its superior holding power in both lateral and tor-sional directions, its ease of assembly and disassembly and its self locking taper.
The procedure for selecting pulleys for a conveyor for any given application involves the evaluation of a number of factors pertinent to the installation Consideration should be given to the following- a) Application / Environment b) Conveyor design 1. Angle of Wrap 2. Belt selection 3. Conveyor duty 4. Belt Tension 5. Belt width
SPIRAL DRUM PULLEY. The PPI Spiral Drum pulley is formed by a pair of vertical steel bars helically wound around a Heavy Duty Drum (HDD) pulley. This unique design is frequently used when additional cleaning action is desired without introducing additional belt vibration. MINE DUTY DRUM PULLEY.
Nov 05, 2020 By employing the standards, the designer uses the maximum belt tension and selected belt carcass as the starting point or criterion. Charts and tables then give him optimum head pulley and bearing sizes, and frame and pulley geometry for any given angle of conveyor inclination, as well as bearing center dimensions.

A pulley is powered by an electric motor to rotate the belt the other pulley is connected to two parallel hydraulic cylinders to move back and forth to create tension load cycles on the belt loop. In 1997, CDI designed and built a dynamic splice fatigue machine that can test the
The tail pulley is located at the end point of the belt conveyor. It comes with either a flat face or a slatted profile (wing pulley), which cleans the belt by allowing material to fall between the support members. 3.Bend pulley. 4.Snub pulley. The Bend Pulley is used for changing the direction of the belt.
