Applied material: Kaolin, Dolomite, Limestone, Bauxite, Zinc Oxide, Mangesium Oxide etc
Application: Kaolin Calcination
Kaolin rotary kiln is the main equipment for the kaolin calcination. Kaolin rotary kiln is also called Kaolin calcination kiln, which could be used in the calcination process of zinc oxide, magnesium oxide, bauxite etc. Kaolin rotary kiln by ZK Corp has the following features, high productivity, simple structure, and easy operation etc.
The finished products calcined by Kaolin rotary kiln could be used as the mineral raw material in paper, ceramics, rubber, chemicals, coatings and other industries. Some high-tech fields began to use kaolin as the new materials. In addition, the high temperature resistant porcelain parts of space shuttle and spacecraft are also made up of kaolin.

Kaolin Rotary Kiln is mainly compose of driving device, supporting roller, catching roller, cylinder, kiln inlet, kiln outlet and sealing device.
Its main features are:
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. Certain gap is reserved between tyre and cylinder. After thermal expand of cylinder, the tyre can tightly stick on cylinder for strength it.
3. Gear is split type combination structure which is assembled with cylinder by spring boards. The features are easy for installation, steady transmission.
4. 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.
5. 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.
6. 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.
7. 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.
