Vibratory 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 dedusting process.

Separating large pieces on scalping screens.
Washing or wet screening or even de-liquefying on a de-watering screen.
Cleaning castings on foundry shake-outs or degrading sand lumps into grain size on shaker lump breakers or attrition mills.

​

Our robust products have been designed to operate at high specific feed rates and maximized acceleration with low transmitted vibration. Thus, ensuring minimum degradation and low maintenance requirements; which transmits to continuous production efficiency.

​

VPC-Systems team of engineers have over 35 years of experience in designing and building Vibratory Screens  which perfectly match our client's operational requirements and facility dimensions. All of our vibration equipment is manufactured to meet the highest industry standards, is custom-built for a broad variety of applications .

 

Technical Details:

Unique design and engineering functions can be added to all Vibratory Screens to suit operational requirements, including:

Fabrication in mild steel or ST/ST.
Fully-Encased structure and Multi-Deck Versions.
Top or bottom drive concepts.
May be fitted with a variety of screen sizes, piano wire pre-tensioned panels for damp material, perforated plates / woven wire mesh or wedge wire panels.

Widths up to 1500mm (5ft)
Lengths up to 7000mm (23ft)
Can be inclined or declined

 

Equipment Applications and Manufacturing Details:

Construction materials for Vibratory Screens includes mild steel, 304 or 316 stainless steel.

Mild steel troughs can be painted in process specific painting systems. Stainless steel troughs can be finished as per requirements.

Operation angles are critical to screen performance. A decline reduces effective screening area but will increase the processing ability of oversize content. Horizontal screens provide precise sizing but may compromise capacities. Inclined screens, like with declined, have reduced screening area but are very thorough.

​

Customised Screening Mediums:

Screening mediums have a huge effect on the way material behaves on a deck. The cheapest and most common options are steel woven wires and perforated plates. Woven wires can also be supplied as ripple or piano string style decks. Steel anti-blinding wedge wires can offer benefits in processing certain materials. Polyurethane tensioned mats or panels are popular alternatives when material is sticky or wet. Rubber screens can also be installed for better performance in certain wet materials.

Different liner materials can be installed on the screen troughs to assist in wear or build up problems. Replaceable hard wearing steels are commonly used to protect trough surfaces. Polyurethane or rubbers are used to minimise deposits of sticky materials.

Even distribution of material across a screen deck maximises the screening area available. To ensure this, vibratory screens and chromite separators are usually fed by different types of feeders or specially designed feed boxes. Screens can also be designed to take head loads (like a feeder), eliminating the transition between two separate units.
