Abstract:

Nanofibrillated celluloses (NFCs) are of high economic value owing to their inherent properties, and the deployed manufacturing technology is critical to producing high-quality NFCs. The grinding efficiency determines the quality of mechanically fibrillated NFCs. Previously, a finished Taylor-flow grinder was developed by addressing the operating issues and drawbacks of a prototype grinder and, subsequently, a pilot grinder. This study evaluated the grinding efficiency of the Taylor-flow grinder using hardwood bleached kraft pulp (Hw-BKP) as a raw material, carboxymethylated with monochloroace

Abstract:

This paper presents a new type of drill grinder based on a special universal joint. The special universal joint is composed of a parallel mechanism with three legs as the inputs. One can rotate as a spindle; other two legs can drive a moving platform and make a drill point get an accurate position in workspace. Due to the simple mechanical structure comparing the grinder with the existing conventional CNC cutting tool grinders, it should be easy for the grinder to manufacture at a low cost. In addition, inverse kinematic equations of the special type of universal joint are derived.

Abstract:

Crusher grinder mempunyai peranan yang sangat penting dalam proses pengelolaan material limbah bottom ash hasil pembakaran batubara di boiler, yakni sebagai penghancur material limbah dengan media crusher. Untuk meningkatkan kehandalan pembangkit, pada crusher grinder terdapat sistem proteksi berupa fluid coupling, yang mengamankan motor ketika crusher tidak mampu berputar karena terganjal oleh material yang sangat keras. Kegagalan operasi pada crusher grinder menyebabkan menyumbatan pada saluran pembuangan limbah (chute) sehingga material yang keluar dari chute dapat menyebabkan pencemaran li

The paper presents the research results related to the operational parameters of a needle grinder for biological materials. The study focused particularly on monitoring the wear of the grinder’s working elements, the pins. During the operation of the device, the level and nature of vibrations in the grinding system were examined. In the next stage, after the grinding of 600 tons of biological material, an analysis of the wear of the metal pins was conducted. The degradation process of the pins was observed based on elements made of both untreated steel and heat-treated steel. The apparatus use

A scientific and technical literature review on machines designed to grind fodder grain revealed that the existing designs of grinding machines—those based on destruction by impact, cutting, or chipping—have various drawbacks. Some disadvantages include high metal and energy intensity, an uneven particle size distribution of the ground (crushed) product, a high percentage of dust fraction, the rapid wear of work tools (units), and heating of the product. To eliminate most of the identified shortcomings, the design of a rotary–centrifugal grain grinder is proposed in this paper. The optimizatio

Angle grinders can cause severe injuries to the head, neck, and face because their high-speed discs do not respect the body's natural boundaries or structures. These injuries can be disfiguring, permanently disabling, or even fatal. To attain aesthetically pleasing outcomes, it is imperative to thoroughly cleanse the wound, excise any damaged tiss
