Abstract:
Rotary forming devices and methods of using the rotary forming devices for producing products such as filled and unfilled “pillow” shaped products. In an embodiment, the invention provides a device comprising a housing comprising a die plate defining a plurality of outlets. The housing defines an inlet. A race plate is attached to the die plate. The race plate circumscribes the outlets of the die plate. A forming wheel is rotatably attached to the die plate. A motor assembly is attached to the forming wheel. The motor assembly is constructed and arranged to rotate the forming wheel in a hypocycloid motion.
Abstract:
An apparatus and method for the granulation of radioactive waste in which a preprocessing method for the vitrification of radioactive waste is simplified to conform to onsite conditions of a nuclear power plant, additives are improved, and pellets suitable for vitrification are manufactured. The apparatus for the granulation of radioactive waste includes: a body frame having an inlet and an outlet; a hopper supplying the radioactive waste to be transferred and fed through the inlet; a feeder transferring/supplying the radioactive waste supplied to a specific position and in a certain quantity; a stirrer pulverizing/mixing lumps of the radioactive waste supplied; an additive supply part supplying a lubricant to the radioactive waste fed into the stirrer; and a pellet press pressing the radioactive waste fed through the feeder into a pellet shape and discharging the pellet through the outlet.
Abstract:
The invention relates to a pellet press (1), comprising a motor (3) having a motor housing (31) and a rotor (32) ar ranged rotatably therein, wherein the rotor (32) is designed as a hollow shaft, a pressing mechanism (2) having a pressing mold (21) and pressing rolls (22) arranged in said pressing mold (21), said rolls being fastened to a stationary shaft (4), wherein the stationary shaft (4) is arranged in the rotor (32) designed as a hollow shaft, and further comprising a mold holder (25) operatively connected to the pressing mold (21), wherein the mold holder (25) and the rotor (32) are connected to each other by means of a connecting means such that a transmission of a torque of the rotor (32) to the mold holder (25) is ensured, wherein the connecting means is a shaft-hub connection.
Abstract:
A computer-based ordering system for ordering goods and services includes a plurality of self-service client terminals and a server. Each self-service client terminal runs a self-order application including a set of interactive menu screens having buttons that allow the customer to select and customize products for the order. An administration tool application communicates with the server to administer the self-service client terminals. The administration tool application including a menu editor that enables the administrator to create and edit the interactive menu screens provided by the self-order application at the self-service client terminals. The menu editor accesses a library of menu templates containing predefined groupings of buttons, and uses the menu templates, as directed by the administrator, during creation and editing of the interactive menu screens.
Abstract:
A solid fuel is formed in a cuber to form body pieces formed of materials extruded through a die with a density greater than 35 lbs/cu ft; an energy content greater than 6500 BTU/lb; transverse dimensions less than 1.5 inches; and a length less than 4 inches; from plant biomass material which contains components when extended of greater than 1.0 inch. Primarily the materials are paper or other cellulose product and crop residue such as wheat straw. The cellulose and lignin from these materials act without additional binders as binders and encasing materials. The moisture content is maintained at a target value by mixing selected quantities of the materials without drying. The cubing machine has a feeding system where the space between the inner rotor and outer casing is smaller than 4 inches and the height of the outer flight is less than 1 inch.
Abstract:
The present invention relates to a method and a device for pelletizing unprocessed cellulosic fibrous material on an industrial scale, and in particular to the use of said unprocessed cellulosic fibrous material pellets as a combustible fuel product.
Abstract:
The present invention is an extrusion molding cavity and a molding machine for loose fabricable biomaterial. The molding cavity comprises molding section and an expanding section in sequence from the inlet side to outlet side of it. A guiding contracted section is located at the inlet side of the cavity and at side of the molding section. The inlet area of the guiding contracted section is larger than the molding section's. The molding unit comprises at least a shaping mold comprising the extrusion mold cavity, an extrusion head driven by power, and an extrusion surface between said extrusion head and shaping mold, wherein the large end of the wedge-shaped extrusion cavity provides a material inlet, and whereby a grainy material is intruded into the shallow end of said guided contracting segment from the large end of the wedge-shaped extrusion mold cavity, compressed, and enters the molding segment.
