Silica sand rotary dryer

The three-cylinder dryer adopts the advanced technology introduced from Europe; the dryer is assembled by three concentric-cylinders which halved together with different diameters.

silica sand drier structure and the working principle:

The silica sand rotary dryer main part:

1. Dryer body,2.rolling ring,3. Ring gear, 4. Roller,5 .small ring gear, 6.discharging part 7.lifting plate, 8.motor and reduce speed machine,9.Feed chute,10. furnace and other part.

Working principle of silica sand rotary dryer:

The silica sand transport into the hopper by belt conveyor or bucket elevator,And then through the hopper feeder and loading pipes into the feed end .The feeding pipe slope is bigger than the natural inclination of silica sand , so that the silica sand can easy into the dryer.The rotary dryer is a horizontal line slightly tilted to the rotation of the cylinder.Feeding the material from higher part.

The silica sand from the higher end put into dryer, hot air can from the same direction or different direction into dryer. With the turning of dryer the material moving to the lower end,the slowly moving process is drying process, at the same time the wet silica sand full contact hot air and evaporation water, when the drying process finished used the belt conveyor transport out.
