Introduction of Rotary Kiln
Rotary kiln is a pyroprocessing device used to raise materials to a high temperature in a continuous process. It is widely used in the fields of cement production, nonferrous metallurgy, ferrous metallurgy, refractory material, paper-making, chemical industry and so on.
Structure of Rotary Kiln
(1) Support device: Advanced shaft structure, automatic temperature measuring device and electrical heating device.
(2) Catch wheel: Including mechanical wheel and hydraulic wheel.
(3) Gears: Single or double; Control the rotating speed by variable motor, direct current machine and frequency variable motor; 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 choices available according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. The feather has strong adaptability to cylinder rotating and swing and sealing effect is very good.
(6) Kiln head hood: Including stationary type and flexible type.
Working Principle of Rotary Kiln
Rotary 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, pulverized petroleum coke or pulverized coal.
Our rotary kiln is made up of the shell, driving device, supporting device, the supporting device with thrust roller, sealing device at kiln tail, movable kiln head and the combustion device, etc.
To maximize efficiency, our rotary kiln incorporates the advanced hydraulic thrust roller device, high measuring precession plunger pump, contact graphite block sealing device, variable speed adjusted valve, and other nationally advanced technologies.
Packaging & Shipping
Packaging Details:
We will load different sizes of packing according to different machine sizes, and the normal packing is in wooden cases. If exported to European countries, wood frame will be fumigation. If the container is too tight, we will use the PE film according to the customer's special requirements.
Delivery Time:
We are based on the actual needs of customers, to carry out tailor-made sales. By senior engineer to design scheme, after receipt of customer deposits began production, regardless of the size of the equipment we can deliver the goods in two weeks, delivered the balance after delivery.
