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

Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
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.
particular cement. Typically, a mill test reports six physical characteristics. 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 ...

Practical 1: Title: Ball Milling Objective: To grind the coarse salt to a smaller size by using a ball mill and to obtain the particle size distribution of the initial and the sieved final mixture. Introduction: 'Ball milling is a method used to break down the solids to smaller sizes or into a powder. A…
Product fineness required The user can study the effect of all the above operating conditions on the performance of the mill circuit. The companion packages CLASANAL and SIZEANAL would be useful along with BMSIMUL for analysis of classifier operation and predicting the particle size distribution of powders at different locations respectively.
Discussion A size-energy model is applied in this study for predicting the product size distributions from a stirred ball mill. It provides an excellent fit to the experimental results. The model has two parameters which are de- termined experimentally; this is similar to the population balance model.
The output achieved by a ball mill system varies with the mill power, the fineness of the product and the hardness of the clinker. A typical general purpose Portland cement of fineness (specific surface) 340 m².kg -1 ground on an efficient closed-circuit ball mill system requires around 32 kWh per tonne, so a 10 MW mill would produce 313 ...
