1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Managing bulk slag is a critical yet costly bottleneck in metal production and aggregate processing. Inefficient handling directly impacts your bottom line through excessive downtime, coûts d'entretien élevés, and lost revenue from unrecovered material. Êtes-vous confronté à ces défis persistants?

High Downtime for Primary Crushing: Frequent clogging and bridging in the crusher feed hopper halt your entire processing line, leading to hours of unplanned stoppages and lost throughput.
Usure excessive & Coûts d'entretien: La nature abrasive des scories dégrade rapidement les composants standard du concasseur.. The constant cycle of part replacement and labor for maintenance creates unpredictable operational expenses.
Réduction de taille inefficace & Uncontrolled Output: Inconsistent feed or unsuitable crushing chambers produce offspec material—either too large for downstream conveyors or too fine, creating dust and reducing the value of your end product.
Low Throughput Capacity: An underpowered or incorrectly specified crusher becomes the choke point of your plant, preventing you from scaling operations to meet demand and clear stockpiles efficiently.
High Operational Labor Requirements: Manual intervention for clearing blockages, monitoring feed, and adjusting settings increases labor costs and safety risks.

If these issues sound familiar, your operation requires a purposeengineered solution designed specifically for the demands of bulk slag reduction.

2. APERÇU DU PRODUIT

A Bulk Slag Crusher Plant is a stationary or semimobile integrated system engineered for the primary and secondary reduction of large, abrasive slag materials from blast furnaces, aciéries, or nonferrous metal production. It transforms irregular slag boulders into a controlled, sized aggregate for recycling as construction material, rail ballast, or feedstock for further processing.

Flux de travail opérationnel:
1. Alimentation & Présélection: Bulk slag is loaded into a robust vibrating grizzly feeder, which removes fine fractions (50mm) prior to crushing, increasing overall plant efficiency.
2. Réduction de la taille primaire: Oversize material is conveyed to a heavyduty jaw crusher or primary impactor designed to accept large feed sizes (jusqu'à 1200 mm) and break them down to manageable dimensions (150250mm).
3. Concassage secondaire & Dimensionnement: The primary crushed material is then processed by a secondary cone crusher or impact crusher configured for high abrasion resistance, producing precisely graded final products (par ex., 05mm, 520mm, 2040mm).
4. Material Sorting & Stockage: Crushed material is sorted via vibrating screens; onspec product is conveyed to stockpiles while oversize material is recirculated back to the secondary crusher.

Champ d'application: Idéal pour les aciéries intégrées, chantiers de traitement de scories autonomes, mining operations with byproduct slag, and aggregate producers specializing in industrial byproducts.

Limites: Non conçu pour être mouillé, sticky materials without prior drying; maximum feed size and hardness are constrained by the modelspecific design of the primary crusher.
