1. PAINPOINT DRIVEN OPENING

Are you managing unpredictable aggregate production costs, excessive plant downtime for liner changes, or inconsistent final product gradation? Inconsistent feed material and equipment limitations directly impact your bottom line through unplanned maintenance, high wear part consumption, and suboptimal yield of highvalue product fractions. These operational challenges translate to tangible costs: hours of lost production, frequent component replacement labor, and revenue lost to offspec material.

What if your primary crushing stage could deliver greater stability to your entire circuit? How would predictable wear life and simplified maintenance affect your operational expenditure? The solution lies in specifying a crusher engineered not just for peak performance, but for sustained, costeffective operation under realworld conditions. This is the focus of a professionalgrade ODM stone crusher plant.

2. PRODUCT OVERVIEW

This ODM (Original Design Manufacturer) stone crusher plant is a stationary primary crushing solution engineered for highvolume reduction of quarried rock, river gravel, and demolition concrete. It is designed as the foundational stage in aggregate production and mineral processing circuits.

Operational Workflow:
1. Feed Intake: Runofquarry (ROQ) material is delivered via dump truck or wheel loader into a rugged vibrating grizzly feeder.
2. PreScreening & ByPass: The grizzly section removes natural fines and subfraction material, directing it to a bypass conveyor to reduce unnecessary load on the crusher.
3. Primary Crushing: Oversize material is conveyed into the heavyduty jaw crusher chamber for compressive size reduction.
4. Product Discharge: Crushed material is discharged onto the main product conveyor for transport to secondary processing or stockpiling.

Application Scope: Ideal for hard rock (granite, basalt), abrasive aggregates, and recycled concrete applications in quarrying, mining, and largescale construction projects.
Limitations: Not designed as a standalone finished product plant; requires secondary/tertiary stages for precise shaping or small aggregate production. Feed size is constrained by the specific model's inlet dimensions.

3. CORE FEATURES

HeavyDuty Jaw Crusher Core | Technical Basis: Forged Eccentric Shaft & Deep Crushing Chamber | Operational Benefit: Sustained high throughput with reduced risk of shaft failure under shock loads | ROI Impact: Lower lifetime cost of ownership and minimized risk of catastrophic downtime
Integrated Grizzly Feeder | Technical Basis: Stepped grizzly bars with adjustable slope | Operational Benefit: Effective removal of fines prior to crushing, increasing crusher capacity and reducing liner wear | ROI Impact: Direct fuel and power savings by not processing alreadysized material; extends wear part intervals
Modular Discharge Conveyor | Technical Basis: Bolttogether sections with standardized idlers | Operational Benefit: Enables rapid reconfiguration of plant layout for different site plans or future expansion | ROI Impact: Reduces installation time/costs by up to 30% compared to welded designs
Centralized Greasing System | Technical Basis: Manifold with lines running to all major bearing points | Operational Benefit: Allows safe, routine lubrication from a single station in under 10 minutes | ROI Impact: Ensures bearing longevity, prevents costly failures attributed to missed manual greasing points
Reinforced Hopper & Support Structure | Technical Basis: Hightensile steel plates with internal ribbing | Operational Benefit: Withstands continuous impact from large feed material and loader operations without deformation | ROI Impact: Eliminates structural repair costs over the plant's lifecycle

6. APPLICATION SCENARIOS

Granite Quarry Expansion Project

Challenge: An existing quarry needed to increase primary output by overcapacity without expanding its crushing pad footprint or requiring extensive new civil works.
Solution Implementation was based on an ODM stone crusher plant featuring a deepchamber jaw crusher for higher reduction ratio and an integrated feeder prescreening system.
Results Achieved a throughput increase of35% on the same footprint while improving overall plant efficiency due to effective fines removal at the primary stage.

Urban Recycling & Demolition Hub

Challenge Processing mixed demolition waste containing rebarreinforced concrete created frequent blockages in traditional impactstyle primary units leadingto excessive downtime
Solution A robust ODM jaw crusher plant with heavyduty flywheelsand hydraulic toggle adjustmentfor uncrushable item release was deployed
