A Circular stacker-reclaimer is mainly composed of the stacker and the reclaimer. The stacker mainly consists of the cantilever stacker belt conveyor, the central column rotary mechanism, the hydraulic luffing mechanism, etc.; while the reclaimer includes such components as the bridge, the scraper conveying system, the rake system, the end beam traveling mechanism and the electric control system, etc.
This stacker and reclaimer is a new model developed to meet the demands for high material density, rigid environmental requirements and high explosion-proof grade. The steel structure is optimized with finite element analysis, and PLC is used as the control unit for all components of the electrical control system. Variable-frequency motors are widely used in the electrical systems of slewing drive and traveling drive to further stabilize operation of the equipment.
Explosion-proof requirement is common for the equipment operating in the closed stockyard. such as motor, brake, rubber belt, switch etc. to be explosion-proof, and the operator's cabin is also a confined explosion-proof system with positive pressure. Meanwhile, we provide a manual or automatic fire fighting system, which can be installed in the center of stacker and reclaimer as requested by the client. On the top of the stacker and reclaimer , a 4-in-1 (methane, CO, H2 and temperature) monitoring is provided system, which performs ongoing monitoring of the gases in the stock yard to prevent gas explosion. The newly designed stacker and reclaimer ensures equipment protection and operator's safety at the same time, making it critical in the operation.
Mainly applied in stacking/reclaiming coal in stock yards as one of the most important devices in the production system of power plants, coal mines, metallurgy works and chemical works.
