⚙️ Working Principle

Driven by the motor, the rotor disc with mounted hammers rotates at high speed. When materials enter the crushing chamber, they are struck by the rotating hammers and propelled toward the impact plate. The materials are further broken by collisions and friction between particles. Qualified particles are discharged through the outlet, while oversized ones return to the crushing zone for further reduction.

🧱 Applicable Materials

Designed for medium-hard and brittle materials with a compressive strength typically under 150–200 MPa.

✅ Ideal Material Types

1. Limestone – Typically <150 MPa; the most suitable material

2. Bluestone – Medium hardness, ≤200 MPa; efficient crushing

3. Coal Gangue – Highly brittle, low abrasiveness; very suitable

4. River Pebbles / Cobbles – Suitable when ≤200 MPa compressive strength

⚠️ Conditionally Suitable Materials (must meet strength limits)

• Dolomite (≤200 MPa)

• Sandstone (medium hardness)

• Marble (≤200 MPa)

• Low-abrasiveness basalt (compressive strength must be verified)

❗ Limitations & Conditions

• Max Compressive Strength: ≤150–200 MPa for most models

• Material Characteristics: Only suitable for brittle, medium-hard, and low-abrasiveness materials

• High-Hardness Materials: Such as granite or iron ore require caution and verification

• Calcium Content Requirement: Some models require Ca content ≥40%

💡 Equipment Advantages

The PCZ heavy hammer crusher enables one-step crushing and shaping, ideal for projects with a capacity under 600 t/h, eliminating the need for secondary crushing and reducing costs by up to 40%. Its large feed size capacity (≤1200 mm) makes it highly suitable for medium-scale crushing tasks in mining, building materials, and chemical industries.

Note: Actual equipment selection must be based on material properties such as compressive strength and abrasion index to ensure optimal model matching.
