The advantages of a ball mill slaker become most apparent, however, when dealing with slower-reacting quicklimes or cold and/or chemically-challenging slaking …
Open Circuit Grinding. The object of this test was to determine the crushing efficiency of the ball-mill when operating in open circuit. The conditions were as follows: Feed rate, variable from 3 to 18 T. per hr. Ball load, 28,000 lb. of 5-, 4-, 3-, and 2½-in. balls. Speed, 19.7 r.p.m.
With applications such as lime slaking or limestone grinding, smaller capacity ball mill systems are often required. In these instances, a cost effective option, when compared to larger trunnion mounted mills, is a roller mounted ball mill. This design uses heavy duty support rollers to drive the rotation of the mill shell directly.
The hardness of the liner and the grinding ball should be above HRC50. This is mainly because the hardness of the hard phase in the abrasive is 6 ~ 7 on the Mohs scale. It is estimated to be close to HRC60. In theory, the hardness of the grinding medium is greater than or equal to eight percent of the hardness of the abrasive.
Here are the 10 ways for your to improve the ball mill performance: Step#1. Change the original grindability. Step#2. More crushing and less grinding to reduce the feed size into mill. Step#3. Reasonable filling rate of steel ball. Step#4. Reasonable size and proportion of steel ball.

Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 150mm according to different grinding requirements. In a cement ball mill, generally, φ50-100mm steel balls are used in the coarse grinding chamber, φ20-50mm steel balls are used in the fine grinding chamber. 2. Short Cylinders.
We feature a great selection of used ball mills from top brand name manufacturers including , FL, Outotec, Kobe Allis, , Hardinge & Denver.

The grinding and crushing of the limestone particles is done by the grinding medium, which are typically steel balls, inside the ball mill. Depending on the size of the limestone feedstock, several sized ball …
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be ...

The operating work index was also calculated for all available full scale mill data and is shown in Figure 16. There is no design data included in this but it should serve as a guide as to what the mills are actually capable of. Recent regrinding designs falling in the lower area of the graph have significantly under quoted actual operating mills.
