The control mode and maintenance of reclaimer

According to main engine and process requirements, the controlling system of reclaimer employs three control modes including automatic, manual, and maintenance control modes.
Automatic control mode:
When reclaimer is prepared, the automatic control will be executed after central control room sends stop instruction. In the state of automatic control, starting sequence is according to the requirements of reclaimer equipment and the reclaimer will come into the state of automatic reclaiming. Then the automatic monitoring, giving an alarm, and auto stop instruction for the system failure could be finished.
Manual control mode:
Manual control processes on the operating table. It is suitable for debugging process, moving from one pile to another pile and arranging the machine assigning location to reclaim materials. It could finish one-step operation of each unit.
Maintenance control mode:
Maintenance control mode is used in the field maintenance. However, the operating button installation is beneficial to maintenance operating position, so it is only suitable for field maintenance. To protect the hardware equipment reliability, programmable controller, frequency changer, intelligent motor controller and other main components and parts matched with stacker-reclaimer are the products from ABB company. The material level examining device of stacker-reclaimer is original products from German company.

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
