How A Chain Conveyor Works
A chain conveyor operates on the principle of interconnectivity: a chain connects each gear, resulting in a smooth conveying process. The chain conveyor has a series of gears connected into a continuous system by the chain. Typically, each gear has teeth which create a free rotational interface with the chain. The arrangement is set in such a ...
Screw Feeders
Normally short in length, Screw Feeders are designed to regulate the volumetric rate of material flow from a hopper, bin or storage unit. The inlet is usually flooded with material ( load capacity) but by incorporating changes in the construction of the flighting (diameter, pitch, etc.) and the speed of the feeder screw, the material ...
