How to Design and Size a Vibratory Feeder Conveyor Based on Application Requirements

Similar to vibratory tables in their many uses and applications, vibratory feeders are also great problem solvers.  Well known for their ability to effective move material from point A to point B, a well-designed vibratory feeder offers flexibility to the end user to get the task done.

Feeders can range from small base mounted CF-A, pneumatic powered feeders moving small quantities dry bulk material in a controlled manner to much larger base or cable supported EMF, Electro mechanical feeder, conveying literally tons of material an hour. Off the top of my head a short list of materials that Cleveland Vibrator’s vibratory feeders have worked with would include: almonds, crushed limestone, shelled corn, powdered metal, metal billets, various pipe fittings, scrap brass and bronze, crushed and shredded automobiles, hot dross and much more.

Typically, a feeder application will require the movement of some given amount of material with a known bulk density over a desired distance. Read More…

Air Powered Vibratory Feeders: 3 Things To Know Before Making a Buying Decision

When it comes to handling dry or semi dry bulk material, there are few means to transport the material from point A to point B. The common options are pneumatic conveying equipment, frequently dense or dilute phase, belt conveyors, screw augers or vibratory feeders, flat pan style or enclosed tube style. There certainly is a time and place for each of these options but we will focus on the vibratory feeder design.

Companies looking to make a buying decision on which type of equipment to install that will handle the material typically turn to the vibratory feeders that are powered by a pneumatic or air piston vibrator for one of or a combination of a few reasons:

The air powered vibratory feeders can be the low cost alternative to the electromechanical or electromagnetic powered vibratory feeders. The biggest cost savings can come directly from the vibratory drive or mechanism and the vibratory controls. Electromechanical feeders typically have two vibratory motors while the electromagnetic feeders typically have one large vibratory drive attached. Each of these electric powered options require an electrical control box, with dual thermal overload protection for the electromechanical vibratory motors, for on/off operation, speed control or intensity of the vibration control. In contrast, the air powered feeders are driven by a single non-impacting piston, for example the Cleveland Vibrator VMSAC design, units and either controlled by a manual ball valve or 2-way, normally closed, solenoid valve.

Vibratory Feeders & Screeners: The Affects of Force, Acceleration and Frequency

We often receive calls from customers that need to make adjustments to the product flow in their vibratory feeders or screener/feeders.  Our challenge is to determine what style equipment is being operated to provide the appropriate options.  The following are three basic drive options which produce linear force that can be used to power vibratory feeders or screener/feeders.  To clarify, a screener/feeder is designed to feed the material with that same vibratory action also serving to help stratify the material – Read More…

How To Select The Proper Vibrating Feeder Design

Jack Steinbuch
test

There are two basic designs available when selecting a vibrating (linear) feeder: electromagnetic and electromechanical.  Air powered vibrating feeders are basically an alternate to the electromechanical feeders as they have the same simple brute force design concept – the vibratory drive is directly attached to the tray. Our challenge is to obtain as much information about the application to make recommendations Read More…
