ABSTRACT:
A pulverizing disc 10 is disclosed which comprises a main body 11 of a generally cylindrical shape with a circumferential wall 12, lower surface 13 and upper surface 14. The main body 11 is integrally formed with a second body 14 which is also of generally cylindrical shape and which is mounted centrically upon the upper surface 14. The second body 15 extends from one side of the main body 11 to a position beyond a central axis 16 of the main body 11. An aperture 17 is formed through the disc 10 along the central axis 16. An upper surface 19 of the second body 15 is bevelled downwardly in the radial direction from axis 16 to form a central high region 18 around the perimeter aperture 17. The bottom surface of the first body 11 can be formed with a flute 23 which extends radially from aperture 17 to circumferential wall 12 of the first body 11. A valve 24 disposed in aperture 17 can be used to control the direction of fluid flow so that fluid can flow only from above the disc 10 through aperture 17 to below the disc 10. This allows pressure equalization across the disc 10 and assists in preventing the stalling of the disc 10 when in use.
