Mini Goliath is the smallest of the toothed roller granulators. It is designed for granulating small sprues and reject parts beside the machine.
Its standout feature is its low operating speed: 25 revolutions per minute. At this speed the material is cut, not smashed by impact; the result is very little dust and quiet operation. Because the total connected load is 0.55 kW, the machine can be installed beside the press without any additional electrical infrastructure.
Low construction
With the standard hopper the overall height is 585 mm, and in the lowest possible arrangement it drops to approximately 505 mm. On lines where space is tight beside or under the injection molding machine, this is the deciding dimension.
Three cutting chamber sizes
The cutting chamber depth is the same on all three models (134 mm); the width and the number of pre-cutters vary. A larger number of pre-cutters ensures that a part entering the hopper is fed into the cutting chamber more evenly.
Why slow speed?
High-speed blade mills break the material up by impact; this produces heat, noise and dust. The toothed roller design cuts the material at low speed. The result is quieter operation, markedly less dust and a more uniform granule size. If you are going to return the granulated material to production, these three points are reflected directly in your part quality.
Life of the cutting elements
The combs, counter-combs and pre-cutters are designed to be reversible: when one face wears, it is removed and turned round so that its second face is used. In practice this doubles the life of the cutting elements. If you process abrasive material, a wear resistant coating option is available for the cutting elements.
