Volumetric screw feeders are a commonly used method of metering bulk materials into a process with reasonable accuracy. They utilize an auger, oriented in the horizontal position, driven by a motor with a variable speed drive to feed material at a controlled rate. In order for the auger flights to remain full the feeder is fed by gravity from a hopper mounted above the auger. This hopper must be filled by another means, often a bucket elevator. Typical accuracy rates of 2-5% error at 2 Sigma are realized with volumetric screw feeders.
An OLDS ELEVATOR™ can perform the same functions as a volumetric screw feeder while eliminating the need to elevate material to fill the feed hopper. The OLDS ELEVATOR™ simply takes the material from floor level, elevates and meters it directly into the process. One OLDS ELEVATOR™ does the job of two pieces of conventional equipment. And the accuracy of the OLDS ELEVATOR™ meets or exceeds that of conventional volumetric screw feeders. Typical accuracy rates of 1-3% error, at 2 Sigma are realized with OLDS ELEVATORS™.
