1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate production margins? For plant managers and procurement specialists, the core challenges in primary crushing often manifest in three critical areas:

Unscheduled Downtime: Bearing failures or component wear in your primary crusher can halt your entire processing line, costing thousands per hour in lost production and idle labor.
Rising Maintenance Costs: Are you constantly budgeting for highwear part replacements and reactive repairs, struggling to forecast your true cost per ton?
Inconsistent Feed & Output: Do fluctuations in feed size or material hardness create bottlenecks, leading to suboptimal throughput and uneven product gradation?

The central question becomes: how do you secure a primary crushing solution that delivers not just raw power, but predictable performance and controlled operational expense?

2. PRODUCT OVERVIEW

The Nordberg C150 Jaw Crusher is a heavyduty, singletoggle primary crusher engineered for the most demanding mining and quarry applications. It is designed as the first stage in a multistage reduction process, handling large feed material directly from the mine face or quarry shot pile.

Operational Workflow:
1. Feed Intake: Large blasted rock (up to 40”/1000mm) is loaded into the vibrating grizzly feeder (optional), which bypasses fines to increase primary capacity.
2. Primary Crushing: Material enters the deep, nonchoking crushing chamber. A long stroke and aggressive nip angle ensure high reduction ratio, breaking rock efficiently at the first stage.
3. Discharge & Conveyance: Crushed product is discharged at the bottom of the chamber onto a main conveyor belt for transport to secondary crushing or stockpiling.

Application Scope: Ideal for stationary primary crushing plants in hard rock mining, granite/basalt quarries, and largescale industrial mineral operations.
Limitations: Not designed as a standalone finished product solution; requires secondary/tertiary stages for most aggregate specifications. Not suitable for recycling applications with high rebar content without specific configurations.
