Trials and test series for product development and process optimisation as well as small batch productions are the ideal field of application of the Bauermeister Laboratory Roller Mill LRC 250. It is suited for the gentle size reduction of brittle to semi-hard foodstuffs, minerals, plastics, or chemical products. A gentle grinding per stage leads to the production of end products with a narrow particle size distribution and a low percentage of fines. The results achieved on the LRC can, in virtue of the same roll diameter, be directly scaled up to Bauermeister production sized Roller Mills such as the series 250.1, 250.2 and 250.3.
Milling parameters such as the grinding gap between the rolls, roll speed as well as roll differential speed are easily and infinitely adjustable. An Easy-Lock roll clamping system allows a straightforward changing of a roll in less than a minute. A wide range of available roll profiles from smooth to different corrugations round up the LRC as the perfect machine for product development as well as process optimisation. Trial grinding can be carried out with samples as small as 0,5 kg per run.
The grinding chamber and the product collecting bin are of stainless steel. The grinding process can be monitored and assessed through an acrylic glass cover plate. Each roll has a separate drive motor controlled by a frequency converter. Roll gap adjustment is carried out with a micrometre screw and can be adjusted infinitely between 0.1 and 15 mm. A simulation of multiple grinding steps with different rolls is possible.
