  • Publication number: 20230294050
    Abstract: A high pressure homogenizer for flowable substances charged with particles, having a high pressure chamber and a homogenizer unit that is located fluidically downstream thereof and, by swirling, expands the fluid to be homogenized which has previously been brought to a pressure of more than 500 bar in the high pressure chamber, and a plunger pump associated with the homogenizer unit, the plunger of which plunger pump pressurizes the high pressure chamber, wherein the high pressure homogenizer has a low pressure chamber which surrounds the plunger shaft to cool the plunger and which has an operating pressure of PN?25 bar, wherein the low pressure chamber and the high pressure chamber are separated from each other by a seal which is penetrated by the plunger, the seal being a throttle gap which is formed between the plunger shaft and a bushing that does not contact the plunger shaft, the ratio S/L of the length to the radial annular gap height of the throttle gap being ?0.0015.

  • Patent number: 10279353
    Abstract: A mill and operating method for using grinding bodies for grinding a grinding stock. Grinding bodies that have passed through the through the product outlet enter an upwardly inclined discharge pipe from where, when the grinding body mill is at a standstill, the grinding bodies are directed out of the discharge pipe through the product outlet into a rotor body of the separating device. When operation of the grinding body mill is resumed, the grinding bodies are conveyed back into the grinding chamber owing to the rotation of the rotor body.
