Acoustic emission is a newly developed method that allows for greater control in the grinding process and the creation of bearing elements with more consistent geometrical properties. Acoustic emission is a technique that can be applied to monitor and control grinding – one of the key processes in the manufacture of bearings and shafts.


Environmentally harmful calcination of lime is circumvented by grinding raw lime with sodium silicate. Chemists at Johannes Gutenberg University Mainz (JGU) in Germany have now developed a method that could drastically reduce CO₂ emissions from cement production in the long run. In this process, the raw lime (CaCO₃) is no longer converted ...


Grinding is a common industrial process in construction-related work. The emissions from grinding metal and other materials can potentially impact the air quality in the region of the work, and thus the health of people who perform the grinding or those nearby. In this study, we measured the size and composition of particles emitted from the


The CO 2 emission of the metal chip was 583 kg-CO 2. The total CO 2 emissions of the production cycle (Pe) are listed in Table A6. The dry conditions emitted the largest volume of CO 2 during production. When cutting fluids or cryogenic coolants were applied in the machining process, Pe was reduced regardless of the cutting tool.


The use of emission factors is the simplest method to estimate emissions from surface finishing process sources. An emission factor relates the quantity of a pollutant released to the atmosphere with a specific activity or in this case a specific process. Emission factors summarized for …


Application of external stimulus in the form of grinding of the In-MOF leads to a drastic enhancement by 29%, ϕ f from 23 to 52%. Solid-state absorption and emission spectra show that the absorption in the region of 368–550 nm gets diminished with a concomitant change in the emission maximum with a blue shift upon grinding.

Environmentally destructive calcination of lime is evaded by grinding raw lime with sodium silicate. Chemists at Johannes Gutenberg University Mainz (JGU) in Germany have recently formulated a technique that could significantly decrease CO 2 emissions from cement production. In this approach, the raw lime (CaCO 3) is no longer turned into burnt lime in coal-fired kilns but is just milled …
