Vibratory Feeders & Vibratory Feeder Manufacturers

Vibratory feeders convey parts or bulk material through various stages of finishing, packaging and recycling by means of vibration. Unlike pneumatic conveying, screw conveying and standard belt conveying, vibratory conveying offers solutions for moving delicate or sticky food materials without causing liquefying or damage due to shearing or rough handling.

Vibratory feeding, also known as vibratory conveying, offers low-maintenance parts and material handling, as vibratory conveyors and bowls use no moving parts except the vibrating drive installed beneath the bowl or feeder pan, away from contaminating materials. There are two main types of vibrating feeders: vibratory bowl feeders and vibratory conveyors. Vibratory bowl feeders, also known as vibratory bowls or centrifugal feeders, are a type of parts feeder used in parts manufacturing to align finished or semifinished parts for final processing or packaging. Vibratory conveyors encompass a wider range of troughs, vibrating screens and trommel screens which convey and/or sort bulk materials during processing. Rotary feeders, also known as rotary airlocks or rotary valves, occupy a third category by providing air-tight bulk material feeding into screw conveyors or vibratory conveyors. Linear feeders, also referred to as inline feeders, are typically used to convey parts in a consistent flow from bowl feeders over short to relatively long distances in a vibratory linear motion.

Vibratory bowl feeders are used extensively by small parts manufacturers as an extremely efficient means of orienting products for further finishing or for distribution. Originally designed by pharmaceutical companies to count, sort and organize pills, bowl feeders also orient fasteners, ammunition, o-rings, molded rubber parts, toothpaste caps and many other small parts for packaging or finishing. Vibratory conveyors, screens and trommels are used for powder and bulk material handling in a range of industries, including pharmaceutical, agricultural and food processing. Recycling industries use vibratory conveyors extensively to convey and sort materials such as plastic, wood, crushed cement and metals for reclamation, while fertilizer, sand and gravel, mining and pulp industries use trommel screens and vibrating screens to convey, sift and sort. A particularly powerful type of vibrating screen is a grizzly screen, which is most often used in the mining industry. Rotary airlock feeders often accompany vibratory conveyor systems, particularly when conveying powder bulk solids. Rotary feeders are often used in conjunction with dust collecting systems to convey collected waste dust into disposal areas or reclamation processing. Electromagnetic vibratory feeders are one of the two main types of vibratory feeders in terms of how they are powered, the other being electromechanical vibratory feeders which are typically driven by a motor supported by either an eccentric crank or eccentric weights.

Similar to vibratory finishing bowls, bowl feeders are metal, silicone or plastic bowls equipped with a vibrating drive beneath the bowl, where the bowl is mounted to the base. A ramped ridge runs up along the edge of the bowl in a spiral, leading to the outfeed area. Bowl feeders vibrate in a circular motion, driving parts up the ridge, which is usually designed for a specific part; it narrows as it reaches the outfeed, forcing parts to form a single-file uniform line. Washers, o-rings, legos, coins and an unlimited number other small parts are quickly and flawlessly aligned for counting and packaging by being dumped into the center of the bowl feeder. Vibratory conveyors are metal troughs which vibrate in one direction, conveying powder bulk solids or heterogenous mixtures from one process to another. Some vibratory conveyors have ultra-low vibrations designed specifically for solids which are delicate, sticky or may liquefy, such as gummy bears or lettuce. Trommels, or trommel screens are vibrating screens which help sort small particles from large particles. Rotary trommels, a large tumbler design, aid in gravel processing and recycling; trommel magnets are often used in conjunction with metal recycling rotary trommels to help sort ferrous materials from non-ferrous materials. Continuous flatbed trommels may have screens or filtering devices which sort particles of different sizes as large particles are conveyed to containment or further processing.

There are many advantages to incorporating vibratory feeders into various industry processes. For instance, parts feeders provide a cost-effective alternative to manual labor, saving manufacturers valuable time and labor costs. One operator can oversee a number of automated machines, as opposed to one worker hand loading one machine. Bowl feeders align, count and sort small parts far more quickly, effectively and accurately than could be done by hand; this also provides an ergonomic solution to monotonous and physically strenuous sorting tasks. Vibratory conveyors present alternatives for powder bulk solids and heterogeneous mixtures which are too delicate, or difficult to convey by pneumatic conveying, screw conveying or belt conveying. Friable or sticky powder bulk solids which would normally cake or agglomerate during screw or pneumatic conveying flow evenly on vibratory conveyors. Trommel screens and rotary trommels cut down on the huge amount of labor required to sort recyclable materials, an important step in making recycling a cost-effective part of manufacturing processes.
