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 include:
Excessive Wear & Maintenance Costs: Frequent replacement of manganese steel wear parts due to improper crushing dynamics, directly impacting your consumables budget.
Unscheduled Downtime: Mechanical failures or blockages that halt your entire processing line, costing thousands per hour in lost production.
Inconsistent Output & Product Shape: Poorly graded aggregate with excessive flaky material, reducing product value and causing issues in downstream processes.
High Energy Consumption: Inefficient crushing chambers and drive systems that translate to unsustainable power costs per ton of material processed.
Rigid Configuration Limitations: Fixed crushers that cannot adapt to changing feed material or project requirements, forcing costly workarounds.

What if your primary crusher could transform these pain points into measurable gains in reliability, product quality, and total cost of ownership?

2. PRODUCT OVERVIEW

The ODM Stone Crusher Machine is a heavyduty, primary jaw crusher engineered for the initial reduction of hard rock, granite, basalt, and abrasive aggregates. Its robust design is focused on maximum uptime and lowest costperton in demanding quarry and mining applications.

Operational Workflow:
1. Feed Intake: Large feed opening accepts runofmine material directly from haul trucks.
2. Crushing Action: A deep, symmetrical crushing chamber and aggressive nip angle facilitate efficient compressive breaking of stone.
3. Discharge Setting: A hydraulic toggle adjustment system allows operators to quickly change the closedside setting (CSS) for precise product size control.
4. Discharge & Transport: Crushed material exits at the bottom and is conveyed to secondary screening or crushing stages.

Application Scope: Ideal for stationary quarry plants, largescale mining operations, and major infrastructure projects requiring highvolume primary crushing (typically 2001500 TPH range). Not recommended for recycling mixed demolition waste or highly abrasive silica sand applications without specific configuration.

6. APPLICATION SCENARIOS

Granite Quarry Expansion Project

Challenge: An existing quarry needed to increase primary throughput by 40% but faced space constraints limiting conveyor length from the old crusher pad.
Solution: Implementation of an ODM Stone Crusher configured with a steeper discharge conveyor profile was installed on a new pad closer to the blast face.
Results: Reduced truck haul cycle time within the pit by an average of 22%, achieving the targeted throughput increase without expanding the truck fleet.

Basalt Aggregate Production for Highway Construction

Challenge: The contractor’s previous primary jaw crusher produced an unacceptable percentage of elongated particles (>20%), causing segregation in asphalt mixes.
Solution: Replaced with an ODM Stone Crusher featuring the optimized chamber geometry designed for improved particle shape.
Results: Postcrush analysis showed flakiness index reduced by approximately 35%, meeting strict highway authority specifications and improving downstream plant efficiency.
