Three Cyclinder Rotary Sand Dryer Machine Various Capacity For Silican Sand Drying

Description of sand dryer machine:

Triple pass rotary drum dryer Processed Materials:River sand, artificial sand, silica sand, yellow sand, mineral sand, mineral powder, slag, coal ash, coal slag, etc.

Application: Dry-mixed mortar industry, cement, building materials, glass, foundry industry, chemical industry, etc. triple ppass rotary drum dryer has compact structure and covers a small area which is half of the single drum dryer does. The three-drum dryer works reliably with low energy consumption and high heat efficiency which realizes good material drying effect, simple automation control and few operating staff.

Capacity:1-50tones per hour

Heating Fuel:Coal, Gas, Oil, Biomass fuels, Wood,etc

Based on single pass drum dryer, Hengxing equipment also develop triple pass drum dryer to take drum drying technology a step further. Triple pass rotary dryer improves the performance in operation cost, service life, energy efficiency, product consistency.

Triple pass rotary drum dryer has proved its application in building materials, chemical, foundry, cement industry. It is used in the dehydration of dry mixed mortar, silica sand, foundry sand, iron powder, coal gangue, blast furnace slag, fine clay, etc. Final moisture content could be reduced to 0.5-1%. Optimal feeding particles should be below 30mm.

Working Principle of three pass river sand drum rotary dryer machine:

Materials enter the inner side of the drum through the feeding device to realize current flow drying process, then the materials enter the middle layer of the inner wall through the other end to realize counter current drying process. They are lifted in over and over in the middle layer which advance in two-steps forward and one-step back way. The three-drum dryers absorb heat from both inner drum and middle drum, which extend the drying time and realize the best drying condition. Finally, materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain because of their own weight. Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.

Application of three pass river sand drum rotary dryer:

Three pass river sand drum rotary dryer is made by our company used on building materials, metallurgy, chemical industry, cement plant for drying of sand, sawdust, wood shavings, chicken manure, iron ore, limestone slag, coal powder, slag, clay stone,etc. This Rotary Drum Drier is composed of rotary body, lifting blade, driving device, supporting device and sealing ring,etc.
