WELLINE is China's Leading and Professional Manufacturer Limestone Rotary Kiln

1.Brief Introduction of Limestone Rotary Kiln:
1). 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.

2. 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 high-started 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.

3. 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.

Notice: any technical change shall not be advised additionally.

5. 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.

6. Spare Parts of Rotary Kiln:

7. Warranty of Rotary Kiln:
1. One to three Years (Calculated from the goods arrived the destination port.) If any parts (excluding easily damaging parts) are found defective in quality in the first year, we shall replace it free-of-cost. After one year, parts can be replaced on favorable payment basis.
