FAQ: Hydraulic Double Roller Crusher
Everything you need to know about high-efficiency fine crushing and sand making.
Q: How does the hydraulic system improve over traditional manual adjustment?
The hydraulic system allows for on-the-fly gap adjustment. Operators can change the output size via a control panel without stopping the machine. Additionally, it provides “intelligent protection”—automatically opening the rollers to discharge uncrushable materials (like iron tramp) and resetting instantly to prevent equipment damage.
Q: What makes the roller skin “durable” in harsh environments?
HSM roller skins are cast from high-chromium manganese steel alloy. This material is specifically treated for wear resistance against abrasive ores. Under standard operating conditions, our roller skins offer a service life 3 to 5 times longer than common market alternatives. Furthermore, our modular design makes replacement fast and easy.
Q: Can this machine handle materials with high moisture content?
Yes. Because the double roller crusher operates on a slow-speed extrusion principle rather than high-speed impact, it is far less likely to clog when processing materials like wet clay, shale, or coal gangue. It is widely used in the brick and cement industries for exactly this reason.
Q: What is the power requirement for a 200TPH capacity?
For our 2PGY1500×1200 model, which delivers 150-200 TPH, the motor requirement is 2 × (132-160) kW. Despite the high throughput, the static pressure principle ensures that energy consumption per ton of finished product is 20-30% lower than traditional crushers.
