Overpile Stacker Reclaimer

The Overpile stacker reclaimer introduction:

The Overpile stacker reclaimer is a new type of indoor storage equipment based on the increasing requirements of environmental protection and land saving. This kind of product is arranged in the closed workshop, which solves the problems of material loss and dispersion in the process of stacking and material pile affected by wind and rain. By setting the surrounding retaining wall, the problem of storing more materials in smaller space is solved.            This kind of equipment adopts the conical shell stacking process and side scraper partition layer reclaiming process for stacking operation, which is widely used in various raw material storage yards with low homogenization requirements.

Working principle of Overpile stacker reclaimer:

The stacker and Reclaimer can rotate around the central column at the same time or separately to complete the stacking and reclaiming operations.            

When stacking, the stacker will transfer the materials from the trestle belt conveyor on the top of the stacker to the cantilever belt conveyor through the hopper, and implement fixed-point stacking in the yard. When the stack reaches the set height, the stacker will rotate 3 degrees to continue stacking, and so on until the yard is full.

Features of overpile stacker reclaimer:

(1) The strong structure could assure the greater durability of the stacker and reclaimer.

(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)SinomaLY 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.

The Overpile stacker reclaimer control mode: 

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.
