The Stones are made only of natural materials such as emery and flint and a type of magnesite is used as binding, They are solid and have an excellent resistance which means a long duration.
Stone Mill MB250 is built on strong welded stainless steel frame, resulting in elevated robustness. The hopper has a load capacity of about 20 kg and granules fall inside through an adjustable system. The fineness degree of the flour can be adjusted using a wheel that regulates the distance between the stones
(nearer or larger). The upper stone is fixed, while the lower one is rolling and rotates by means of trapezoidal transmission belts, driven by a 1,8 KW electric motor which can be supplied single phase 230 Volts or three phase 400 Volts. The rolling stone is equipped with two small brushes to make easier the cleaning and the emptying of the grinding chamber.
