1. PAINPOINT DRIVEN OPENING

Managing primary rock reduction is a critical bottleneck with direct consequences for your bottom line. Are you facing these persistent operational challenges?

Unscheduled Downtime: Frequent mechanical failures and lengthy component changes halt your entire processing line, costing thousands per hour in lost production and idle labor.
Inconsistent Output & Product Contamination: Fluctuating feed size and wear lead to an outofspec product mix. This results in costly recrushing, wasted material, and rejected loads that damage client relationships.
Excessive Maintenance Costs & Labor: The traditional cycle of reactive repairs—replacing liners, bearings, and other wear parts—consumes both your maintenance budget and skilled technician hours.
High Energy Consumption per Ton: Inefficient crushing chambers and outdated drive systems translate directly to inflated power bills, eroding profit margins on every ton processed.
Safety Risks During Servicing: Manual adjustment and clearing of blockages expose personnel to significant risk, creating potential for serious incident.

What if your primary crusher could transform from a source of volatility into a pillar of predictable, profitable operation?

2. PRODUCT OVERVIEW: HEAVYDUTY JAW CRUSHER

The cornerstone of any hard rock processing plant is a reliable primary crusher. Our heavyduty jaw crusher is engineered for the first reduction stage of dense basalt, granite, and abrasive ores.

Operational Workflow:
1. Feed Intake: Runofmine (ROM) material is delivered via dump truck or loader into the vibrating grizzly feeder (optional), which bypasses fines to increase capacity.
2. Compression Crushing: Material enters the fixed, steepangle crushing chamber where a reciprocating manganese jaw plate exerts immense pressure against a stationary plate, fracturing rock along its natural cleavage lines.
3. Discharge & Setting Control: Crushed material exits at the bottom. The closedside setting (CSS) is hydraulically adjustable under load, allowing quick product size changes without downtime.

Application Scope: Ideal for stationary primary crushing stations in quarrying, mining, and largescale demolition recycling operations. Feed size capacity typically up to 1200mm.

Key Limitations: Not suitable for sticky or clayheavy materials without prescreening. Requires a stable concrete foundation and significant installed power.
