Oct 01, 2002 For comparison, when the model of Whiten and White (1979) is used for simulation of the behaviour of short-head cone crushers, the values for φ, m and l are often fixed to 0.2, 0.5 and 2.5 respectively. A greater value for the fine fraction φ in our case reflects the well-known fact that the product issued from impact crushing contains more fines than that obtained with cone or jaw crushers.

In this paper we develop a performance model for impact crushers. The product size distribution is obtained as a function of the crusher’s rotor radius and angular velocity, the feed rate and the feed size distribution. The model is based on the standard matrix formulation that includes classification and breakage matrices.

Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill

and with the decreased grain size, the necessary ball size also decreases (Olejnik, 2010; 2011). For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

One can increase the weight of the charge by increasing the number of balls or by using a ball material of high density. Optimum grinding conditions are obtained when the volume of the balls is equal to 50 percent that of the ball mill.
