The 200-ton granite crushing and sand making production line solution adopts the overall operating principle of "more crushing and less grinding", and has the characteristics of high efficiency and good finished products.
WhatsAppOur 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.
