1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate production margins? For plant managers and engineering contractors, the core challenges in primary crushing often include:
High Maintenance Costs: Frequent bearing failures, wear part replacement, and unplanned mechanical repairs directly impact your bottom line.
Inconsistent Throughput: Feed variability leads to choking or idling, preventing your plant from achieving its designed capacity and disrupting downstream processes.
Excessive Energy Consumption: Inefficient crushing chambers and drives result in high power costs per ton of processed material.
Rapid Wear Part Degradation: Improper compression or excessive abrasion shortens the life of mantles, concaves, and jaw plates, increasing both part costs and labor for changes.
Limited Application Flexibility: A single machine often struggles with varied feed materials, from hard abrasive granite to recycled concrete, forcing compromise on settings or output quality.

Is your current primary crusher a constant source of cost and complexity? What if a machine could address these pain points through robust engineering focused on total cost of ownership?

2. PRODUCT OVERVIEW

The Nordberg C Series Jaw Crusher represents the established standard for stationary primary crushing in demanding mining, quarrying, and construction applications. This heavyduty jaw crusher is engineered for longterm operation as the first stage in a multistage reduction circuit.

Operational Workflow:
1. Feed Intake: Large feed material (up to 8090% of crusher feed opening) is deposited into the deep, nonchoking crushing chamber from a loader or dump truck.
2. Compressive Crushing: A steep nip angle and an aggressive elliptical stroke motion ensure material is gripped immediately and crushed efficiently in a single pass.
3. Discharge & Setting Control: Crushed product exits at the bottom of the chamber. The discharge opening (CSS) is easily adjusted via a hydraulic wedge system for precise control over final product size.

Application Scope: Ideal for highcapacity primary crushing of hard, abrasive rock types (granite, basalt), gravel, and demolition concrete. It serves as the reliable workhorse for largescale aggregate production and mining operations.

Limitations: Not designed for ultrafine grinding or as a standalone solution for finished product shaping. Requires stable foundational support and appropriate feeding equipment to realize its full capacity potential.

6. APPLICATION SCENARIOS

Granite Quarry Primary Crushing Plant

Challenge: A largescale aggregate producer faced excessive downtime due to premature bearing failures in their primary crusher during highseason operation processing extremely hard granite.
Solution: Replacement with a Nordberg C150 jaw crusher featuring oversized spherical roller bearings designed specifically for high load capacity.
Results: Field data shows bearing service intervals extended by over 40%, contributing to a documented plant availability increase of over 300 hours annually while maintaining a consistent throughput of 550 Mtph.

Urban Construction & Demolition Waste Recycling

Challenge: A contractor needed a primary crusher capable of handling highly variable feed—from reinforced concrete to asphalt—without frequent blockages or damage from tramp metal.
Solution: Installation of a Nordberg C120 jaw crusher equipped with an automatic lubrication system and a bolted frame suitable for semimobile skid mounting.
Results: The unit achieved reliable processing of over 350 tons per hour of mixed CD waste. The hydraulic setting adjustment allowed quick changes between concrete rubble cleanup jobs (<100mm product) and larger base course production (<150mm product).
