Product Details

1.8*16m Rotary Drum Dryer Machine For Cement Plant
 
 
Rotary Drum Dryer Machine is also known as drum drying equipment or tumble dryer is the most common and widely a dryer equipment mining equipment.
 
Rotary dryer application Fields : Suitable for dry metal and non-metallic mineral magnetic, heavy, slime floating concentrate clay and cement industry and the coal industry
 
Rotary dryer working principle:
The wet material is added from the feeder to drum body. Cylinder has a certain inclination and rotates continuously, which makes the material under the action of gravity move from high to low. Materials and high-temperature flue gas as a drying medium enter into the dryer cylinder body under the action of the suction of the exhaust device . Material in the process of gradually moving exchanges heat with high-temperature flue gas in the way of convection, radiation, conduction. The material is heated, the water evaporation to dryness medium, and the water contained in the material  is taken away, which is the mass transfer process.
 
After drying, the material is discharged from the low-end, the material residence time in the dryer about 20 to 40 min. Exhaust gas also flows from low pressure site to high pressure site. Material is unloaded from the dryer after drying and the exhaust gas is discharged to the atmosphere by the dust collector.

 

 
Features of rotary drum dryer :
 
Point 1-Steel Plate Selection

Chemical analysis was carried out on the material inspection, according to the requirements of GB700-2006, dryer drum thickness < = 20 mm we use Q235 - A, > 20 mm we use Q235 - B; According to the GB/T 2970-2004 class ii, the range of 60 mm weld edge every board before cutting for ultrasonic flaw detection.

 

Point 2-Dryer Drum Welding

the dryer cylinder section for toroidal welding, longitudinal along the entire circumference of not more than two weld article number, and shell welds shall be full, the minimum is not lower than the parent metal surface, the top should not be higher than 3 mm, feed plate weld should be smooth.Weld edge bite depth should not be greater than 0.5 mm, continuous length should not be greater than 100 mm, should not exceed the total length of each weld bite edge which 10% of the weld length

Point 3-nspection

Examination all the parts according to the drawing after processing completion. Spraying primer, rust preventing paint, and heat resistance paint.
