1. Drum drying: in drum drying, the heated surface is the envelope of a rotating horizontal metal cylinder. The cylinder is heated by steam condensing inside, at a pressure in the range of 200 to 500 kPa bringing the temperature of the cylinder wall to 120–155°C.
Get PriceHistorically, the first type is the dry powder process. In this process, a dry powder is deposited from a roller drum. The powder is fed into the interior of a drum and, as the drum rotates and traverses a substrate, the powder is then dispensed out of the drum through a screen (Sachs et al. 1998b). The drum also acts as the compacting device.
Get PriceDense medium bath or drum can handle large sized raw coal up to 300 mm in diameter, although the feed top size is reduced to 150 mm. The bottom size is usually 6 mm. Wemco drum separator with sizes up to 4.3 m diameter up to 6 m long has a maximum capacity of 450 tph. It consists of lifters fixed to the inside of the rotating drum to reject refuse.
Get PriceDrying processes are commonly used for food and agriculture’s industry to maintain a rising variety of foods.
