In refractory production, the breakage rate of magnesium‑carbon bricks and out‑of‑spec products represent a long‑term cost burden for manufacturers. Traditional waste handling methods are inefficient, generate significant dust, and struggle to ensure the particle size uniformity of recycled raw materials, directly affecting the quality of new bricks. The Sihyde automatic magnesium‑carbon brick crushing line is specifically designed for the efficient recovery and reuse of waste magnesium‑carbon bricks. Centred on a closed‑loop crushing system, the line integrates intelligent control, precise screening, and environmental dust removal technologies. The magnesium‑carbon brick crushing line can reprocess waste into recycled raw materials with qualified particle sizes, helping enterprises reduce raw material costs and achieve green production.
Closed‑Loop Crushing System
Closed‑loop return logic: The magnesium‑carbon brick crushing line is equipped with a dedicated return belt conveyor that automatically transports oversized particles that fail to meet specifications after the first crushing back to the crusher. This process can be repeated multiple times until the material particle size fully meets requirements.
Crusher selection: In response to the high hardness and strong wear resistance of magnesium‑carbon bricks, jaw crushers, roll crushers, or cone crushers can be flexibly selected. They deliver high crushing force, long service life of wear parts, and can stably process various hard waste materials.
Output quality assurance: The process prevents unqualified raw materials from exiting the line, ensuring an output qualification rate of ≥99%.
Precise Particle Size Control Module
Output size adjustment: The output particle size of the magnesium‑carbon brick crushing line can be customised as needed, with a conventional adjustment range of 0–5 mm or 0–10 mm.
Control method: The final product particle size is precisely controlled through the replacement of screen mesh apertures and the setting of crushing parameters.
Raw material compatibility: It fully matches the raw material requirements for regenerated magnesium‑carbon brick production.
Intelligent Automatic Control System
Fully unmanned operation: The magnesium‑carbon brick crushing line adopts a Siemens PLC control system and an industrial touch screen to achieve full‑process automation from feeding, crushing, and screening to closed‑loop return. The equipment supports one‑button start/stop and requires no manual attendance.
Real‑time monitoring and data management: The control system supports real‑time monitoring and recording of operating status, fault alarms, and key process data. Operators can intuitively understand equipment conditions through the interface.
Safety interlock and authority management: A comprehensive safety interlock mechanism automatically shuts down the equipment when inspection doors are opened or abnormal conditions occur. Key closed‑loop crushing parameters and particle size settings require dedicated personnel authority verification.
Environmental Sealing and Modular Design
Dust‑free working environment: The magnesium‑carbon brick crushing line adopts a fully enclosed design throughout the process, complemented by a dedicated negative‑pressure dust removal system and dust collection device, effectively suppressing dust dispersion from crushing, screening, and conveying stages.
Compact and flexible structural layout: A modular design is adopted, allowing functional units to be flexibly combined and customised according to the customer's plant area, capacity requirements, and raw material storage locations.
Convenient maintenance and replacement: The modular structure facilitates individual maintenance or replacement of crusher wear parts, screens, belts, and other consumables, reducing downtime.
