The article discusses the use of “Open Source” software Quantum GIS (QGIS) to search for the optimal location of observation network points in open-pit mines. The exploitation time of open-pit mines is ranges from a few ...

Nanotechnology and nanomaterials are a rapidly growing interdisciplinary fields of knowledge, spanning many areas of research. Nanomaterials can be classified into nanostructured materials and nanophase/nanoparticle ...

Until now, the general construction of the plasticizing system has assumed placing the screw in a fixed barrel. However, at the end of the 20th century, a completely new concept of the design of an extruder was put forward, ...

As the technology of polymer extrusion becomes more sophisticated, demand on possibility to accurate simulate extrusion process in full 3D rises significant. The single screw extruder (SSE) is one of the most widely used ...

The article introduces an innovative concept of a screw of an extruder used for granulation of polymer materials. Three construction solutions were introduced, differing in the construction parameters of the screw. The ...

This paper aims to numerically evaluate a new concept of construction in a single screw extruder design. Rotational barrel segment introduced in 1998 significantly changes the kinematics of movement in a single screw ...

Newex project The goal of the NEWEX project is the construction and testing of the new innovative extruder. By the application of a new concept of vital parts: innovative active grooved feed section (IAGFS), original ...

Przedmiotem poniższej pracy są szaliki kibiców piłki nożnej w Polsce, a dokładniej ideologia na nich wyszyta i ukazana. Podczas prowadzonych badań terenowych oraz jakościowych bez problemu można było zauważyć, że szalik ...

The article presents a new concept of active grooved feed zone in an extruder for granular polymer plastics. The innovation of this concept lies in the use of a properly shaped sleeve with a set of grooves and a closing ...
