NSI Equipments Private Limited
Paddle / Rotary Drier
Product Description
Rotary Dryers:
Rotary Dryers are used to remove moisture from material using hot gases to heat the feed material and to evaporate the water. Rotary Dryers are suitable for drying wide range of materials continuously because of its ability to process material having considerable variation in size and composition.
Construction :
Rotary Dryers are slightly inclined cylinder shell supported by two nos. riding rings(tyres) running on a set of support Rollers. Fabricated in carbon, stainless steel and carbon+Ebonite lined with flights or lifters are welded or bolted internally to produce cascade of particles falling through hot gas stream. The mechanical lifting of the material allows to dry materials from filter cake to coarse minerals also helps in breaking-up lumps for uniform drying. The length of the drum may range from 4 to 10 times its diameter. Normal dryers the length will be 10 times its diameter and usually operate with 12 to 15% of their volume filled with the material.
End closer seals :
End closer seals :
Both the ends of the drum are closed by steel fabricated hoods with air inlet/outlet chute with suitable seals in between the hood and the dryer drum. If slight ingress of air is acceptable simple felt seals can be used, bolted to a stationary end plate and positioned in between to seal rings. If air is unacceptable spring loaded friction seals are provided, where two finished metal surfaces are in contact under spring pressure. The sealing segments require regular adjustment and replacement.
Operation :
Operation :
Dying is achieved by passing the material being processed through the horizontal rotating drum which also passes a current of hot air. Lifters or flights fitted internal surface of the drum lift and cascade the material through the hot air stream. The hot air steam can be directed through the cylinder either in the same direction as material (co-current) or in the opposite direction (counter current). Counter current applications are more efficient in terms of energy input but give rise to high product temperature, with the associated handling problem.
Air Heater :
Air Heater :
The air may be heated indirectly by means of thermal oil or electricity-heated or steam heat exchanger.
Air Handling System :
Air Handling System :
In Rotary Dryer the flow of air is induced by a centrifugal fan located up stream of the air heater with filter at fan inlet. The exhaust air is removed either by a second centrifugal fan at the outlet or direct at outlet end of the dryer and through dust collector.
The exhaust gas stream from any drying operation inevitable include a significant amount of fine particles and these fine particles may be collected by passing the gases through cyclones or bag filter or wet scrubber or any combination on any or all of these, depending upon the nature and quantity of dust involved.
Process Control :
The exhaust gas stream from any drying operation inevitable include a significant amount of fine particles and these fine particles may be collected by passing the gases through cyclones or bag filter or wet scrubber or any combination on any or all of these, depending upon the nature and quantity of dust involved.
Process Control :
For any system there is relationship between the product moisture content and exhaust air temperature. Therefore product moisture can be controlled through the control of exhaust air temperature by regulating the flow of heat by means of temperature controller with a thermocouple located in the exhaust air duct. The optimum performance can be achieved if the dryer operates as per design conditions and with constant evaporative load. Any variation in evaporation load due to variation in feed rate or moisture content results in a corresponding variation in exhaust temperature which in turn increases or decreases air heater output and it raises or lowers the inlet air temperature. Thus evaporative load may be controlled by measurement of inlet air temperature using controller with temperature probe located in the inlet air duct and output signal to a variable rate feeder, which generally provides control of the drying system.
Dust Collecting Equipments :
Dust Collecting Equipments :
Exhaust gases from Rotary Dryer contain certain proportion of very fine dust which becomes entrained in the air stream while in contact with materials being dried. A Dust collector of high efficiency cyclone type is used. Even the most efficient cyclone type dust collector will not collect all the dust. Very fine particles which escape the dry collector may be recovered by mean of a wet collector in the form of sludge or alternatively by means of a Bag Filter
Application :
Application :
Rotary Dryers are used to dry Potassium Chlorate, Barium Nitrate, Sodium Chloride, Sodium Nitrate, Ilmenite, Urea Crystals, etc.
