HPGR High Pressure Grinding Rolls

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

Roughness measurements of stainless steel surfaces

Roughness measurements of stainless steel surfaces. Introduction. Ra value. Surface roughness is a measure of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If these deviations are great, the surface is rough, if they are small, the surface is smooth.

Laser

This paper presents a new method of surface texturing for the cold mill roller called laser-guided discharge texturing to acquire the high surface roughness. In this method, the pulsed laser was focused on the roller surface to produce the metal plasma, and was then used to guide the arc discharge in the gap of electrodes to texture the roller.

Ball lightning

Pyotr Kapitsa proposed that ball lightning is a glow discharge driven by microwave radiation that is guided to the ball along lines of ionized air from lightning clouds where it is produced. The ball serves as a resonant microwave cavity, automatically adjusting its radius to the wavelength of the microwave radiation so that resonance is maintained.
