Core Overview: Double roll crushers are widely utilized fine-crushing machines across mining, building materials, and coal industries. Equipment choice depends heavily on drive mechanism (spring vs. hydraulic), roll diameter, required capacity (ranging from 2 to 400 t/h), feed particle size, and target product discharge.
Double Roll Crusher
📊 Equipment Classification & Technical Specifications
Double roll crushers are categorized by drive system into spring-loaded (simple structure, economical) and hydraulic (full hydraulic control, easy roll gap adjustment, stable performance).
| Category | Roll Diameter | Max Feed Size | Capacity | Ideal Application |
|---|---|---|---|---|
| Small Spring Double Roll Crusher | 400 – 800 mm | 25 – 40 mm | 2 – 50 t/h | Small-to-medium sand/aggregate plants |
| Medium Hydraulic Double Roll Crusher | 750 – 1000 mm | ≤ 40 mm | 20 – 100 t/h | Medium aggregate production lines |
| Large Hydraulic Double Roll Crusher | 1200 – 2000 mm | ≤ 120 mm | 100 – 400 t/h | Large-scale crushing operations (>300 t/h) |

💡 Key Equipment Selection Criteria
- Material Hardness: Suited for brittle materials with low to medium hardness, typically under 260 MPa compressive strength.
- Feed Size Limits: Verify that input lump size remains within the specified maximum feed envelope for the target unit.
- Target Throughput: Match plant capacity directly—small lines favor spring models, while medium to large lines require hydraulic series.
- Discharge Requirements: Adjust the roll gap directly to fine-tune final product size according to concrete or construction specs.
Summary: Selecting the correct double roll crusher model ensures optimized power usage and product gradation. Huashengming Heavy Industry offers both spring and hydraulic series, along with material sample testing, to help determine the exact model for your site conditions.
