Drum drier is a drying device, widely used in mining equipment. It can be divided into two categories, Direct and indirect heat transfer drum dryers. The main internal structure In order to increase the material evenly distributed in the rotor parts of the cross section in good Contact with the drying medium, in the cylinder body installation raise plates. There are several types of raise plate. 1). Lifting type: For large or easy to bond the material in the tube wall. 2). Cross-shaped or frame-shaped: Applicable to brittle and easy dispersion small pieces of material, make the material can be evenly dispersed in cylinder whole section. 4). Sleeve type: For double entry Heat transfer for the double (or half the diameter heating) rotary drum dryer raise plate. 5). Separate format(fan): For very fine particles and the material prone to flying powder. Materials accumulate on grid Board when it into, then cylinderrotates, the material is turning and continue contacts with the hot gases, at the same time, the decrease of height landing, reducing the dry materialbeing gas away possibility.type(mm) indiclination(%) rotation speed(r/min) input tempreture(º C) motor power(kw) outpur(t/h) weight(t) 600× 6000 3-5 3-8 700 3 0.5-1.5 2.9 800× 8000 3-5 3-8 700 4 0.8-2.0 3.5 800× 10000 3-5 3-8 700 4 0.8-2.5 4.5 1000× 10000 3-5 3-8 700 5.5 1.0-3.5 5.6 1200× 10000 3-5 3-8 700 7.5 1.8-5 14.5 1200× 12000 3-5 3-8 700 11 2-6 14.8 1500× 12000 3-5 2-6 800 15 3.5-9 17.8 1800× 12000 3-5 2-6 800 18 5-12 25 2200× 12000 3-5 1.5-6 800 18.5 6-15 33
