XHY-52 Laboratory Muller Grinder

Muller Laboratory Grinder is a sturdy machine, enabling optimal and perfectly reproducible grinding and dispersion to be obtained in the laboratory.  It has been designed to grind and discharge small amounts of raw materials for paint and varnish.

ASTM D 387, ASTM D 332-B,ISO 8780-5,ISO 787/16

This unit consists of a steel frame holding two ground-glass plates, the lower of which is motor driven.  A LCD counter can help operator register the total number of revolutions and automatically stops the motor once the user’s defined number of revolutions has been met. Furthermore, it also can show the total after each test cycle.

An amount of raw material is spread over a limited area of the lower glass plate. The mixture is ground in successive stages, for example 50 revolutions each, at a pressure, of 445N. Between each stage, the mixture should be redistributed within the limited area.

The Muller Laboratory Grinder is suitable for preparing dispersions for testing mass color and tinting strength and preparing small samples for use in the quality control of pigments
