Reduction of refining energy during mechanical pulping [PDF]
The effects of pressurised compressive chip pre-treatment and low dosage sulphite pre-treatment were evaluated for production of thermomechanical pulp in mill scale trials using Norway spruce (Picea abies) at the Braviken paper mill (Holmen Paper AB ...

Design of a Pendulum Prototype for Dynamic Testing of Material Removal Using Picks
The need for large and fast excavations, together with noise and vibration limitations, means that mechanical removal is increasingly used rather than blasting.

Technology of Rock Destruction by Combined Explosion-Mechanical Load [PDF]
Background. Rock drilling is characterized by an energy capacity of more than 120 kWh/m3. This is due to the fact that about 90 % of the energy is expended on the “preparation” of rocks for destruction.

Influence of carbon black trimodal mixture on LDPE films properties: Part3 – Fillers [PDF]
Previous studies in this journal reported a two-part investigation on carbon black (CB) dispersions in LDPE films. In PART01, trimodal CB mixtures were evaluated using a Design of Experiments (DOE) to assess colorimetric and rheological properties ...

Research on Interdependence between Specific Rock Cutting Energy and Specific Drilling Energy
A method based on extensive laboratory and field measurements was developed to determine the dependence of specific rock cutting energy (SEc) on specific drilling energy (SEd) for machines with different operating and design characteristics and similar ...

Investigation of selected independent variables on extrusion of rice semolina with and without propeller [PDF]
The influence of screws with and without propeller, as well as the independent variables of material moisture content, working screw speed, feeding screw speed and die temperature on the changes of some physical and mechanical properties during singles ...
