Mechanical granulation process

A mechanical process of cold granulation comprising devices intended to produce spherical concentrated aluminum particles having a range of distribution, said process comprising the following steps;

• a selection of at least one product to be treated,
• having a press (24) and making blocks of said one product,
• having a shredder (32)and making cuttings of said blocks,
• having a granulator (42) comprising primary means of cyclone (50) and concentrating the distributed cuttings,
• having a sifter (46) and removing fine particles and powders,
• having a separator (62) of granules collecting on one side a range of fine granules,
• having secondary means of cyclone (70) collecting remaining dust then leading said dust towards a secondary filter (74) removing said dust letting secondary filtered air (76) out.

A group of devices for cold granulation intended to produce concentrated and spherical aluminum particles from 1 mm to 3 mm, said group of devices comprising:

• a press (24) intended to make blocks,
• a shredder (32) intended to make cuttings of said blocks,
• a granulator (42) intended to concentrate distributed cuttings, said granulator comprising suction means (50) sucking from bottom to top to separate products according to size, the higher the suction the larger the granules entrained by the suction,
• a sifter (46) intended to remove fine particles and powders,
• a separator (62) of granules collecting on a side a range of fine granules,
• secondary means of cyclone (70) collecting remaining dust then leading said dust towards a secondary filter (74) removing said dust letting secondary filtered air (76) out.
