High Efficiency Small Electric Lime Plant Rotary Kiln

Lime rotary kiln

According to the calcination character of limestone, lime rotary kiln is specialized design for production of active lime. This type of kiln can work with vertical preheater and vertical cooler to achievethe advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple operation and longer working life. This kiln is very suitable for limestone calcination for industries like metallurgy, chemical, construction materials and etc.

OUR ADVANTAGE

1. According to the character of limestone 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. Evenly heating for limestone, low rate of less calcination and over calcination. Especially suitable for the high activity lime for steel making.

3.Technical configuration is optional: matched vertical preheater can use the high temperature gas from rotary kiln to preheating the limestone from room temperature to decomposition condition; matched vertical cooler can cooling down the high temperature of lime in the shortest time. The process can increase capacity 30% and save energy 40%.

Lime 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.
