1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate production margins? For plant managers and procurement specialists, selecting the right primary crushing equipment is a critical capital decision with decadelong implications. Common challenges include:
Unscheduled Downtime: Frequent mechanical failures and liner changes halting your entire processing line, costing thousands per hour in lost production.
Inconsistent Output & Product Shape: Poorly graded final product with excessive flaky material, leading to rejections from highspecification asphalt and concrete clients.
Excessive Energy Consumption: Older or inefficient jaw crusher designs consuming disproportionate power per ton of processed material, directly impacting operational expenditure.
High Maintenance Complexity: Laborintensive adjustment procedures and component replacement that requires specialized skills and extends service windows.
Rapid Wear Part Degradation: Premature failure of jaw plates and toggle systems in abrasive feed conditions, driving up your costperton for consumables.

Is your current primary crushing solution equipped to deliver the reliability, product quality, and cost control required in today's competitive market?

2. PRODUCT OVERVIEW

The modern heavyduty jaw crusher serves as the cornerstone of stationary and mobile primary crushing circuits. Engineered for the initial reduction of large quarried rock, demolition concrete, and mineral ore, this machine transforms feed material up to 1.5 meters in size into manageable aggregate for secondary processing.

Operational Workflow:
1. Feed Intake: Large dump trucks or loaders deposit runofquarry material into the vibratory grizzly feeder, which bypasses subsize material to a side conveyor.
2. Primary Reduction: The remaining oversize rock is directed into the crushing chamber, where a fixed jaw and a reciprocating moving jaw exert immense compressive force.
3. Discharge & Regulation: Crushed material exits through an adjustable discharge opening at the bottom. The CSS (Closed Side Setting) is hydraulically adjustable for precise control over final product size without stopping the machine.

Application Scope: Ideal for hightonnage primary crushing of granite, basalt, river gravel, and recycled construction materials. It is the preferred first stage in most hard rock aggregate production.

Limitations: Not suitable for sticky or clayheavy materials without prescreening. Performance on highly abrasive silicarich ores requires specific metallurgical choices in wear parts.

6. APPLICATION SCENARIOS

Granite Quarry Primary Crushing Station

Challenge: A largescale quarry operation faced declining product yield due to premature wear on their existing jaw crusher's liners when processing highly abrasive granite. Unscheduled maintenance was causing over 100 hours of annual downtime.
Solution: Implementation of our heavyduty jaw crusher featuring an optimized kinematics package and M3 grade manganese jaws specifically selected for abrasion resistance.
Results: Achieved a documented increase in wear part life by 35%, reducing annual liner changeouts from four to three. Combined with faster hydraulic adjustments, this contributed to an estimated recovery of over 60 hours of productive time annually.

Urban Recycling & C&D Processing Plant

Challenge: Processing mixed demolition concrete with sporadic metal contamination led to frequent stall events and potential damage on the primary crusher’s toggle system.
Solution: Installation of our jaw crusher equipped with the integrated hydraulic toggle relief system designed to automatically cycle when uncrushable material is encountered.
Results: The system successfully protected the crusher from damage during multiple tramp metal events per month without operator intervention. This eliminated associated repair costs averaging $15k per incident and prevented secondary downtime across the plant.
