ZK Corp could also meet different needs from different customer to produce
Non-standard rotary kiln. Rotary kiln is composed of cylinder, gears, supports device, kiln liner and
kiln tail sealing equipment, kiln head hood, and combustion.
Cylinder as heated pivoting part, made of high-quality carbon steel
plate, is supported on the first or some gear in order to control
the turning of cylinder. Gearing gyrate according to
process-required rotating speed by ring gear in the middle of
cylinder. Because of the need of installation or maintenance,
bigger rotary kiln has auxiliary gears, which makes cylinder gyrate
more slowly. To prevent cold air come in and dust overflow, the
reliable kiln tail and head sealing equipment is installed on feed
and discharge end.
Rotary kiln is thermal equipment to heat materials. It is widely used in the
fields of cement, nonferrous metallurgy, ferrous metallurgy,
refractory material, chemical, and making-paper.
1. Support device: advanced shaft structure, automatic temperature
measuring device and electrical heating.
2. Catch wheel: including two kinds mechanical wheel and hydraulic
3. Gears: single or double. Control the rotating speed by variable
motor, DE machine and frequency variable motor. Be reliable, energy
-saving, and efficient.
4. Cylinder tyre bolster: lower bolster has three types: fixed,
zoom and floating. The structure is simple, replacement is
convenient and won't hurt cylinder.
5. Sealing equipment: there are many kinds for choice according to
kiln models, including air cylinder edge sealing, spring edge
sealing, and graphite block sealing and combination for above. The
feather 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 is usually working as following : The kiln is a cylindrical
vessel, inclined slightly to the horizontal, which is rotated
slowly about its axis. The raw material to be processed is fed into
the upper end of the cylinder. While the kiln rotates, material
gradually goes down towards the lower bottom, 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
