2. More crushing and less grinding to reduce the feed size into mill. The larger feed size, the more work that the ball mill needs to do on the ore. To achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly.

Traditional taconite pellet-making processes use a rod mill to get the rock to the consistency of coarse sand, and a ball mill to grind the rock into a fine powder. This technology is still in use on Minnesota's Iron Range by some facilities. A taconite plant may have as many as 18 rod mills with one rod alone weighing as much as 500 pounds.

Ball mills are used for mineral grinding because they provide a high-capacity way to reduce the minerals to a fine enough size for whatever end use you many have in mind. The key features of ball mills for this application are: Robustness and simplicity. A ball mill is essentially just a heavily-constructed rotating drum, filled with steel balls.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Regardless of the grinding wheel, though, all grinding processes use abrasive particles to "grind" away material from a workpiece's surface. When a workpiece is exposed to a grinding wheel, some of its material will rub off. With that said, grinding is often used to both remove material from workpieces as well as polish workpieces.

Post-mill grinding will also help you better regulate various grinding processes. When you grind your ingredients individually, some ingredients may be finer or smoother than others. The grain size may not be uniform after these ingredients have been mixed together. You may have to grind up the final batch to address these inconsistencies.
