The original production line of Inner Mongolia magnetite crushing and beneficiation project was inefficient, with frequent equipment failures. Liming technical support team improved the crushing efficiency and capacity by replacing coarse crushing equipment and optimising medium crushing equipment. The customer was satisfied and cooperated with Liming to build more iron ore crushing production lines in many places, which verified the effect of technical transformation.

In a magnetite ore crushing and beneficiation project in Inner Mongolia, the customer faced the problem of mismatch of production line process design, which resulted in low efficiency and substandard capacity of three-stage crushing operation. In addition, the original PE jawbreaker and cone crusher had frequent failures, and the after-sales service failed to follow up in time, which seriously affected the continuity and stability of production. For this reason, the customer sought Liming's technical support to carry out technical diagnosis and upgrading of the existing production line.

Liming technical engineers put forward a targeted system upgrading programme after a field inspection of the production site:

1. Replacing the coarse crushing equipment: adopting C6X series V-cavity jawbreaker to replace the original PE jawbreaker, which solves the problem of "jamming" in the coarse crushing stage and improves the crushing efficiency by more than 20%.

2. Optimisation of medium crushing equipment: HST single-cylinder hydraulic high-efficiency cone crusher is introduced to replace the old cone crusher, which improves the crushing ratio of medium crushing, reduces the pressure of fine crushing and screening operations, optimises the distribution of crushing ratio of the production line, and improves the overall crushing efficiency and production capacity of the production line.

Project results

After the technical reform, the performance of the production line has been significantly improved in all aspects, and the customer is very satisfied with it. On this basis, the customer cooperated with Liming to build several iron ore crushing lines in Baotou and Bayannur, with annual outputs of 2.5 million tonnes, 6 million tonnes and 3.5 million tonnes respectively. The successful implementation of these new projects further verifies the effect of technical transformation in improving production efficiency and stability.

Case Summary

Through technical transformation, the 12 million tonnes per year iron ore processing project in Inner Mongolia has significantly improved production efficiency and stability, solved many technical problems of the original production line, and reached the expected production target. Liming's professional technical support and customised solutions in the project were highly recognised by the customer, laying a foundation for more cooperation in the future.
