Slag Crushing System for Desulfurization Slag Treatment

Product Specifications

Technical details and manufacturing context for Slag Crushing System

Definition

The Slag Crushing System is a component within an integrated hot metal desulfurization and slag treatment system. Its primary function is to receive solidified or semi-solidified slag from the desulfurization process and mechanically break it down into smaller, uniform particles. This size reduction facilitates efficient cooling, handling, transportation, and potential material recovery, such as metal reclamation or use as aggregate, thereby completing the slag treatment cycle and minimizing waste volume. The system typically employs crushers such as jaw crushers, impact crushers, or roll crushers to apply compressive or impact forces onto the incoming slag. Large chunks are fed into the crusher's chamber, where moving mechanical parts fracture the material against fixed surfaces or other moving parts. The crushed slag is discharged at a predetermined size, often controlled by adjustable gaps or grates. Key parameters include a crushing capacity of 5–20 t/h, feed size up to 300 mm, discharge size up to 25 mm, crushing ratio of 6–12, motor power of 15–45 kW, operating voltage of 380–690 V (IEC 60038), operating temperature of -20 to 50 °C, ingress protection of IP54–IP65 (IEC 60529), noise level up to 85 dB(A) at 1 m (ISO 3744), weight of 2–8 t, and dimensions varying by model. Materials used include high-chromium cast iron and manganese steel. These values are reference ranges and must be verified for the specific model and application. The system is designed for basic metal manufacturing environments. For procurement, confirm model-specific specifications and applicable standards with the legal manufacturer or supplier.

Working Principle

The system uses mechanical crushers, such as jaw, impact, or roll crushers, to apply compressive or impact forces to slag. Large slag chunks are fed into the crushing chamber, where moving parts fracture the material against fixed surfaces or other moving parts. The crushed slag exits at a controlled size, typically set by adjustable gaps or grates. The process reduces slag volume and prepares it for further treatment or disposal.

Frequently Asked Questions

What is the typical crushing capacity of this system?

The reference range is 5–20 t/h, depending on slag hardness and feed size. Confirm the exact capacity for your specific model and application with the manufacturer.

What materials are used in the crusher components?

High-chromium cast iron and manganese steel are listed as materials on file. These are common wear-resistant materials, but verify the actual materials for your unit.

What standards apply to the electrical and noise specifications?

Operating voltage references IEC 60038, ingress protection references IEC 60529, and noise level references ISO 3744. These are reference standards; confirm compliance for your specific model.

How is the discharge size controlled?

Discharge size is adjustable via crusher settings, such as gaps or grates, and is typically up to 25 mm. The exact adjustment mechanism depends on the crusher type.
