Description:
A method was sought that allows for coordinating the particle grinding time and the particle size in a closed milling circuit. This can be achieved by placing the input of the return flow from an end classifier at an intermediate position of the tube mill length. A simple model to estimate the efficiency of the approach is proposed. It is shown that such an optimal position exists and depends on the classifier efficiency. One of the key problems in improving the efficiency of grinding is how to match the particle size and the necessary grinding time. A model for optimizing the position of the circulating load input in a closed milling circuit with a tube mill is proposed. It is shown that such an optimum does exist and can yield a considerable gain in the circuit capacity.
