The Production Process Flow

Our optimized crushing line begins with pre-screening to remove contaminants before primary reduction. The jaw crusher performs initial size reduction to ≤150mm, followed by cone crushers/VSI for cubical shaping. Final products are precisely classified through multi-deck screens into 0-5mm manufactured sand, 5-20mm, and 20-40mm aggregates.

Frequently Asked Questions (FAQ)

Q: What’s the typical output gradation?
A: Our VSI systems produce ≤4.75mm sand with 85% passing 2.36mm sieve and fineness modulus of 2.6-3.0.

Q: How to control dust emission?
A: We integrate mist cannons (30μm droplet size) and baghouse filters (<20mg/Nm³).

Q: Minimum required concrete strength?
A: Recommended feed material ≥25MPa compressive strength.
