Grindometer which consists of two metal troughs with numerical marks is a device to measure the fineness of grind during the manufacture of pigmented products including chocolates, paint and other similar products. It is a very useful tool as a guide to dispersion and the advantages of this method is that it takes only a matter of seconds to make an assessment, which is important during pigment grinding, yet produce numerical results which can be recorded and reproduced for comparison.
The grindometer is a device widely used to help gauge the particle size of suspensions, usually inks for example those utilized in printing, or paints. See more.
It is made up of a metal block with a channel of variable depth machined directly into it, beginning at a convenient depth for the special type of suspension to be gauged, and changing to shallower right until it finishes flush with the block's surface.
The depth of the groove is scarred off on a regressive scale of measurement next to it. The suspension to be checked on is poured into the deep end of the groove, and scratched in the direction of the low end with a flat steel scraper. At the point in which the range of the groove equates to the biggest particles in the suspension, problems will become noticeable.
