Technical FAQ
HSM Global Customer Support Center
1. What makes HSM’s hydraulic system different from standard springs?
Standard springs lose tension over time, leading to uneven product sizes. HSM’s Hydraulic Pressing System uses active pressure monitoring to maintain a constant crushing gap. This allows for automated “One-Touch” adjustments for different product specifications, saving hours of manual labor.
2. How does the machine react to iron or tramp metal?
Safety is built-in. If an uncrushable object like a steel bolt enters the rollers, the hydraulic system senses the pressure spike and instantly retracts the movable roller. Once the object passes, the cylinders return the roller to its preset position, resuming production immediately.
3. Can I use the Hydraulic Roller Crusher for wet materials?
Yes. The counter-rotating action naturally pulls materials through the crushing zone, preventing the clogging often seen in impact crushers. For very sticky materials, HSM provides specialized surface scrapers to keep the rollers clean and maintain high throughput.
4. What is the expected life of the roller skins?
We use high-chromium, multi-element wear-resistant alloys. Depending on the material hardness, our roller skins typically offer a 30-50% longer lifespan compared to standard cast steel. We also offer surface resurfacing guidance to extend their life even further.
