Product Info: Rotary Drum Dryer also known as a rotary kiln, is employed to reduce or minimize the moisture content of agro and forest waste, it is done by bringing it into direct contact with heated gas. The rotary dryer is made up of a large, rotating cylindrical tube. The dryer discharge end is lower than the material feed to convey the material through the dryer under gravity.
Rotary Drum Dryer is suitable to dry raw material which contains high moisture up to 50% and more. JK make CE Certified Rotary Drum Dryer is special designed to reduce or minimize the moisture content of agro and forest waste to 10% or less for briquetting, JK Rotary drum dryer combines the function of drying and cooling, thus save 30-50% energy.

How it Works
Hot air is generated by wood/ Briquettes. Material is conveyed by screw at feeding point. Material is spreaded by lifters in horizontal shell. Hot air is sucked by fan through shell in the presence of wet material. With the rotation of cylinder, the material flow down to the lower end with the effect of gravity and discharge after drying, at end point material comes out with the help of cyclone & Rotary valve with required moisture. Evaporated moisture goes in atmosphere by sucking fan.
Various models of Rotary Dryer are available basis on Moisture content and production requirements. Complete System of Rotary Dryer is automated where moisture content is adjustable.
After the damp raw material is put into the dryer from one end, it is turned over through string-up rake inside the cylinder and distributed uniform in the dryer and contacted with counter current hot air fully.
It speeds up heat and mass conducting of dry. During the period of dry raw material is effected by stirring-up rake with gradient and hot air. It can be moved and passed through the dry region and to star valve and then discharge the finished product.
During the Drying Process, the best moisture content to pellet and briquette is about 13-15% and 11-12%, the function of the Rotary Dryer is to make the crushed pieces with suitable moisture.

Application of Rotary dryer : It is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryer can be used for drying many kinds of materials and with convenient and reliable operation; therefore, it has been widely used. Working Principle of Rotary dryer : After wet material is put into the hopper, the stove generates hot wind. Then wet sawdust is sucked into the pipes by the exhaust blower(fan) , flowing and go though the curving pipes and buffer(drying chamber) of dryer, thus the wet material is dried, and the dried material is discharged from the outlet with air lock. This type of dryer is suitable for drying heat sensitive material which is light and small like sawdust, rice shell, milled stalks etc. General Wet material can be dried in a few minutes. Compared with rotary dryer, it has the advantages of low energy comsumption, low cost.

Product info: turbo dryer is also known as column turbo dryer (ctd) which is utilized for the drying purpose for all such raw material which is having high moisture content up to 30-35% such as fibrous material such as bagasse, jute, coir pitch, efb palm waste etc from which moisture evaporates at the acceptable limit of 12%. General description: The system consists of screw conveyor, vibrating screen, feeding hopper vane guide, conveying line including insulated drying column and conveying line through which wet or moist material is conveyed with hot air. A powerful low pressure open wheel centrifugal fan assures significant resilience time for removal of excess moistures. Material is conveyed to cyclone and discharged through air tap duct. Technical specifications: Moisture evaporation capacity : 450 kg. /hr. Output : 1500 kg. /hr. Maximum input moisture : 35% Outlet moisture :15% Centrifugal fan motor : 15 hp Vibrating screen : 2 hp Screw conveyor motor : 2 hp How it works: Hot air temperature is kept according to the requirement from moisture of material. Your flue gas temp of 150 deg cent will not serve the purpose as material, even at 30-35 % moisture level, will require 300-350 deg centigrade. Also, for 50 % material, the temp may be used at about 500-550 deg cent. Flow rate will be around 10, 000 cmh. The dryer is flexible at the joints, i.E., at the bends. So, you can take a 90 deg turn at any of the joints. Hence, including hag, the dryer size could be 30 x 15 or 25 x 25 ft. With a height of about 29 ft. We recommend to use hot air generator as source for evaporating moisture from biomass so that the briquettes manufactured from such biomass will be proved to be good biofuel in boilers We use a ss chicken mesh at the outlet of furnace, which is sufficient to arrest any leftover spark in the flue gas, after it has travelled through 2-3 ups & downs in the furnace. With 50 % input and 14 % output of bagasse, ctd dryer will give an output of approx. 1500 kgs/hr. -
The material inside the rotary dryer has heat exchange with the high temperature flue gas through shell rotating and material lifting by lifter. The rotary dryer has many good characters like: high efficiency, big capacity, high running rate, saving energy, easy for maintenance, long working life. Variety angle of the lifter will increase the heating exchange rate and short drying time. That is widely used for drying lay, slag, fly ash & etc. After the welding of bases for supporting devices of supporting roller and catching roller, vibration aging treatment should be applied for remove the welding stress. Then, use vertical lathe and boring-milling machine for integration fabrication. This process can guarantee the requirement of fabrication precision and dimension & location tolerance. Installation accuracy of rotary kiln is obviously improved. Rotary dryer’s advantages as follows: 1. Variety angle of the lifter will increase the heating exchange rate and short drying time. 2. High drying efficiency, big capacity, high running rate 3.Compact structure, operation stable, easy maintenance Rotary dryer is mainly compose of driving device, supporting roller, thrust roller, cylinder, kiln inlet, kiln outlet and sealing device. 1. 2-3 supporting points can guarantee the contacting surface between supporting roller and tyre is paralleled with axis line of cylinder during installation. 2. Supporting device is antifriction bearing (occasionally uses slide bearing). This design has simplified the supporting device of supporting roller, and reduced the useless power loss during operation. It has the features like easy operation and maintenance. 3. Suitable shim between tire and shell will ensure the tire ring on the shell tightly to increase the shell strength. 4. The main driving system uses new type AC variable frequency technology. Compared with electromagnetic speed control and DC speed control, that can save energy, have large range & high precision of speed regulation, high efficiency and running smoothly. Radial direction contacting type sealing device is adopted at kiln inlet and outlet. They are perfect suitable for dimension tolerance of cylinder and skewing movement of cylinder. This sealing device’s feature is good performance, longer working life and easy for replacement.
