Abstract: A spice or peppercorn grinder including a cylinder body; an L-grooved barrel in the cylinder body; a top cap connected to a pressure drum slidably mounted in the L-grooved barrel, a rotatable ?-shaped open-end long tube provided in a lower space of the pressure drum and engaged with a screw-shaped long axis assembly provided rotatably in the L-grooved barrel, so that when the ?-shaped open-end long tube moves downwardly with the pressure drum, the screw-shaped long axis is caused to rotate in a certain direction, the other end of the screw-shaped long axis assembly being provided with a pinion; a compression spring being provided between the seat of the L-grooved barrel and the bottom of the pressure drum; a gear-toothed ring transmission mechanism being provided beneath the L-grooved barrel; a grinding plate assembly being provided on the cylinder bottom and being driven by the gear reduction apparatus to rotate in one direction to grind spices or peppercorns.

Abstract: A spice or peppercorn grinder including a cylinder body; an L-grooved barrel in the cylinder body; a top cap connected to a pressure drum slidably mounted in the L-grooved barrel, a rotatable ∞-shaped open-end long tube provided in a lower space of the pressure drum and engaged with a screw-shaped long axis assembly provided rotatably in the L-grooved barrel, so that when the ∞-shaped open-end long tube moves downwardly with the pressure drum, the screw-shaped long axis is caused to rotate in a certain direction, the other end of the screw-shaped long axis assembly being provided with a pinion; a compression spring being provided between the seat of the L-grooved barrel and the bottom of the pressure drum; a gear-toothed ring transmission mechanism being provided beneath the L-grooved barrel; a grinding plate assembly being provided on the cylinder bottom and being driven by the gear reduction apparatus to rotate in one direction to grind spices or peppercorns.
