Figure shows the cyclone classification efficiency curves for magnetite (Fe 3 O 4) and silica (SiO 2) obtained from the survey of an industrial ball mill magnetite grinding circuit. The size separation for silica is much coarser, with a d 50c for Fe 3 O 4 of 29 μm, while that for SiO 2 is 68 μm.

Hydrocyclone in Operation Cyclone in Operation. The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the "OVERFLOW" via a Vortex Finder. The mineral that still requires grinding is named the "UNDERFLOW" via the Apex Finder.

particle size. A grinding mill needs a classifier to extract the particles that have been milled sufficiently finely, and to send oversize particles back to the mill for further grinding. A cyclone does this, with the cyclone overflow being the mill final product, and the underflow reporting back to the mill feed. This

Product from the secondary ball mills is classified by cyclones and cyclone underflow is returned to ball mill feed and cyclone overflow reports to final product which has 80% passing 105 microns. After two stage of deslime cyclones, ore is sent for the reverse flotation to produce final product >65% iron for pallet production.

The ball mill has higher circulation load, it generates only 30 35% of actual fines you require to be called as product. If your product size needed is passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again.

The input of ball mill is water and the mass flowrate feed olivine is 75 ton/hr with various feed particle size, but the most will be 400 microns. While the output of the ball mill is 100 microns. Output of hydrocyclone is 10 microns. Does this process need a sump pump between the ball mill and hydrocyclone?

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.

Ball and Rod Mills. JeanPaul Duroudier, in Size Reduction of Divided Solids, 2016. Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.
