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.

The GoldKacha is APT s signature small scale centrifugal concentrator designed for the recovery of gold and other heavy minerals from alluvial sands crushed ores and dump tailings The unit was developed especially for small mining applications and can process larger tonnages than sluices or panning with higher reco
— Gold containing ore processing technology has been developed by using chemical X ray phase mineralogical X ray fluorescence analyses The results of experiments on the gold recovery from a concentrate with a particle size of 10 and 4 µm are presented including options for direct cyanidation without preliminary oxygen oxidation
— Gold ore separation uses comminution techniques to break down the excavated rock but the material hardly looks like a lustrous yellow orange metal In order to properly free this rich element from the rock the crushing stage has to be followed by a chemically active stage such as the cyanidation process or the carbon in pulp release
— Research on the crushing principle in gold processing is very important for the improvement of beneficiation indexes and the control of beneficiation costs Microscopic Process of Rock Mineral Fracture The crushed ore can be divided into 1 3 sections according to the particle size primary crushing i1 medium crushing i2 and
5 — Extracting gold from the mined rock is a complex process From the time that the ore hoisted from underground and enters the processing plant it takes up to five days before the process of smelting into gold bars can commence Gravity recoverable gold or free gold is processed using centrifugal concentrators which significantly shortens
