Product Description

Discription of rotary kiln

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 for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory

 

Baking high-alumina mine in the refractory, baking chamotte and alumina in the aluminum factory and baking chrome ore and chrome powder in the chemical plant

Rotary dryer is used widely. It can be used to dry construction sand, abandoned tailings, new energy material, ore, powder and coal. The dry selection shall consider the local fuel, place and environmental protection.

 Structural Featuers of Rotary Kiln

1. Supporting device apply rolling bearing ( few with sliding bearing) to simple the bearing structure to slow down the kiln power consumption and it also improve the maintenance and inspection conditions.

2. Catch wheel: including two kinds mechanical wheel and hydraulic pressure

3. Gears: single or double. Control the rotating speed by buncher, DE machine and frequency variable motor. Be reliable, energy-saving, and efficient.

4. Cylinder type bolster: lower bolster has three types: fixed, zoom and floating. The structure is simple, replacement is convenient and won't hurt cylinder.

5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. The feather is adaptive for cylinder rotating and swing. And sealing effect is very good

Principle of Operation

The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal.

A Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include:

 

   Cement

   Lime

   Refractories

   Metakaolin

   Titanium dioxide

   Alumina

   Vermiculite

   Iron ore pellets

Characteristics of Rotary Kiln:

1. Rotary kiln is a kind of pyroprocessing device mainly used to sinter cement clinker. Both dry process and wet process are applicable.

2. It is widely used in metallurgy industry, chemical industry, cement industry, building industry, etc.

3. As a professional rotary kiln manufacturer in China, we adopt advanced contact type graphite block sealing device and hydraulic catch wheel device to ensure the stable running of kiln.

4. Through precision measuring and infra-red scanning, the whole sintering process can be monitored.

5. Our rotary kiln has the features of reliable performance, easy operation, low energy consumption, and high productivity, etc.

6. Compared to the output and energy consumption of other equipment of the same specification, the output of our rotary kiln has increased by 6-10% and energy consumption has reduced by 16%.
