Cyclone Mill. UDY Cyclone Sample Mills use a patented* method of grinding. High speed rotation of the impeller and air currents throw particles into, and rolls them around the grinding ring. Particles remain in the grinding chamber until impact-shattering and abrasion make them small enough to flow out the exit with the air current.

Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.

Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling. AG/SAG circuits producing a fine grind (particularly single-stage grinding applications) are often closed with hydrocyclones.

Most phosphate processors choose airswept milling systems due to their ability to remove fine particles from the grinding zone. Due to the cushioning effect from newly introduced feed, this allows the grinding action to be concentrated on the large oversize particles. This results in higher yields and, by minimizing overgrinding, lowers energy consumption.

The ball mill overflow is fed to a Cyclone pack for sorting. The Cyclone separates the ball mill discharge into two streams; the ore that has been ground fine enough to produce a concentrate flows to the lead roughers, while the coarse particles are recirculated back to the ball mills for more grinding.
