200-300 tons per day of lime rotary kiln a complete production line price

As early as the Ming Dynasty, the Chinese people have begun the preparation of lime calcination of limestone, used in construction, and thousands of years ago has a history. Therefore, Chinese people already have a mature lime limestone firing techniques.

First, the most advanced lime rotary kiln -roary kiln

After long years for baking active lime and light burned dolomite production technology continues to progress, from the old shaft kiln to shaft kiln, to the large-scale rotary kiln, lime kiln, active limestone kiln, not only to achieve the Nissan production capacity in 1000 tons, to meet the needs of modern industry, calcined intelligent control technology, to avoid the traditional kiln burnt rate, the high rate of students burned, while greatly reducing energy consumption

Currently, 200-300 TPD lime rotary kiln production line has become the domestic market common lime production project specifications. According to its energizing effect is divided into different gas kiln, coal-fired rotary kiln, rotary kiln fuel mix.

Second, 200-300 tons of lime kiln a complete production line process

Lime rotary kiln a complete production line mainly consists of a vertical preheater lime kiln, vertical cooler composed of lime rotary kiln production line of the a complete process as follows:

Active lime calcining system is composed of a vertical preheater, rotary kiln, vertical cooler composed of material from the preheater at the top of the silo slip through tubing into the cutting body preheater, preheater materials channel provided with low pressure drop within the beam, can effectively reduce the resistance loss of the flue gas, reducing power consumption and exhaust equipment, flue gas after the warm-up through the limestone dust bag filter by the fan into the atmosphere, while the active lime kiln by the incoming the high temperature flue gas material preheated to 900 ℃, so that partial decomposition of limestone, then followed by the hydraulic push rod is pushed into the kiln smoke chamber and then into the tail of the rotary kiln, the rotary kiln calcination and then discharged into the vertical cooler inside, the cold air blown by the fan, the material was cooled to room temperature + 80 ℃ below the discharge cooler, cold air in the cooler is heated while the material through the kiln into the kiln hood, a secondary combustion as fuel air.

Which mainly comprises a transmission gear, supporting roller device, carrier gear wheel supporting device, cylinder, head kiln, kiln tail and seals and other components:

1. the supporting device: Advanced shaft structure, automatic temperature measuring device and provided with electrical heating device.

2. gear wheel supporting device: divided into mechanical and hydraulic thrust gear wheel categories. Hydraulic block device is equipped with advanced hydraulic control system.

3. transmission: with a single drive and dual drive. Speed motors, DC motors or variable frequency motor speed control speed, reliable operation, energy efficient.

4. with plate cylinder wheel: wheel taken off the plate as fixed, adjustable and floating pad, has a simple structure, easy maintenance and replacement, not to hurt the removable cylinder and so on.

5. the sealing device: There are many forms of alternative seal according to different type of kiln design. Clamping cylinder seal, spring-loaded seal, seal weight graphite block, graphite block sealing spring, scale films labyrinth seals, labyrinth seals and axial seal combination of the above forms and now more commonly used flexible sealing, etc., which is characterized by traverse cylinder and swing adaptability, good sealing effect.

Third, 200-300 tons of lime kiln how the selection?

CHAENG ( Great Wall Machinery ) 200t / d lime rotary kiln production line matching is: φ2.8 × 50m rotary kiln, supporting coal mill model Φ1.7x2.5m, to obtain satisfactory operating results.

Fourth, the CHAENG of mechanical rotary kiln lime production capacity to fight to win the praise of customers around the world

With large-scale lime industry and modernization needs, Great Wall Machinery launched a large package lime rotary kiln production line of large-scale, in-line production capacity up to 1500t / d, its main specifications are: Nissan 300 tons of lime kiln, Nissan 200 tons lime kiln, lime kiln, Nissan 600 tons, widely used in metallurgy, iron and steel, chemical, refractory, ceramic, paper industry.

With the ever-increasing ability to innovate, prominent flexible customization capabilities, maturing delivery capabilities to win the trust and support customers around the world, the CHAENG will always first-class products, improve service and sincere cooperation with domestic and foreign merchants, harmony and win-win development of.
