Automatic Paddle Blade Industrial Drying Equipment For Sea Sand

Automatic Paddle Blade Industrial Drying Equipment For Sea Sand
 

Equipment Introduction:

Automatic paddle blade industrial drying equipment is one kind of heat conduction based horizontal 
mixing and drying equipment. The required amount of heat for this equipment is rely on the indirect
heating of heat conduction, so the air is not required or only little air is required in the drying process to 
take the moisture away, which greatly reduce the heat waste being taken away by the air and the 
utilization of heat is improved, it’s one kind of energy saving dryer and suitable for drying particles, 
powder and paste material. PLC automatic control system can be adopted in the entire system, which 
contains advanced testing equipment, thermometer, temperature control device, fault alarm and 
automatic shutdown protection etc.
 
Working Principle:

KJG hollow paddle blade industrial drying equipment is one kind of low-speed mixing type and 
continuous indirect heating equipment to conduct heat to dry (chill-down) materials by the hollow blade 
of sector structure. There are two pieces of parallel rotation axes of mounted staggered blades in the 
jacket structure cylinder of tis equipment, many pieces of hollow blade of sector structure mounted on 
each axis staggered by a certain interval, there are two kinds of blades (feeding shear plane and return 
shear surface), the axes rotate at low speed. The hot medium enters into the hollow rotary axes and 
blades through the rotary joint installed at the end of the rotating axes, be dried after heating, which will 
be discharged out of dryer through the rotary joint. In addition, the hot medium will be led into the jacket 
structure. Materials will be fed constantly through the feeding end, and which will be stirred and mixed 
through blades, and materials will be dried through heat conduction between the blades and jacket
structure at the same time, and materials will be discharged while it’s being heated. The retention time 
can be adjusted by changing the height of the overflow weir. The raw materials will be fed into the dryer 
and will be conveyed the discharge port to be discharged out through the hollow paddle blades. The 
materials will be stirred by the hollow paddle blades during the conveying process, meanwhile, which 
will be dried through evaporation by the simultaneous heating of the hollow paddle blades and jacket 
structure, with high thermal efficiency. The continuously variable transmission is adopted and connects 
with the gear box in this dryer, 5-20rpm, the rotation speed can be adjusted according to material 
properties. The air is being exhausted from exhaust vent.
