Designed for demanding operations, the Durarok delivers high durability in medium to hard rock applications.
Its unique integrated high-torque direct drive with planetary gears provides efficient power transmission while minimizing mechanical losses and maintenance requirements.
Complementing this is a robust crushing roll design with a spline shaft, engineered to withstand heavy loads and deliver consistent, dependable crushing in tough operating conditions.
Engineered for maximum efficiency and uptime, the Durarok delivers high production capacities while maintaining smooth, reliable operation in demanding environments.
Efficient overload protection safeguards critical components, reducing unplanned downtime and extending equipment life.
An automatic reverse sequence quickly clears blockages to keep material flowing without manual intervention, while low power consumption ensures cost‑effective operation and reduced energy demand, making it an ideal choice for operations focused on productivity and sustainability.
Built for maximum endurance, the Durarok is engineered to minimize downtime and simplify service throughout its life cycle. The high service life of the crushing tools ensures consistent performance over long operating periods, even in demanding conditions.
When maintenance is required, the easy replacement of the crushing roll reduces service time and gets production back online quickly.
A dedicated lifting arrangement for mobilization supports safe and efficient handling during transport or component changes, while integrated maintenance platforms enable ergonomic working, improving safety, accessibility and efficiency for service personnel.
