After many projects practice, the intelligent lubricating system of bucket wheel stacker reclaimer has reliable operating and good lubricating effect.For each lubricating point, the related people lubricate according to the demands. There will be no grease waste and lacking of lubrication. The consumption of grease is greatly decreased compared with the traditional lubrication. In this way, the surrounding environment will be kept clean, reducing the environment pollution. The good lubrication could reduce the rate of breakdown and increase the working efficiency of stacker reclaimer. The oil mass could be set and adjusted in distance. As a result, the workers could save the time of checking equipment.  In conclusion, the intelligent lubricating system of bucket wheel stacker reclaimer has following advantages: 1.Each point breakdown is clear, which make the maintenance easy.  2.Each point of lubrication system separately sets the cycle time and oil supply. The ope...

The main faults of reclaimer focus on the bucket-wheel and running mechanism. The bucket-wheel component of each reclaimer includes reclaiming hopper, wheel body, rollaway nest, chain wheel, tension device, actuating device, supporting roll, side roll, supporting wheel of trolley. The main fault form is the sharp wear of supporting wheel and supporting roll. The reasons and solutions are as follows: The water content of materials is large. The freezing of base and material pile would result in the rapid change of materials. The solution is making the reasonable proportion to the dry and wet materials, reducing the freezing of materials base.  If the clearance adjustment check is not done timely, the interval will be over the standard.  The solution is measuring the interval in regular time. If there is something wrong, we should arrange the related persons to make adjustment or make replacement.  The rollaway nest surface evenness of wheel body exceeds the standa...

According to main engine and process requirements, the controlling system of reclaimer employs three control modes including automatic, manual, and maintenance control modes. Automatic control mode: When reclaimer is prepared, the automatic control will be executed after central control room sends stop instruction. In the state of automatic control, starting sequence is according to the requirements of reclaimer equipment and the reclaimer will come into the state of automatic reclaiming. Then the automatic monitoring, giving an alarm, and auto stop instruction for the system failure could be finished. Manual control mode: Manual control processes on the operating table. It is suitable for debugging process, moving from one pile to another pile and arranging the machine assigning location to reclaim materials. It could finish one-step operation of each unit. Maintenance control mode: Maintenance control mode is used in the field maintenance. However, the operating button installa...

The stacker reclaimer is a high efficient equipment for the continuous loading and unloading of large bulk materials in modern industry. 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...

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...
