Mortar Grinder

The Mortar Grinder can mix and homogenize powders, suspension and pastes, even for samples with high viscosity. The MORTAR GRINDER is suitable for the proper and reproducible sample preparation to analytical fineness.
The sample grinder substitutes cumbersome hand mortars by a high performance drive with electronic control. The grinding set can be cooled and heated and is very easy to clean. Grinding sets of various material qualities are available which can be exchanged easily for optimum adaptation to various grinding tasks.

FUNCTIONAL PRINCIPLE

The Mortar Grinder comminutes, mixes and triturates by pressure and friction. The function of the scraper is to feed the sample material into the area between the mortar and pestle. This forced feed ensures that the whole of the sample is continuously subjected to the grinding and trituration process and is also intensively mixed.
The grinder pestle is not located in the center of the mortar but is offset; contact with the rotating mortar and the sample causes it to rotate automatically. The necessary grinding pressure is achieved by the weight of the pestle itself combined with the adjustable spring pressure acting on its axis.
