Abstract
The invention is a centrifugal grinder. The grinder contains a rotary receptacle lower part and a stationary receptacle upper part, wherein the receptacle lower part and the receptacle upper part each have a ceramic part on opposing faces defining an opening into the grinder between the receptacle parts, and an adjustable straight gap which includes the opening provided between the ceramic parts extending radially relative to an axis of rotation of the rotary receptacle.
Claims13
A centrifugal grinder comprising:
- a rotary lower part and a stationary upper part with an inner side of the lower and upper parts defining a receptacle which receives objects to be ground and grinding particles which grind the objects during rotation of the rotary lower part;
- the rotary lower part and the stationary upper part each comprising a ceramic part on opposed faces defining an opening extending from outside the receptacle into the receptacle;
- and wherein
- the opening comprises two pairs of horizontally opposed faces with a first pair of opposed faces being radially displaced from the receptacle relative to an axis of rotation of the grinder and separated by a first distance and a second pair of opposed faces which are part of the ceramic parts terminating at the receptacle and being separated by a second distance which is less the first distance;
- and
- an adjustment mechanism which adjusts the first and second distances by moving the rotary lower part and the stationary upper part vertically relative to each other.
