1. PAINPOINT DRIVEN OPENING

Managing a stone quarry crushing plant presents persistent operational and financial challenges. Are you contending with:
Excessive Downtime: Unplanned stoppages for liner changes, blockages, or mechanical failures, costing thousands per hour in lost production and idle labor.
Inconsistent Product Yield: Poorly calibrated or worn crushing stages producing offspec aggregate, reducing premium product yield and forcing recrushing.
Spiraling Maintenance Costs: Frequent replacement of highwear components like mantles, concaves, and jaw plates, coupled with high labor hours for servicing.
High Energy Intensity: Inefficient crushing chambers and drives that consume excessive power per ton of processed material, directly eroding profit margins.
Inflexible Configuration: A plant that cannot be easily adjusted to meet changing market demands for different aggregate sizes or volumes.

If these issues sound familiar, the efficiency of your entire operation hinges on the core of your process: the primary crushing station. The right ODM stone quarry crushing plant solution must address these points directly with proven engineering.

2. PRODUCT OVERVIEW

This product is a heavyduty, stationary primary jaw crusher plant, engineered as the first reduction stage in a hard rock quarry operation. It is designed to receive blasted feed from haul trucks and reduce large boulders (up to 1200mm) to manageable sizes for secondary crushing.

Operational Workflow:
1. Feed Intake: Dump trucks deposit shot rock into a rugged steel apron feeder.
2. Primary Crushing: The apron feeder conveys material at a controlled rate into the jaw crusher, where compressive force breaks the rock.
3. Primary Screening & Bypass: A grizzly section ahead of the crusher removes natural fines, while an integrated bypass chute handles oversize or uncrushable material.
4. Product Conveyance: Crushed product is discharged onto a main conveyor belt for transport to the next stage of the processing circuit.

Application Scope & Limitations:
Scope: Ideal for hightonnage production of granite, basalt, limestone, and other abrasive aggregates. Suited for permanent installation in largescale commercial quarries.
Limitations: Not designed for portable applications, very sticky or claybound materials without preprocessing, or as a standalone finishing plant without secondary/tertiary stages.

3. CORE FEATURES

Deep Crushing Chamber & Optimized Kinematics | Technical Basis: Increased nip angle and longer crushing stroke | Operational Benefit: Higher volume reduction per cycle, reducing cycle count and wear | ROI Impact: Up to 15% higher throughput capacity within the same footprint

Hydraulic Toggle & Adjustment System | Technical Basis: Replaceable hydraulic cylinder for tensioning and clearing | Operational Benefit: Enables quick clearing of tramp metal and chamber blockages in minutes vs. hours; allows safe CSS adjustment under load | ROI Impact: Reduces downtime events by an average of 80% for chamberrelated stoppages

QuarryGrade HeavyDuty Frame | Technical Basis: Fabricated steel plate design with reinforced stress points and finite element analysis (FEA) validation | Operational Benefit: Withstands continuous highimpact loading and cyclic stress without frame fatigue or cracking | ROI Impact: Eliminates risk of catastrophic frame failure, extending operational life beyond 20 years

Integrated Motor Base & Drive Guarding | Technical Basis: Unified baseplate for crusher and motor with full perimeter guarding | Operational Benefit: Simplifies alignment during installation; provides inherent safety compliance; reduces installation time by approximately 30% | ROI Impact: Lowers total installed cost and ensures immediate operational safety compliance

WedgeBased Jaw Plate Retention System | Technical Basis: Mechanical wedge lock system secures jaw plates without backing resin | Operational Benefit: Allows fast replacement of jaw liners; typically completed in under 4 hours by a standard maintenance crew | ROI Impact: Increases plant availability and reduces labor costs associated with liner maintenance

Centralized Automated Greasing System | Technical Basis: Programmable lubrication unit serving all key crusher bearings | Operational Benefit: Ensures consistent, correct lubrication intervals without operator intervention; provides fault alerts for flow issues | ROI Impact: Extends bearing service life by up to 40%, preventing costly unscheduled bearing failures

6. APPLICATION SCENARIOS

Granite Quarry Expansion Project in Southeast Asia

Challenge: An existing quarry needed to double output but had space constraints for new primary crushing infrastructure. The existing plant suffered from low throughput and daily blockages.
Solution: Implementation of a single highcapacity PEV145 primary jaw crusher plant with an optimized deepchamber design and hydraulic toggle system replaced two older units.
Results: Achieved a 120% increase in primary circuit throughput within a similar footprint. Blockagerelated downtime decreased from an average of 10 hours/week to under 1 hour/week.

HighAbrasion Basalt Operation in North America

Challenge: Extremely abrasive basalt was causing jaw plate wear costs to become prohibitive at over $0.12 per ton processed.
Solution: Deployment of this crushing plant equipped with proprietary TIC insert hybrid jaw plates and a centralized automated greasing system.
Results: Field data shows jaw liner life increased by approximately 70%, reducing wear cost per ton to under $0.07. Consistent automated lubrication contributed to zero bearingrelated failures in the first two years of operation.
