The Problem Analysis Of Bucket Wheel Excavator In China

The bucket wheel excavator does not travel when excavating the materials. The compound motion of rotating of bucket wheel and cantilever crane helps to excavate the materials. The materials would drop to the conveyor belt receiving the materials. And then the materials would be transported to conveyor belt to the transport machines. In general, the bucket wheel excavator has a long distance in aspect of technology, manufacturing level compared with advanced countries. The types and quantities could not meet the demands of open mining industry. The following problems exist. 
The bucket wheel excavator and its supporting auxiliary equipment are complex. There are some limitations in the usage.
The equipment is bulky. The low mobility and poor flexibility are main problems. 
The digging force is small. For the large and hard rock, the direct operation is more difficult, generally not suitable for use in hard rock.
The initial investment cost of bucket wheel excavator is large with long preparing time, complex design.
The bucket wheel excavator belongs series operation. If the system could not guarantee the stability and reliability, continuous mining process system will lose its advantages, failing to achieve the desired goal.
Bucket wheel excavator is special equipment. The work devices generally could not be replaced.
At present, as the bucket wheel excavator design, manufacturing level and the use of experience continue to improve, the structure of the bucket wheel excavator has also been improved.

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

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
