1. Brief Introduction of bromides Dryer

Sludge paddle dryer dried through heat contacting. There are three types of paddle, round plate type, wedge type and hollow screw type. There could be two shafts or four shafts structure

Largest two shaft paddle dryer could being designed with 200 square meter heating area, largest four shaft type could be 400 square meter heating area.

Heating resource could be hot water, steam or thermal oil. Temperature of heating medium is available ranges from 60-320 centigrade.

Sludge paddle dryer is very compact with less heat loss

2. Principle of bromides Dryer

KJG double paddle dryer is a kind of indirect heated dryer. There is jacket on the body of dryer, hollow paddle strongly welded on two hollow shafts, filling heating medium (could be hot water, steam or thermal oil) in them, wet raw material is heated, dried as well as driven forward by two shafts.

3. Features of  bromides Dryer

1. Drying efficiency could arrives 80%-90%. Heat transfer coefficient K is 100-300Kcai/h.m²℃. Evaporation capacity is 10-30Kcai/h.m².

2. The dryer support continuous operation and batch operation, support vacuum drying for thermal sensitive material and normal drying. Support heating, evaporating and cooling.

3. Thermal oil, steam, hot water and chilling fluid are available to be used as heating/cooling resource

4. Special structure of paddle which has large heating area.

5. Structure of dryer is very compact, almost of the dryer could be transported by normal container.

6. We developed High Vacuum Paddle Dryer which is suitable for hazardous waste or the waste need to recover solvent. We own the patent of high vacuum paddle dryer.

4. Innovation Technology and Reforming Design of  bromides Dryer

(1)Combined with overseas’ technology, our company developed new two shaft and four shaft structure paddle dryer.

(2)The dryer adopt one bearing seat in whole piece, cooling device is available for choice.

(3)Drying chamber, bearing and shaft is available for heat expansion. The dryer is designed with frame which could prevent deforming during transport and lift.

(4)Whole body is strengthened, which could promise a longer life span

(5)The plate paddle adopt integral welding which has better strength. Quantity and form of scraper on paddle will be designed according to the feature of raw material.

(6)Overall size of paddle dryer is very compact, a single unit (with two shaft) could designed with max 250 square meter heating area.

(7)Driving through direct coupling, which is more stable. Direct coupling could prevent swaying or loosen problem coursed of chain driving.

(8)Special installation process makes our dryer has better shaft concentricity, sealing on two ends are better.

(9)Both semicircular pipe jacket or whole body jacket is available for choice.

(10)Different discharging method is available in design according to the features of different raw material. Necessary drying retention time could be promised.

(11)Special design for preventing raw material blocking up during feeding.

5. Safety Method (Optional) of  bromides Dryer

(1) Explosion release: There has two sets of explosion valve on each dryer

(2) Exhausting system: Exhausting through two vacuum pumps, each pump has bigger capacity than evaporation amount. Commonly there’s only one pump working, but when pressure sensor test the inner pressure is larger than setting value, second pump will start to work, and it will stop after pressure drops.

(3) Oxygen content control: Because the paddle dryer is in continuous production and it works under negative pressure, there will be oxygen enter the dryer through discharging port and sealing part. When sensor test that oxygen content is higher than setting value, Nitrogen will be filled into dryer through valves. And the valve closed after oxygen content dropping under control.

(4) It is adopt special sealing method specially for sludge with dangerous solvent. Special seal could reduce air leaking, and promise a better sealing condition.

(5) Safety control of drying temperature: Adopt steam proportional control valve, to promise more accurate temperature control.

(6) Water spraying system: When material has explosive or flammable vapor, there will be equipped with water spraying pipe on dryer. When temperature sensor test the inner temperature is higher than alarming value, water spraying system will work.

(7) Adopt explosion proof gauge and electrical components
