1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate production margins? For plant managers and engineering contractors, the core challenges in primary crushing often center on three critical areas: excessive maintenance frequency, inconsistent output gradation, and vulnerability to uncrushable materials. Each unscheduled stop for liner changes or clearing a jam can cost thousands in lost production and labor. Are you constantly balancing the tradeoff between throughput capacity and final product shape? Does the fear of a tramp metal event causing catastrophic damage keep you from maximizing feed rates? The solution requires a machine engineered not just for power, but for predictable, efficient, and protected operation. The right ODM stone crusher machine is the foundational answer to these systemic issues.

2. PRODUCT OVERVIEW

This product is an ODM (Original Design Manufacturer) primary jaw crusher, engineered for hightonnage reduction of hard rock, granite, basalt, and abrasive aggregates. Its operational workflow is built for simplicity and robustness:
1. Feed Intake: Large feed opening accepts runofquarry material with minimal prescreening.
2. Compression Crushing: A steep nip angle and aggressive crushing motion apply immense compressive force to fracture material against a fixed jaw plate.
3. Discharge Setting Adjustment: The closedside setting (CSS) is hydraulically adjustable under load, allowing quick changes to product size without stopping the crusher.
4. Discharge: Crushed material exits the chamber onto the main plant conveyor.

Application Scope: Ideal for stationary quarry plants, largescale mining operations, and major infrastructure project sites requiring primary crushing of materials with compressive strength up to 400 MPa.
Limitations: Not designed for recycling applications with high volumes of rebar or as a secondary/tertiary crusher for fine shaping. Maximum feed size is defined by the specific model’s gape opening.

3. CORE FEATURES

Deep Crushing Chamber & Optimized Kinematics | Technical Basis: Increased feed volume and steeper nip angle | Operational Benefit: Enables higher throughput of large feed material while reducing slippage and wear at the top of the chamber | ROI Impact: Higher tonsperhour (TPH) capacity from the same footprint directly lowers costperton.

HeavyDuty Fabricated Frame | Technical Basis: Stressrelieved steel plate construction with reinforced ribs | Operational Benefit: Provides exceptional durability against shock loads and fatigue over decades of operation, minimizing framerelated failures | ROI Impact: Eliminates costly structural repairs and extends the total service life of the capital asset.

Hydraulic Toggle Adjustment & Clearing System | Technical Basis: Replaces traditional mechanical toggle plates with a dualacting hydraulic cylinder system | Operational Benefit: Allows operators to adjust CSS remotely for product control and automatically reverse the jaw to clear blockages or pass tramp metal | ROI Impact: Reduces downtime for setting changes by over 70% and prevents costly damage from stall events.

Bolted Bearing Cartridges | Technical Basis: Preassembled, selfaligning roller bearing cartridges mounted externally to the main frame | Operational Benefit: Simplifies bearing maintenance and replacement; contamination is minimized compared to sleeved bearings | ROI Impact: Cuts scheduled bearing service time by half and extends bearing life through improved sealing.

WedgeLocked Jaw Die Retention System | Technical Basis: Mechanically locked wedges hold jaw plates securely without backing material | Operational Benefit: Enables faster, safer jaw liner changes; eliminates risks associated with resin pouring or incorrect torqueing | ROI Impact: Reduces liner changeout time significantly, increasing crusher availability.

Integrated Motor Base & Belt Guard | Technical Basis: Unified baseplate design incorporating crusher, motor mounts, and guards | Operational Benefit: Simplifies installation alignment, enhances site safety compliance, and reduces installation labor costs by up to 30%| ROI Impact: Lower total installed cost (TIC) and faster commissioning.

6. APPLICATION SCENARIOS

Granite Quarry Expansion Project

Challenge A quarry needed to increase primary circuit throughput by 25% without expanding their primary crusher foundation or incurring excessive liner costs due to highly abrasive granite.
Solution Implementation of our ODM stone crusher machine featuring our proprietary alloy jaw plates designed specifically for highabrasion applications.
Results Achieved a sustained throughput increase of 28%. Liner life improved by approximately 15%, leading to fewer changeouts annually while meeting all target product specifications.

Major Highway Construction Corridor

Challenge A contractor faced strict project deadlines but had variable feed material (mixed basalt and limestone) causing frequent chokeups in their existing primary crusher.
Solution Deployment of our jaw crusher with its hydraulic toggle clearing system was specified.
Results The crew cleared three minor blockages in under two hours total during the project—a task previously consuming a full shift each time—keeping the mobile crushing spread on schedule despite variable feed conditions.
