fluidised bed opposed jet mills. The wear to the mill can be kept under control by taking special measures, and products with no iron contamination can also be produced, e.g. by using ceramic components. Because comminution in a gas jet rules out the inevitable heating of the product known from mechanical mills, jet mills are
