Recently, ALLIS SAGA has successfully completed the overhaul of three cone crushers (two CH870 and one CH880) for Anning Co., Ltd., a leading Chinese enterprise in vanadium‑titanium magnetite.

These units have been operating in harsh mining conditions for a long time, resulting in severe wear, aging, and significant performance degradation, which compromised normal production line operation and necessitated professional maintenance to restore performance.

The ALLIS SAGA expert team conducted a comprehensive inspection and overhaul in strict accordance with OEM standards. After in‑factory commissioning and testing, all technical indicators met the OEM requirements, and the equipment will soon be returned to production.

# Comparison Before and After Maintenance

During the overhaul, the expert team carried out a comprehensive evaluation and inspection. Certain key components, including the upper and lower frames, main shaft, and feed cylinder, were found to have seriously degraded structural performance and were no longer suitable for repair or reuse.

To ensure the long-term stable operation of the equipment and eliminate potential safety hazards, the team replaced certain key components with brand-new parts, restoring the overall performance of the equipment to an optimal state and comprehensively improving both its reliability and service life.
