Disclosed is a vibrating material sorting screen with a substantially variable tilt angle and a tilt angle measuring device where the screen has a gear box which is horizontal when the screen is horizontal and inclined when the screen is inclined and further where the gear box has a plurality of oil level sensors or indicators therein which are sized, placed and configured to provide proper oil volume while the screen is oriented horizontally or at various inclines.

A system and method for coffee bean processing that includes a bean refinement chute with a bean grind inlet and a refined grind outlet; a filter system integrated into at least one surface within the chute; a vibration system operable in an active state that agitates bean grinds during progression from the bean grind inlet to the refined grind outlet; a refined grind chamber positioned adjacent to the refined grind outlet and thereby collects refined grinds; and a filtered grind chamber positioned beneath the filter system and thereby collects filtered grinds.

A system and method for separating mixed materials employing an angled screen that is moved through a vertically oriented circular path by a single drive element.

A powder distributing device for preparing sheet-shaped magnets and a powder distributing method thereof are provided. The powder distributing device includes a mold, a powder feeding mechanism, and a vibrating mechanism. The mold includes a mold body and a screen disposed above the mold and connected to the mold body. The screen sifts magnetic powder into at least one mold cavity of the mold body. The powder feeding mechanism feeds the magnetic powder to the screen. The vibrating mechanism is connected to the mold body The vibrating mechanism drives the mold body and the screen to vibrate together, so that the magnetic powder on the screen is evenly sifted into the mold body and filled to a predetermined density, which improves uniformity of powder distribution in the at least one mold cavity during a molding process, thereby improving performance and consistency of the sheet-shaped magnets.

A vibrating screen for screening aggregates and/or soils. The screen includes a body (1), a chute shaped stationary screening deck (6), which is fixed to the body (1) by its opposite ends. The stationary screening deck includes stationary screening flat bars (8), which form first screening slots (8a) between them, and which have a curved shape corresponding to the shape of the stationary screening deck (6). The screen further includes a chute shaped vibrating screening deck (7), which is supported to the body by eccentric shafts (2). The vibrating screening deck (7) is arranged to be vibrated by machine power by rotating the eccentric shafts (2) synchronously with each other, thereby each point of the screening deck (6, 7) is in revolving motion continuously in the same rotating direction along a circular path when the eccentric shafts (2) rotating. The vibrating screening deck (7) comprises vibrating flat bars (9), which form second screening slots (7a) between them and whose curved shape corresponds to the chute shape of the vibrating screening deck. The vibrating flat bars (9) are located in the first screening slots (8a), and the screening decks (6,7) are positioned at such a height level in relative to each other that during one cycle the vibrating flat bars (9) rise partly above a screening surface formed by upper edges of the stationary screening flat bars (8) at different sections of the stationary screening deck (6) one after another and at different times.

A vibration monitoring system comprises sensor units that include a vibration sensor and which are locatable on an apparatus to be monitored at a respective different location. Each sensor unit is operable to take vibration measurements using its vibration sensor. The system obtains synchronized vibration measurement data for each sensor unit, and calculates a difference between the respective vibration measurement data for each sensor unit and nominal vibration data to obtain respective non-nominal vibration data for each sensor unit. The system renders to a user a visualisation, such as an animation, of the non-nominal vibration data for each sensor unit, which facilitates identification of undesirable operating modes or other undesirable conditions of the apparatus.

Tensioner systems, methods and apparatus are described for tensioning drive belts of vibratory screens.

A belt or chain driven mineral material processing device vibrator. The vibrator includes a vibrator shaft drive wheel configured to reside at least partially in a radial direction around a bearing of a vibrator shaft that extends through a device frame of a mineral material processing device. An eccentric is configured to be mounted to the vibrator shaft so that the eccentric extends in axial direction of the vibrator shaft beyond the vibrator shaft drive wheel outwards of the device frame. A method for vibrating a mineral material processing device by a belt or chain, a method for producing a belt or chain driven mineral material processing device vibrator, a method for controlling a belt or chain driven mineral material processing device vibrator, and a mobile mineral material processing plant including the mineral material processing device vibrator are also disclosed.
