Homogenisation in Blast Furnace Industry
The tank is aimed to collect waste water from wet cleaning of blast furnace powders, at a maximum working temperature of 50°C, with a solid concentration up to 15% of the total volume. The maximum specific gravity is 1.2 kg/l. The dimension of the tank is 11 x 9 x 4.5 m (W x L x H),maximum liquid level 4.2 m. The flow rate is 20000 m3/h.
The mixer has a heavy-duty task (24/7/365), since the basin shall work as a storage to supply with a continuous cycle the sludge dewatering plant.
PRO-DO-MIX’s proposal is a single mixer, model GEL.A8290.L.425/PCX, with an industrial planetary gearbox with AGMA service factor >4. All wetted parts are completely anti-abrasive rubber lined, 4 mm thickness, to resist the high abrasiveness of the powders and to reduce maintenance operations throughout the mixer life.
The pictures show the carbon steel impeller, 2900 mm diameter, completely welded to the shaft, before the rubber lining operations.
A special seaworthy wooden box has been manufactured to fit the lined shaft and impeller during the shipping.
