Frequently Asked Questions
Technical support and solutions for HSM Double Roller Crusher users.
Q1: What materials are ideal for the HSM Double Roller Crusher?
The machine is perfectly suited for mid-to-high hardness brittle materials with a compressive strength ≤ 300MPa. This includes iron ore, river pebbles, quartz, limestone, and coal. It is also highly effective for materials with high moisture content (up to 30%) due to its non-clogging design.
Q2: How long do the roller shells last?
HSM roller shells are crafted from high-chromium manganese alloy. Under standard limestone crushing conditions, they typically last 2 to 3 years. For extremely abrasive materials like iron ore, we recommend our Tungsten Carbide Stud rollers for maximum longevity.
Q3: Can I adjust the output particle size during operation?
Yes. Our hydraulic series allows for easy adjustment of the roller gap. By increasing or decreasing the physical distance between the two rollers, you can precisely control the maximum grain size of your discharge material.
Q4: What happens if metal or unbreakable objects enter the crusher?
Our machines are equipped with an automatic hydraulic overload protection system. The rollers will instantly retreat to allow the “tramp metal” to pass through and then reset to the original position immediately, preventing any damage to the internal components.
