Abstract
Disclosed is a method of mechanically crushing microalgae cells of the genus Chlorella at an industrial scale, the mechanical crushing being carried out in a horizontal ball mill system. In the method, the balls have an apparent density of between 2 and 3.5 kg/l, the filling rate of the crushing chamber is greater than or equal to 80%, and preferably greater than or equal to 85%, and the mechanical crushing is carried out continuously by a series of successive passes.
