An agitator mill including a grinding chamber containing grinding bodies and an agitator shaft, which revolves therein around a horizontal axis and which supports several grinding disks, which are connected thereto and which are spaced apart from one another in the direction of the horizontal axis and which move the grinding bodies, wherein grinding disks preferably in each case have slits or apertures, wherein adjacent grinding disks are arranged on the agitator shaft so that the ratio of the grinding chamber length to the radial grinding chamber height is greater than or equal to 2:3, and that the radial distance between the outer jacket surface of the grinding disks and the inner wall of the grinding container limiting the grinding chamber is more than 20% of the radial grinding chamber height.

Agitator mill

A stirring mill, including a horizontally arranged milling vessel and a stirring shaft which is arranged therein so that it can be rotationally driven are provided. The stirring shaft has a first stirring shaft section adjacent to an inlet for material to be ground, which has a smaller diameter D, and a second stirring shaft section adjacent to an outlet for material to be ground, which has a larger diameter Dand in which a separating device is formed. Bypass channels leading into the separating device are formed in the first stirring shaft section.

Stirring mill

An agitator ball mill including an in particular horizontal grinding container, which has a first end area having a grinding material inlet and a second end area having a grinding material outlet, and a method for operating an agitator ball mill. The agitator ball mill includes a shaft, which can be rotated in the grinding container or in the grinding chamber, respectively, by means of a drive unit and which is formed as agitator shaft at least in sections and which is equipped with agitator elements, as well as a separating device. The separating device includes a classifier rotor, which is arranged on the agitator shaft axially spaced apart from the grinding material outlet and has a rotatable rotor cage, as well as a screen unit, which is arranged within the rotor cage and which is fastened to the classifier rotor.

Agitator ball mill and method for operating an agitator ball mill

A separating device for a ball mill or an agitator ball mill as well as a ball mill or agitator ball mill with a separating device, wherein the ball mill or agitator ball mill includes a cylindrical grinding container with a first end opening and a second end opening, wherein the first and second end openings can be closed by a first and a second closure device, wherein a ground stock inlet is arranged in the region of the second end opening and a ground stock outlet is arranged in the region of the first end opening and wherein the separating device is assigned to the ground stock outlet. The separating device includes a plurality of first and second screen segments with screen apertures, which are arranged in an alternating manner on a frame.

Separating device for a ball mill or agitator ball mill as well as a ball mill or agitator ball mill with a separating device

A preliminary size reduction device for a ball mill or agitator ball mill and a ball mill with a preliminary size reduction device, wherein the preliminary size reduction device is disposed between a grinding stock inlet of the ball mill or agitator ball mill and a grinding chamber and includes a first size reduction mechanism constituted stationary and a second, rotationally mobile size reduction mechanism, between which a size reduction gap is formed. The first size reduction mechanism constituted stationary is a size reduction ring disposed in the grinding container.

A method for dry operation of an agitator bead mill, with a mill housing that includes a grinding chamber, in which a rotatable agitator shaft extends horizontally between an input side and an output side and in which grinding media are situated. An output gas is fed into the grinding chamber on the output side, goes together with ground grist through the separation system radially with respect to the transport direction, and thus leaves the grinding chamber together with ground grist through the separation system and onward through the product output. Also disclosed is an agitator bead mill for executing the method, such that the separation system has a static sieve with a free perforated surface that is chosen in such a way that the pass-through speed of the gas leaving the agitator mill through the separation system and the product outlet amounts approximately to 10 m/s to 30 m/s.

Method for operating an agitator bead mill and agitator bead mill therefor

A method for the introduction of auxiliary grinding bodies into an agitator ball mill and for the removal of auxiliary grinding bodies from an agitator ball mill. The auxiliary grinding bodies are transported into the agitator ball mill and out of the latter via a closed circuit by means of a hydraulic conveying medium.

Hydraulic milling ball feed and discharge for stirred ball mills

A rotary piston pump equipped with a motor having two counter-rotating rotary pistons. The two rotary pistons are housed in an oval pump housing. The two rotary pistons are arranged on a first output shaft and a second output shaft. The first output shaft and the second output shaft are driven and synchronized via at least one elastic element.

Rotary piston pump and method for operating a rotary piston pump

The agitator ball mill according to the invention for grinding dry or non-dry substances is provided with a grinding container. The grinding container is provided with an inlet for the material to be ground, a fluid inlet and a material outlet, wherein the outlet region is provided with a screen. Running in the center or in the vicinity of the center of the grinding container is an agitator shaft, on which a plurality of grinding elements are disposed. The grinding container is at least partially filled with auxiliary grinding bodies. A first cage is assigned to the inlet region of the agitator ball mill and a second cage to the outlet region.

Stirring ball mill

The invention relates to a method for the comminuting of natural or synthetic mineral products having a size of 10 nm to 30 mm, which are obtained from the upstream process in pre-comminuted form for example in a roller mill for inter-particle comminution, wherein these solids are further comminuted in a working process initially dry then wetted with liquid and in this liquid are comminuted so as to obtain a suspension that can be pumped, which suspension is subsequently ground to the desired final fineness by means of agitating mills.
