A ballast crusher is a machine designed to break down large rocks or railway ballast into smaller, crushed stones used primarily in railway track construction and maintenance. Here’s how the process works and its applications:
How a Ballast Crusher Works:
1. Feeding: Large rocks or ballast material (typically granite, basalt, or limestone) is fed into the crusher.
2. Crushing Mechanism:
– Jaw Crusher: Uses compressive force to break rocks between two plates.
– Impact Crusher: Hammers or blow bars strike the material to crush it.
– Cone Crusher: Crushes rocks between a rotating mantle and concave bowl.
3. Screening: The crushed material passes through screens to separate it into desired sizes (e.g., 20–50mm for railway ballast).
4. Output: The final product is uniformly sized, angular crushed stone ideal for drainage and load-bearing in tracks.
Uses of Crushed Ballast:
– Railway Tracks: Provides stability, drainage, and support for sleepers/ties.
– Construction Aggregates: Used in concrete or road foundations.
– Landscaping & Drainage: Acts as a base layer for pathways or erosion control.

Key Features of Good Ballast Stone:
– Hardness (resistant to abrasion).
– Angular shape (for interlocking stability).
– Clean & free from dust/debris (ensures proper drainage).
