Our production line needed some crushers. We always bought some of European equipment in the past. We investigated SBM this time and found their technology was not worse than the European technology and the price was much lower than that of European equipment.
I knew SBM through a friend. SBM salesman was very enthusiastic and patient when making production scheme for me. After investigating SBM's factories and sample production lines personally, I found that SBM is very professional.
On site, only the road surface requires leveling and compacting to establish working conditions, eliminating the necessity for cement foundation leveling and hardening. This significantly reduces the project's construction material costs.
The iron ore is evenly fed by TSW1139 feeder into HJ98 high-efficiency jaw crusher for coarse crushing. After that, the materials would be sent into CS160 cone crusher for secondary crushing.
In this study a large scale SiC spherical mirror φ360mm was designed as reducing weight structure with many open back triangular cells The ELID mirror grinding technique was conducted to finish the mirror A unique jig composed of many hydrostatic actuators was developed for reducing the deformation resulted from the grinding force
This paper reports the development of an ultra precise grinding system based on a new grinding technique called the Arc Envelope Grinding Method AEGM AEGM which is used for grinding aspheric ceramic mirrors increases both wheel life and grinding performance and significantly decreases total production costs
By using the compensation grinding path the profile accuracy was improved from 35 to 8 mu m in the fine grinding stage The proposed compensation method effectively improves the profile accuracy and manufacturing efficiency for grinding large diameter aspheric mirrors
