Difference and Choice of 2 Common Mills, Ball Mill and Grinding Mill FTM

Ball mills are different. The grinding media is unfixed steel ball, etc., which produces larger sized powder than grinding mill. the size of the discharged product can mainly be adjusted between 40250 mesh. If the size of discharged product is uneven, it is needed to equip a powder separating machine.

How Ball Mill Ore Feed Size Affects Tonnage Capacity 911 Metallurgist

Hard ore Work Index 16 = 100,000/65,000 = kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...

What's the Difference Between Ball Mill, Rod Mill and SAG Mill?

Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...

The ball mill is the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed in ball mills.

How to Choose the Right Types of Ball Mill for Your Application

The processing capacity of the ball mill is determined by the amount of material that can be ground at once. If you have a large volume of material to be ground, you will need a larger mill with a higher processing capacity. ... Vertical ball mills are more energyefficient than horizontal ball mills and can operate at higher speeds. 3 ...

Ball Charge and Grinding Efficiency Grinding Classification ...

Adjusting the ball charge to meet the capacity demand will ensure that it is not overgrinding (if it is overgrinding then it has more capacity than needed and the ball charge can be reduced). In order to maintain good efficiency the grinding circuit should maintain a good circulating load ( 250%).
