Vibratory Screens

We can design screens to work with any plant layout, whether existing or new. Vibroflow will help with correct sizing and screen application.

We are happy to discuss any application requirements for vibratory screens.

Vibrating screens are used to separate material of varying sizes. Common uses include:

  • Sizing of particles on single or multiple deck systems.
  • Removing fine powders in the de-dusting process.
  • Separating large pieces on scalping screens.
  • Washing or wet screening or even de-liquefying on a de-watering screen.
  • Cleaning castings on foundry shakeouts or degrading sand lumps into grain size on shaker lump breakers or attrition mills.

Vibroflow offers a wide selection of designs of screens to facilitate specific requirements. We can assist in the selection of the appropriate screening technology to satisfy clients’ requirements.

When the distribution of material across a screen deck is important then screens are usually fed by different types of feeders or specially designed feed boxes. Screens designed by Vibroflow can combine a feeder and a screen into one unit eliminating the transition between units.

Types of Vibratory Screens

A Vibratory Screen can come in many different shapes and sizes. Below are a few of the more common types:

Drive Types

Vibroflow supplies two types of vibratory drives, sub resonated tuned and direct drive. The main advantages of the sub resonated drive are the prolonged life, minimal power consumption and low dynamics. Sub resonant drive involves mounting the motor directly to a counter-mass. The output of the motor is then tuned to the natural frequency of the screen’s drive system. This drive system is idea for large screens typically found in the mining industry.

Direct drive involves locating two motors directly onto the trough of the vibrating screen. Vibration is then directly applied through the trough to the material.

Direct drive is a usual choice for smaller pilot screens. The benefits of this drive are ease of use and low cost. It consists of placing two motors directly onto the trough of the vibrating screen.

More information can be found on the Sub Resonant Information Sheet.

Build Specifications

We can supply vibratory equipment built to spec to ensure we meet any stipulations. We understand the complexities involved and can meet the required regulations. By using stainless steel in the build we can meet the hygiene regulations and not affect magnetic equipment. Long life can be achieved by using wear resistant steels, polyurethanes, stainless or bisalloy liners for troughs.

Liners

Liners are used to prolong equipment life. A replaceable liner will be much cheaper to replace than the entire trough of a vibratory feeder. The best liner for the application will be based on the required wear resistance, friction coefficient and access for maintenance. Typical liner materials include steel, stainless, bisalloy and polyurethane.
