A grinder of solids or solids in liquids has a multiple milling stage. A rotating disc plate (22) carries cutting elements (28) on one side and hamme r elements (30) on another, both located at the circumference of the disc plat e. The disc plate (22) is rotated in a screened chamber (16) to which the solid s or the liquids containing solids to be ground are introduced. Ground product or slurry containing disintegrated solids is passed through the screen (20) before discharged. The use of disc plate and milling elements reduces requir ed torque, leading to improved energy efficiency and results in better performance of the grinder.
