Encyclopedia saVRee

Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit).

2016-1-10  or ball mills. There are others which use just the force of the ore falling on itself to break it down into a smaller size. These are known as Autogenous or AG mills. Another common mill type uses a combination of both autogenous grinding and ball mill grinding—these mills are known as Semi-Autogenous Grinding or SAG mills.

Close Circuits Ball Mill, बॉल मिल in Radour Road,

We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.

Ball Mill-Closed Circuit Type at Rs 260000/unit

The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then are being separated, and the coarse part being returned to the mill inlet.

Evaluation of grinding circuits for iron ore

The final product of the grinding circuit where the mills were operated in series, was composed of the overflow from the three hydrocyclones operated in the circuit, with P 80 =0.104mm. For the circuit with the ball mills in parallel, line B, each ball mill was fed with 499t/h at 64.7% solids, P 80 = 3.714mm and the mill discharge P 80 =0.153mm.
