Mill: A mill is a homogenizer composed of a conical rotor and stator. The rotor and the stator are separated by a small clearance where the premix will flow due to shear and centrifugal forces. As the premix is gravimetrically fed into the rotor-stator assembly by a hopper, it is thrown outward towards the exit slot or holes

10.12.2017The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.

A ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked. They are characterized by a long service life and provide a reliable sealing over the life span, even when the valve is
