Product Decription

Three-drum dryer also called three-cylinder dryer, enjoys the Germany advanced technology.

The three-drum dryer is made up of three layers of sleeves: internal, middle and external one. Both the internal and middle drums are two-dimension ones and the external drum is a vertical one, which makes the most use of the drying drums.

The three-drum dryer's drum length is 25%-35% of the monocular dryer's, thus decreasing the covering area of the machine.

Three-drum dryer or three-cylinder dyer is mainly used to dry granular materials with certain humidity and particle size, such as yellow sand, foundry sand, slag, coal cinder, clay with small particle size and other granular materials that resist to high temperature, dust and smoke.

Moisture content of materials after drying can reach 1 to 0.5 % or below. It is one of the wet materials drying equipment, which is highly efficient and energy-saving product improved on the basis of single-cylinder rotary dryer. After application of various enterprises and industries, three-drum dryer has achieved good results and well received by various customers.

Three-drum dryer has improved internal structure of monocular dryer, which prolongs the time of pre-drying of wet materials and wet materials in the machine, thus improving 50% to 80% of production capacity compared with original monocular dryer.

Working principle of The sand dryer:

Special three tube structure, it formed a oneself insulation system through the inside cylinder and the
middle cylinder was surrounded by the outside cylinder, the surface of the inside and middle cylinder
dryer release invoved in the outside layer in the cylinder materials heat exchanger, thus the outer tube
lie in the heat flow low-temperature terminal. So the cooling area and heat loss of the cylinder is
decreased obviously.

Heat Source

The heat source of the dryer is coal, electricity, gas, etc.Material hot atmosphere flow during drying and radiant, hot air drying cylinder is the heat flow from the tail, to move forward with a good contact with the material, through the heat conduction, convection and radiation heat transfer make full use of;Pass heat directly to the material, make the material moisture to evaporate in the cylinder body are constantly being, into the mouth of the wind device take out a large number of moisture, wet, prevent secondary pollution caused by the dust outside;Through internal spiral stirring, scavenging, copying plate, press the material movement, complete the drying process;Reverse flow dehumidification to avoid reducing repeat drying procedures.
