Product introduction and application

The Best Quality Limestone Rotary Calcining Kiln For Sale in Chile is widely used in the fields of building materials, metallurgy, chemical industry, environmental protection, etc. It can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to the different materials processed. The cement kiln is mainly used to calcine cement clinker; In the process of non-ferrous and ferrous metallurgy, such as iron, aluminium, copper, zinc, stannum, nickel, wolfram, chromium, etc., the rotary kiln can be used to sinter and roast ore, concentrate, intermedium, etc.; The lime kiln is mainly used to calcine limestones.

Working Principle

The main part of the ebullience calciner is composed of small-diameter cooling coil pipes. The 

heat transfer oil is piped into coil pipe and releases the heat into the furnace after exchanging 

heat. Roots blower is equipped at the bottom of the ebullience calciner, which can blow the cold air into the furnace, making the powder boiling in the furnace. And at certain temperature, the 

powder, which has been dried, becomes light that it can flow to the outlet automatically. The 

quality of the gypsum powder produced in this way is better and the content of crystallization 

water is high, and easy to control the time of solidification. In addition, the machine is equipped with dry electrostatic precipitator, and the dust removal efficiency reaches over 95%, eliminating the dust pollution. 

The Rotary kiln is mainly composed of kiln shell, refractory bricks, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln.

1. Supporting device: advanced shaft structure, automatic temperature measuring device and electrical heating.
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. Kiln shell tire 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 sealing effect is very good.
6. Kiln head hood: including stationary type and flexible type.
