Rotary Dryer Machine for Lime Production Line
Rotary Dryer/Drier
The Rotary dryer is mainly used in building materials, metallurgy, chemical plant, cement plant for drying of limestone slag, coal powder, slag, clay stone and so on. This dryer is formed by rotary body, lifting blade, driving device, supporting device and sealing ring. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.
The usage of rotary dryer:
Rotary dryert is widely used for drying materials in the industries of cemet, mine, contruction, chemical, food, compoud fertilizer, etc. Feeding and discharging unit is installed with thermocouple to control drier temperature. The temperature change of dryer's feeding end can be indicated by the thermometer to control the inner drier temperature ( generally 250-350° C)
The structure of rotary dryer:
Rotary dryer machine is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.
The working structure of Rotary dryer:
Rotary dryer adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immindiately by spiral board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.
Our rotary dryer's advantages are as follows:
The process of dryer is very advanced, which takes fast drying with high temperature, high heat transfer coefficient, high heat efficiency and large drying capacity. Air flow drying combines with the high speed agitation drying, which disperses the viscid material sufficiently and improves the contact area of material and thermal medium, thereby improves the process of drying It takes special scrapings device into the dryer so that avoid the material from sticking the wall. Wide application, easy operation, light maintainence work and stable quality.
Application:
ZK Rotary Dryer is widely used in the field of building materials metallurgies, chemical industry, cement and so on. It can dry slag, coal powder, mining powder, clay, sand, limestone and so on. It is made into rotary body, lifting blade, driving device, supporting device etc. The dryer has advantages of reason able structure, high efficiency, low energy consumption and convenient for transportation.
We supply the following dryer, wet material rotary dryer, sand dryer, sawdust dryer, coal slime dryer, bentonite dryer, ore concentrate dryer, gypsum dryer.
