Publication number: 20180078942Abstract: A vertical roll mill may include a grinding plate, a grinding roll, a nozzle ring that horizontally surrounds the grinding plate, an air feed apparatus disposed under the nozzle ring, a discharge element disposed below or in a region of the air feed apparatus, and a bypass apparatus disposed in the nozzle ring. The bypass apparatus may form a connection between the nozzle ring and the discharge element. Further, the bypass apparatus can discharge particles that are difficult to grind, for example, ductile particles such as iron particles, from the grinding process. In some examples, the bypass apparatus includes a gas-impermeable outer skin in the region of the air feed apparatus.Type: ApplicationFiled: February 25, 2016Publication date: March 22, 2018Applicants: THYSSENKRUPP INDUSTRIAL SOLUTIONS AG, thyssenkrupp AGInventors: Björn Olaf ASSMANN, Carsten SACHSE

Publication number: 20180078943Abstract: A grinding chamber of a grinding device for vegetal products suitable to form beverages includes, in its interior, a pair of grinders axially overlapping each other, one of which is rotatable with respect to the other which is kept stationary, a grinder support at least for the rotatable grinder, a motor member connected to the grinder support for setting the rotatable grinder in rotation. The grinding chamber is formed by a first bottom wall, perpendicular to the axis of rotation of the rotatable grinder, adjacent and below the support thereof, and at least a second cylindrical wall, connected axially to the first wall at the peripheral boundary thereof. The grinding chamber also includes a first opening for introducing the product to be ground and with a second opening for discharging the ground product. A labyrinth is provided between the peripheral boundary of first wall and the grinder support.Type: ApplicationFiled: September 19, 2017Publication date: March 22, 2018Inventor: Giacomo Abbiati

Publication number: 20180078944Abstract: The purpose of the invention to provide a method for determining a lifting angle of a charge inside a grinding mill at a specific point in time and a method for positioning a grinding mill which is more accurate. Method for determining a lifting angle of a charge inside a mill body of a grinding mill being rotatable through a drive train, the method comprises the following steps of rotating the mill body; determining a reference lifting angle and a corresponding reference driving torque of the drive train at a reference point in time; calculating a fill factor for the reference point in time based on the reference lifting angle and the reference driving torque; determining a driving torque of the drive train; and calculating the lifting angle based on the driving torque and the fill factor.Type: ApplicationFiled: November 28, 2017Publication date: March 22, 2018Inventor: Martin Pischtschan

Publication number: 20180078945Abstract: The present invention is a processing device, such as a macerator for use in processing various types of food products, that includes an automatic adjustment mechanism for adjusting the position of a roller disposed within the macerator. The mechanism includes a controller operably connected to a motor that can move the roller within the macerator to vary the position of the roller with respect to another roller located in the macerator. Inputs to the controller are used to control the operation of the motor to move the roll into a desired configuration associated in a storage medium in the controller with a particular food product to be processed. The input to the controller can also be used to simultaneously adjust the position of other components of other processing devices in a food processing system, such as an injector to remove the need for individually adjust each device in the system.Type: ApplicationFiled: November 30, 2017Publication date: March 22, 2018Applicant: John Bean Technologies CorporationInventors: Ralf Ludwig, Richard Timperio

Publication number: 20180078946Abstract: A magnetic separator for a product having ferrous and non-ferrous particles includes a housing having an entry section and a cleaning section. A driven magnetic roller is disposed within the cleaning section. A non-magnetic isolator including inner and outer surfaces is positioned in the cleaning section and surrounds and seals the driven magnetic roller. The driven magnetic roller is positioned proximate the inner surface of the non-magnetic isolator. The magnetic roller includes a magnetic field that penetrates a flow of product contacting the non-magnetic isolator wherein ferrous particles travel along the outer surface of the isolator and non-ferrous particles do not travel on the outer surface separating the ferrous and non-ferrous particles. The driven magnetic roller has no direct contact with the product.Type: ApplicationFiled: September 21, 2017Publication date: March 22, 2018Inventor: Darren Paul Butler
