BERTOLI BMC Colloidal Mills

The Bertoli Colloidal Mills – Model BMC is equipped with a cooling mechanical seal made of tungsten carbide, ensuring durability and optimal performance. Its rotor and stator are constructed from AISI 630 stainless steel, offering excellent wear resistance. The mill features a painted iron frame and operates with a noise level below 85 dBa for a quieter working environment. It includes flange and counterflange connections for efficient product inlet and outlet. Powered by an electric motor compatible with 220/380/440V, 50/60Hz, 2 poles, the mill also integrates a Siemens KTP 400 PLC automation system for precise grinding regulation.
