Sponge Iron Rotary Kiln/Sponge Iron Kiln Production Line With Top Quality and Competitive Price

Cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment of the new dry type cement production line. This equipment is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln.

Features of Rotary Kiln:

1) The rotary kiln is an inclined rotary cylinder, the raw material enter the cylinder through the high end of the machine,then move in with the movement of of the rotary kiln. Therefore, the rotary kiln is a conveying equipment.
2) Rotary kiln is a combustion device.

3) Rotary kiln has the function of heat exchange.
4) Rotary kiln has the chemical reaction function.
5) The rotary kiln has the function of degrading and re-using the waste.

Introduction:

Sponge Iron Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and fuel device.As a heated pivoting part, cylinder is made of highquality carbon steel plate and supported on the support device by wheel belt. There is mechanical or hydraulic pressure catch wheel on the first or several support device in order to control the turning of cylinder. Gears make cylinder rotate according to processrequired rotating speed through the ring gear in the middle of cylinder. Because of the need of installation or maintenance, the bigger rotary kiln has auxiliary rotary gears, which makes cylinder gyrate more slowly. To prevent enter of cold air and dust overflow, the reliable kiln tail and head sealing equipment are installed on feed and discharge end.

Application:

Sponge Iron Rotary kiln is the Thermal Equipment, heating materials, in cement industry for calcining clinker.It is also used in various industries, such as cement, nonferrous metallurgy, ferrous metallurgy, chemistry, building, refractory material, environmental protection, etc.

Working Priciple:

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.
