Assignee: TORXX KINETIC PULVERIZER LIMITED
Field: Chemical engineering (Chemistry)
Classification: CPC B | IPC B

Claim 24:
25. A pulverizer comprising:
a housing having top and bottom ends, the housing further having an inlet located towards the top end for receiving input material to comminute and an outlet located towards the bottom end for discharging pulverized input material from the housing, the housing including a housing sidewall extending between the top and bottom ends and defining an interior chamber, the housing having a central housing axis;
an airflow generator disposed in the interior chamber for generating a circular airflow revolving about the central housing axis with particles of the input material in suspension in the airflow; and
at least one airflow deflector extending inwardly from the housing sidewall for deflecting the airflow generated by the airflow generator so as to form at least two vortices within the interior chamber, wherein adjacent ones of the at least two vortices overlap such that input material particles in suspension in the adjacent ones of the at least two vortices collide with each other to be thereby pulverized;
wherein the at least one airflow deflector comprises a flow facing deflecting surface extending away from the housing sidewall and inwardly into the interior chamber and an opposite deflecting surface extending away from the housing sidewall and inwardly into the interior chamber, the flow facing deflecting surface and the opposite deflecting surface converging towards each other and meeting at an apex spaced inwardly from the housing sidewall, wherein the at least one airflow deflector extends continuously from the top end to the bottom end; and
wherein the apex of the at least one airflow deflector is spaced apart from a tip of the airflow generator by a clearance space.
