The Proctor hardness of minerals is f 5-8, and the feed particle size of ball mill is F80 15mm. Because the minerals are hard and the feed particle size is large, the design of the ball mill shell liners are the combination of waveform and T-shape, so the design structure of the liner enhances the crushing and grinding effect of minerals. 1.
Uses of a ball mill liner The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.

Figure 3 shows the relative position of grinding balls. When the ball is brought down to a certain height by the rotating ball mill liner, only when x R1 R2, the movement direction V0 of Q1 will not change and form a direct impact on the liner when x R1 R2, Q1 and Q2 pass each other, and the movement direction V0 of Q1 will not change greatly, However, a small amount of friction will ...
Shell liners and ball mill liner The type of ball mill liner known as a shell liner, or The MVLTM, Magotteaux Variable Lift, covers a range of shell liners for everything from fine to coarse grinding. These liners are efficient energy wise and make for low grinding media consumption. They can be assessed continuously via profile studies and the design can be tailored to the customer s needs ...
And, Ball mill liner can be the best way to do that. Consider getting these from the best ball mill liner manufacturer to ensure mill liners benefits. Introduction to ball mill liner Ball mill liner is an optimum and reliable wearing solution even for the toughest ball
Ball Mills Steel Ball Mills amp Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s. The basic construction of a ball mill is a cylindrical container with journals at its axis.

Apr 01, 1988 Fig. 1 shows that in a 2.5 ft 0.76 m diameter inside liners mill, that one 2 inch 50 mm diameter ball reduces the inside diameter of the mill sufficiently to give 70 of critical speed. In a 17.5 ft 5.33 m diameter mill 6.78 ball diameters are needed to obtain the same reduction in mill diameter to give 70 of critical speed.
To characterize the weight loss of the ball mill shell or its liner , three testing coupons of 0.95 cm in diameter and 2.54 cm in height made of high chromium alloy acquired from Magotteaux, Nashville, Tennessee, with the compositions shown
8-3 Centrifugal force outward Fc mpamp 2 Dm 2 8.1 amp is the angular velocity, mp is the mass of any particle media or charge in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg 8.2 The particle will remain against the wall if these two forces are in balance ie.
Ball Mill Liners. Ball mill is a fine grinder. A horizontal or vertical rotating cylinder is filled partially with the balls of ceramics, small rocks, and balls made from stainless steel. The ball charge of a SAG mill is about 29 to 30.
Modern ball mills consist of two chambers separated by a diaphragm. In the first chamber the steel-alloy balls also described as charge balls or media are about 90 mm diameter. The mill liners are designed to lift the media as the mill rotates, so the comminution
With particular reference to mill size, it is apparent that a change in diameter in a large mill is relatively far less significant than the same change in diameter for a small one. For example, using well established relationships between power draw and mill diameter and speed, 50 mm 2 inches of liner wear results in about 14 percent power increase at constant loading and rotational speed ...
Ball Mill Liners. We are regularly supplying rubber liners up to 26 ft diameter ball mills. We design liners to optimize power for maximum throughput and increased liner life. These liners are custom designed for your mills.
