rotary drum dryer is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover and so on. Rotary drier manufactured by victor machinery adopts new lifting plate, which is of functions like guiding, current-sharing, and material raising.the rotary drum dryer works with disc granulator in a complete whole organic fertilizer production line to produce bio organic fertilizer granules.the materials are raised and evenly drop so that they are in full contact with heat for better drying efficiency. Our rotary drier is designed with the best working conditions, which enables it to save 10-15% of energy and increase 10-15% of productivity compared with common dryers.
rotary drum dryer is widely used for drying materials in industries like cement, mine, building materials, chemistry, food and fertilizer, etc. This rotary drying machine comes with thermocouples on the feeding and discharging device to control the temperature. Thermometers are also adopted so as to better control the working temperature (generally 350-380°) of the rotary drier.
Brief introduction on working principle:
First step: connect the natural gas to the burner to have the hot heat,
Send the raw material by screw conveyor into the drum, there has fan it will
Absorb the heat into drum, the drum rotary with the heat and the materials for drying, after the moisture has out disposed ,the fan again send the dry materials into the dust collection machine(Shaq Dragon) for discharge. The drum dryer has continues drying function, and the dry effect is higher than other dryers.
Rotary dryer can reduce coal moisture from 40-50% to less than 5%, fuel can be coal, natural gas, oil. rotary dryer consist of shell, front and rear supporting wheels, feeding and discharge device, gear device and gear cap. Because of
the adoption of reasonable working parameters, rotary dryer, which used with rotary drum granulator to make up of a complete whole compound fertilizer production line,can save 10-15% energy and increase production by 10-15%,which is manufactured by victor machinery.the Rotary dryer’s heat source is a combustion apparatus.the rotary dryer adopts direct flow heating with heat source from firing unit. The material to be dried is pushed back immediately by spiral board after going in the shell from feeding tank or feeding chute. Because the drier is installed in an inclined position, material flows to the back end under gravity and rotation force. At the same time,the rotary dryer is lifted by board repeatedly and thrown down accordingly, which makes the material form an even curtain, so that the rotary dryer can exchange heat sufficiently with the heat flow.
features of rotary dryer
1.The final moisture of raw materail can be 1%-15% what is adjustable.
2.The special internal structure of wood chip rotary dryer ensure the wet materials that will not block and stick the dryer.
3.fertilizer rotary dryer can resist the high temperature so that it can dry the material quickly and have a large capacity.
4.fertilizer rotary dryer can use coal,oil,gas,biomass as fuel.
5.We can provide you the new way to use few fuel so that you will get low drying cost.
6.We can provide the dedusting equipment to ensure the wood chip rotary dryer won’t harm our environment.
7.fertilizer rotary dryer is easy to operate and maintain.
