From heavy-duty electromechanical to precision-critical electromagnetic vibrating feeders,
JVI designs the solutions for your bulk material processing needs.
Vibratory feeders transport and regulate feed rates for bulk material processing across a broad range of applications and industries. JVI Vibratory Feeders handle bulk materials including heavy quarry product and metal alloys; food and candy; plastics, glass, grain, and more. Available with electromechanical motors or electromagnetic drives and always customized to your application requirements.
Electromechanical Vibratory Feeders
Electromechanical vibratory feeders, powered by electromechanical drives, are preferred for medium to very heavy-duty applications and are well suited to 24/7 operation. Electromechanical drives imply an unbalanced weight on a rotating shaft. This type of drive can be in the form of an electromechanical motor, a gear box exciter or an unbalanced shaft. The drives are configured on vibrating feeders to produce a constant material velocity.
Electromechanical Pan Feeders regulate bulk material flow rates up to 4000 TPH, featuring enhanced single mass technology. Preferable in high-volume applications, such as discharging bulk storage, surge hoppers, and bins and feeding belts in reclaim tunnels. They are ideal for use upstream of screens, crushers, and mills, where spreading material evenly and regulating flow improves process control and equipment life.
Electromechanical Tube Feeders excel at regulating flow and discharging hoppers into downstream equipment at precise rates. Used for small work envelopes and enclosed feeding, they are an ideal alternative technology to screw feeders. With no internal moving parts, tube feeders do not degrade or breakdown materials while they are being handled. They are well suited for abrasive or high-temperature products by inserting replaceable liners that ensure a long and productive operation life.
Electromechanical Vibratory Conveyors are available in single mass or natural frequency designs. They convey products at consistent rates between applications within industrial processes. JVI Conveyors can be configured to handle a wide range of bulk materials. This includes abrasive resistant liners and coatings, and enclosed or open troughs. They are also able to receive products from single or multiple inlet points.
Electromagnetic Vibratory Feeders
Electromagnetic Vibratory Feeders are effective in both heavy-duty and light-duty applications when precise control is required. Feed rate control from zero to 100% makes them a preferred solution for metering, batching, loss-in-weight or gain-in-weight applications. Electromagnetic drive motion works by energizing an electromagnet to pull against a secondary spring mass system at a constant frequency in order to create and amplify a linear displacement.
Electromagnetic Pan Feeders discharge hoppers and silos at precise feed rates for batching and mixing applications. Thyristor controllers deliver 0-100% feed rate adjustability, instant start / stop operation, manual operation, or remote interface via PLC analog signal.
Electromagnetic Tube Feeders are designed to discharge hoppers at precise feed rates in batching or mixing applications. Customizable to the application, these feeders are ideal for applications with small space requirements and available with top or bottom mounted drives.
Electromagnetic Dosing Feeders excel in light to fine duty applications to discharge hoppers or silos at precise feed rates. They deliver 0-100% feed rate adjustability, instant start / stop operation, manual operation or remote operation via interface with a PLC. This makes them ideal for metering, batching, or for use in loss-in-weight and gain-in-weight scaling system applications.
Application Specific Feeders
JVI offers vibratory feeders unique to specific applications. JVI Cone Crusher single mass electromechanical vibrating feeders are designed to deliver high capacities with a 360-degree peripheral feed utilizing simple yet sophisticated electronic controls. The Titan series of cascading vibratory feeders handles high head load and discharge challenges of long discharge openings on wedge shaped hoppers.
Titan Feeder is a unique multi-feeder system for discharging large-slotted hoppers in railcar and truck unloading. These heavy-duty, cascading electromechanical feeders are mounted below large slotted hoppers and deliver a controlled feed rate onto belt conveyors. Each feeder is energized thru a PLC with the JVI proprietary algorithm for optimum hopper unloading.
The Cone Crusher Feeder is a single mass electromechanical feeder designed to feed aggregates or other bulk materials into a cone crusher. These feeders are designed with center hole discharge that delivers a 360-degree homogeneous feed into the cone crusher. This enables enhanced uniform on-spec crushed product and a longer wear life.
