Some Matters Needing Attention When Using Screw Feeder

During the using of screw conveyor, some faults would occur. The fault analysis and related solutions are as follows:
Feed Blocking:
1. The technical parameters of screw conveyor should be selected logically. For example, the rotating speed of screw conveyor should not be large.
2. The operators should execute the operating instruction, guaranteeing the no-load starting and parking with no-load. In this way, the materials could be entered continuously.
3. The discharge hole should be enlarged to solve the feeding block.
4. The cleaning should be carried out in period, preventing the large materials entering into the machine.
5. The hanger bearing's lateral dimension should be reduced to prevent the feeding block.
6. The silometer and blocking inductor should be installed to realize the automatic control and alarm.
7. The anti-blocking valve should be set in delivery end. When the materials are blocked, the valve could help to solve this problem.
The Burn of The Driving Motor
The hard materials enter into the screw conveyor, which stick the rimer. In this way, the electric current becomes large to burn out the motor. The solution is that we should keep certain interval between rimer and enclosure.
The waggle of enclosure
The decentraction of center lines of spiral segments makes the waggle of enclosure. We should install the screw conveyor again to find the right center line.
The high temperature of hanger bearing
The improper assembly makes the high temperature. We should install the bearing in the right place.
In general, most EPC companies would choose apron feeder, stacker reclaimer, stone crusher, pipe conveyor, screw conveyor to complete the transportation 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
