Derrick - Vibrating Screens – Stack Sizer

Vibrating Screens – Stack Sizer

Vibrating Screens – Stack Sizer

Applications

Vast range of applications including: Aluminium Dross; Bauxite; Chromium Ore; Coal; Colombium; Copper; Feldspar; Ferberite; Garnet; Gypsum; Iron Ore; Kaolin; Lead and Zinc; Mineral Sands; Nitrates; Phosphates; Platinum; Potash; Rare Earth Minerals; Resin Pellets; Scheelite; Silica Sand; Tantulum/Niobium; Tin Ore; Titanium; Tungsten; Ore Uranium.

The Derrick Stack Sizer vibrating screening machine has been installed in numerous applications in the Australian mining industry and there are currently in excess of 1400 Derrick Stack Sizer screening machines installed world wide.

 

Description

Depending on individual application requirements, the Stack Sizer can come as a single deck or up to five decks stacked one above the other and powered by one pair of high frequency vibrating motors creating a high frequency linear motion throughout all screen decks.

As feed is presented to each vibrating screen deck, classification takes place with the undersize passing through to individual undersize collection pans leading to a launder and single unders discharge outlet and the oversize is conveyed to the oversize launder and single overs discharge outlet.

 

Options:

• Repulp trough – for maximum separation of fines.
• Derrick Flo Divider system – for a representative feed to each Stack Sizer machine and/or individual screen decks.
• Urethane Screen Panels – high open area, high capacity, long life, anti-blinding, as fine as 45 microns.

Features & Benefits:

• The Derrick Stack Sizer Vibrating Screen has low operating and maintenance costs.
• These vibrating screens have very low dynamic load minimising structure requirements.
• All Derrick vibrating screens are of high quality construction and are built to last.
• The Derrick Stack Sizer has a small footprint but a high capacity due to the vertical stacking of the vibrating screen decks. The Stack Sizer has up to five vibrating screen decks operating in parallel for a total effective width of 5.1 m (17 ft).
• High separation efficiency
• Improved downstream processes

Closing Grinding Circuits

The comminution process continues to be the most energy intensive operation in most mineral processing facilities. Studies conducted by researchers through the years have demonstrated that the largest potential improvement in the comminution process could be achieved by improved classification.

The commercial-scale replacement of hydrocyclones with Derrick high frequency vibrating screens in closed grinding circuits has demonstrated significant metallurgical and economic benefits, including increased production rates and lower power consumption per tonne treated. Downstream unit operations such as flotation and dewatering also benefit due to a reduction in overgrinding and specific surface area, resulting in improved product grade and recovery and reduced dewatering costs.
