Results: The client sourced two Vortex Loading Spouts to interface the discharge of each bulk bag unloader with the loading port of each ball mill. Above, 1,800 lb | 815 kg bulk bags of glass frit blend are placed in the bulk bag unloaders. Then, the spouts are extended into the loading port of each ball mill before glass frit blends are discharged. Once the ball mills are filled, the spouts are retracted and each ball mill’s loading port is closed. The ball mills are used to grind the glass frit before mixing it with water to create a paste-like substance. The mixture is applied to the interior of water heaters before they are dried and furnace-fired, to create a corrosion-resistant lining.
