Double Stage Crusher: Frequently Asked Questions
Expert insights into solving clogging issues and optimizing material crushing efficiency.
Q
How does the HSM Double Stage Crusher prevent clogging with wet materials?
The primary innovation is our screenless (sieve-free) design. Traditional crushers fail because wet material sticks to the bottom mesh. By removing the sieve entirely, the HSM system allows crushed material to discharge instantly via gravity. Even with moisture levels exceeding 10-15%, the flow remains 100% continuous without “pasting” or blockage.
Q
What kind of discharge fineness can I expect?
Through our Dual-Rotor Relay Crushing technology, material is effectively crushed twice within milliseconds. This series-crushing logic ensures that 80% of the final output is under 3mm, making it ideal for brick making, power plant fuel preparation, and fine ore processing.
Q
How is maintenance handled for the internal hammers?
Maintenance is streamlined via our Hydraulic Power-Open casing. Instead of labor-intensive manual disassembly, a hydraulic cylinder opens the machine shell at the touch of a button. This provides immediate access for rotating or replacing the high-alloy hammers, reducing service downtime by more than 60%.
