Small Spring Roller Crusher FAQ
1. What is the maximum feed size for this small crusher?
Depending on the specific model (e.g., 2PG250x400), the maximum feed size is typically up to 25mm or 30mm. For optimal results and to prolong roller life, we recommend a feed size of less than 20mm for fine sand production.
2. How do I adjust the output particle size?
Adjustment is very simple and purely mechanical. By tightening or loosening the adjustment bolts behind the spring, you can change the gap between the two rollers. This allows you to produce everything from coarse sand to fine mineral powder.
3. What should I do if a piece of iron enters the machine?
Don’t worry! The heavy-duty safety springs are designed for this. When an uncrushable object like iron enters, the springs compress, allowing the rollers to open wider and let the object pass. The rollers then instantly spring back to their original position without stopping the motor.
4. How long do the roller skins last?
HSM uses high-chromium alloy roller skins. For medium-hard materials like limestone, the skins can last over 12-18 months under normal 8-hour daily operation. We also stock replacement parts for fast shipping to minimize your downtime.
5. Does it require a professional engineer for installation?
No. One of the best features of our Small Spring Roller Crusher is its Plug-and-Play nature. It is shipped almost fully assembled. You only need to fix it to a level concrete foundation and connect the power supply. A simple operation manual is provided with every purchase.
