This means that the number of crushing stages can be reduced depending on the feed size accepted by primary grinding stage. Image of a "Classical" 3-stage ore crushing prior to rod mill [image: (135-5-1)] Diagram of Typical 1-2 stage ore crushing prior to AG-SAG mill [image: (135-5-2)] Calculation of Reduction Ratio in Crushing
2008-8-1 · The rock from the crushing plant needs to be reduced typically from the range 1–10 mm down to 0.05–0.1 mm in order for the flotation to work efficiently. For this size reduction, from 1 to 10 mm, down to the range 0.05–0.1 mm, wet tumbling mills are often used, in combination with hydrocyclones for size classification.
Another equation proposed earlier (Allis-Chalmers, 1953; Flavel, 1977) gives the circulating load ratio Rg as a function of e and x, 1 1 x e Rg (2) where e is the % efficiency of the oversize removal, 100 x u is the percent oversize in the crusher discharge, and Rg is the circulating load ratio expressed as fraction of the new feed F.
2021-12-17 · Increasing the circulating load to 500% brings that value up to 2.6 times, for a further relative productivity increase of 30% (2.6/2.0 =1.30)." By keep on increasing the circulating load, typically you reach a point where the mill is overfilled and milling efficiency decreases. thus, there is an optimum circulating load.
High Reduction (HR) concave has a unique shelf design that increases the pressure in the crushing chamber. This has proven to offer up to 10% more final product in tertiary applications compared to conventional designs, and offers up to 19% less recirculating load creating a more efficient crushing circuit.
2021-12-17 · RiverStone''s vice president, Mike Ellis, recently calculated the circulating load ratios of the new Patriot Cone. He reports that at a closed-side setting of 1-inch, the cone processes finished product at a 78-percent throughput; and at a ½-inch closed-side setting, the throughput percentage reaches a high of 83-percent.

The crushing force is produced by an eccentric shaft. Then it is transferred to the crushing zone via a toggle plate system and supported by the back wall of the housing of the machine. Spring-pulling rods keep the whole system in a condition of no positive connection. Centrifugal masses on the eccentric shaft serve as compensation for heavy loads.
