Q: How does the spring buffer mechanism protect the machine?
When unbreakable objects (like iron blocks or extremely hard rock) enter the chamber, the spring instantly contracts. This increases the gap between the rollers to let the object pass safely. The system resets in less than 0.5 seconds, ensuring no damage to the body structure.
Q: Is this model really more energy-efficient than a hammer crusher?
Yes. While a hammer crusher relies on high-speed impact which wastes energy, the double roller uses extrusion. This results in a power consumption of only 1.0-1.8kWh per ton of material, making it significantly cheaper to operate long-term.
Q: How difficult is maintenance for small construction teams?
The design is intentionally simple with few wearing parts. The roller shells are made from high-chromium manganese steel and typically last over 2 years. Daily maintenance only requires basic lubrication, which any local mechanic can handle.
