Read OnThe main impurities in the manganese ore and mill scale are CaO, MgO, Al 2 O 3, and SiO 2. Before roasting, all the raw materials were crushed, ground, and screened to 100 wt% by being passed through a 0.074-mm mesh in advance. The average particle sizes of the mill scale and manganese ore powders are 29.4 μm and 24.2 μm, respectively.
Read OnIn the hot-rolling process, owing to oxidation reactions, mill scale is formed on the surfaces of semi-steel products in reheat furnaces and on rolling trains and stands [1,2,3].The mill scale is washed away from steel surfaces and flushed into flumes underneath the hot-rolling lines by a large amount of contact water, which includes descaling water and cooling water.

Read On3.2 Bench-scale tests Bench scale flotation tests with pyrite cinder were systemically conducted. Firstly, the roughing-circuit aiming to find the appropriate size of grinding product and dosage of reagents were tested. The flotation separation flowchart is shown in Fig.4, and the results of separation are shown in Fig.5.
Read OnDrag Tank for Mill Scale Separation. A new steel tube mill required a scale separator to capture and remove solids from mill water. The unit required a drag conveyor for scale collection and also needed the capability to remove floating oil. Monroe was selected due to our experience with heavy-duty conveyors, robust tank designs, and custom ...
