Q1: What materials are HSM Roller Crushers best suited for?

Our roller crushers excel at processing medium to high-hardness materials (up to 300Mpa), including granite, basalt, river pebbles, quartz, coal gangue, and iron ore. They are the ideal choice for minimizing over-crushing in sand-making lines.

Q2: How long do the roller skins last?

Thanks to our proprietary alloy casting process, HSM roller skins typically last between 1 to 3 years depending on the abrasiveness of the material and daily operation hours. This is significantly longer than standard manganese steel rollers.

Q3: Can I adjust the output particle size?

Yes. For Spring models, it’s adjusted manually via bolts. For Hydraulic models, you can adjust the gap settings in seconds via the control panel or smartphone (if equipped with the Intelligent System), achieving precise sizes from 1mm to 20mm.

Q4: Is the equipment difficult to maintain?

Not at all. HSM crushers feature a simplified mechanical structure. With our central lubrication system and easy-access design, daily checks take less than 15 minutes. We also provide full video guidance for parts replacement.

Q5: Do you support customized voltage for international markets?

Absolutely. We customize motors and electrical cabinets to meet your local standards (220V/380V/440V/480V/660V at 50Hz or 60Hz) to ensure plug-and-play operation at your site.
