Coal-water slurry fuel was made in a ball mill which pulverised the coal or coal sludge. This was done near a coal mine in Belovo, Siberia. The coal-water slurry fuel was transported through a pipeline to Novosibirskaya TEC-5, Novosibirsk, a distance of 262 km (163 mi). The pipeline had three intermediate pumping stations.

Aside from common ball mills there is a second type of ball mill called a planetary ball mill. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun

Global improvements in energy efficiency have been declining since 2015. The Covid-19 crisis adds an extra level of stress. As a result of the crisis and continuing low energy prices, energy intensity improved by only 0.8% in 2020, roughly half the rates, corrected for weather, for 2019 (1.6%) and 2018 (1.5%).

Mechanical alloying is a solid-state powder processing technique that involves repeated cold welding, fracturing, and rewelding of powder particles in a high-energy ball mill. Originally developed about 50 years ago to produce oxide-dispersion-strengthened Ni- and Fe-based superalloys for aerospace and high temperature applications, it is now recognized as an important technique to synthesize

First up, combustion. This is where heat produced by burning waste produces heat, driving a turbine to generate electricity. This indirect approach to generation currently has an efficiency of around 15-27%, albeit with a lot of potential for improvements.

The researchers can obtain a powder of the corundum nanoparticles by simply grinding lumps of boehmite, aluminium oxyhydroxide contained in the frequently occurring ore bauxite, in a ball mill for 3 h and then heating them briefly. Until now, chemists were only able to produce corundum from other aluminium oxides or hydroxides if they fired the starting materials at temperatures greater than

If the energy to produce new surface by single-particle breakage is used as the basis for evaluating efficiency, then the efficiency of ball milling has a more realistic value of about 15% for the comminution of quartz and soda-lime glass. In a second approach, comminution efficiency is based on comparing the energy to produce some size distribution parameter of the product from ball milling
