Prediction Of Product Size Distributions For A Stirred Ball Mill

The capacity of a stirred ball mill to grind to a certain product size efficiently depends strongly on the power intensity in the milling chamber. The dependence of power intensity on stirrer speed, slurry density, bead density and the amount of dispersant added to the feed was investigated using a 6-litre 11-kW horizontal stirred ball mill.

A study of comminution in a vertical stirred ball mill the energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the tumbling ball mill although during coarse grinds the media wear was higher in the stirred ball mill than in the tumbling mill. Details Towards A Better Understanding Of Stirred Milling.Although the behavior of grinding media can be accurately simulated, it is not well-established the way to predict particle size distribution after milling by the DEM simulation. The objective of this study was to develop a new method to predict particle size distribution in ball milling using the DEM simulation.

Choosing The Best Media Mill For Your Wet Grinding Application

Stirred-ball attrition mill . Abstract −To develop a high-performance structured catalyst, the fine grinding characteristics of alumina was inves-tigated by a stirred-ball attrition mill. The grinding kinetics approach was successfully applied to the analysis of particle size distributions.A ball mill (483mm x 908mm) equipped with a feed chute was used without media as a mixer as shown in Figure 7. Figure 8 shows the particle size distributions obtained from the Vertimill pilot test. Figure 8 – Particle size distributions obtained from the Vertimill pilot plant (Metso, 2011).

Tumbling ball, stirred, vibratory and fluid energy mills are the most commonly used mill types. A number of factors influence the choice of equipment, including the end-use of the product, required product size distribution, sensitivity of the material to heat, and purity requirements.In this study, a computer simulation of a suitable matrix notation of the Broadbent and Callcott grinding model was written. First, a chromite sample was ground in the laboratory type batch ball mill at different grinding times, with different particle size distributions and different capacities.

Jul 01, 2003 The specific energy is ultimately determined through actual product testing, but there are a few indicators to predict which mill will be the most efficient. Grinding Media Size Effect The ability to operate a mill with smaller-diameter grinding media greatly increases the mill's efficiency and can overall further increase the quality of.A laboratory air-classifying impact mill was used for the dry grinding, and a stirred ball mill (attritor) was used for the wet grinding. Products of as near the same size distribution as possible were prepared by each method, i.e., nominal minus 27 micrometers ( mu m) with a mean particle size of 10 to 12 mu m.

Several studies on stirred ball milling [2, 3, 4], it was reported that the fineness of the product remains the same for a given energy input, regardless of the mill size and the operating conditions. If this is true, scale up of a stirred ball mill should be quite straightfor.In a stirred media mill, the mill body is static and the charge motion is created by an agitator such as a rotating spiral or impeller. We provide both original body liners and spiral impeller liners designed as a system for each of the mill sizes of Metso’s extensive range of stirred media mills.
