Reduce the Noise Level on Your Vibratory Equipment

By Jack Steinbuch

OSHA specifies that a hearing conservation program should be in place when “noise exposure is at or above 85 decibels averaged over 8 working hours, or an 8-hour time-weighted average (TWA)”. This can be an issue for some vibratory equipment. However, we have selections available that will reduce noise levels which can result in many positives for your facility (OSHA).

For example, did you know investing in noise-reducing vibration can lead to an increase in productivity and overall safety? High noise levels can lead to short- and long-term physical damage including ringing ears, temporary changes in hearing, and long-term hearing damage or loss. But, less commonly known, it can also put a strain on your pocket by reducing productivity, contributing to poor communication and concentration, and can even contribute to workplace accidents by limiting your employee’s ability to understand speech (OSHA).

Since there is a wide variety of vibratory equipment, for this blog, we will focus on “brute force” vibratory equipment.  The vibrating body is directly installed on the equipment and is driven by a vibrator or dual motors, and the supporting structure is isolated from the vibrating body. Now let us look at potential ways to reduce their noise level:

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

Along with our other vibratory equipment, vibratory feeders are great problem solvers. Feeders are well-known for their ability to move material from point A to point B effectively. However, a well-designed vibratory feeder offers flexibility to the end-user and increased safety and efficiency in the process.

Feeders can range from small base mounted CF-A, pneumatic powered feeders moving small quantities of dry bulk material in a controlled manner to a much larger base, as well as a cable-supported EMF, electromechanical feeder conveying literally tons of material an hour. This breadth of design capabilities allows our vibratory feeders to move material effectively in various industries for many different applications.

For example, we have incorporated vibratory feeders into the processes of these materials and more:

  • Almonds
  • Crushed Limestone
  • Shelled Corn
  • Powdered Metal
  • Metal Billets
  • Various Pipe Fittings
  • Scrap Brass and Bronze
  • Crushed and Shredded Automobiles
  • Hot Dross

We work with a variety of industries feeding an endless variety of materials!

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

By Mike Stratis

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, these reasons:

Air Powered Feeders Work Well Within a Budget – First, and maybe most importantly, the purchase price. 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 requires an electrical control box, with dual Pneumatic Vibrator, Industrial Vibration, Cleveland Vibrator Companythermal 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 units are either controlled by a manual ball valve or 2-way, normally closed, solenoid valve.

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

By Jack Steinbuch

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

By Jack Steinbuch

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…
