The key equipment in the aluminum electrolysis anode assembly workshop is used to press‑off and remove residual carbon blocks from the spent anode busbar assemblies. Depending on the varying thickness of the residual carbon blocks on site, residual‑carbon removal presses are primarily categorized into bottom‑pull type, shear‑type, and top‑push type machines.

Specialized equipment for the anode assembly workshop
The Loading and Unloading Station primarily handles the loading of electrolyte‑containing rod assemblies and the unloading of new anode carbon blocks. It consists mainly of a pallet‑carrying trolley, a discharge chute, beam columns, a positioning device, lateral and longitudinal centering mechanisms for the rods, a bell‑cover opening mechanism, and traveling rails. The main workstations include the loading station (initial position), the unloading station, the flipping station, the electrolyte‑unloading station (for trailers), and the new anode carbon block‑loading station (for trailers). The system’s control comprises a pneumatic system and a PLC system with a human–machine interface.
The electrolyte automatic cleaning machine is a large-scale electrolyte‑removal system designed to thoroughly clean the electrolyte adhering to spent anodes. The automated electrolyte‑cleaning process is complex and challenging; after years of research and practical application, our company has successfully developed this machine by drawing on the strengths of foreign equipment and adapting it to domestic conditions.
The residual‑anode shot blasting machine is primarily used to remove the loose, high‑sodium carbon layer from the surface of steel‑claw residual anodes. The equipment can be operated manually or connected to a site‑based PLC for automated production. The system comprises a blasting unit, a shot‑media leakage prevention device, a purging unit, a screw conveyor, a bucket elevator, a separation unit, a shot‑media storage bin, a dust‑collection system, and electrical and control systems. It is complemented by a step‑type pusher cart, a rotary device, and a conveyor‑car positioning mechanism supplied by the overhead‑chain manufacturer, enabling the recycling and shot‑blasting cleaning of residual anode blocks.
The Butt Press is a key piece of equipment in the aluminum electrolysis anode assembly workshop, used to press and remove residual anode blocks from the spent anode rod assemblies. The pressed‑off rod assemblies are then reassembled with new carbon blocks for reuse, while the detached residual anode blocks fall along the discharge chute into a belt conveyor at the lower end of the machine, which transports them to the next workstation for further utilization. The operational sequence of this equipment is primarily driven by the hydraulic system and the control system.
The Thimble Press enables the thimbles on four steel claws to be simultaneously removed, preparing the anode assembly for the next process. The removal process is driven by the hydraulic system of a hydraulic workstation, which actuates the hydraulic cylinder. Each pressing cycle removes the thimbles from all four claws. The equipment can be operated manually or connected to the site’s PLC for automated production.
The Thimble Cleaning System is used to remove residual sand, oxide scale, and other impurities from the surface of thimbles. The core working components of the Thimble Cleaning System are two cleaning drums; when the equipment’s drive unit is activated, both drums operate simultaneously. The thimbles that have been pressed off are conveyed into the drums via a conveyor. During feeding, one drum is loaded first; once it is fully loaded, an electro-hydraulic pushrod actuates a flip plate to rotate, feeding material into the other drum, while the previously loaded drum begins the cleaning process and discharges the cleaned thimbles. At this point, the electro-hydraulic pushrod again actuates the flip plate to feed the first drum, by which time the second drum has already been loaded and can commence cleaning. As the drums rotate in the forward direction during the cleaning cycle, the material simultaneously undergoes axial up-and-down movement, causing continuous collisions, rubbing, and friction among the particles, thereby loosening and removing surface contaminants. The detached impurities exit through the drum’s ash‑drain holes, while the thimbles, rotated in the reverse direction, flow out through the discharge port. With both drums operating concurrently and feeding continuously, production remains uninterrupted, and the equipment automatically handles both loading and unloading.
The Stub Chain Cleaner is primarily used to remove electrolyte adhering to the steel claws. Our company’s designed and manufactured Stub Chain Cleaner employs four chain‑swinging stations to accomplish this task. Each station consists of two sets of swing chains on either side and one set in the middle, enabling all‑round chain‑swinging cleaning of the steel claws and ensuring a more thorough clean. Once cleaning is complete, the guide‑rod assembly is conveyed out of the equipment via the suspended chain, while the next guide‑rod assembly enters the subsequent work cycle.
The Stem Straightener can fully meet the production requirements of the anode assembly workshop at the carbon plant, straightening aluminum stem rods that are bent on-line from two directions—90° and 270°—at various height positions, thereby turning them into qualified aluminum stem rods for reuse. This equipment is manually controlled and features a vertical arrangement of lifting cylinders and straightening cylinders. When the overhead conveyor delivers the aluminum stem rods to the straightening position, the straightening cylinder performs the straightening operation, while the lifting cylinder adjusts the bending points of the upper and lower aluminum stem rods.
The Casting Station is used to engage the new anode carbon blocks delivered by the ground conveyor with the anode steel claws conveyed by the overhead chain conveyor. The casting machine then uses molten iron to cast the new anode carbon blocks and anode steel claws into a complete new anode assembly, which is subsequently transported out of the Casting Station by the overhead chain conveyor.
The autogenous mill is mainly used to process electrolytes from assembly workshops and all other sources. After being crushed to the required particle size by the autogenous mill, it enters the finished product warehouse and is finally transported to the electrolysis workshop as insulation material by a dedicated vehicle.
