The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter ( Figure 8.11 ). The feed can be drywith less than 3% moisture to minimize ball coatingor slurry containing 2040% water by weight.
the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ballsemi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill

Dec 082009 Re: how to estimate the wear rate for Ball mill. Most practical way to by measuring empty height and calculating the % volumetric filling of grinding media.Alternative way to make track of mill main drive kW consumption reduction and add makeup charge according to the extent of fall in power consumption.
The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 18 to 1. Horizontal mills require much smaller mediaas small as 0.05 mm to 2 mm. To read detailed specs and submit a quoteclick here for our metallic media or here for our non-metallic media.

Mill diameter is the nominal inside diameter of the millm. Since we actually need the particles to come off the inside diameter of the mill to be processedthe typical mill speed is 75% of the theoretical criti-cal speed of that mill. Using the above formulassignificant experience of how the grinding process worksand mate-

The water amount in ball mill cylinder is an important index in ball milling process. It reflects the carrying energy of particle materials in ball mill. Thereforethe water amount through ball mill cylinder is corresponding with the material throughput of ball millwhich should be controlled in a suitable limit.

The high unit capacity SAG millball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costswhich has in turn made many low-gradehigh-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al.2012).
b. For dry grindingvolume of the test sample is taken in such a way that the sample and the grinding media volume should always be less than 40% of total mill volume c. In case of wet grinding prepare of sample of 2 kg (approx.) add water to make consistency to 55-60% solid by weight. Here the slurry and ball will separated.
The mill product can either be finished size ready for processingor an intermediate size ready for final grinding in a rod millball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screeninga rod milland some or all of the work of a ball mill.
To solve this problemthe client selected Xinhai energy saving ball mill. The mill is lined grooved ring plate which strengthens the tenacityand increases the contact surface of ballstrengthens the grinding effectand easy to control material particle size. Eventuallythe whole production runs efficiently.
Ball mills are the classic grinding plants: Around the world they are the most common installations. Ball mills convince thanks to their simple principle and low maintenance needs: They are robustdurable and extremely reliable in operation. By using ball mills in closed circuit with a separatortheir efficiency can be increased even further.
Ball mill (also named grinding ball) is one of the most important grinding mills in the mining industry which is used to break all kinds of minerals and other materials in the industries of ore beneficiationconstruction materials and chemical engineering. There are two grinding modes: wet type and dry type.
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber.
