Dolomite Rotary Kiln / Dolomite Calcining equipment
Dolomite Rotary Kiln Introduction:
Dolomite rotary kiln is designed according to dolomite calcination characters and
Pidgeon process requirement. That is the key equipment in the
calciantion process. The dolomite produced by rotary kiln with
stable quality, high activity and low ignition loss that can make
higher magnesium extraction rate and silicon utilization rate to
save running cost. The rotary kiln is the most suitable equipment
for produce magnesium. The new type energy-saving rotary kiln
designed by ZK Corp. has own patent and formed dolomite calcination
standard for magnesium industry in China.

Dolomite Rotary Kiln Structure:
Dolomite rotary kiln is mainly compose of driving device,
supporting roller, catching roller, cylinder, kiln inlet, kiln
outlet and sealing device.
1. 2-3 supporting points can guarantee the contacting surface
between supporting roller and tyre is paralleled with axis line of
cylinder during installation.
2. Supporting device is antifriction bearing (occasionally uses
slide bearing). This design has simplified the supporting device of
supporting roller, and reduced the useless power loss during
operation. It has the features like easy operation and maintenance.
3. Low speed unloading rotation device is designed for easy
installation and commissioning. It also can guarantee unloading
rotation operation during maintenance of main driving system or
other emergency situation. This design can prevent cylinder from
bending and deforming during the temperature is cooling down.
4. Mechanical or hydraulic catching roller is optional according to
different type of rotary kiln. Both them have high accuracy and
reliability, and also make sure evenly attrition of outer circle of
supporting roller and tyre at the direction of complete width.
5. Radial direction contacting type sealing device is adopted at
kiln inlet and outlet. They are perfect suitable for dimension
tolerance of cylinder and skewing movement of cylinder. This
sealing device’s feature is good performance, longer working life
and easy for replacement.
Our Advantages:
1. According to the character of dolomite and its calcination
requirement, the structure of kiln inlet and outlet sections has
been optimized. It can resolve the problem of material returning
back to kiln inlet and the leakage of dust.
2. Inner of the kiln keeps micro negative pressure, dust pollution
is lower.
3. Rotary kiln is even calcination, large capacity and easy to
operation and maintenance.
