Circular Stacker Reclaimer

Brief introduction of circular stacker reclaimer：

The circular bridge scraper adopts the stacking and reclaiming technology of continuous herringbone stacking and full section reclaiming. The stacking layer number of the equipment can reach more than 500, and the homogenization coefficient is more than 10. It is the best mixing equipment in the stacker reclaimer. It is mainly used for stacking limestone, coal and other bulk materials. This kind of equipment realizes the whole machine unmanned operation and the integration of machine, electricity and hydraulic. It has the characteristics of good homogenization effect, large stock yard reserves, small floor area and high degree of automation. It is the most advanced large-scale mixing process equipment in China at present. Its technical characteristics, stockyard parameters and automation level are first-class in China.

Working principle of circular stacker reclaimer:

This machine adopts continuous herringbone stacking and full section reclaiming. Under the PC program control, the stacker arm rotates to and fro. At the same time, it completes the periodic variable amplitude and variable speed movement from rising to falling in the process of one reciprocating rotation, which makes the stacking trajectory curve appear parabolic. Continuous herringbone stacking process is realized.

The reclaimer runs around the center pillar in the circular material yard through the end beam, and the rake moves back and forth along the bridge to realize the full section reclaiming. Finally, the material is scraped to the bottom of the center pillar through the scraper conveying system and transported out by the pit belt conveyor.

Features of circular stacker reclaimer: 

1. To adapt to the requirements of the stacker and reclaimer for greater durability;

2. The bulk material handling equipment is equipped with a variety of control methods to ensure flexible handling of bulk materials in different situations;

3. Through simple installation and simple training process, a single employee can easily operate the equipment;

4. Can adapt to the requirements of different yards, customized products for customers.

5. Sinomary has steel pretreatment production line, which can improve the corrosion resistance of structural parts and ensure the quality of all finished products. The use of large milling machine improves the machining accuracy of large parts. In the factory, the structure is assembled as a whole and the drive system is debugged.

6. SinomaLY uses high-performance new materials, such as wear-resistant materials and composites, to improve the durability of bulk material handling equipment.

7. Soft start and frequency conversion control are adopted to reduce the damage of stacker reclaimer caused by severe impact. Protective measures are set on the equipment, which can be adjusted or stopped automatically in case of abnormal conditions.

Control mode of circular stacker reclaimer:            

The stacker reclaimer is equipped with three operation modes: automatic control, manual control and machine side (maintenance) control. The three operation modes are interlocked, that is, one of the operation modes is selected, and the other two operation modes are invalid.            

1. Manual control

The manual control on the machine is applicable to the working conditions required in the debugging process and the working conditions when the automatic control fails, the stacker and Reclaimer are required to continue to work, and it is allowed to stack and reclaim according to the non specified stacking mode. The operator controls the corresponding buttons on the operation panel in the on-board control room for manual stacking and reclaiming.           

2. Automatic control

The stacking and reclaiming operation under the automatic control mode can be implemented by the central control room and the onboard control room. When the central control room is required to automatically control the stacker reclaimer, the operator only needs to press the automatic operation button on the console, and then press the start button, all the electrical equipment on the stacker reclaimer will start according to the predetermined procedure, and the whole machine will be put into normal automatic operation. On the console of the central control room, the stacker reclaimer can be started or stopped by pressing the button.           

3. Machine side (maintenance) operation  

The local control is suitable for the local action during the installation, overhaul and maintenance, which is realized by the operation button set beside the machine. In this control mode, the interlocking of the driving mechanisms of the stacker and reclaimer is released, and can only be started or stopped independently.
