These open or enclosed units will handle nearly any material, regardless of size and bulk density in a reliable and economical manner. The key to the line’s success is its low cost, simplicity and efficiency. There are no augers, bearings or seals which can degrade material, leak or require maintenance. Two highly efficient, externally mounted vibrators provide quiet, linear motion to smoothly move your product into process. Vibra Screw Vibrating Conveyors make an excellent alternative to screw and belt feeders and conveyors.

All material handling systems begin with a thorough review of the particulate solid(s) being handled or processed. Once the flow properties of a solid are quantified, flow problems that occur with a given material can be predicted and handled, preferably in the initial design stage. Understanding a material’s characteristics and how to apply these properties is essential for a safe, efficient and trouble free system.
