⚙️ Working Principle

Driven by an electric motor, the rotor disc with mounted hammers rotates at high speed. When material enters the crushing chamber, it is struck by the rapidly moving hammers and propelled against impact plates. The material is further broken down through high-speed collisions and friction between particles. Qualified material exits via the discharge port, while oversized fragments are returned for further crushing.

🧱 Applicable Materials

PCZ Heavy Hammer Crushers are designed for medium-hard and brittle materials with compressive strength typically ≤150–200 MPa.

✅ Primary Suitable Stone Types

1. Limestone – Compressive strength <150 MPa; the most typical application

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

3. Coal Gangue – High brittleness, low abrasiveness; performs very well

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

⚠️ Conditionally Suitable Stone Types

(must meet strength requirements)

• Dolomite (≤200 MPa)

• Sandstone (medium hardness)

• Marble (≤200 MPa)

• Low-abrasion Basalt (strength verification required)

❗ Critical Limitations

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

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

• Not recommended (without verification): High-hardness materials such as granite or iron ore

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

💡 Equipment Advantages

PCZ heavy hammer crushers offer one-step crushing and shaping, ideal for projects with capacities up to 600 t/h, eliminating the need for secondary crushers and reducing investment and operational costs by up to 40%. With a large feed capacity (≤1200 mm), the crusher is suitable for medium-scale crushing in mining, building materials, and chemical industries.

Note: Final equipment selection should be based on the material’s compressive strength, abrasion index, and compatibility with the model specifications.
