Rotary kilnis composed of cylinder, gears, support
device, kiln liner and kiln tail sealing equipment, kiln head
hood and fuel device.
Rotary Kiln
Product application:
Rotary kiln is a kind of thermal
equipment, heating materials. It is widely applied in the fields
of cement building materials, nonferrous metallurgy, ferrous
metallurgy, refractory material, chemical materials and paper
making.
Rotary Kiln
Product feature:
1. Support device: advanced shaft structure,
automatic temperature measuring device and electrical heating
device.
2. Catch wheel: including mechanical wheel
and hydraulic pressure catch wheel.
3. Gears:Â single or double. The
rotating speed is controlled by regulating motor, DC motor or
variable frequency and speed regulation motor. Be reliable,
energy-saving and efficient.
4. Cylinder tyre bolster: lower bolster has
three types: fixed, zoom and floating. Its structure is simple,
replacement is convenient and it won't hurt cylinder when it
needs a change.
5. Sealing equipment: there are many kinds
for choice according to kiln models, including air cylinder edge
sealing, spring edge sealing, graphite block sealing and
combination for above. The feature is adaptive for cylinder
rotating and swing. And sealing effect is very
good.
6. Kiln head hood:Â including stationary
type and flexible type.
Rotary Kiln
working principle:
The kiln is a cylindrical vessel,
inclined slightly to the horizontal, which is rotated slowly
about its axis. The material to be processed is fed into the
upper end of the cylinder. As the kiln rotates, material
gradually moves down towards the lower end, and may undergo a
certain amount of stirring and mixing. Hot gases pass along the
kiln, sometimes in the same direction as the process material
(co-current), but usually in the opposite direction
(counter-current). The hot gases may be generated in an external
furnace, or may be generated by a flame inside the kiln. Such a
flame is projected from a burner-pipe (or "firing pipe") which
acts like a large bunsen burner. The fuel for this may be gas,
oil or pulverized coal.
Rotary kiln belongs to building material equipment, which
can be divided into cement kiln, metallurgy chemical kiln and
lime kiln according to different materials.
Cement kilnis used for making of cement clinker and
there are dry and wet methods to make cement. Metallurgy chemical
kiln is used for magnetic roasting of iron ore and oxidizing
roasting of chrome and nickel in the steel factory; baking
high-alumina mine in the refractory material factory; baking
chamotte and alumina in the aluminum factory and baking chrome
ore and chrome powder in the chemical plant.
Lime kiln is used for baking active lime and dolomite in
the steel factory and ferroalloy factory.
