I. Hourly Output by Equipment Scale
HSM Heavy Industry provides a full series of double roller crushers—ranging from small laboratory models to large mining-scale sand makers. Capacity across different scales includes:
| Machine Class | Hourly Output (t/h) | Typical Applications & Materials |
|---|---|---|
| Small Roller Crusher | 3 – 20 t/h | Ideal for small-to-medium sand plants processing medium-low hardness stone (e.g., limestone, calcite) to 2–10 mm. |
| Medium Roller Crusher | 20 –150 t/h | Widely used in standard sand production lines for crushing cobblestone, limestone, and granite. |
| Large Hydraulic Roller Crusher | 150 – 450 t/h | Engineered for large mining operations and high-capacity aggregate projects demanding continuous mass output. |

II. 4 Primary Factors Influencing Hourly Throughput
- Material Hardness: Softer stones like limestone have lower compressive strength and crush easily, achieving maximum output. Hard stones like granite and basalt reduce crushing speed, leading to lower hourly tonnage.
- Target Product Size: Producing finer finished sand (e.g., 0–5 mm) requires tighter roll gaps. Smaller volume passes through per compression cycle, reducing hourly throughput compared to coarse crushing.
- Feed Size Control: Incoming material must stay within maximum specified feed limits. Oversized boulders cause feeding blockages, uneven bite angles, reduced output, and premature shell wear.
- Maintenance & Shell Wear: Unmaintained wear on roller shells creates local grooving (wider gap in the middle), leading to non-uniform discharge and a drastic drop in crushing efficiency.

Equipment Selection & Capacity Calculation Advice
When designing a manufactured sand production line, avoid choosing models solely by maximum nominal capacity. HSM can match the exact model and customize process solutions based on your raw material type, maximum feed size, required output gradation, and moisture content.
Conclusion: Matching machine scale with correct process design is key to securing stable target output. Contact HSM for precise capacity calculations and customized flowcharts tailored to your project parameters.
