Understanding the Closed Side Setting for the Premiertrak 1165 Jaw Crusher
The Premiertrak 1165 is a high-performance mobile jaw crusher designed for demanding applications in quarrying, mining, and recycling. One of the critical parameters affecting its performance is the closed side setting (CSS), which determines the smallest output size of crushed material. Proper adjustment of the CSS ensures optimal efficiency, product quality, and wear life of the crushing components.
What Is Closed Side Setting?
The closed side setting refers to the narrowest gap between the fixed and moving jaw plates at the bottom of the crushing chamber. This setting directly influences the size of the crushed product—smaller CSS values produce finer material, while larger settings allow coarser output. For the Premiertrak 1165, adjusting this parameter correctly is essential for achieving desired gradation and maximizing throughput.
How to Adjust CSS on Premiertrak 1165
The Premiertrak 1165 features a hydraulic CSS adjustment system, allowing operators to modify settings quickly without manual intervention. Here’s how it works:
1. Accessing Adjustment Controls – The crusher’s hydraulic system enables remote CSS adjustments via a control panel or automated settings depending on configuration.
2. Setting Range – The typical CSS range varies depending on jaw plate selection but generally spans from approximately 50mm (2″) down to 6mm (0.25″).
3. Monitoring Output – After adjustment, operators should verify product size distribution using sieving or particle analysis tools to ensure consistency.
Importance of Correct CSS Selection
Choosing an appropriate closed side setting impacts several aspects of crusher operation:
– Throughput Capacity – A wider CSS increases production rates but may reduce fines generation for certain applications.
– Wear Life Optimization – Properly set CSS reduces unnecessary stress on jaw plates and extends component lifespan.
– Product Quality Compliance – Meeting specifications for road base, concrete aggregates, or asphalt requires precise control over output gradation.
Best Practices for Maintaining Optimal Performance
To maximize efficiency when operating a Premiertrak 1165:
– Regularly check wear on jaw plates—uneven wear can lead to inconsistent output sizes even with correct CSS settings.
– Use factory-recommended guidelines when selecting initial settings based on feed material hardness and desired end product specifications.
– Monitor hydraulic pressure during adjustments—excessive force may indicate
