When it comes to the powerful and robust world of jaw crushers, two components work in a relentless scissoring motion to break down large rocks and ores: the movable jaw plate and the Fixed Jaw Plate. While the movable jaw does the active crushing, the fixed jaw plate is the unwavering anvil against which all material is compressed. Understanding its role, features, and quality is crucial for optimal crusher performance and productivity.
A Fixed Jaw Plate is a wear part mounted on the front frame of a jaw crusher. As the name suggests, it remains in a fixed position while the movable jaw plate exerts immense pressure against it. This action crushes the feed material trapped between the two plates. Typically made from high manganese steel or other advanced alloys, the fixed jaw plate is designed to withstand extreme impact and abrasion, making it one of the most critical consumables in any crushing operation.
The primary function of the fixed jaw plate is to provide a solid, durable surface for crushing. Here’s how it works:
Material Reception: The feed material (like granite, basalt, or ore) enters the crushing chamber from the top.
Crushing Action: The movable jaw plate moves rhythmically towards the fixed jaw plate, compressing the material.
Size Reduction: The material is fractured and broken down until it is small enough to pass through the gap at the bottom of the crusher, known as the closed-side setting (CSS).
Without a robust fixed jaw plate, the crushing efficiency would plummet, leading to increased downtime and maintenance costs.
Not all fixed jaw plates are created equal. A superior plate is defined by several key characteristics:
Exceptional Wear Resistance: Manufactured from premium materials like Mn18Cr2 or TIC Insert Alloy Steel, our plates offer extended service life, reducing the frequency of replacement.
High Impact Toughness: They can absorb the shock loads from crushing hard and abrasive materials without cracking.
Optimal Design & Profile: The tooth profile (e.g., corrugated, curved, or straight) is engineered to enhance crushing efficiency and produce a more uniform product size.
Precision Fit: A perfect fit to your specific crusher model (like Metso, Sandvik, Terex, and others) ensures stable operation and prevents premature wear on other components.
