US 4,275,850 A · Plate-type paint grinding machine and its use in pigment testing

Abstract

A grinding apparatus having two mulling plates disposed horizontally in superposed relation is provided. The lower mulling plate is connected to suitable drive means for rotating the plate (the direction of rotation is reversed intermittently). The upper mulling plate is eccentrically connected to a support structure and is provided with a guide pin connected at one end to the plate and which extends at the other end through a slot in the support structure. In operation, the lower mulling plate upon rotation effects movement of the upper mulling plate about its eccentric axes, but the extent of travel of the upper mulling plate is controlled or limited by the guide pin which contacts one end or the other of the slot in the support member. The apparatus is useful for grinding pigment and paint.

Apparatus adapted for grinding which comprises a base member;

a first mulling plate disposed horizontally on said base member;
a support member connected to said base member for engaging and supporting a second mulling plate disposed horizontally and in superposed relation to said first mulling plate;
guide means disposed on said second mulling plate and operatively engaging stop means cooperatively disposed on said support member and drive means adapted upon actuation to rotate said first mulling plate thereby to rotate said second mulling plate until said guide means engage said stop means thereby to limit the movement of said second mulling plate in relation to said first mulling plate.
