As we all know, the bucket wheel stacker reclaimer 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 degrees, while the portal bucket wheel stacker reclaimer could not do that. The advantage of portal bucket wheel stacker reclaimer is average reclaiming and stable productivity. The reclaiming quantity of boom bucket wheel stacker reclaimer is varying, and the productivity is also varying, which is called the crescent moon loss. In most conditions, the stacker reclaimer coordinates with belt conveyor to complete the handling process of materials. So a good belt conveyor design and conveyor components could reach the best performance of whole handling system.

The stacker reclaimer is widely used to handle materials. The reclaimer coordinates with stacker to handle materials in blending stockyard. The stacker stack the materials and then the materials stacked reclaimed by reclaimer on the other side. Then the materials are transported to the belt conveyor through feed channel. Every time the reclaiming boom handle one layer of materials, it would descend to fixed height according to the scheduled instruction. In fixed operating speed, each layer of materials should be handled step by step until all the materials are reclaimed completely. This reclaiming process make the materials handled evenly. When reclaiming the materials, the reclaimer would be adjusted to the fixed stock bin. The series number of stock bin could be identified through the travelling and inhibiting device. The reclaimer would be limited in limiting position in the stock bin, doing reciprocating motion of reclaiming materials according to the process. The encoder installed in electric block could control the descent angle of the scraper blade, ensuring the constant relaiming capacity. Under the conditions of fixed constant reclaiming capacity and reclaiming speed, the descent angle of boom and scraper blade is decreased step by step. In this way, the layer-by-layer reclaiming of materials could be realized. The operating speed of reclaimer could be adjusted through drive motor, which determines the reclaiming quantity of the reclaimer.
In most conditions, the reclaimer coordinates with the pipe conveyor, apron feeder to complete the handling of materials. The apron feeder is the auxiliary equipment of transportation machinery. The apron feeder is widely used in cement, building materials and other fields. The conveyor components of apron feeder are so important when the apron feeder operates.
Installation: The apron feeder could be installed partially and integrally. For the partial installation, the connecting section is installed in hatch opening, and then the feed channel is installed. The transmission chassis and other parts are installed finally. For the integral installation, the connecting section is installed in coal bunker and then other parts are assembled. The integral hoisting and connecting piece are connected by bolts. Debugging: The feeding gate is closed with adding lubricating grease in turning part. The oil is injected into the gearbox with 90% of the box. If everything is complete and no other sundries are in the equipment, the professional operator starts the motor in safe conditions. After operating with non-load for 30 minutes and all the parts in good conditions, the equipment could be put into normal use. The feeding amount is determined by the operating speed of apron feeder. In the normal operation, the regular check and maintenance should be carried out about the wearing conditions of parts, especially for conveyor components. About the belt conveyor design, it will be referred to in following blog. The pipe conveyor is developed from the normal materials handling form, which is widely popular among many users. In most projects, the pipe conveyor is used as the mining equipment to coordinate with the apron feeder to handle materials. At present, the pipe conveyor is said to the best solution of handling materials.
The pipe conveyor should have rigidity, which could stay tube shape when passing the idler sets. At the same time, there should be flexibility of pipe conveyor, which could guarantee that the belt could pass the transition section. In order to guarantee the rigidity and flexibility of the belt, a special skeleton structure should be adopted. In order to the good sealing of the overlapping part and prevention of material leakage, the rigidity of belt edge should be reduced. The thickness of top and bottom glue lines should be controlled to increase the ability of belt changing to the pipe shape. In emergency maintenance, the metal connection or normal belt could replace the pipe belt until to the long-term upkeep. The normal conveyor belt doesn't have rigidity and flexibility, which would result in tiredness and other uncertain problems. However, the normal conveyor belt has advantages of simple structure and low cost. For the service life, the normal conveyor belt has the same service life as the pipe conveyor belt. For the cleaning device, they also have the same application of revolving brush and nonloaded cleanser. Among most mining equipment, the apron feeder, stacker reclaimer, belt conveyor are used to handle materials. And for the components, the operator should pay attention to the maintenance of the conveyor components. The apron feeder is the auxiliary equipment of transportation machinery. The apron feeder is mainly used in mammoth mill, cement, building materials and etc. The apron feeder could be used as stock bin to feed materials to primary breaker. The safe operation rules of apron feeder are as follows:
1. Before starting the apron feeder, some sundries such as iron should be checked to avoid the apron feeder of getting stuck by these sundries. 2. Some crushed aggregates should be placed in stock bin before starting without load. 3. Some related person should check whether there is crack in scraping belt and there is looseness of connecting screw. 4. After starting the apron feeder, the operator should pay attention to the speed of the mineral. If the bigger ores appear, the operator should stop the equipment avoiding the blocking of the mouth. 5. After receiving the stop signal, the transporting of materials should be stopped until the feeding signal comes. 6. The lubricant passage way should be checked carefully to find out the break and crack condition of pipeline. 7. The motor and drive bearing should be checked in regular period. And after starting the motor, the operator should listen to the sound of motor to check whether there is abnormal occurrence. The Analysis Of Advantages And Disadvantages On Boom And Portal Bucket Wheel Stacker Reclaimer1/4/2017 As we all know, the stacker reclaimer coordinates with belt conveyor and screw 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 degrees, while the portal bucket wheel stacker reclaimer could not do that. The advantage of portal bucket wheel stacker reclaimer is average reclaiming and stable productivity. The reclaiming quantity of boom bucket wheel stacker reclaimer is varying, and the productivity is also varying, which is called the crescent moon loss. As we all know, the pipe conveyor, as one of the mining equipment, is common when handling materials. In order to avoid the lock of conveyor belt by structure frame, the conveyor belt should be adjusted in regular. And this also shows the importance of better belt conveyor design. When the operator starts to check the conveyor belt, it is important to start the belt conveyor after all the related parts are examined. If the belt conveyor is operating with no load, some related person should be sent out to monitor the belt conveyor along the overall length.
The adjustment of belt should be processed alone, which could save the working task of adjusting the idlers. The adjusting work should be from pulley, feeding part, bearing part in the end of conveyor to the head of conveyor, making the belt smoothly pass the driving pulley and then back to the pulley in the end. In order to adjust the conveyor belt, two twist correction idlers are set in bearing part and returning part. Before adjusting the conveyor belt, the overlapping part should be checked first to confirm whether it is clockwise or anticlockwise. After that, the location of idler could be confirmed with mark for reference. In the course of adjustment, the belt conveyor should be operated with half load and then full load to test. And all the idler frames adjusted should be fastened again. At the same time, the maintenance of the conveyor components is also important, which could prolong the service life of the conveyor belt. |
