Product Description

Description of Lime Vertical / Shaft Kiln:

Lime is used for producing cement for the construction industry. Lime is very important for many other uses and chemical applications, to produce gypsum wallboard or drywall panels, to neutralize toxic chemicals, for air pollution control scrubbing systems, for neutralizing the acidity of soil for agricultural, and Vertical Lime Kilns are used for the production of sugar. Lime is used for pigment in paints.

Working Principle of Lime Vertical / Shaft Kiln:

Large 1,000+ ton/day capacity Vertical Lime Kilns are possible, are very energy efficient and easy to operate. Minimal maintenance is required, because the limestone is brought to the top and into the kiln. Then the limestone is burned (calcined) for a specified time of hours to produce powdered lime. Then the lime is withdrawn at the bottom of the vertical kiln. 

The withdrawal at the kiln bottom regulates the gravity flow of limestone and controls the calcining retention time in the kiln. A clinkergrinding mill grinds any remaining chunks of limestone into powder. The lime is then transported by truck trailers or by rail cars. White cement is now very much in demand by the construction industry.

Advantage Of Ours Kiln:

1.Rotate to distribute raw materials evenly,so it can calcining evenly,to improving the quality of finished products.
2.The floor area is small and the sealing is good. It can effectively avoid the exhaust of thermal waste gas without environmental pollution.
3.Rotary discharge, increase stability, to avoid the loss of heat.
4.The temperature and output can be adjusted freely.
5.Automatically control the best air distribution and reduce the incomplete combustion loss of fuel.
6.the automation level is high. The adjustment, control and alarm of operation of production system are centralized controlled by PLC in the main control room, with few on-site operators and high labor efficiency.
7.We have 30 years experience in the production of lime production equipment. There are numerous successful cases at home and abroad. The quality is assured and the service is satisfactory.

Parts of Shaft Kiln:

1. Feeding system: lifting raw materials to the top of the kiln, rotating the raw materials.
2. Calcining system: shaft kiln body, including preheating zone, calcining zone, cooling zone.
3. Dedusting system: collecting dust and ensuring zero pollution emission.
4. Discharging system: Rotary discharging, fast speed, large output, transport to finished product warehouse.
5. Control system: Automatically control the operation of each part of the system.

\t\t\t\t\t\t\t\t\tAbroad Installation \t\t\t\t\t\t\t

The installation quality of the kiln will affect the kiln's working life and the quality of the finished lime. We will dispatch engineers to install on site, including follow-up commissioning and training.

Applicable Materials

Shaft kiln can use a lot kind of raw materials, because raw materials composition and physical and mechanical properties are not the same, the materials chemical composition and impurities must have certain requirements in order to produce good finished product.

\t\t\t\t\t\t\t\t\tPacking and Shipping \t\t\t\t\t\t\t

The shaft kiln's parts are relatively large and good packaging and shipping are necessary to ensure product transportation safety and reduce freight costs.
