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 size reduction often include:

High Maintenance Costs & Downtime: Frequent liner changes, bearing failures, and unplanned stoppages for crusher repairs directly impact your bottom line. Can your operation afford 48+ hours of lost production for major component replacement?
Inconsistent Output & Product Shape: Poorly graded aggregate with excessive flaky material fails to meet specifications, leading to rejected loads and reduced revenue per ton. Is your current equipment delivering the consistent cubicity required for highvalue asphalt and concrete mixes?
Excessive Energy Consumption: Older, inefficient drive systems and poor chamber designs result in high kWhperton costs, a significant variable in your operational expenditure.
Rigid Configuration Limitations: Fixed crusher setups struggle to adapt to varying feed materials or changing product requirements, forcing compromises in either throughput or final product quality.
High Total Cost of Ownership (TCO): Beyond the initial purchase price, hidden costs from parts consumption, energy use, and labor for adjustments create an unsustainable financial burden over the equipment’s lifecycle.

The central question is: how can you achieve reliable, costperton crushing without compromising on product quality or operational flexibility?

2. PRODUCT OVERVIEW

This product is a heavyduty jaw crusher engineered as a primary stone crusher machine for robust, highvolume reduction of hard rock, granite, basalt, and river gravel. It is designed as a private label solution for OEMs and large distributors seeking reliable performance with competitive pricing.

Operational Workflow:
1. Feed Intake: Large feed material (up to specified feed opening) is loaded into the vibrating grizzly feeder (optional), which bypasses fines to increase primary chamber efficiency.
2. Primary Crushing: Material enters the fixed and movable jaw assembly. The elliptical motion of the movable jaw applies compressive force against the fixed jaw, breaking stone via mechanical pressure.
3. Discharge Setting Adjustment: The crushed material exits at the bottom aperture. The closedside setting (CSS) is hydraulically adjustable to control the final product size without manual shim changes.
4. Product Conveyance: Crushed aggregate is discharged onto the main plant conveyor for transport to secondary screening or stockpiling.

Application Scope & Limitations:
Scope: Ideal for stationary quarry plants, largescale mining operations, and major infrastructure project sites requiring primary crushing of abrasive materials with uniaxial compressive strength up to 320 MPa.
Limitations: Not designed as a standalone solution for finished aggregate; requires secondary and tertiary stages for most specification products. Not suitable for recycling mixed demolition waste without significant prescreening due to risk of tramp metal.
