Sand Production Line Setup at Haldwani-Lalkuan Stone Crusher

The Haldwani-Lalkuan region’s stone crushers operate high-efficiency sand manufacturing lines combining jaw crushers, cone crushers, and vertical shaft impactors (VSI). Typical configurations process 200-300TPH of basalt/granite into 0-5mm manufactured sand (M-Sand) and graded aggregates.

Core Equipment Specifications

<

Equipment Model Power(kW) Capacity(t/h)
Primary Jaw Crusher PE750×1060 110 150-250
Secondary Cone Crusher HPT300 315 180-360
Tertiary VSI Crusher S8-1145DR 250×2 200-280
Screening System 3YK3072+2YK2460 37×5 -400tph

Crusher-to-Sand Conversion Process Flow:

1. Primary crushing reduces feed size below 150mm

2. Secondary crushing achieves 40mm intermediate product

3. VSI shaping produces cubical particles with ≤3% flakiness

4. Air classifiers remove excess fines (<75μm)

FAQ Section:

A: What’s the typical sand yield ratio?

Q: Approximately 35-40% of raw stone converts to M-Sand.

A: How to control powder content?

Q: Our VSIs with waterfall feeding achieve ≤10% passing 150μm.

A: Dust suppression methods?

Q: Fog cannons + dry fog systems maintain <10mg/m³ emission.
