Rock Crusher and Sand Making Production Line Equipment

A rocker box is a traditional mining tool, but modern sand and aggregate production lines rely on advanced crushing and screening equipment. Below is a breakdown of key machinery for efficient rock processing.

Core Equipment Breakdown

1. Primary Jaw Crusher: Handles large rocks (up to 1,500mm feed size), with outputs adjustable from 150–300mm. Models like PE-1200×1500 offer 400–800TPH capacity.
2. Secondary Cone Crusher: Fine-crushing for mid-hardness stones (e.g., HP300, output size: 20–50mm).
3. Vertical Shaft Impact Crusher (VSI): Produces high-quality sand (0–5mm) with low flakiness. Example: VSI1140 (50–200TPH).
4. Vibrating Screen: Multi-deck screens (e.g., 3YK3070) classify aggregates into 0–5mm, 5–10mm, and 10–20mm fractions.
