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; the apparatus comprising a pump (112) for pumping a fluid, the fluid being a suspension of solid particles of the bulk laminar material, at a pressure of greater than 1 MPa, along a fluid conduit (12) and against an impact head (16) having an impact face perpendicular or substantially perpendicular to the trajectory of the incoming fluid, being the principal axis relative to the proximal end of the conduit (24) so as to form a narrow and variable gap (20) and where in the impact head is symmetric about a longitudinal axis which is in line with the principal axis and such that the symmetry allows rotation of the head. 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.

An aero acoustic processing apparatus includes an aero acoustic processing machine (10) having a cyclone chamber (12) having an inlet (14) for receiving waste to be processed and an inlet (16) for an entraining gas in the form of air. A rotational drive apparatus in the form of an electric motor (18) is coupled to a shaft (20) to which an impeller (22) is coupled rotates the impeller (22) within an impeller housing (24) to draw the air and the waste material to be processed into the cyclone chamber (12) and through an axial inlet system (26) into the impeller (22) and impeller housing (24) and to expel the processed material through the impeller housing (24) radially through a transverse outlet.

A method for manufacturing a water absorption treatment material made of a plurality of grains includes a preparing step, a pulverizing step, a core portion forming step, and a coating portion forming step. The preparing step is a step of preparing a paper powder to which water-absorbent polymers adhere, the paper powder being derived from a sanitary product. The pulverizing step is a step of pulverizing remaining polymers using a pulverizer. The core portion forming step is a step of forming a core portion constituting each of the grains The coating portion forming step is a step of forming a coating portion so as to cover the core portion, the coating portion containing the paper powder, and the remaining polymers pulverized in the pulverizing step. In the pulverizing step, the remaining polymers left in a state of adhering to the paper powder are subjected to the pulverizer.
