5-8t/h Three cylinder rotary dryer for drying silica sand with
snall space
Product Description
Three cylinder rotary dryer is widely used in mineral processing,
building materials, metallurgy, and chemical industry, drying a
certain humidity or particle size of materials. The dryer has
strong adaptability to materials, can dry all kinds of materials,
and the operation is simple and reliable.
Working principle:
The raw material sand will be fed into the hopper through belt
conveyor or bucket elevator. Sand rotary dryer is a slightly
inclined rotating cylinder with horizontal lines. Raw material sand
will be fed from the higher end, while hot air enters from low-end,
forming counter-current contact with the drying raw material sand.
As the rotation of the cylinder, raw materials run to the end of
the sand dryer under gravity. Wet raw material, in the course of
the cylinder moving forward, directly or indirectly get heat from
hot air which temperature is more than 500°C, for drying wet
material, and then discharged through the screw conveyor or belt
conveyor installed at the end of discharging part. Sand dryer is
equipped with raising plate on the inside cylinder wall, and the
raising plate plays the role of raising and falling down materials,
increasing the contact surface between material and air flow, to
improve the drying efficiency.
Applications:
1. Powder and particle: Sands, limestone, stones, clay, mineral
filter cake, coal, iron sulphate, filter cakes, fly ash, gypsum
etc.
2. Damp and sticky material: Coal slime, sewage sludge, bentonite,
Kaolin etc.
3. Corrosive material: Distillers ‘grains, Fertilizer, animal dung,
slag etc.
4. Biomass material: Sawdust, wood chips etc.
