Vibrating Feeders

The vibrating feeders or conveyors, driven by electro- magnetic vibrators or synchronously contra rotating vibrating motors, provide almost maintenance-free and low-wear operation. Our vibrating conveyors have now been used for horizontal and vertical conveying of various products under the most varied operating conditions. Vibrating conveyors can be used even under extreme environmental conditions (e.g. handling of materials at 900°C, at ambient temperatures down to -50°C, under exclusion of air or in a vacuum).
Vibrating trough and tube conveyors open or enclosed troughs and tubes of various types made of standard or stainless steel, or of special materials such as Hastelloy or titanium, are used for material handling. Highly flexible coil springs or rubber cushion elements provide elastic support or suspension. High degrees of vibration insulation and smooth operation can be achieved by means of structure-borne noise elimination. The conveying process itself is based on the vibration of the conveyor deck at a slight angle to the plane of conveyance. The material to be conveyed is moved in microscopic throws, so the vertical acceleration exceeds the acceleration due to gravity. Free-swinging vibrating conveyors of simple design are available for conveying distances up to about 7m. These are very popular in GLASS INDUSTRY.
In addition to vibrating conveyors used as batching system we also supply ER batching trough conveyors specially designed for even batching of bulk materials into mixers, grinders, weighers and processing equipment. The Series ER features a modular design making it possible to combine driving block, trough and feed hopper in different ways. The electromagnetic drive systems and vibrators mainly used in these applications provide almost maintenance-free and low-wear operation. The associated electronic control systems with linearized control characteristics and voltage stabilization can be driven by 4-20 mA or 0-10 V input signals for incorporation into control circuits.
