摘要： The method for producing carbon nanotube pellets according to the present invention can reduce the particle size of the carbon nanotubes contained in the pellet by a repetitive extrusion process to produce pellets having improved dispersion characteristics in a solvent. The present invention can improve the problems of the change of the content generated by scattering of powders and safety issues by using carbon nanotubes in the form of pellet. And since the density of the pellet form is higher than that of the powder form, transport, transfer and improvement become easier. Therefore, it can be more effectively applied to the manufacturing of composite materials.

摘要： An infectious waste treatment system and method for decontaminating infectious waste employ a thermal friction extruder in which first and second interleaved counter-rotatable augers include reverse pitch flight sections that urge waste material in a direction opposite to that of the flow stream and into engagement with the back sides of friction plates. This increases the amount of heat generated by the extruder. The reverse pitch flight sections can be selectively replaced with forward pitch flight sections to control the amount of heat imparted to the waste material by the friction plates.

摘要： Pre-shredded, solid plastic and/or rubber waste is fed in to a melting unit (4), of two sequentially linked melting equipments (41,42), where the first melting equipment (41) is constructed with an extruder axis (39) with a thread interruption (44), which shall cause solidity of the melted feedstock and formation of a compaction and a plug, thereby forcing the gases and steams to escape from the feedstock and to prevent back-flow of gases, via an interconnecting pipeline (28) a second melting equipment (42) is mounted, from where the heated high pressure melted feedstock flows into the thermocatalityc reactor (7), where thermal decomposition of the hydrocarbon polymers in the feedstock takes place, then is followed by the collection and storage of the liquid product oil and gaseous end products.

摘要： 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.

摘要： An extruder assembly has a gear box drivable by a motor, an output shaft having a main portion extending through the gear box and rotatable by operation of the motor and gear box, and an extruder housing located forwardly of the gear box. The output shaft has a further portion extending forwardly from the main portion and passing into the extruder housing and having a screw configuration therein for feeding plastic material through the housing when the output shaft is rotated. The main portion of the output shaft is axially slidable in the gear box, and the forwardly extending portion has a diameter not greater than the diameter of the main portion whereby the output shaft can be withdrawn from the housing and the gear box by rearward movement therethrough. A retainer is operable to retain the output shaft in an operative position for rotation to feed plastic material through the housing and also to permit the output shaft to be withdrawn by rearward movement when desired.
