high efficiency best quality sawdust/wood chips/silica sand/coal
rotary drum dryer
Rotary dryer description:
Explains:This series depending on the practice in sand and stone
production, absorbing the leading technology home and abroad, and
is widely used in sand making industry.It is of high efficiency and
has the features of easonable structure,high capacity and low
consumption.It can make final products free from dirt and
impurities and reduce the high quality sand loss.
sawdust/wood chips/silica sand/coal rotary drum dryer
Mini rotary drum dryer machine is widely used in building
materials, metallurgy, chemical industry and cement industry, which
is widely used to dry the stuff such as limestone, coal powder,
slag and clay.
rotary dryer can be widely used in:
1. The coal industry: Coal slime, coal, flotation clean coal, mixed
clean coal etc.
2. The construction industry: Blast furnace slag, clay, Peng Yun
soil, lime stone, sand, quartz stone etc.
3. Ore processing industry: Various metal concentrates, slag,
4. Chemical industry: Non-drying heat sensitive materials
sawdust/wood chips/silica sand/coal rotary drum dryer feature
1. Rotary dryer has Strong anti overload ability, large handling
capacity, less fuel consumption, low dry cost.
2. Adopt downstream drying method, the hot air with wet materials
enter into the dryer by the same side, can use the high temperature
air to achieve very high evaporation strength, the exist
temperature of dryer is low, the thermal efficiency is high.
3. According to different materials' properties change operation
parameters, make the material in the dryer cylinder body can form a
stable all broken fabric curtain, qualitative heat is more fully.
4.New feeding and discharging device eliminate the feeding jams,
discontinuous, uneven and returning charge etc. Phenomenon, reduce
the load of dust removal system.
5. New internal structure, strengthened the already scattered
materials' cleaning and heat transfer effect, eliminated the sticky
phenomenon in cylinder
body's inner wall, make material moisture, sticky adaptability more
6. rotary Dryer has realized "zero horizontal thrust", greatly
reduce the wear of block roller, cylinder's operation is smooth and
7.rotary Drying machine adopts "center-adjusting roller device",
make the cooperation of roller and rolling ring always show linear
contact which greatly reduces the wear and power consumption.
8. According to customer's request control product size and
moisture, when dry slime, the moisture can reach below 8%, particle
size can be controlled below 8mm.
sawdust/wood chips/silica sand/coal rotary drum dryer principle
Wet materials is carried to hopper by belt conveyor or bucket
elevator, and added in from the top of feed opening. The cylinder
is the main body of the dryer, the material through internal
cylinder will contact with the hot air through it in the form of
direct flow or reverse flow, or make an efficient contact with the
heated wall surface and be dried.
After drying, the products will be discharged from the bottom of
the other end. In the course of the drying, the materials will move
from higher end to lower end in the action of gravity with the help
of the slow turning of the cylinder. The cylinder wall is equipped
with downstream shovelling plate, which constantly lift the
materials and sprinkling it down, so that the heat contact surface
of materials is greatly enhanced, improving the drying speed and
driving the materials to move ahead. After heat carrier (hot air,
flue gas) drying material, the waste gas is evacuated after the
carried dust is collected by the cyclone dust collectors.
