Grinding apparatus

A grinding assembly configured for grinding a substance, the grinding assembly comprising:

• a first component comprising:
• a first side disposed opposite a second side;
• and
• a wall located around a periphery of and extending away from the second side;
• and
• a first set of protrusions extending away from the second side;
• a second component comprising:
• a first side disposed opposite a second side;
• a wall located around a periphery of and extending away from the second side to create a concave portion;
• and
• a first threaded portion disposed on a periphery of the wall;
• and,
• a chamber component comprising:
• a body portion comprising a first side disposed opposite a second side, the second side comprising a second threaded portion configured to interact with the first threaded portion of the second component to affix the second component to the chamber component;
• a wall located around a periphery of a planar surface and extending away from the first side to create a chamber, wherein the chamber of the chamber component having a magnetic receiving portion, the magnetic receiving portion having an end connected to a substantially central portion of the planar surface of the body portion located opposite another end configured to be connected to at least a portion of the first component, the magnetic receiving portion has a radiused guide wall comprising at least one curved surface traversing a length of the receiving portion;
• wherein, the chamber component having a second set of protrusions;
• and,
• at least one opening disposed through the planar surface of the chamber, wherein at least one curved surface of the radiused guide wall of the magnetic receiving portion abuts an outer perimeter edge of at least one opening of the at least one opening of the planar surface of the chamber.
