Rotary Kiln

Limestone Rotary Kiln Brief Introduction:

1. Limestone 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 kiln is used for making of cement clinker and there are dry and wet methods to
make cement. Metallurgy chemical kiln is used in metallurgy industry and ironworks for
lean iron ore, chromium ore and ferronickel ore calcimine.

2. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material
industry, calcimine of calotte and aluminum hydroxide in aluminum manufacturer,
claiming of chrome sand ore and chrome powder ore in chemical plant.

Structure Features of Rotary Kiln:

The kiln shell is made of rolled steel plates; its structure is optimized by computer software
, and features" longitudinal flexible and transverse rigid”, which improved the loading of
supporting device and stability of refractory lining,

The supporting roller bearings features smaller width over diameter ratio L/D, leading to
its higher reliability. The special highstarted torque motor for cement industry rotary kiln is
applied for driving system. The sealing of labyrinth plus spring pressing with asbestos
heat isolation layers attached, is applied higher so that reliability and longer service life
of sealing are achieved.

Application of Rotary Kiln:

1. Rotary kiln is commonly used in the production process of catalytic agent, molecular
sieve and zinc oxide, etc. As a result, you can find a rotary kiln in variety of industries, like
steel annealing and nonferrous smelting industries, metallurgy and chemistry fields, and
building industries, and more.

2. Rotary kiln system, which is also called a rotary calcine kiln, is a commonly used building
material machine. Classifying by material properties, a rotary kiln falls into cement kilns,
metallurgy chemical kilns, and lime kilns.

Working Principle of Rotary Kiln:

1) With a certain slope to the level, the whole kiln body is supported by rollers and fitted with
thrust rollers to control up and down movement of the kiln body.

2) Besides main driving unit for driving system, it is also fitted with the auxiliary driving unit
so as to ensure the kiln body still can rotating when the main motor is powered off and
prevent it from deforming.

3) The kiln head adopts housing type sealing and kiln rear uses axial contact sealing unit
so that reliability of sealing could be ensured.

Our company also produce other kind of heavy euipments, and the productions are all in
good quality . If need , please contact me without hesitation. Hope to cooperate with you.
