The present invention concerns the improvements in the hammer mills, secondary and tertiary, reversing and not, that allow to resolve all the big problems tied to the shattering of the inert hammers; the all, through the use of a special device circular of rotation, endowed with blades of interception in equal number to that of the hammers that launches the inert material against the front of the hammers, obtaining the shattering totally to impact, in place of the traditional shattering for crushing between hammers and armours. The surprising resulted obtained are: increase of production from the double one to the triple one, with almost absence of recycle; good polyhedric nature and granulometry, with droop 70% about of dust in the obtained product; reduction of usury in the hammers and armour; possibility to produce thin sands, with non attainable speed with traditional mills; almost absence of dust freed during the operation with consequent elimination of environmental impact and guardianship of the health of the relative employees to the jobs.
Broyeur à marteaux secondaire ou tertiaire comprenant une trémie (10) et un carter (8) contenant un premier rotor supérieur (1) possédant des marteaux (3) disposés dans un sens radial, et un deuxième rotor inférieur (5) présentant des pales radiales (6), de sorte que le matériau à écraser est lancé par le deuxième rotor contre le premier rotor, lorsqu'ils sont en rotation. Le nombre de pales est égal au nombre de marteaux et le rapport entre le diamètre du premier rotor et celui du deuxième rotor est de 1,5-2:1, si le broyeur est un broyeur secondaire, et de 4-7:1, si le broyeur est un broyeur tertiaire.
