Cone crushers are essential equipment in mining and aggregate industries, designed to crush hard and abrasive materials efficiently. One critical aspect that determines their performance is the type of crushing cavity—the space between the mantle and concave where rock is compressed and broken. That is short head cavity, medium cavity and standard cavity.
1. Short Head Cavity (Fine Crushing)
The short head type has a longer parallel zone, smaller feed and discharge openings, and finer product size can be obtained. It is designed for fine crushing, normally used after the medium crushing.
Output: Fine product (typically 3-20mm).
Best for: Producing high-quality aggregates for concrete, asphalt, or sand.
2. Medium Cavity (Intermediate Crushing)
This type of crusher is for middle-stage crushing for balanced feed and product size.
Output: Medium-sized product (10-50mm).
Best for: Versatile applications needing a balance between capacity and finer output.
3. Standard Cavity (Coarse Crushing)
The parallel zone of standard cavity is short, so the finished products are coarse, and the production capacity is high. It is used after primary crushing as the medium crushing machine.
Output: Coarser product (typically 20-100mm).
Best for: High-capacity operations where a bigger feed size is processed, such as initial rock reduction.
Short Head Cavity = Fine output, lower throughput.
Medium Cavity = Balanced performance.
Standard Cavity = High capacity, coarse output.
Selecting the right cavity type ensures optimal efficiency, reduced wear, and desired product gradation. Many modern cone crushers allow quick adjustments to switch between cavity designs, enhancing operational flexibility.
