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, wear part changes, and unplanned maintenance can halt your entire processing line. Industry averages indicate that every hour of crusher downtime can cost over $5,000 in lost production and labor.
Inconsistent Throughput & Product Shape: Fluctuating feed material hardness and size can cause chokefeeding or cavitation, leading to suboptimal tonnage and poor particle shape that affects downstream screening and secondary crushing efficiency.
Skyrocketing Wear Part Costs: Premature liner wear or catastrophic failure due to uncrushable material not only incurs direct replacement costs but also triggers significant labor expenses for changeouts.

How do you maintain target throughput while controlling maintenance costs and ensuring product specification consistency? The solution requires a machine engineered not just for power, but for predictable, efficient operation.

2. PRODUCT OVERVIEW

The [Your Company Name] Primary Jaw Crusher is a heavyduty, singletoggle crushing machine designed for the first reduction of hard, abrasive quarried stone and recycled concrete. Its robust design addresses the initial size reduction stage where reliability is nonnegotiable.

Operational Workflow:
1. Feed Intake: Large feed material (up to 80% of the feed opening dimension) is loaded into the vibrating grizzly feeder (optional) which bypasses fines to increase primary chamber efficiency.
2. Crushing Stroke: The elliptical motion of the singletoggle jaw exerts high pressure on the feed material at the top of the chamber, initiating breakage immediately.
3. Discharge Setting: The crushed material progresses down the chamber with each cycle, being further reduced until small enough to pass through the closedside setting (CSS) at the bottom.
4. Product Discharge: Crushed aggregate is discharged onto the main plant conveyor for transport to secondary crushing or screening stages.

Application Scope: Ideal for granite, basalt, river gravel, and demolished concrete. Suitable for stationary plants and mobile tracked setups.
Limitations: Not designed for sticky, clayrich materials without prescreening; maximum feed size is defined by modelspecific gape dimensions.

3. CORE FEATURES

Deep Crushing Chamber | Technical Basis: Extended fixed jaw geometry | Operational Benefit: Increases capacity by providing a longer crushing zone and reducing nip angle for improved breakage | ROI Impact: Field data shows a 1015% throughput increase compared to standarddepth chambers with similar power ratings.

HeavyDuty Roller Bearings | Technical Basis: Spherical selfaligning roller bearings with larger loadbearing surfaces | Operational Benefit: Withstand high shock loads from uncrushable material and ensure precise shaft alignment for consistent CSS | ROI Impact: Extends bearing service life by an average of 30%, reducing part replacement frequency and associated downtime.

Hydraulic Toggle Adjustment System | Technical Basis: Integrated hydraulic cylinder replaces traditional mechanical toggle plates | Operational Benefit: Allows remote adjustment of crusher discharge setting (CSS) in minutes for product size changes or liner wear compensation | ROI Impact: Eliminates manual shim adjustment, saving 12 hours of labor per adjustment cycle.

BoltOn Wear Liners | Technical Basis: Modular liner design secured with captive bolts | Operational Benefit: Simplifies liner replacement; side plates can be changed without disturbing main frame structures | ROI Impact: Reduces liner changeout time by up to 50%, minimizing production interruptions.

Automatic Lubrication System (Optional) | Technical Basis: Centralized grease distribution to all key bearing points | Operational Benefit: Ensures consistent lubrication without manual intervention, preventing dryrun damage | ROI Impact: Mitigates risk of bearing failure, a primary cause of catastrophic crusher damage requiring weeks of repair.

Overload Protection via Toggle Tension Rod | Technical Basis: Springrelease mechanism on the tension rod assembly | Operational Benefit: Automatically releases upon encountering tramp metal or extreme overloads, protecting the crusher from major mechanical damage | ROI Impact: Prevents costly repairs to pitman, bearings, and frame; system can be reset quickly to resume operation.

6. APPLICATION SCENARIOS

Granite Quarry Primary Crushing Unit Upgrade

Challenge: An existing granite quarry faced excessive downtime every six weeks for manual jaw crusher CSS adjustment and liner rotation. Product gradation drifted as liners wore.
Solution: Replacement with our JC120 Jaw Crusher featuring Hydraulic Toggle Adjustment.
Results: CSS adjustments are now completed in under 30 minutes during scheduled breaks. Consistent product shape maintained throughout liner life. Annual production increased by an estimated 600 hours due to reduced adjustment downtime.

Recycled Concrete & Demolition Waste Processing Plant

Challenge: Processing variable demolition waste containing occasional rebar and mild steel contaminants led to frequent stallouts and risk of bent shafts in previous crushers.
Solution: Installation of our JC120 with its Overload Protection Toggle system and HeavyDuty Roller Bearings.
Results: Three overload events in the first year triggered automatic release without damage. The plant reset the crusher and resumed operation within an hour each time, avoiding an estimated $40k+ in potential repair costs per event.
