Abstract
This invention relates to the art of methods and apparatuses for grinding various materials into smaller particles; particularly, to those known in the art as pulverizing systems and devices. This invention provides methods and apparatuses for an improved disc mill assembly that utilizes a tapered flywheel and water jacket in conjunction with planar grinding disk cutting devices to create a tapered grinding channel.
Claims11
A disc mill assembly for a pulverizing apparatus, comprising:
- a housing;
- a flywheel received in the housing and adapted for being operatively secured to an associated rotating spindle, the flywheel comprising a generally circular disc having:
- a lower planar side;
- an upper grinding disk attachment side having at least two raised concentric mating members with sloped surfaces;
- an annular outer wall extending from the lower planar side to the upper grinding disk attachment side;
- and
- an inner wall extending from the lower planar side to the upper grinding disk attachment side and defining a central flywheel opening adapted to receive at least a portion of the associated rotating spindle;
- wherein the two raised mating members with sloped surfaces comprise an outer mating member and an inner mating member;
- wherein the outer mating member and inner mating member have different heights;
- and
- wherein the sloped surfaces are both at an angle between about 0.5° and 1.5°.
