Industrial Three Cylinder Silica Sand Rotary Dryer Coal Slime Clay Soil Drying Machine

Product Description of small rotary dryer :

Rotary dryer  , also known as drum or drum dryer drying equipment, is the most common and widespread application in mining industry. It is widely used to dry magnetic metal and nonmetal materials, floating clay ore and cement, coal slurry and other industrial materials.   Rotary dryer   is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover, etc. Compared with general dryers, it reduces the coal and power consumption above 10 to 15% and increase the output above 10 to 15% At present.

Working principles:

Wet material from the belt conveyor or bucket elevator to the hopper, and then by feeder feeding through the feeding device into the terminal. Drum dryer cylinder into a slightly tilted to the horizontal rotating cylinder. Adding material from the higher end, low-end entry by the heat carrier, and the material into a counter-current contact, but also heat carrier and the material together and flow into the cylinder. With the rotating cylinder, the material runs by gravity to a more bottom end. Wet material in the cylinder body to move forward the process, directly or indirectly heating the heat carrier, the wet material to dry, and then the discharge end by the belt conveyor or screw conveyor sent. Tumble dryer wall of the cylinder body with lifting plate, its role is to copy the material up and planted, so that the surface of the material increases the contact with the air flow to improve drying rate and to promote material progress. Heat-carrier is generally divided into hot air, flue gas. After heat-carrier around cylinder dryer back then, generally require cyclone trap the gas inside the material brought down. For further reduction of dust content in exhaust gas should be handled through the bag filter before discharge.

Application of Sand Dryer:

1. Sand Dryer is widely used in a variety of materials drying operations. As reliable operation, convenient operation, strong adaptability, large capacity, it is widely used in metallurgy, building materials, food, light industry, chemical industry, coal, medicine and mining industries. 

2. Sand Dryer is suitable for drying granular materials in general. It can also be mixed with some materials by drying sticky paste materials or materials with higher water content. Commonly used in dry sand, slag, coal, animal waste and so on.

Friendly tips: Because of the different requirements for the purity and whiteness of quartz sand, our factory can customize the 304 stainless steel dryer according to the user's needs. The stainless steel dryer has the advantages of non-pollution materials, friction resistance and other inherent advantages. . And the dry quartz sand heat source generally uses natural gas, liquefied gas, methanol and other heat sources that will not affect the whiteness of the sand.
