The volume flow rates and mass flow rates, when plotted individually for metal and slag against time duration as shown in Figures 5(a) and 5(b), reveal that there is a steep increase in volume flow rate for slag but equal steep decrease in slag mass flow rate after slag-out time (= 64 min after tap open). This phenomenon can be attributed to ...

He also noted that these equipment can handle a variety of bulk solids ranging from crushed/lumpy materials to solid with feed rates upto 2500 tons per hour with high operational accuracy. It was observed that the appellant's equipment were supposed to be of accuracy of …

Another volumetric feeder uses vibration rather than a rotating screw to deliver a constant volume per unit time. Vibratory tray feeders shake the delivery tray at a constant frequency. To change the feed rate, the vibration amplitude is changed. In some feeders, the hopper vibrates at the same frequency as the discharge tray does.

Conveyor loadings may sometime exceed the recom­mended % of Loading, listed in the materials table. Considerations as to the material characteristics may justify up to 95% loading of tubular or shrouded con­veyors. The following table lists maximum speeds limited with regard to the percentage of loading nor­mally recommended for the specific ...

But due to the backward air flow rate and the loose air volume, there is no single flow monitoring device, It is difficult for the operator to adjust the air volume balance between the two back feeders and the same feeder, the return air chamber and the loose air chamber through the adjustment of the volume of the two air chambers.
