In November 2023, Shunda Mining Group signed a contract with the Russian KGOK project for two sets of iron ore rock discharge systems, the SMG6089 semi-mobile rotary crushing station, with the delivery date set for May 10, 2025. The signing of this contract marks the entry of the semi-mobile rotary crushing station designed and manufactured in China into the international market.
The SMG6089 semi-mobile rotary crushing station designed and manufactured by Shunda Mining for the Russian iron ore project has a minimum temperature of -44 ° C at the project site. The overall design of the crushing station meets the operating conditions of -41 ° C. The height of the crushing station is 24 meters, the feeding Angle is 90º, the maximum feeding particle size is ≤1400mm, the output particle size P80 is ≤250mm, and the maximum processing capacity is 5,500 tons per hour. Two SDG6089 gyratory crushers are selected.
The supply range of the SMG6089 semi-mobile gyratory crushing station includes: gyratory crushers, discharge belts, E-House, cantilever cranes, hydraulic hammers, dry mist dust suppression systems, bag dust removal systems, magnetic separators, metal detectors, belt scales, fire protection systems, etc. The main structure of this crushing station adopts a modular design to meet the relocation requirements of users for semi-mobile crushing stations.
The biggest technical difficulty of this semi-mobile rotary crushing station lies in the 90 ° feeding and ultra-low temperature working environment. The 90 ° feeding method of the crushing station has broken the traditional 180 ° symmetrical feeding method, causing significant changes in the main structure and force of the crushing station, and also resulting in a change in the feeding method of the gyratory crusher. Facing this series of major technical challenges, the R&D team spent nearly two months on technological breakthroughs and completed the design of China's first 90 ° feeding semi-mobile gyratory crushing station, which passed the technical review of a third-party research institution. This marks a new step forward for Shunda Heavy Mining Group in the field of semi-mobile gyratory crushing stations.
At present, the SDG6089 gyratory crusher has entered the final processing stage and is expected to complete the factory trial run in mid-April.
In January 2025, the project management team of the KGOK iron mine in Kovsky, Russia, came to Shunda Mining for a phased process inspection. All the indicators of the random inspection met the design requirements.
The steel structure of the SMG6089 semi-mobile rotary crushing station entered the assembly stage on March 7th, was gathered at the port on May 10th, and is expected to be put into operation on-site in Russia by the end of 2025.
