ABSTRACT:
A hand-held pulverizer which is compact and efficient to use is provided to pulverize or grind a material. A cover is removably attached to a hollow cylindrical casing containing a mesh screen. A grinder disc is securely affixed to one end of a shaft rotatably mounted in the cover and is in frictional contact with the mesh screen. A handle attached to the shaft above the cover permits the shaft and disc to be rotated, grinding or pulverizing the material placed on the screen beneath the disc. A collecting plate attached to the bottom of the cylindrical casing receives the pulverized material falling through the screen.
