Muller Laboratory 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.

This unit consists of a steel frame holding two ground-glass plates, the lower of which is motor driven.  A LCD screen can help operator set 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.

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

It can be used in accordance with ASTM D 387. ASTM D 332-B,ISO 8780-5.ISO 787/16.

I. Definition and Working Principle

Digital Grinding Machine is a laboratory equipment that uses mechanical force to crush, mix, and grind samples. Its core working principle utilizes rotational or vibrational forces to enable sample refinement through collisions and friction between grinding media (e.g., agate beads, glass beads, stainless steel beads).

Equipped with digital display and control system for precise parameter settings (e.g., grinding time, speed) and real-time monitoring.

II. Key Features
