A method and apparatus for comminuting particulate material by inter-particle comminution in a bed of particles are disclosed. The apparatus comprises a vertical roller mill with a horizontal grinding table rotating about a vertical mill axis. At least one grinding roller presses resiliently against a bed of particulate material on the grinding track and applies a compressive force. The geometry of the mill is such that the roller engages the bed of particulate material with a substantially pure rolling action. This minimises shear forces applied to the particle bed and minimises the reduction of fines.

L'invention concerne un procédé et un appareil de fragmentation de matière particulaire par fragmentation inter-particulaire dans un lit de particules. Ledit appareil comporte un broyeur à cylindres vertical doté d'une table de broyage horizontale tournant autour d'un axe de broyeur vertical. Au moins un cylindre de broyage comprime de manière élastique un lit de matière particulaire sur le chemin de broyage et applique une force compressive. La géométrie du broyeur est étudiée pour que le cylindre vienne en contact avec le lit de matière particulaire avec un effet de broyage sensiblement pur. Ainsi, les forces de cisaillement sur le lit de particules sont réduites au minimum ainsi que la réduction des fines.
