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 stem from the crusher itself. These include premature wear part failure leading to excessive maintenance costs, inconsistent feed size reduction causing bottlenecks in downstream processes, and high energy consumption per ton of processed material. Unplanned stoppages for liner changes or component repair directly impact your throughput and profitability. How can you achieve a lower costperton metric while improving system reliability? The solution requires a machine engineered not just to crush, but to optimize the entire primary crushing stage for total operational efficiency.

2. PRODUCT OVERVIEW

This product is a heavyduty, OEM primary jaw crusher machine designed for the initial reduction of hard rock, granite, basalt, and recycled concrete. Its operational workflow is built for simplicity and robustness: (1) Material is fed into the vibrating grizzly feeder, which bypasses fines to increase effective crushing capacity. (2) Oversize material enters the deep crushing chamber of the jaw crusher, where a highinertia flywheel and aggressive nip angle facilitate efficient breakage. (3) The crushed product is discharged onto the main conveyor at a consistent size, determined by the closedside setting (CSS). This jaw crusher is suited for stationary plant installations and largescale mobile tracked applications. Its primary limitation is in processing claybound or highly abrasive materials without prior scalping, where alternative crusher types may be more applicable.

3. CORE FEATURES

Deep Crushing Chamber & Aggressive Nip Angle | Technical Basis: Kinematic geometry of the swing jaw | Operational Benefit: Promotes firstpass fragmentation, reduces recirculating load and slabby output | ROI Impact: Increases effective throughput by 812%, lowering cost per ton.

HeavyDuty Fabricated Frame with StressRelieved Design | Technical Basis: Finite Element Analysis (FEA) during design ensures uniform stress distribution | Operational Benefit: Eliminates frame fatigue cracking under cyclical loading, extends structural life beyond 20 years | ROI Impact: Eliminates risk of catastrophic frame failure and associated replacement costs.

Hydraulic Toggle Adjustment & Clearing System | Technical Basis: Replaceable hydraulic cylinder for toggle plate tension and overload release | Operational Benefit: Allows rapid CSS adjustment for product sizing and automatic tramp iron release without stopping the crusher | ROI Impact: Reduces downtime for product changes by 70% and prevents damage from uncrushables.

Premium Manganese Jaw Dies with Interchangeable Profiles | Technical Basis: ISO 9001certified alloy steel with optimized tooth profile design | Operational Benefit: Extends wear life by up to 30% over standard profiles, allows rotation of dies for even wear utilization | ROI Impact: Lowers consumable cost per operating hour and extends service intervals.

Spherical Roller Bearings with Labyrinth Seals & Grease Purge | Technical Basis: Oversized bearing housing with multipassage grease purging system | Operational Benefit: Excludes contaminants and ensures consistent bearing lubrication under highload conditions | ROI Impact: Virtually eliminates premature bearing failure, a leading cause of unscheduled downtime.

Integrated Motor Base & VBelt Drive Guarding | Technical Basis: Unified baseplate for crusher, motor, and sheaves with OSHAcompliant guarding | Operational Benefit: Simplifies installation alignment, reduces footprint, and ensures operator safety during operation | ROI Impact: Cuts installation time by 25% and mitigates safetyrelated stoppages.

6. APPLICATION SCENARIOS

Granite Quarry Primary Crushing Station

Challenge A granite quarry faced excessive downtime every three weeks for manual jaw die rotation and replacement (~16 hours downtime), coupled with high energy costs from an older crusher.
Solution Installation of the JC5460 jaw crusher with hydraulic toggle system and premium manganese jaws.
Results Wear part service intervals extended to six weeks. Hydraulic adjustment reduced die change/rotation time to under four hours per event. Plant data showed an annual energy saving of $18,500 at current rates.
