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.

— Double layer pre sintering new process can reduce carbon oxides and nitrogen oxides emission during Iron Ore sintering For the industrial scale pilot with a 360 m 2 sinter machine in 26 weeks the total emission reductions of nitrogen oxides and carbon oxides are tons and tons respectively 2
— Sponge iron is a highly ferrous ore from the direct reduced iron process In order to prevent excessive re oxidation of the sponge iron in the ambient air it must be cooled down in the lower region of the shaft furnace Carburisation as in the blast furnace process does not occur in the DRI process as coke is not used as a reducing agent
The steelmaking processes are considered extremely energy intensive and carbon dependent processes In 2018 it was estimated that the emissions from global steel production represented 7 9% of
— Because the grinding process of cereal feed is very complex it is difficult to measure the relevant parameters directly by sensors Tian et al 2019;Mugabi et al 2017
The size distribution of iron ore pellets is one of the most crucial factors for the quality of pellets A permeable pellet bed permits the easy flow of hot gases through the pellets thereby reducing fuel consumption increasing productivity and improving the quality and uniformity of hardened pellets

A roller screening mechanism was used to remove any undersized material before the green balls enter the final stage of production the induration furnace Process flow chart of iron ore pelletizing industry Pellet plant is facilitated with additives grinding unit as the process of pelletization requires binder and additives Bentonite is
— Single deck roller screens consist of a slightly angled deck in relation to horizontal usually 10° to 19° assembled with parallel rotating rolls meticulously gapped to separate fines product on size and coarse pellets Fig 1 Fines are removed on the first three quarters of the length of the screen through the gaps typically wider than 9 mm [1]
Blast furnace uses iron ore as the iron bearing raw materials and coke and pulverized coal as reducing agents and heat source lime or limestone as the fluxing agents The main objective of blast furnace ironmaking is to produce hot metal with consistent quality for BOF steelmaking process
1 The Bessemer Process The Bessemer steel making process consists of blowing air through molten pig iron contained in a special furnace known as a converter which shaped like a huge concrete mixer Fig The converter is made of steel plates lined inside with a refractory material The type of refractory lining used depends upon the character of the
