A powder supplier, which supplies a powder material to a pressure molding mechanism that continuously generates a molded body, including: a casing having an inlet to which the powder material is supplied and an outlet from which the powder material is discharged; one or a plurality of screws being disposed inside the casing and rotationally driven to transport the powder material in an axial direction; motors being disposed outside the casing and rotationally driving screws; and a regulator being disposed between the screws, and the outlet inside the casing, and regulating a flow of the powder material. The regulator has a rotation shaft perpendicular to the axial direction of the screws, and a width direction of the powder material discharged from the outlet, and being configured to rotate about the rotation shaft.

A material handling apparatus is described comprising a material press body having an inlet and an outlet; a power source for generating an airstream into the inlet of the material press body and through the outlet of the material press body, wherein the airstream captures and feeds a supply material into the material press body; a plurality of press augers for capturing and manipulating the supply material into the material handling apparatus; and a drive system connected to drive and control the plurality of augers.

A plug screw feeder (1) comprises a plug screw (10) with a thread (12) and a plug screw housing (20) surrounding the plug screw. The plug screw housing comprises an inlet opening (24) in a side of the plug screw and in a vicinity of a first axial end (18) of the plug screw. The plug screw is arranged for feeding lignocellulosic biomass material (99) from the inlet opening to a second axial end (19) of the plug screw when being rotated. The thread, in at least a part of an inlet section (15) of the plug screw, presents a jagged peripheral rim (14A) with an inwards directed leading edge. The inlet section is defined as the section of the plug screw passing the inlet opening during rotation. A feeding arrangement and system for treatment of lignocellulosic biomass material comprising such a plug screw feeder is also disclosed.

A system (100) and method to control rheology of ceramic pre-cursor batch during extrusion is described herein. An extrusion system (100) comprises an extruder (122) with an input port (144) configured to feed ceramic pre-cursor batch into a first section (120) of an extruder barrel and a discharge port configured to extrude a ceramic pre-cursor extrudate (172) out of the extruder barrel downstream of the input port (144). A liquid injector (210) is configured to inject liquid into the ceramic pre-cursor batch. A sensor (106) is configured to detect a rheology characteristic of the ceramic pre-cursor batch. A controller (108) is configured (i) to receive the rheology characteristic from the sensor (106), (ii) compare the rheology characteristic to a predetermined rheology value of the ceramic pre-cursor batch, and (iii) generate a command based on the comparison. A liquid regulator (110) is configured to receive the command and adjust liquid flow to the liquid injector (210) based on the command.

A barrel block for a twin-screw extruder constitutes a barrel including a cylinder and has joints at both ends. A first joint includes a first inner joint face on a peripheral edge of a first hole of an insertion hole for screws, and includes a first flank face and a first outer joint face on an outer periphery of the first inner joint face. The first outer joint face is located in the outer periphery of a plurality of first bolt holes. The first outer joint face is more recessed toward a second block end face than the first inner joint face.

A material handling apparatus is described comprising a material press body having an inlet and an outlet; a power source for generating an airstream into the inlet of the material press body and through the outlet of the material press body, wherein the airstream captures and feeds a supply material into the material press body; a plurality of press augers for capturing and manipulating the supply material into the material handling apparatus; and a drive system connected to drive and control the plurality of augers.

The invention relates to a system (1) comprising a feeding device (2) comprising a channel (6) having an inlet (8) and an outlet (10) and a feed screw (12) for conveying biomass material through the channel. The feed screw comprises a screw flight (12b) that extends from a first end (12c) to a second end (12d) and is adapted to form a gas impermeable plug of biomass. The system comprises at least one primary measuring unit (14; 16) adapted to continuously measure a primary variable indicative of the gas permeability of the plug, which primary measuring unit is connected to said feeding device between the first end of the screw flight and the outlet; and a control unit (3) adapted to use said primary variable values to monitor the gas permeability of the plug. The invention also relates to a method for preventing blow back in the above described system.
