Main Article Content
The process of fine grinding of the granular materials from crushed stone, merble or brittle solid oxide materials is carried out with vibratinf equipment with two or more grinding chambers. The granular material is fed o the fine grinding chamber together with the spherical or cylindrical grinding bodies.
The vibration regime the whole assembly is subjected causes the material to be brought to a powder state with a very high degree of fineness in the range of (5÷10) μm.
The shredded material is used to coat the welding electrodes, the insulation of electrical conductor, the anti-corrosion coatings for special equipment as well as in the chemical and /or pharmaceutical industry.
The study include the dynamic computational model and the foundation of the dynamic vibration regimes so that the technological grinding process may be realized.
Thus, the calculation formulas for the forced vibration amplitudes and working pulsations are given to achieve the optimal regime for achieving the fine grinding degree at particle size class level required by the industrial process technologies.
Thea results of the dynamic modelling, of the optimization of the calculation of the vibration parameters and of the correlation with the grinding fineness were applied for several equipment at the following companies: Ductil Buzău - Bucharest, Medicines Factory Iași, Cement Factory Bicaz-Tașca all in Romania.
Journal author rights
In order for Romanian Journal of Acoustics and Vibration to publish and disseminate research articles, we need publishing rights. This is determined by a publishing agreement between the author and Romanian Journal of Acoustics and Vibration. This agreement deals with the transfer or license of the copyright to Romanian Journal of Acoustics and Vibration and authors retain significant rights to use and share their own published articles. Romanian Journal of Acoustics and Vibration supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in Romanian Journal of Acoustics and Vibration proprietary are defined below:
For subscription articles:
Authors transfer copyright to the publisher as part of a journal publishing agreement, but have the right to: Share their article for personal use (manuscript version); retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
For open access articles:
Authors sign an exclusive license agreement, where authors have copyright but license exclusive rights in their article to the publisher. In this case authors have the right to: share their article in the same ways permitted to third parties under the relevant user license; retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
Rights granted to Romanian Journal of Acoustics and Vibration
For both subscription and open access articles, published in proprietary titles, Romanian Journal of Acoustics and Vibration is granted the following rights:
- The exclusive right to publish and distribute an article, and to grant rights to others, including for commercial purposes;
- For open access articles, Romanian Journal of Acoustics and Vibration will apply the relevant third party user licence (Open access licencses) where Romanian Journal of Acoustics and Vibration publishes the article on its online platforms;
- The right to provide the article in all forms and media so the article can be used on the latest technology even after publication;
- The authority to enforce the rights in the article, on behalf of an author, against third parties, for example in the case of plagiarism or copyright infringement.
