РЕЖУЩИЙ ИНСТРУМЕНТ ДЛЯ ГРАНУЛЯЦИИ ПЛАСТМАСС

Для повышения эксплуатационной надежности и долговечности инструмента он содержит режущий элемент, состоящий по крайней мере из трех слоев: слоя из инструментальной стали, твердосплавного слоя и опорной подложки, пластичность которой выше пластичности первых двух. Положительный эффект: повышение прочности режущего инструмента и обеспечение его работоспособности в условиях экстремальных нагрузок. При этом, благодаря более высокой пластичности и податливости материалов опорной подложки, достигается способность режущей части выдерживать деформации за пределами упругости твердосплавного слоя и слоя из инструментальной стали.

ИНСТРУМЕНТ ДЛЯ ОБРАБОТКИ ПЛАСТИЧЕСКИХ МАСС

Предлагается режущий инструмент, армированный высокоизносостойким элементом, с увеличенным ресурсом работы. Увеличение ресурса работы достигается за счет изменения конструкции инструмента и перераспределения функций составных слоев режущей части и сокращения числа последних. Согласно изобретению, количество слоев режущей части сокращено до двух с размещением износостойкого слоя за демпфирующим стальным слоем, служащим продолжением корпуса инструмента и являющимся опорной (несущей) стенкой двухслойной зоны. Сокращение числа стальных слоев с 2 до 1 позволяет увеличить протяженность армированной поверхности инструмента, контактирующей с фильерой, и повысить ресурс работы на 20 - 25%. Инструмент может быть использован на операциях грануляции, измельчения, истирания пластических масс.

A discharge extruder may be fed via the aperture or the sleeve can be rotated to eject the output of the machine through a second outlet.

Internal mixer for kneading plastic compositions, particularly rubber

An internal mixing apparatus for mixing plastic materials, especially raw rubber, has a mixing chamber defined by substantially parallel cylindrical individual chambers. Each of these chambers holds a rotating shaft and the two shafts rotate in opposite directions. In one embodiment of the invention, the shafts have a cylindrical outer surface on which is disposed at least one principal conveying and mixing vane. The vanes on the two parallel shafts are disposed in mirror symmetry so that the ridges of the vanes roll off against one another with or without contact. The principal vanes terminate ahead of the end faces of the mixing chamber, thereby defining free passages permitting the transverse motion of the material to be mixed. Within these passages, the shafts carry scraping vanes for preventing the accumulation of stationary material. In another embodiment of the invention, the vane cores are conical and the height of the vanes changes continuously so that the wall clearance between ...

CELLULOSIC MICROPOWDER PRODUCTION SYSTEM

An improved process is provided for reducing cellulosic biomass into air suspendable micropowder. Although the process is particularly suitable for processing empty fruit bunches of oil palms, it is adaptable to most cellulosic biomass.

These pieces are then processed by a tandem line of four pairs of grooved rollers each successive roller having a larger number of grooves. This process squeezes moisture from the biomass and reduces the material into millimeter scale pieces. After an optional drying stage, the material is fed into a terrace line of three or four essentially smooth rollers which squash the material and reduce the particle size into a micrometer scale. Finally, the material is suspended in an air stream and fractionated by a cyclone and bag filter system. 1.

Method for producing pellets from film

A device and method for producing pellets from film. A cradle is rotatably mounted about a longitudinal axis of rotation to a main frame. An axle arranged perpendicular to the longitudinal axis holds one or more rolls of film. A plurality of drive rollers pull the film from the rolls while the rolls are rotated on the longitudinal axis twisting the film into a strand.
