Pulverizer Ring Mills
High-precision laboratory and process equipment for measuring abrasion resistance, impact strength, hardness, and grindability according to Bond testing methods.
Pulverizer ring mills are precision grinding machines used to reduce material particle size for laboratory analysis, material characterization, quality control, and process optimization.
These machines are designed for consistent, repeatable results on ores, minerals, chemicals, bulk solids and powders.
The LAARMANN ring mills are essential for all applications which demand the grinding of hard, brittle and fibrous material down to analytical end fineness.
With a LAARMANN Ring Mill you put the sample together with a disc or a set of rings and roller in a bowl to bring it all together into 3-dimensional vibrations.
Inside the bowls the sample will be ground and homogenized by high pressure, impact and friction rapidly down to analytical end fineness.
Typically samples are ground to 90-95% < 75μm in approximately 3 minutes. Exact time and end fineness depends on the sample characteristics
