A horizontally fed disk grinding system includes a tray coupled to a trailer for receiving bulk material. The system further includes a grind hub coupled to the trailer and a cutter disk coupled to the grind hub. The grind hub is structured to rotate about a grind hub axis and the cutter disk is structured to rotate about a cutter disk axis and about the grind hub axis. A grind ring is coupled to the trailer and is structured to slide to engage the grind hub during use. A plurality of plates are coupled to the tray and structured to oscillate to feed material from the tray to the grind hub and the cutter disk, where the material is reduced to particulate form. The grind hub further includes an outlet and a conveyor rotatably coupled to the trailer to convey the particulate material away from the outlet to a selected location.

A device for treating a web of fibrous material, the device comprising: a sensor for detecting vibrations; a multi-part housing including a cover; and a plurality of fiber treatment tools arranged inside the multi-part housing, the plurality of fiber treatment tools including a plurality of treatment profiles facing one another, being arranged spaced apart from each other so as to form at least one treatment gap with the plurality of treatment profiles, and being mounted rotatably relative to one another, at least one of the plurality of fiber treatment tools being mounted axially movable in the multi-part housing so as to be configured for adjusting a width of the at least one treatment gap between the plurality of treatment profiles facing each other, at least one of the plurality of fiber treatment tools being supported by a part of the multi-part housing, the sensor being arranged on the multi-part housing.

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.

A device for comminuting ore and/or slag is contemplated. The device may be comprising an ore feeding unit for feeding ore which is to be comminuted to a first pulverizer, said first pulverizer being composed of at least of two comminuting elements which can be moved relative to each other, said elements forming together at least one comminuting space for the ore which is to be comminuted, such that, by a relative movement in the form of a rotation about the rotational axis of at least one of the two comminuting elements the ore which is to be comminuted is at least partially pulverized. One or more accelerating elements, in particular protrusions, are provided on at least one of the comminuting elements, said accelerating elements being arranged in particular on the end face of at least 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. An intermediate space is provided between the two comminuting elements and/or in at least one of the two comminuting elements, through which space the pulverized ore, during the rotation, is transported from the center of rotation toward the outside and away from the two comminuting elements. At least one of the two comminuting elements is operatively connected to a hydraulic spring pressure device, said hydraulic spring pressure device being designed such that the comminuting element to which it is operatively connected is variably resiliently mounted in the direction of the other comminuting element depending on an adjustable hydraulic spring pressure control unit.

A method and system for of cooling a disc mill having a rotating disc blade is disclosed. A disc mill may have a first and second material outlet positioned generally along tangents to the rotating disc blade. Air may be drawn through the first and second material outlets. A disc mill may include first and second air inlets positioned generally along tangents to the rotating disc blade. The first and second inlets may direct air streams to cool a first and second portion of the rotating disc blade and pulverized material.

The subject of the present invention is a method for processing electrical and electronic components in order to recover valuable materials, such as the metals contained in printed circuit boards. According to this method, the electrical and electronic components are pre-shredded mechanically and then mixed with a liquid before they undergo wet milling (5).
