Selection and breakage functions of particles under impact ...

In particle comminution processes, the size of the original particles (mother particles) will continuously decrease to finer sizes (daughter particles). This size reduction process can be mathematically represented (in simplified form) by two major functions: selection function (breakage probability) and breakage function.

Breakage Function for HPGR: Mineral and Mechanical ...

The modelling of high pressure grinding rolls is described by the population balance model, a mass balance which includes several functions that are related to the mineral characteristics, material kinetics and operative conditions of the device. The breakage distribution function is one of these functions and refers to the way in which the daughter particles are generated by the process of ...

Detection of tool breakage is of vital importance in automated manufacturing. Various methods have been attempted, and it is considered that the use of discrete wavelet transform (DWT), which is much more efficient and just as accurate wavelet analysis, may provide a realistic solution to the detection of tool breakage in operation.

Spontaneous glass breakage (or not) - Construction Specifier

Mar 21, 2019 · However, glass breakage due to the presence of NiS has been observed in buildings after more than 20 years of service. Where safety or structural requirements mandate the use of FT glass, designers should be judicious with its use, and be aware of and educate their clients regarding the possibility of spontaneous breakage.
