One reclaiming operating line with two bucket wheel stacker reclaimers is mainly used in the coal blending working in wharf, which belongs to belt conveyor mixture coal blending method. The fetching and coal blending means that the coals are stored and fetched by two reclaimers. BQ1 and BQ2 will be allocated with one reclaimer. Finally, the materials are transported to the ship loader. If the coal blending demand and reclaiming proportion is different, the reclaiming with low reclaiming proportion will have underloading situation, which results in the energy waste.  "One belt, two machines" layout could obviously avoid the light running of belt conveyor. After comparing the advantages and disadvantages of different layout, most wharfs will adopt "one belt, two machines" layout. One reclaiming operating line with two bucket wheel stacker reclaimers has been widely used in the wharfs of coal blending such as port of Qinhuangdao, port of Tianjin, port of Huanghua,...

With the economic globalization, the bulk cargo terminal plays an important role. Our company optimizes the design of bulk cargo terminal to increase the operating efficiency and reduce the cost.  The bulk cargo terminal is one important part of handling system and also the place where the materials are stored. The optimizing of the belt conveyor system could increase the flexibility of stacker reclaimer , increasing the use ratio of stock yard. In this way, the operation efficiency could be better, realizing the energy conservation and efficiency of storage yard.  According to the characteristics of bulk cargo, the loading and unloading line is divided into 3 types including stacking line, reclaiming line, and combined line. According to different processing layout, the belt conveyor system will be collocated with different handling machinery such as stacker, reclaimer, apron feeder,  pipe conveyor and etc. In generally, one belt conveyor system is arranged with...

The stacker reclaimer is a continuous bulk materials handling equipment, which is widely used in port, metallurgy, cement, steelworks, coking plant, coal factory, power station and etc. Sometimes, the stacker reclaimer coordinates the belt conveyor, apron feeder to complete the materials handling process.  The center pillar is regarded as the center of cantilever stacker. One end is steel structure belt conveyor and the other end is balance weight. The stacker is connected with rotation device, realizing the rotation through the engaging between small pinion of rotary actuator and gear ring of large bearings. The materials entering into the round yard would be unloaded to the stock ground through the head of cantilever belt conveyor. The materials probe is set in the two sides of discharge opening. If the top surface of material pile touches the probe, it shows that the material pile has reached the designed height. The pitching of hydrocylinder is adopted by stacker, whose ad...

There are many places which need the unloading of bulk materials such as specialized marine terminal, steelworks, large-scale thermal power plants, storage yard of mining. The bucket wheel stacker reclaimer is one kind of continuous conveyors. The materials could be transported according to the fixed landline with constant or variational speed. Most EPC companies would choose the bucket wheel stacker reclaimer to complete the materials transportation. In the loading and unloading operation of bulk materials, the stacker reclaimer is the main part of line production transportation. The stacker reclaimer could coordinate with other conveying equipment to make up different technological processes, meeting the different requirements of different storage yards and operation points. The apron feeder and belt conveyor are the common matching equipment. The stacker reclaimer plays an important role in bulk handling inside of ports and in materials transportation outside of ports.

Unloading of tippler-Belt conveyor system- Stacking ...

The stacker reclaimer is widely used in wharf, power plant, metallurgy and other industries. Bucket wheel stacker reclaimer's bucket would craze with high rate of wear, which reduces the service life of bucket. The cracking of bucket makes the production in passive situation. The damage of bucket has following forms: The corner where the tooth is installed cracks. This is the common fault for the damage of bucket. If the equipment continues to operate, the cracking will be more serious, which would result in the unbalance and transformation of bucket disc. The right method is to stop the operation and renew bucket. There is cracking on the chain corner. This is one of the common faults of bucket. If the stacker reclaimer continues to operate, the bucket lip cracking would occur. All we need to do is to stop the operation and renew the damage part. The teeth and lip of bucket are easy to wear. The teeth and lip of bucket are the most important parts of the bucket, which be...

Now the stacker reclaimer has been widely used in ports, docks, metallurgy, cement, coal, steel plants, coking plants, coal storage plants, power plants, coal and other fields for handling bulk materials. There are three operating methods for the stacker reclaimer. Semi-automatic operation: Before operating the stacker reclaimer , the workers would set related parameters according to the actual conditions. The related parameters include the rotating speed of stacking boom, rotation angle of stacking boom, pitching angle of stacking boom, detecting switch signal on the conditions of stacking materials. The related parameters for reclaiming materials involve in rotating speed, rotation angle, and nutation angle of scraper reclaimer, and control settings for the switch. After completing the settings of parameters, the semi-automatic operation for stack...

Bucket wheel stacker reclaimer is developed from the bucket wheel excavator, and it is a highly efficient continuous loading and unloading equipment. It is a large-scale loading and unloading equipment for bulk materials in ports, large and medium-sized thermal power plants and metallurgical enterprises. The bucket wheel of the bucket wheel stacker reclaimer is mounted on the front end of the cantilever belt conveyor and lifted up and down with the cantilever belt conveyor to accommodate the different height of the coal. When the bucket rotates to the lower part, the bucket receives the coals. The bucket wheel continues to rotate to the highest point, and the coal comes down by its own weight. The cantilever belt conveyor will conveys the coal to the center coal pipe. Then the bucket wheel completes the reclaiming process. When the material is to be stocked, the ground belt conveyor rotates in the opposite direction, during which the coal passes through the tail car. The coals are c...

The boom bucket wheel stacker reclaimer has two operation modes including stacking and reclaiming materials. The stacking materials mode is that the materials conveyed by belt conveyor are discharged by the tail car to the belt conveyor on the boom. Then the materials are discharged to the stock ground. Through the operation of the whole engine, the rotation and pitching of cantilever crane, the materials pile could form trapezoidal cross-section. The reclaiming process is realized by the rotation of cantilever crane and bucket wheel. The materials is discharged through the stripper plate to the belt conveyor on the boom, and then discharged through the funnel to the belt conveyor on the stock ground. The constituents of boom bucket wheel stacker reclaimer include bucket wheel mechanism, swing mechanism, boom belt conveyor, tripper car, pitching and running gear. bucket wheel mechanism: it is the operating mechanism of reclaiming materials including bucket wheel and related actuating...
