The Silica sand triple drum rotary dryer is mainly used for kinds of particle drying, such as sand for premixed dry mortar, casting sand, blast furnace slag for cement, granular clay, flyash, and other particle material which is stable with chemical corrosion, high temperature or dirty smoke.

Raw material with 10-25% moisture content is suitable for this dryer, and not sticky for the drum or lifting blade. The temperature of air flow is less than 70 degree. When there is any special requirement for high temperature drying, the front part of inner drum and lifting blade could be replaced by heatproof steel plate. The product moisture content is adjustable according different requests, even below 1-0.5%.

Silica sand triple drum rotary dryer widly used in:

River sand, Mountain sand, weathering sand, mechnical sand, sea sand,  quartz sand, garnet sand, perlite sand, granulating slag ,   coal gangue etc.

•         Triple pass drum rotary dryer use telescope feed structure, dry the material quickly.

•         Simple design, self-insulation, improve the heat efficiency to exceed 80%

•         Refined experience, stable operation.

•         Good drying performance, coal consumption<8kg when making one ton dried material.

•         The fuel can be coal, oil, natural gas, HFO, diesel etc. dry mass less than 20mm granule and powder material.

•         Save land are for 50% compared to single drum rotary dryer, so construction investment is saved 50%, power consumption saved 60%.

•         Finished product moisture can be adjusted depending on clients requirements.

•         Lower outlet temperature, longer dust removal using life.

•         Drive by tug not gear or opinion.

•         Finished product temperature lower than 60℃, packing can be done continuously.

The drying process of 3 drum dryer is realized like this: material from the feeding end fed into the inner cylinder ,material into the inner tube through the spiral guide plate ,when tube rotating, the material continuously  shifting and longitudinal movement by lifting plate, when the material reach the left of inner cylinder ,due to dead weight, fall into in middle cylinder, then through the guide plate, under the action of rotating cylinder body, material was pushed back in middle cylinder, the material right move under the action of lifting plate until the right end, the material into the outer cylinder under gravity . Raw material falls into outer tube by own gravity. Similarly, raw material turn back and towards the left by screw raising blades in outer outer, until to end of left side, and falls into cylinder of discharging end under the action of feed cone seal. Inside the 1, 2, 3 three concentric cylinders of Dryers subject, there are different numbers, different angles of spiral raising plates and each of ends of the cylinders with guide plates. Telescopic principals short cylinder drying machine through two geared motor 6, drive the driving wheel5 on opposite sides respectively, Make the belting leather 4 rotation around the center. Wet material need to dry  through feeding device, feeding tube to feeding side of internal cylinder 3, the wet material quickly pushed into spiral raising board from spiral guide plate, along with the rotation of cylinder, screw lifting plate located within the four cylinder causes wet material constantly rolling, dispersed to end for vertical movement during lifting. At the same time, heat flow comes from stove successively enter into the inner barrel 3, middle barrel 2, external tube in 1 with material for heat exchange. Due to the metal plate is faster than drying materials in thermal conductivity, barrel of steel and feed plate heated first, and then pass heat to the material in the form of conduction and radiation, material heated, temperature will be up, when temperature rises to the water evaporation, water vapor from the separated material, along with the smoke through the filter into the atmosphere, thus achieve the goal of material drying.
