The client's fine crushing plant originally used an old φ1650 spring cone crusher, but it suffered from insufficient capacity and high circulating load, failing to meet the requirement of processing approximately 13 million tons of iron ore annually. Therefore, the client purchased HPT300 and HPT500 multi-cylinder hydraulic cone crushers from SBM for the fine crushing plant upgrade project.

After comparative testing of different systems, the data showed that the SBM HPT crusher's processing capacity reached 1.9 times that of the original crusher, and the product particle size distribution of the crushed material from the SBM HPT crusher was also significantly improved. The upgrade results were very significant. Currently, the production line continues to operate continuously at high intensity, and the SBM HPT multi-cylinder hydraulic cone crusher maintains a low failure rate and maintenance rate, and has completed most of the iron concentrate production target.
