Prediction of product size distributions for a …
In this paper, the difference between ball mill grinding and stirred ball milling is discussed. A size-energy model is proposed for simulation of stirred ball milling. The product size distributions below 10 μm from a stirred ball mill were simulated by the model satisfactorily. The model is simple and has only two parameters. The model was tested under different milling conditions for a stirred ball mill.

Measured (points) and predicted (solid lines) product size distributions using 6.35 mm balls at 160 rpm stirrer speed in a vertical stirred mill as a function of grinding time for a −595 +420 ...
Prediction of the product size distribution in ...
The mill used for this study is a DYNO-Mill KDL laboratory-scale stirred bead mill as shown in Fig. 4.This comprises a 600-ml cylindrical grinding chamber filled to 80% with ZrO 2 beads (diameter=0.4–0.6 or 1.25–1.6 mm) stirred by four disk-shaped slotted blades. A pulley drive system allows four different speeds of rotation to be used (2125, 3675, 3385 and 4435 rpm).
METHODOLOGY TO PREDICT PRODUCT SIZE DISTRIBUTION OF A ...
methodology to predict the product size distribution of a vertical stirred grinding mill using the population balance model. Initially, detailed experimentation was carried out in a Bond Ball Mill and the breakage and selection functions were determined for the aggregate material tested. After collection of the breakage parameters, it was possible to predict the product size distribution as a function of …

Dry grinding of talc in a stirred ball mill. In low speed vertical stirred mills ... The effect of stirrer tip speed for the pin mill is presented in Figure 7 ... and media size (b) on pin mill grinding product.
Prediction of Product Size Distribution of a …
This work presents a hypothesis of a methodology to predict the product size distribution of a vertical stirred mill using a Bond ball mill. The Population Balance Model (PBM) was used to empirically analyze the performance of a vertical mill and a Bond ball mill. The breakage parameters obtained for both grinding mills are compared to determine the possibility of predicting the product size distribution of a vertical mill …

Predicting the product particle size distribution …
The mineral processing industry has seen an increased use of vertical stirred mills, owing to the inefficiency of ball mills for fine grind applications. The difficulty encountered in fine grinding is the increased resistance to comminute small particles compared to coarse particles. As a result, increased energy inputs are necessary to raise the number of collisional events in a mill ...

The effect of ball size distribution increased with increasing mill filling and for the mill filling of 35%, the ball size distribution had the maximum effect on the power draw. When the mill ...
Stirred Milling Technology – A New Concept in Fine Grinding
al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 µm.
Comparing ball and vertical mills performance: An ...
Many authors claim that stirred mills have better performance than conventional grinding (Pena, 1992; ... was difficult to compare directly the product sizes distributions from the ball mills and from the vertical one. By general observation, it can be said that, since the fresh feed for each mill is reasonably similar, so are the product curves, as be seen in Figure 6. Therefore it was used ...
