150-200 tph Stone Crusher Plant

Why choose two-stage crushing instead of three-stage?

Most 150-200t/h lines targeting medium-hard rock can skip the tertiary cone stage entirely. Here's the math: a PE750×1060 jaw reduces ≤425mm feed to 80-150mm in one pass; the PFW1315 impactor then takes that output directly to 0-40mm finished product. Eliminating the cone crusher saves $35,000-50,000 in equipment cost, removes one screening loop, and cuts maintenance headcount. The trade-off? If you need sand-making with ≤8% needle flake content for high-spec concrete, add the tertiary VSI. Otherwise, this two-stage line is your best ROI path.

Material suitability and product control

• Limestone (Mohs 3-4): The ideal material for this line. Low abrasion means blow bar intervals stretch to 400+ hours, and PFW impact crushing naturally produces cubical aggregates favored by asphalt and ready-mix plants.

• Granite (Mohs 6-7): High hardness demands chromium-alloy blow bars. The PFW1315's hydraulic opening lets operators adjust the gap in under 5 minutes — critical when switching between 0-5mm sand production and 10-20mm coarse aggregate runs.

• Basalt (Mohs 5-6): Abrasion is the main challenge. We recommend ceramic-insert blow bars and limiting rotor speed to 550-600 RPM for extended service life. Typical wear part cost: $0.12-0.18 per ton processed.

• Finished product sizing is controlled at the 3YK2160 vibrating screen. Swap mesh panels to shift output ratios: finer mesh for more 0-5mm sand, coarser for dominant 10-20mm and 20-40mm fractions.
