1. PAINPOINT DRIVEN OPENING

Are unpredictable maintenance cycles and component failures causing unplanned downtime on your primary crusher? Do you face escalating costs from premature wear parts replacement, especially when processing abrasive or highstrength feed material? Is inconsistent product gradation from your crushing stage creating bottlenecks and inefficiencies further down your processing line? These operational challenges directly impact your bottom line through lost production, higher consumable costs, and reduced plant availability. How can you achieve reliable, highvolume reduction with greater control over operating costs and final product specification? The solution requires a fundamental shift in equipment design philosophy focused on durability, precision, and measurable return on investment.

2. PRODUCT OVERVIEW

The Nordberg® C Series Jaw Crusher represents the industry benchmark for heavyduty primary crushing stations. Engineered for the most demanding quarrying, mining, and construction applications, this equipment is designed to process large feed sizes with high capacity and exceptional reliability. The operational workflow is centered on a robust, fixed jaw die and an aggressively angled moving jaw that creates a powerful compressive crushing action. Key steps include: 1) Large feed material enters the deep crushing chamber; 2) Material is compressed between the fixed and moving jaw dies; 3) The crushed material discharges at the bottom under gravity, with size determined by the closedside setting (CSS). This equipment is optimal for stationary primary crushing of hard rock (granite, basalt) and recycled concrete. Its limitations include being less suitable for sticky or plastic materials better handled by impact or gyratory crushers in certain configurations.

6. APPLICATION SCENARIOS

Granite Quarry Primary Crushing Station

Challenge: A major aggregate producer faced excessive downtime for jaw die changes every 68 weeks when processing highly abrasive granite, crippling their primary circuit availability.
Solution: Installation of a Nordberg® C150™ jaw crusher equipped with MX jaws.
Results: Achieved a documented wear life extension to 1012 weeks between changes, increasing annual crusher availability by approximately 15% and reducing annual wear parts cost per ton by an estimated 22%.

LargeScale Iron Ore Processing Plant

Challenge: Inconsistent feed size from the mine led to frequent bridging in the primary crusher chamber and unstable power draw, causing circuit upsets.
Solution: Implementation of a C200™ jaw crusher paired with an ASRi automated control system.
Results: The system automatically compensated for feed variations, maintaining optimal cavity level and power draw. This resulted in a 9% increase in average throughput tonnage and stabilized power consumption across shifts.
