iron ore grinding density

Blog: Measuring density in grinding circuits 3/3 Rhosonics

4/3/2020· If the cyclone keeps returning ore to the ball mill, the total volume of ore will be increasing in the grinding circuit, as is the density of the slurry. The recirculating ore is also called circulating load. If the grinding process becomes less efficient, the circuit load will climb until its volume is greater than can be handled. The density meter can be applied in the grinding circuit as a warning system.

iron ores were 8.9, 6.5, 25, and 15.8%, respectively for wet and dry grinding. Variation in D/L indicates that abrasion is a prominent phenomenon in dry grinding and chipping is more prominent in wet grinding especially for material with bedded structures.

If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.

The slurry enters a grinding chamber containing grinding media (beads) and rotating discs which provide momentum to stir the charge against a series of stationary counter discs. The particles are ground by attrition between
