How to Solve Low Output Problem of Old Sand Making Machines

A large number of old-generation sand making machines are still in use in small and medium sand plants. Long-term operation leads to aging rotors, blocked flow channels and reduced crushing speed, resulting in low hourly output, high powder content and poor sand grain shape.

Replacing all equipment requires huge investment, while blind production expansion cannot solve fundamental efficiency bottlenecks. Most old sand making lines suffer from low profit due to outdated core structure and unreasonable process matching.

SMP provides targeted upgrading solutions for old sand making equipment. By replacing high-efficiency rotors, optimizing crushing cavity structure, adjusting feeding speed and upgrading screening and powder separation systems, old machines can restore and exceed original design capacity.

After professional renovation, the sand making output increases by 20%–30%, finished sand quality meets commercial standards, and equipment failure rate is greatly reduced. It is the most cost-effective way for old sand plants to improve efficiency and expand production.
