The Influencing Factors and Functions Of Kiln Coating Of Rotary Kiln

The rotary kiln is widely used in power plant engineering. And the kiln coating is introduced here.
The forming for kiln coating has many influencing factors. There are three main factors.
1 The chemical composition of materials: The kiln coating is the outcome of liquid phase to solid phase. If there are more aluminous and ferruginous composition, it is easier to forming the kiln coating. But if one kind of aluminous and ferruginous composition is much, it is difficult for the forming of kiln coating.
2 The temperature of flame: If the temperature is too low, it is difficult to form the kiln coating. If the temperature is too high, the kiln coating could form but it is easy to drop out.
3 The shape of flame: The short, and broad flame is erodent to the kiln coating. And the long flame is beneficial to form the kiln coating. But the heat will be scattered.
In the course of operating, the users should pay attention to the flame shape and flame location and strictly supervise the production.
And the functions of kiln coating has the following items.
1 It could protect the firebrick from high temperature and chemical attack.
2 It could store the heat, reducing the heat loss and increasing the heat efficiency of rotary kiln.
3 The rough surface of kiln coating could reduce the flow speed and prolong the reaction time of materials.

The Comparison of Portal Scraper Reclaimer and Boom Scraper Reclaimer

图片
The portal scraper reclaimer and boom scraper reclaimer are the main types. The differences are as follows: 1. The portal reclaimer has reasonable structure. The partial weight of portal frame and scrapper reclaimer is supported by the wall(blocking materials). In this way, the stress state under the central cylinder, and the running of the portal scraper could operate smoothly. And the boom scraper reclaimer's load could be transmitted to the central cylinder. In this way, the design and manufacturing difficulty is large and the stability of the equipment is bad. 2. The portal reclaimer has compact structure, and there is no need to design the balance weight. The space occupied under the portal reclaimer is small. The boom reclaimer should be designed with large balance weight. 3. The portal reclaimer need the circle track in the wall(blocking materials), and the related cost of setting circle track. The balance weight load of the boom scraper reclaimer is central under t

The Analysis Of Advantages And Disadvantages On Boom And Portal Bucket Wheel Stacker Reclaimer

图片
As we all know, the stacker reclaimer coordinates with belt conveyor to complete the handling process of materials in most conditions. The bucket wheel stacker reclaimer, as one of the mining equipment , is mainly used in handling materials. According to the structure form, there are boom bucket wheel stacker reclaimer and portal bucket wheel stacker reclaimer. The boom bucket wheel stacker reclaimer is widely used in port, coal storage yard, earthwork, coking plant, cement plant and etc for handling coals, ores, and other materials. The portal bucket wheel stacker reclaimer is mainly used in power plant. The boom bucket wheel stacker reclaimer handles materials through the rotation. So it is necessary to set the large rotating bearing, which increases the cost. The portal bucket wheel stacker reclaimer handles materials along the straight line without the large rotating bearing, which could save the cost. The boom bucket wheel stacker reclaimer could handle materials over 90 d

The Features Of Different Apron Feeder

图片
In general, the apron feeder could be divided into three types including heavy, medium, light type, which is the continuous transportation machinery widely used in mining, metallurgy, construction materials, ports, coal and industrial and mining enterprises. The apron feeder is mainly used as the storage bunker to continuously supply the materials or transfer large material to crushing machine or batching apparatus. The apron feeder is one of necessary machine for handling materials in the process of continuous production. Sometimes some EPC companies would choose stacker reclaimer, belt conveyor, stone crusher and etc to complete the transportation of materials. The light apron feeder is suitable for transporting materials under 160mm granularity in short distance. It is used for continuous feeding in mine, mill plant, chemical industry, cement, building materials. The light apron feeder could be installed horizontally or obliquely. The maximum inclination degree is 20, which is su
