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:

Unscheduled Downtime: Frequent liner changes, unexpected mechanical failures, and clogged chambers halt your entire processing line. Industry data indicates that each hour of crusher downtime can cost over $10,000 in lost production and labor.
Rising Operational Costs: Are you constantly battling high energy consumption per ton of processed material, coupled with the escalating expense and frequency of wear part replacements?
Inconsistent Output & Quality: Fluctuations in feed size or hardness resulting in poor product shape, uneven gradation, and increased recirculating load that bottlenecks secondary crushers and screens.

How do you achieve reliable throughput with predictable maintenance windows and lower costperton? The solution requires a robust foundation: a primary crushing station engineered for durability and efficiency.

2. PRODUCT OVERVIEW: ODM HeavyDuty Primary Jaw Crusher Plant

This product is a stationary or semimobile primary crushing plant centered on a heavyduty jaw crusher. It is designed as the first stage in mineral processing and aggregate production to reduce runofmine ore or blasted quarry rock to a manageable size for downstream conveying and processing.

Operational Workflow:
1. Feed: Dump trucks or loaders deposit raw material into a reinforced hopper.
2. PreScreening (Optional): A grizzly feeder removes fines to bypass the crusher, improving efficiency and reducing wear.
3. Primary Crushing: The core jaw crusher utilizes compressive force to break large stones between a fixed and a reciprocating jaw plate.
4. Discharge: Crushed material is discharged onto a main conveyor belt for transport to the next stage of the circuit.

Application Scope & Limitations:
Scope: Ideal for hard rock mining (granite, basalt), quarrying for aggregate, and construction waste recycling with reinforced concrete. Suited for hightonnage primary reduction.
Limitations: Not designed for abrasive metal ores better suited to gyratory crushers at very high capacities (>3000 tph). Requires prepared feed; maximum lump size is limited by crusher inlet dimensions.

3. CORE FEATURES

Deep Crushing Chamber & Optimized Kinematics | Technical Basis: Increased nip angle and longer stroke | Operational Benefit: Enables higher capacity reduction in a single pass, improving throughput by up to 15% compared to conventional designs | ROI Impact: Higher output per operating hour directly lowers fixed cost allocation per ton.

HeavyDuty Fabricated Main Frame | Technical Basis: Stressrelieved steel plate construction with reinforced ribbing | Operational Benefit: Provides exceptional durability against shock loads from uncrushable material, minimizing frame fatigue and risk of catastrophic failure | ROI Impact: Extends total plant service life, protects major capital investment.

Hydraulic Adjustment & Clearing System | Technical Basis: Integrated hydraulic cylinders for toggle tension and chamber clearing | Operational Benefit: Allows operators to adjust CSS quickly under load and automatically reverse the jaw to clear blockages without manual intervention | ROI Impact: Reduces adjustment time by 70% and eliminates hours of dangerous manual clearing labor per incident.

BoltOn Wear Liners & Modular Jaw Dies | Technical Basis: Symmetrical design and standardized mounting hardware | Operational Benefit: Enables rotation/replacement of wear parts from one side of the crusher. Reduces liner inventory requirements through interchangeability | ROI Impact: Cuts scheduled maintenance downtime by up to 40% and lowers spare part holding costs.

PLCBased Automation Interface | Technical Basis: Centralized control with sensors for power draw, CSS monitoring, and bearing temperature | Operational Benefit: Provides realtime operational data for predictive maintenance scheduling. Allows remote monitoring of key performance parameters | ROI Impact: Prevents unplanned stops through condition monitoring; optimizes performance settings for variable feed conditions.
