摘要： A refining disc (6) in a defibrator (1) for refining fibrous material is provided with non-central openings (11) for allowing steam developed in the refining space (2) during refining to flow from the front side to the backside of the refining disc (6), where the front side is facing a second refining disc (5) and the backside is facing away from the second refining disc (5). The refining disc (6) also comprises a central hole (12) for allowing steam (8b) to flow from the backside to the front side at the rotational center of the refining disc (6), and escape from the defibrator (1) backwards through the feed screw (3a) without passing through the fibrous material (7) being refined in the refining space (2).

摘要： The invention regards to a device for comminuting ore and/or slag, which comprises an ore feed unit for feeding ore to be comminuted to a first comminuting means. The first comminuting means being composed of at least two comminuting elements that can be moved relative to each other, which elements form at least one comminuting space for the ore to be comminuted with each other such that, by a relative movement in the form of a rotation around the rotational axis of at least one of the two comminuting elements. The ore to be comminuted is pulverised in that one or more accelerating elements, in particular protrusions, are provided on at least one of the comminuting elements. The accelerating elements being arranged in particular on the end face of one of the two comminuting elements and accelerating and comminuting the ore to be comminuted by the rotation of one of the two comminuting elements. Between the two comminuting elements and/or in at least one of the two comminuting elements, an intermediate space is provided through which during the rotation the pulverised ore can be conveyed away outwards from the centre of the rotation and from the two comminuting elements. An outlet unit for outletting ore comminuted by the first comminuting means is provided which is connected to the intermediate space. The outlet unit is connected with a separating means, by means of which the comminuted ore is separated into two portions. A first portion of the comminuted ore comprises a particle size, which is essentially larger as a predefined particle size of a second portion of comminuted ore. The first portion of the comminuted ore is guided to the first comminuting means or to a second comminuting means and the second portion of the comminuted ore is guided to a floation means.

摘要： A refiner is disclosed comprising relatively rotatable inner and outer conical refining blades. The refining blades are coaxially arranged around a symmetry axis and are provided with first bars and second bars, respectively, for the grinding of fibrous material. The inner conical refining blade or any of the first bars of the inner conical refining blade extend further along the symmetry axis, in the direction of the tapering of the inner and outer conical refining blades, than the outer conical refining blade or any of the second bars of the counter conical refining blade.

摘要： A device for grinding coffee beans includes a body provided with a vertical hopper for the entry of the coffee beans and a separate vertical outlet for the ground coffee, which are mutually connected by way of a horizontal seat within which a shaft is associated axially and rotatably. A first grinder is keyed to the shaft and interacts with a facing second grinder. These grinders cooperate with elements adapted to allow a first, micro-adjustment and a second, macro-adjustment of the grinding as a function of the type of coffee beans selected.

摘要： A vertical and horizontal mills and discs therefor for grinding particles to submicron size. The mills include two overlapping vertical barrels. Each barrel has a shaft and a plurality of circular discs attached to the shaft disposed in each barrel for grinding materials to submicron size. The discs have an open mesh design provided by overlapping rectangular blades. Each blade has at least two opposing walls orthogonal to a plane defined by the disc. Each disc on one shaft overlaps a disc on the other shaft by from 30 to 45% of the diameter of the discs. An inlet is provided for feeding material to be ground by the mill to the overlapped portion of the discs. An outlet is disposed at an end of the mill opposite the inlet for removing ground material from the mill.

摘要： A method is disclosed for producing, only with mechanical treatment, high-quality rice flour having a rounded particle shape, which is equivalent to fine flour obtained by using enzymes, has characteristics close to the characteristics of wheat flour, and is suitable for production of bread, cakes, noodles, and the like. In order to attain the object, a method for producing rice flour includes: providing primary crushing material rice subjected to soaking and adjustment of moisture content with a disintegrating and sizing device, fine grinding the primary crushed rice with an air mill, and then drying the fine ground rice with an air flow dryer.
