Motor Grinding


The Mortar Grinder Model ORB100 is used to reproducibly grind, homogenize and mix a wide range of solid materials in dry / wet or cryogenic condition. The material to be processed falls into the Pulverizing area between Mortar and Pestle by top feeding via the opening which is at the inlet cover. The material is then pulverized and mixed between the Mortar inner surface area and the bottom of the pestle. In order to match the necessary top pressure with the requested end fineness and the breaking behaviour of the sample to be prepared the ORB100 is equipped with and adjustable Top Pressure Mechanism with scale and a variable speed setting 50-130 rpm and a flexible scraper setting.

Only due to the combination of this 3 key adjustment features a wide range of sample preparation tasks can be reached.

No other grinding system is more easy to clean then the ORB100 Mortar Grinder.
When the grinding process is finished the Mortar and Pestle can be taken out with a bayonet lock in order to perform a quick cleaning of the grinding tools.
