Mine-To-Mill Optimisation: Effect Of Feed Size On Mill

Modifying blasting practices to achieve a more suitable mill feed size – which varies according to the crushing/grinding circuit – can achieve up to a 30% increase in throughput. Following an initial benchmarking of an operation's practices, SRK can advise on how value-added blasting will deliver improvements in both mill capacity and overall consistency of performance.

Jet mill working principle

For mills of 200-300 mm, the feed size can be a maximum of 1.5 mm. For smaller-size mills, the feed size is correspondingly finer. There are several factors, both operational and physical, which affect the fineness of the end product, such as feed rate, nozzle size, nozzle pressure, nozzle angle, airflow rate, feed particle size, chamber diameter and width, and product outlet diameter.

The size of both the feed surge bin and the feeder is based on the bulk density of the feed material. For materials with very low bulk densities, the feed chute to the mill should be carefully designed to prevent plugging. The bulk density can also be used to estimate the weight of the material bed in the grinding chamber during jet milling.

Effect of Rod Mill Feed Sizing on Grinding Performance

30-03-2018· There is no reported evidence that feed size has any effect on rod mill power draw. Because the solids in the rod mill are known to appreciably expand the mill charge (as observed in the charge level before and after grinding out the mill), there would likely be a tendency for power draw to be lower with coarser feeds and at higher feed .
