Grinding mill with securing frame
A grinding mill for pulverizing material includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish in which the material is disposed, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the grinding mill can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.
1. A grinding mill system for pulverizing material, comprising:
a dish including a base and a lid;
a pulverizing agent disposed within the base;
a platform having an upper surface and defining a recess having a floor, the recess configured to seat the dish in which the material and the pulverizing agent are disposed; and
a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform.
2. The grinding mill system of claim 1 , further comprising a motor configured to cause oscillation of the platform and the movable securing frame.
3. The grinding mill system of claim 2 , further comprising a counterweight configured to be rotated by the motor to counterbalance the oscillation of the platform and the movable securing frame.
4. The grinding mill system of claim 3 , further comprising an annular disc to which the counterweight is secured.
5. The grinding mill system of claim 1 , further comprising a housing rigidly secured to the platform.
6. The grinding mill system of claim 5 , wherein the housing is disposed above the upper surface of the platform.
7. The grinding mill system of claim 6 , further comprising an actuator and a rod connected to an upper support of the frame, wherein the actuator is configured to translate the rod to move the frame with respect to the housing.
8. The grinding mill system of claim 1 , wherein the lift support is movable within an opening defined by the floor of the recess.
9. The grinding mill system of claim 1 , further comprising a plurality of pillars supporting the platform, wherein each of the plurality of pillars is made of a rubber material.
10. The grinding mill system of claim 1 , further comprising a U-shaped collar disposed on the upper surface of the platform to guide the dish toward the recess.
11. A grinding mill system for pulverizing material, comprising:
a dish including a base and a lid;
a pulverizing agent disposed within the base;
a platform having an upper surface and defining a recess having a floor, the recess configured to seat the dish in which the material and the pulverizing agent are disposed; and
a movable securing frame having an upper support with a clamping surface and a lower support with a lift surface, the frame being movably connected with the platform along a path defining:
a first position in which the lift surface of the lower support is beneath the floor of the recess and the clamping surface is in contact with the dish to clamp the dish between the clamping surface and the floor of the recess; and
a second position in which the lift surface of the lower support is coplanar with the upper surface of the platform.
12. The grinding mill system of claim 11 , wherein a height of the lower support is at least as tall as a height of the platform.
13. The grinding mill system of claim 11 , wherein the upper support of the frame has a boss extending downward from the clamping surface, the boss being cup-shaped and defining a depression that faces downward toward the lower support.
14. The grinding mill system of claim 13 , wherein the lid of the dish has an upper surface and a knob extending upward from the upper surface.
15. The grinding mill system of claim 11 , further comprising an actuator and a rod connected to the frame, wherein the actuator is configured to translate the rod to move the frame with respect to the platform.
16. A method of using a grinding mill system for pulverizing material, comprising the steps of:
placing a dish containing a pulverizing agent and materials to be pulverized above a recess defined by an upper surface of a platform, including seating the dish on an upper surface of a lift support of a movable securing frame that is movably connected with the platform;
lowering the frame with respect to the platform to lower the upper surface of the lift support through the recess to a location beneath a floor of the recess, thereby seating the dish within the recess; and
oscillating the platform, the movable securing frame, and the dish.
17. The method of claim 16 , wherein the step of oscillating further includes rotating a counterweight to counterbalance the oscillation of the platform, the movable securing frame, and the dish.
18. The method of claim 16 , further comprising a step of lowering the frame further with respect to the platform to engage a boss extending downward from a lower surface of an upper support of the frame with the dish.
19. The method of claim 16 , further comprising a step of clamping the dish between an upper support of the frame and the floor of the recess of the platform by lowering the frame further with respect to the platform.
20. The method of claim 16 , further comprising a step of raising the frame with respect to the platform to raise the upper surface of the lift support through the recess to a location coplanar with the upper surface of the platform, thereby raising the dish out of the recess.
