The present disclosure relates to a milling device and a method of milling. The milling device can be operated with impact milling an autogenous milling in which particles in the device collide and break the particles up further.

A rotary mill for grinding recycled glass materials into particles has a housing defining an impact chamber with a rotor in the chamber at the bottom of an inclined guide wall underneath the feed opening. The rotor has a plurality of axially extending, angularly spaced massive impact hammers so that the impact hammers impact and deflect the solid materials onto a plurality of shatter bars located at the peripheral wall. Each of the impact hammers has a leading blade element of a hardened steel which has a front face inclined relative to a bottom portion of the guide surface so that an outer edge of the front face is angularly advanced relative to an inner edge thereof.

Reflective luminescent markings on a road or sign surface are formed by applying onto the surface a base material which is liquid in an initial state for application and sets or cures to form a solid layer after application where the base material contains a fine/medium filler material of glass ground from recycled materials in a rotary mill. Coarse material from the grinder is separated out and supplied as a separate material to be applied onto the surface of the layer of base material and fine ground glass. The base material is connected or impregnated with a luminescent material such as photo luminescent 2 4 6 trichlorophenyl in a binder such as polyurea.
