摘要： The invention relates to a method and a colloidal mixer for colloidal processing of a slurry, in particular processing of construction materials, with a colloidal mixer, in which at least one liquid is introduced into a mixing trough, at the lower region of which is arranged an outlet opening with a mixing device having a mixing rotor, which is driven in rotation.
According to the invention, the at least one pulverulent solid component is introduced into the mixing trough, the at least one liquid mixed with the at least one pulverulent solid component is induced to flow by the rotatingly driven mixing rotor and is discharged from the mixing trough through the outlet opening, wherein the mixture is led back again for a certain time via a backflow line into an upper region of the mixing trough for further mixing and, after a desired mixing state has been attained, the mixture is discharged as a finished slurry from the outlet opening by means of a discharge line.
According to the invention, it is provided that air is incorporated into the at least one liquid and/or the mixture in a targeted manner in a finely dispersed form, wherein a relative density of the liquid, or of the mixture, is reduced.-

摘要： The invention relates to a device for clearing a helix gap of an auger, comprising a retainer for holding the device on a mast of a drill, a guide tube which surrounds the auger in portions and is mounted on the retainer, and a clearing element which engages in the helix gap and is mounted on the retainer so as to be freely rotatable about the drilling axis. According to the invention it is provided for the guide tube to be mounted on the retainer so as to be freely rotatable about the drilling axis, for the clearing element to be firmly attached to the rotatably mounted guide tube, for the guide tube to be axially fixed in the direction of the drilling axis, for the purpose of clearing, and for the clearing element, together with the guide tube, to be able to be caused to rotate about the drilling axis by means of a pulling procedure of the auger for the purpose of clearing the auger. The invention further relates to a method for making a drilled hole in the ground using a drill, wherein the device according to the invention is used.
