What Reasons Result In The Tapebreak Of Belt Conveyor?

The belt conveyor is widely used to transport the loose materials because of large delivery capacity, simple structure, low cost, easy maintenance and other features. Especially in mining, the belt conveyor has wide application. If the conveyor belt break, the belt will slide for many miles, which would break up the idler, pipe, rack cable, and small parts. If serious, the belt and materials will form bulk deposition, which would result in the halt production. The reasons of belt break are as follows:
1. The gear reducer is damaged. The fluid coupling has hydrojet phenomenon. The changeover of electromotor is also one of the reasons.
2. The conveyor belt joint has something wrong. The conveyor belt joint is divided into mechanical splice and vulcanized joint. The quality of mechanical splice is worse than that of vulcanized joint. So the application ration of mechanical splice is small. For the vulcanized joint, if the vulcanizing temperature and sulfide stress are not controlled accordingly, the quality is also bad. 
3. If the other things enter during the transportation, the transportation load will become large.
4. The variation of stresses becomes large when starting and stopping the equipment, which also will lead to the break of the belt. We should start the belt conveyor in the conditions of no load. 
5. The self quality of belt is not good. The service life of belt is too long. 
6. The materials allocation is uneven, which would lead to the off tracking of belt. 
In order to avoid the belt break, the protecting device should be set. Besides, we should also check the related equipment such as stacker reclaimer, stone crusher, apron feeder, screw conveyor, pipe conveyor to ensure the normal production.

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
