Indirect heat transfer dryer gypsum calcination rotary dryer
Rotary dryer Usage and application :
Gypsum Drum dryer is mainly used for drying materials with some moisture and granularity in ore beneficiation, building material, metallurgy and chemical department. Drum dryer has high adaptability to the materials so that it can be used for drying all kinds of materials, and in addition, the operation of this equipment is simple and reliable, for this reason, it gets wide application.
The Structure for the Rotary Dryer
Rotary dryer consists of the main drum, feeding part, discharging part, big gear, pinion gear, riding rollers, small rollers, reduer, motor etc. The outer motor drives the big gear and then the dryer works.The heating method includes downstream, upstream.
rotary dryer Working principle:
The rotary dryer system is mainly composed of a heat supply source, a loading machine, a feeding machine, a rotary drum dryer, a material crushing device, a discharging machine, an induced draft fan, a discharger, and a power distribution cabinet.
The lifting plates which are arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. Then water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Then the materials would be dryed.
Rotary Dryer Features:
1. Shell adopts assembled structure, and its precision has been improved a lot, which will be convenient for transport.
2. According to different fuel properties, suuitable lifters will be used. This can make material receive more heat exchange.
3. Sealing is simple but efficient, which can improve capacity and improve whole machine performance.
4. Its matching combustion furnance is energy-saving type, which takes small area and is easy to adjust.
