Descripción del producto
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: 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: 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.
