1. PAINPOINT DRIVEN OPENING

Are you managing escalating operational costs and unpredictable downtime in your aggregate production? Inconsistent feed material, abrasive wear on components, and inefficient power utilization directly impact your bottom line. Consider these common challenges:
Unplanned Downtime: Frequent breakdowns due to component failure can cost over $10,000 per hour in lost production and labor.
High Wear Part Consumption: Excessive replacement of jaws, liners, and blow bars under abrasive conditions erodes profit margins.
Inefficient Energy Use: Crushers operating outside optimal parameters consume 1525% more power, a significant fixed cost.
Product Quality Inconsistency: Poorly calibrated crushing chambers yield offspec aggregate, leading to product rejection and wasted raw material.
Regulatory Compliance Risk: Operating with noncompliant components can result in fines and supply chain disruptions for your clients.

How do you select equipment that addresses these specific cost centers while ensuring reliability and compliance? The foundation lies in a robust, intelligently engineered primary crushing solution.

2. PRODUCT OVERVIEW

The Rohs Compliant Stone Crusher Machine is a heavyduty primary jaw crusher engineered for the initial reduction of hard, abrasive quarry rock (e.g., granite, basalt) into consistent, coarse aggregate. It is designed for stationary plant installation or robust mobile setups.

Operational Workflow:
1. Feed Intake: Large raw quarry stone (up to specified feed size) is loaded into the vibrating grizzly feeder (optional), which bypasses fines to optimize chamber loading.
2. Primary Crushing: Material enters the fixed and moving jaw assembly. The mechanically actuated moving jaw compresses rock against the stationary jaw, applying immense pressure to fracture it.
3. Discharge & Sizing: Crushed material exits through the bottom discharge opening (CSS Closed Side Setting), determining the primary product size. This output is then conveyed for secondary processing or stockpiling.

Application Scope: Ideal for primary crushing in quarrying, mining, and largescale construction waste recycling operations. Best suited for materials with compressive strength below 320 MPa.

Limitations: Not designed as a finished aggregate producer; secondary or tertiary crushers are required for final sizing. Performance is contingent on proper feed sizing and material characteristics.
