How to solve the off tracking problem of belt conveyor?

The off tracking of belt conveyor is the common problem in the production. Especially, belt conveyor installed in inclined drift is easy to have off tracking of belt. If this problem could not be solved timely, the coal production will be limited and the equipment performance will be worse, which would reduce the service life of belt and many result in accident.
If the off tracking of belt occur, we should confirm the reason and then solve it accordingly. We should deal with it according to actual conditions to guarantee the normal operation of the belt conveyor.
If the upper belt has deviation in one direction and the lower belt has deviation in the other direction, this could result from the large diagonal deviation. We could adjust the frame to higher place, making upper and lower idlers bear large load. There is no off tracking with load, while off tracking occurs without load. This situation is common where it is downhill and hanging segment. At this moment, the belt is controlled by several idlers. In the summon, the idler has large acting force to the belt. When adjusting this problem, the belt will be instable. When the belt conveyor operates without load, the belt and idler have no strict touch, which result in the situation that thrust force could not reach the belt. The solution is as follows:
If possible, the tensity of belt could be reduce accordingly and the frame could be lifted. Also the vertical idler could be installed to adjust the off tracking of the belt. When fixing the idler, it will be better if the idler could rotate with the belt. In this way, the purpose of adjusting off tracking could be realized, which reduces the abrasion to the belt edge.
Besides, the conveyor components play an important role. Most EPC companies would purchase the suitable belt and related conveyor components to coordinate the operation of apron feeder.

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
