Abstract
The present invention provides an apparatus for the production of Graphene and similar atomic scale laminar materials by the delamination of a bulk laminar material, such as graphite. This apparatus provides prolonged head life and avoids catastrophic head wear in an isolated region. Overall product quality over time is better maintained. Also, the benefit of a self-unblocking delamination apparatus can be achieved whilst maintaining high product quality and consistency. Relatively small variation in gap size being sufficient to avoid blockage, such as occurs by the aggregation of large particles or groups of particles in the high shear gap used for delamination.
