A jaw crusher production line, also known as a stone crushing plant or aggregate production line, is an integrated system of machines designed to crush large rocks and raw materials into smaller, specified sizes for various applications like construction, road building, and concrete production.
The jaw crusher serves as the primary crusher in this line, meaning it performs the first and most heavy-duty stage of crushing.
The configuration follows the logical flow of material from large to small. Here are the essential components in order of operation:
1. Feeding Stage
Hopper: A large, funnel-shaped container where raw material (like blasted rock from a quarry) is initially loaded by excavators or loaders. It acts as a temporary storage buffer.
Vibrating Feeder (or Grizzly Feeder): This is a critical piece of equipment positioned beneath the hopper. Its functions are twofold:
Regulates Flow: It uses vibration to provide a steady, controlled flow of material into the jaw crusher. This prevents the crusher from being overloaded (choked) or under-fed (running empty), ensuring maximum efficiency.
Pre-Screening (Grizzly): Many feeders have a "grizzly" section with parallel bars. This allows smaller rocks and soil that don't need primary crushing to bypass the jaw crusher, reducing wear and tear and increasing overall capacity. This fine material is collected on a conveyor belt below.
2. Primary Crushing Stage
Jaw Crusher: This is the heart of the primary stage. It crushes large rocks through compression. A fixed jaw plate and a moving (swing) jaw plate form a V-shaped crushing chamber. The moving jaw applies immense force, breaking the rock as it moves down the chamber until it is small enough to pass through the discharge opening at the bottom.
