The need to move, convey and feed product exists in virtually all industries. Whether asophisticated food processing plant or a simple packaging line, product needs to move from one area to the next. This book, How to Choose and Use Vibratory Feeders and Conveyors will focus on selecting vibratory equipment to move raw and unfinished goods in process applications meaning, it will not discuss belt conveyors, forklift trucks, gravity flow storage systems or pick and pack modules moving finished goods. It is written to help users select the correct vibratory feeder, conveyor or screener for theirparticular...

HOW VIBRATORY EQUIPMENT WORKS The Vibratory Movement Vibrating, again by definition, means to move back and forth rapidly.Ӕ The equipment and process solutions described in this guide all use this rapid back and forthӔ motion to move or convey product. On a vibratory feeder, material is thrownӔ up and forward so that it drops to the surface at a point further down the tray. This is the feeders amplitude. The number of times per minute that this repeats is the frequency. A third variable is the angle of deflection҅ meaning how high the product is thrown as compared to its horizontal movement....

Single-Mass & Two-Mass Designs Feeders and conveyors transfer their drives natural vibration to the tray either through asingle mass or two mass system. The drive unit is contained in the ғmoving mass and creates the vibratory motion. Single-mass units are anchored in position (usually to the floor) and transfer the driveԒs vibration directly to the tray or trough through its springs. By using the factorys floor as a reaction base, a single-mass conveyor can be destructive causing damage and creating vibration in the shop floor. A Two-mass unit has the ғmoving mass connected to the ԓreaction...

Dense Rubber Springs are typically used on heavy-duty feeders and conveys to providestability and motion control between the drive and the tray. However, rubber springs are limited to use in environments below to 120 F. Steel Coil Springs are commonly used in heavy duty and high temperature applications.These coils are effective in ambient temperatures up to 300 Fiberglass Springs (or boards) are the most popular springconfiguration for light and medium duty applications. Fiber- glass springs of varying lengths, widths and thickness are mounted on the moving mass of the drive and are attached...

Product Size One of the most obvious considerations when selecting vibratory equipment is the size ofthe material to be processed. There are many factors involved in choosing the proper vibratory feeder, conveyor orscreener. The material being processed is the most important element in selecting equipment. Many standard models of feeders and conveyors can be fine tuned to improve the product flow. Selecting the proper equipment for the type of application can ensure years of trouble free service. Below are some of the key considerations. Material Considerations Coarse Material Midsize Material...

Material Bulk Density The weight or bulk density of a product effects its feeding characteristics greatly. Light (less than 10 lbs (4.53 Kg)/cubic feet) materials, especially fine (-50 mesh) do not have as much mass and feed more slowly than heavier products. High Deflection electromagnetic or mechanical feeders handle these light weight products effectively. Did you know? Eriez FeederCap > Ү software helps calculate feeder traycapacities.

B Feeders Eriez B Feeders are heavy dutyElectromagnetic Feeders designed for the glass, steel, chemical, fastener, coal, and aggregate markets where high capacity is required with the best linearity. B Feeders are virtually maintenance free. They can be provided with abrasion resistant replaceable liners and with capacities of 400-1700 cubic feet (11.32 - 48.13 cubic meters)/hour. 11 Inertial Feeders ֖ The I-36 and I-56 Inertial Feedersare special light-duty Electromagnetic Feeders designed to replace multiple side-by-side drives. This type of feeder has application in feeding small amounts of...

Feeders, Mechanical Ultra Force Feeders The Ultra Force Mechanical Feeder is a two-mass coil springdesign using a motor driven eccentric shaft. It uses standard off-the-shelf motors and bearings and will feed capacities of 2,000-25,000 cubic feet (56.63 to 707.92 cubic meters)/hour of aggregates, glass, steel, and coal. HV Feeders ֖ is a unique low profile two-mass rubber spring design using standard off-the-shelf components. It is ideal for use in tunnels or in areas where headroom is a problem. HV Feeders have capacities of 2,000-40,000 cubic feet (56.63 to 1132.67 cubic meters)/hour of aggregates,...

SM Conveyors - Single mass units are Eriez' least expensive mechanical conveyors,because they use the floor or base as their reaction mass. This allows for a low profile and efficient system to convey materials and parts. These efficient single mass conveyors move light loads of bulk materials at flow rates up to 18 tph (16mtph). TM Conveyors are two-mass Mechanical Conveyors designed for medium dutyapplications such as food and pharmaceutical. They use an off-the-shelf motors, standard bearings and fiberglass springs. HV Conveyors ֖ is a heavy duty two-mass Mechanical Conveyor designed for coal,...
