Spodumene Dense Phase Conveying

Filquip has done a number of Dense Phase Conveying Trials for Spodumene Ore (An ore of lithium).

When the product was first received it was quite wet in the sample bucket and this did not load or convey well, getting stuck. Once laid out in drying pans and dried out in the sun for 4 hours (5.3% loss of product weight or 5.3% of the original product weight was moisture driven off) then it conveyed very well through the dense phase conveyor.

The video shows how much the wet Spodumene binds to itself in the video of loading and conveying and then how easily it flows once dried out (but more dusty to handle once dried).

Fly Ash Dense Phase Conveyor

Filquip was engaged to specify, supply and commission a Fly Ash Dense Phase Conveyor to transport 9TPH of product a distance of 40m from a Bulk Storage Silo to a Day Bin over the production line.

The system was designed to replace the older Lean Phase Conveying system which was experiencing significant wear and maintenance requirements resulting in shutdowns of the plant. The new Dense Phase Conveyor is designed for abrasive products and only has one simple moving part in the build for minimal maintenance.

The following equipment package was supplied by Filquip:

  • BARTOne 300 Dense Phase System 300L Vessel Capacity, Throughput capacity of 9,000kg/hr of Fly Ash at 40m distance.
  • Inclusive of Electrical Control and Air Control Panels and Pipeline Air Boosters for the Dense Phase System.
  • Extrac BA.1.1.1500 Bin Activator 1500mm diameter in Painted Mild Steel Build.
  • Drop Through Rotary Valve (Model RV10.20, CS, 1.1kW Motor).

Cement Loading Bellows for Isotainers

Filquip has completed the Design, Supply and Commissioning for a set of 4 Loading Bellows for existing cement silos on a mine site. The silos are used for bulk cement storage and they fill into individual isotainers which transport the cement to the underground section of the mine.

The new loading bellows provide a safe way for truck drivers to load the cement into the isotainers as the previous method was a hand operated valve and rubber sock. Drivers can now position their truck with Isotainer on the back under the bellows and use the remote pendant controller to lower the bellows outlet onto the inlet of the isotainer.

The integrated dust extractor ensures there is no dust released during the filling process.

The pneumatic actuated slide gate valve allows the operator to open the flow of product as they wish and shut if off as required along with the integrated level sensing in the loading bellows also automatically shutting off the valve and product flow when the Isotainer is full preventing overfilling and backing up into the chute.

The following specifications were included for the Loading Bellows:

  • Qty 4: BellowJet ZAMBA.25 Models with integrated Dust control extractor in the Unit
  • 0.55kW Winch Motor and 24v Reverse Pulse Automated Air Filter Cleaning System.
  • Integrated Level Indicators for Control Feedback to the Actuated Slide Gate Valve.
  • Inner and Outer Bellows system with wear resistant inner cones.
  • With anti-spillage closure cone that retracts to close the outlet after filling is completed
  • Stroke of 2260mm (4170mm extended length, 1910mm retracted length). 300mm diameter bellow.
  • 250 m3/hr Throughput Capacity.
