1. PAINPOINT DRIVEN OPENING

Are your aggregate production targets consistently undermined by equipment limitations? For plant managers and engineering contractors, the wrong primary crusher creates a cascade of operational inefficiencies. Consider these common challenges:
Excessive Downtime: Unplanned stops for liner changes, blockages, or mechanical failures halt your entire processing line. Every hour of lost production directly impacts your bottom line.
Inconsistent Output & Poor Particle Shape: An illsuited crusher produces an unpredictable gradation curve and excessive flaky material, compromising downstream process efficiency and final product quality.
Unsustainable Operating Costs: High energy consumption per ton, frequent wear part replacement, and high maintenance labor hours erode profit margins.
Rigidity to Feed Material Variation: Fluctuations in feed size, hardness, or moisture content cause throughput drops or choking, preventing you from adapting to changing site conditions.

Is your primary crushing stage the bottleneck? What would a 1520% improvement in overall plant throughput mean for your annual output? The solution begins with selecting the correct foundational equipment.

2. PRODUCT OVERVIEW: ODM HeavyDuty Primary Jaw Crusher

The ODM heavyduty primary jaw crusher is engineered as the first stage in mineral processing and aggregate production lines. It is designed for highcapacity, reliable size reduction of quarried rock, runofmine ore, and demolition concrete.

Operational Workflow:
1. Feed Intake: Runofmine or quarryrun material is directly dumped into the vibrating grizzly feeder (optional), which bypasses fines to optimize crusher chamber loading.
2. Compressive Crushing: Material enters the fixed and movable jaw cavity. The robust eccentric shaft drives the movable jaw in an elliptical motion, applying immense compressive force to fracture the material against the stationary jaw.
3. Discharge Setting Adjustment: The crushed product size is precisely controlled by hydraulically adjusting the gap at the discharge point (CSS), allowing quick changes for different product specifications without downtime.
4. Discharge & Conveyance: Sized material exits at the bottom and is conveyed to secondary crushing or screening stages.

Application Scope & Limitations:
Scope: Ideal for hard rock (granite, basalt), abrasive ores, and recycled concrete with compressive strengths up to 400 MPa. Serves as the primary crusher in stationary plants for mining, largescale quarrying, and major infrastructure projects.
Limitations: Not suitable for sticky, plastic materials like clayrich ore without prescreening. Requires a stable foundation and significant capital investment compared to mobile units. Maximum reduction ratios are typically 6:1 to 8:1.

3. CORE FEATURES

Deep Crushing Chamber & Optimized Kinematics | Technical Basis: Increased feed opening depth and steeper nip angle | Operational Benefit: Enables acceptance of larger feed blocks while promoting a continuous crushing action with less risk of bridging | ROI Impact: Higher effective capacity per cycle reduces total operational hours for same output

HeavyDuty Fabricated Main Frame | Technical Basis: Highstrength steel plate construction with reinforced stress points | Operational Benefit: Provides longterm structural integrity under maximum load conditions, resisting fatigue and deformation | ROI Impact: Extends machine service life beyond decades, protecting capital investment

WedgeBased Discharge Setting Adjustment System | Technical Basis: Hydraulically assisted wedge mechanism for CSS adjustment | Operational Benefit: Allows operators to change product size settings in minutes without manual shim manipulation | ROI Impact: Minimizes nonproductive adjustment time by over 80%, increasing plant flexibility

Toggle Plate Safety System | Technical Basis: Designed sacrificial cast iron toggle plate with overload protection function | Operational Benefit: Acts as a mechanical fuse; fractures under uncrushable material pressure (e.g., tramp metal), preventing catastrophic damage to other components | ROI Impact: Avoids costly repairs to pitman assembly or main bearings from overload events

HighPerformance Bearing Housings | Technical Basis: Spherical roller bearings mounted in precisionmachined housings with labyrinth seals | Operational Benefit: Supports heavy radial and thrust loads from eccentric shaft operation while effectively excluding dust ingress | ROI Impact: Ensures bearing service life aligns with major overhaul cycles, reducing premature failure risk

BoltOn Wear Liners Design | Technical Basis: Manganese steel jaw plates secured with bolted connections on machined surfaces | Operational Benefit: Simplifies liner replacement procedure; reduces changeout time compared to welded designs | ROI Impact: Cuts maintenance downtime by several hours per changeout event
