Vibratory Screens

recycling screens

There are four different categories of screening equipment available.

Click a link below to jump to a product description.

  1. Finger Screen – non-blinding screens, cascading separation of materials
  2. Direct Drive Vibratory Screens – very cost effective, few moving parts, heavy-duty
  3. Vibrating Grizzly Screens & Feeders – screen and feed large aggregate material with low energy requirements
  4. Natural Frequency / Two-Mass Vibratory Screensenergy efficient, higher consistency and speed

These heavy-duty vibratory screens are designed to handle a wide diversity of screening and classification tasks. Manufacturer has extensive experience working with a variety of screen technologies (including vibratory, fluidized, pneumatic, and mechanical fingers). The end result is a customized screening solution for your specific needs – one that improves process throughput while minimizes the amount of energy that’s consumed through the process.

Exhaustive testing procedures help the manufacturer to develop high quality separation machines that can tackle even the most demanding and unexpected challenges.


1. Finger Screens

Finger Screens non binding

Finger Screens

This non-blinding design uses staggered, interlocking fingers to sift through materials quickly and consistently. The design allows for a series of screens through which materials can cascade, resulting in several stages of classification. The design reduces trapping and jams, while its staggered fingers prevent unexpected material bypass. Finger Screens avoid many of the common issues experienced with traditional wire mesh screens.

As the unit is designed with open below decks, material freely falls from level to level. This makes cascading material flow possible, moving materials through different sizes of tapered finger to establish multiple classification groups. Vibratory motion evenly spreads material across each screening level and breaks up material clustering, maximizing process efficiency.

Important highlights include:

  • Manufacturer’s uniquely developed cam-out surface reduces catching, binding and trapping.
  • Units can be custom-engineered to your classification needs and ideal load capacity.
  • Modular decks allow for easy replacement and reconfiguration.

2. Direct Drive Vibratory Screens

Direct Drive Vibrating Screens

Direct Drive Vibratory Screens

In addition to two-mass vibratory screens, manufacturer also offers direct drive (brute force) vibratory screen designs. These screens come with super heavy-duty bodies, and are built to handle even the heaviest and most abrasive materials. These units are very cost-effective. They require few moving parts, resulting in a reduction in maintenance costs.

Important highlights include:

  • Options for rubber deck screens, perforated screens, or finger screens.
  • Standard sizes and custom-engineered designs are both available as either two-mass drive or direct drive systems.

3. Vibrating Grizzly Screens & Feeders

Grizzly Feeder

Grizzly Screens & Feeders are one of the manufacturer’s most heavy-duty options for vibratory screens. These units screen and feed aggregate materials without demanding large energy consumption, making them as efficient as they are durable. These grizzly screens have been stress-tested in an extensive set of mining, ore, and mineral-processing contexts.

Important highlights include:

  • Options for multiple sizing decks on each unit, explosion-proof motors, speciality finishes & materials, and VF (Variable Frequency) drives.
  • Standard sizes and custom-engineered designs are both available.
  • Sub-resonant natural frequency design will automatically adjust itself to weight and head load changes, in order to sustain a consistent feed rate.

4. Natural Frequency / Two-Mass Vibratory Screens

Two Mass Vibratory Screens

Two Mass Vibratory Screens

Compared to traditional direct drive designs, which rely on brute force to screen materials, Two-Mass Vibratory Screens are both more energy efficient and capable of screening at a higher consistency and speed. Two-mass designs have been proven to require five times less energy than generic direct drive screens. While a brute force/direct drive screen would require over 150 horsepower to operate, a two-mass screen that relies on background vibration can operate on an engine with 30 horsepower.

Units are load responsive, demonstrating better screening efficiency as tonnage is increased. Stroke level is maintained with the introduction of higher-volume materials, unlike brute force screens (which will lose stroke as weight is added).

Important highlights include:

  • Options for replaceable decks, units with multiple decks, corrosion resistant finishes, and banana-style decks.
  • Operational upon delivery, with no special setup requirements.
  • Compact, low-horsepower vibratory motor is accessible and easy to replace.
