AN APPARATUS AND METHOD FOR SIZE REDUCTION.

摘要

The present invention provides a method for size reduction of a material comprising the steps of: feeding material through a feed assembly into a cyclone chamber, the cyclone chamber having an elongate cylindrical conduit having a frusto-conical section; adding at least one viscosity modifying agent into the cyclone chamber; and providing a cyclonic fluid stream within the cyclone chamber. The present invention also provides an apparatus for size reduction of a material. The apparatus comprises: a cyclone chamber (4) having an elongate cylindrical conduit having a frusto-conical section (4a); a device (5) for creating a cyclonic fluid stream within the cyclone chamber (4), such that the frusto-conical section (4a) of the cyclone chamber (4) terminates in an opening forming the inlet to the device; an air inlet tube (3) in fluid connection with the cyclone chamber (4) at the opposite end of the frusto-conical section (4a); and a feed assembly for feeding material into the cyclone chamber (4).
