The Matters Needing Attention Of Using Screw Conveyor

The screw conveyor is a kind of equipment which uses motor to drive the screw to rotate. The screw conveyor could transport the materials in horizontal, inclining, and vertical direction. It has many advantages such as simple structure, small cross sectional area, good sealing, easy operation, simple maintenance and etc. During the actual operating, there will be some problems. The reasons analysis of some problems are as follows:
The conveyor screw axis would stop rotating. In generally, there are three reasons.
The materials handled are too large. In this way, the materials could not get through the hanger bearing, which increases the resistance and results in the load running and machine halt. So the materials must be cleared. 
The resistance of middle bearing has large resistance. The sealing is easy to be damaged. If the materials enter into the bearing, the halting and damaging of bearing will occur. 
The bearing of reducer is damaged.
The bearing temperature of reducer will increase greatly after the equipment operates. Sometimes the abnormal noise and vibration of motor will occur. We should stop the operating quickly to check the reasons. 
The output shaft temperature of reducer is high. The input shaft's temperature is normal. This may be the reason that the center line of screw shaft has skewing. Maybe the output shaft has been burned. We should loose the coupling between output shaft and screw shaft and revise them accordingly.

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
