Hematite ore crusher is the core equipment of iron ore production line. In the selection of hematite ore processing equipment, factors such as the particle size of the finished iron ore and the level of output should be considered. Before the hematite ore processing equipment processes the mine, the existence of slag must be considered, because in the blast furnace smelting process, in order to smelt metal from the ore, there is slag. The hematite ore crusher also considers an efficient process for the recovery of weakly magnetic iron minerals.
C&M Mining Machinery’s Hematite Crusher uses CS Spring Cone Crusher to crush iron ore. The equipment is high-energy, stable, reliable, low-consumption, etc., and is the perfect hematite ore processing equipment.
Grinding mill for hematite ore grinding
In consideration of over grinding in grinding process, the grinding technical efficiency of comminuted hematite products using a high-pressure grinding roller mill and a conventional cone crusher were comparatively studied. Compared with cone crusher products, individual size distributions in high-pressure grinding roller mill product show a more significant “double-peak” characteristic. The results show that high-pressure grinding roller mill products are finer and have a wider full-size distribution because of the greater proportion of fines. high-pressure grinding roller mill products need a shorter grinding time and have a lower relative grindability. high-pressure grinding roller mill products have a lower technical efficiency at a decreasing rate than the cone crusher product for feeds of <2.0 mm and <0.5mm size fractions, and then show a slightly higher technical efficiency for the feed of 0.5−2.0 mm size fraction. Based on the above research, a new process of ultra-crushing in high-pressure grinding roller mill – classified grinding is advanced. The new comminuting process is adopted to reduce ores tonnage into first stage ball mill significantly, improve grinding efficient and weaken overgrinding in the whole grinding process.
