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: Bearing failures or component wear can halt your entire processing line, costing thousands per hour in lost production and labor.
High Maintenance Costs: Frequent liner changes, part replacements, and associated labor create a significant, recurring operational expense.
Inconsistent Output & Product Shape: Poorly graded aggregate or excessive flaky material can lead to product rejection or reduced value in downstream applications.

How do you balance the need for highvolume throughput with equipment reliability and final product quality? The solution requires a machine engineered not just for power, but for predictable, costeffective performance. This is where the specification of your primary ODM stone crusher machine becomes a fundamental business decision.

2. PRODUCT OVERVIEW: Primary Jaw Crusher

This ODM stone crusher machine is a heavyduty, stationary primary jaw crusher engineered for the first stage of size reduction in quarrying, mining, and demolition recycling operations. Its core function is to accept large feed material (up to 80% of the gape dimension) and reduce it to a manageable size for secondary crushing circuits.

Operational Workflow:
1. Feed Intake: Large raw material (0800mm) is loaded into the vibrating grizzly feeder (optional), which bypasses fines to optimize crusher chamber loading.
2. Compressive Crushing: Material enters the fixed and moving jaw plates. The elliptical motion applies compressive force, breaking rock against rock.
3. Discharge Setting Adjustment: The crushed product size is determined by the closedside setting (CSS), hydraulically adjustable for quick product grading changes.
4. Discharge & Conveyance: Sized material exits at the bottom of the chamber onto a main product conveyor for transport to the next processing stage.

Application Scope: Ideal for hard rock (granite, basalt), abrasive ores, and recycled concrete. Best suited for hightonnage stationary plants.
Limitations: Not designed for final shaping or ultrafine crushing; requires a secondary crusher (cone/impact) for most finished aggregate specifications.

3. CORE FEATURES

Deep Crushing Chamber & Optimized Kinematics | Technical Basis: Increased nip angle and longer vertical jaw plate engagement | Operational Benefit: Enables higher capacity per stroke and reduces bridging; promotes rockonrock crushing in upper chamber | ROI Impact: Higher throughput per kWh, reduced idle time from blockages
HeavyDuty Fabricated Main Frame | Technical Basis: Welded steel plate construction with reinforced stress points | Operational Benefit: Provides longterm structural integrity under maximum load conditions, resisting fatigue | ROI Impact: Extends operational lifespan beyond 15+ years, protecting capital investment
Hydraulic Toggle & Adjustment System | Technical Basis: Replaces traditional mechanical toggle plates with a dualacting hydraulic cylinder | Operational Benefit: Allows remote adjustment of CSS and provides automatic overload protection by releasing tramp metal | ROI Impact: Reduces downtime for setting changes by up to 70% and prevents catastrophic damage from uncrushables
Bolted (NonWelded) Jaw Plate Design | Technical Basis: Highstrength alloy steel plates secured via bolted wedge system | Operational Benefit: Enables fast reversal/replacement of wear parts infield without specialized welding equipment | ROI Impact: Cuts liner change downtime by over 50% and reduces longterm part inventory costs
Centralized Automated Greasing System | Technical Basis: Programmable lubricant injection to all major bearing points from single station | Operational Benefit: Ensures consistent bearing protection, eliminates manual greasing errors or missed points | ROI Impact: Directly extends bearing service life by an average of 30%, reducing major failure risk
