In previous studies, the analysis of ball mill ° operating parameters and their effects on breakage phenomena has been limited to homogeneous materials. Though these ß studies have proven to be an asset in predictions of product size distributions and mill scale—up, they have not addressed the primary role of grinding, i.e. liberation. I

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.

The continuous tumbling ball mills do not have moving, internal mixing elements; so, recirculation rate between adjacent cells is expected to be rather low as compared with the bulk axial transport rate of the material, thus justifying the lower value of the fitted R.

Predictions for fineness thus obtained was indeed promising. This paper is organized as follows. Section 1 gives a general introduction of the cement ball mill, its quality parameter-the blaine and soft-sensing techniques available in literature to predict it.

The ball mill has a length of 11.6 m and a diameter of 3.8 m, and it has a rotational speed of 15.4 rpm. The drive power is 2,400 kW, and the grinding capacity is 60 t/h. One of the most important quality-relevant parameters in cement grinding is the fineness of the product.

This paper describes the design and implementation of a soft sensor based on a backpropagation neural network model to predict the cement fineness online in a ball mill. The input variables of these models were selected by studying the cement grinding process, applying Spearman's rank correlation, and the mutual information (MI) algorithm.

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 ward. However, in recent studies, this appears not to be

The specific surface, or Blaine fine-ness, indicates the extent to which the clinker and gypsum were pulverized to make the cement. The higher the Blaine, the more finely ground the ce-ment. Finer cements react faster with mixing water to develop higher early ...

fineness are available on the market, they are expensive and, due to their exposition to fine particles from the ball mill, they require constant cleaning and maintenance [6]. In recent years, some studies have been conducted to develop models capable of estimating the cement particle size for the ball and vertical mills [7]–[9].

The diameter of a ball mill has a great influence on the power consumption of the mill and thus on the possible production output. This is because the ratio of the diameter to the grinding path length determines the residence time of the material in the mill and thus the theoretically achievable fineness of the material at the discharge.
