The SML 60/100 SB 2 from Herbold Meckesheim is a granulator suitable for wet operation with horizontal forced feeding by means of screw conveyors, which allows space-saving installations and easy feeding of the material. Another advantage is the high throughput capacity thanks to a one-meter wide inlet from the hopper and 50-centimeter strong feeding screws that transport the material to be ground to the rotor. Seven rotor knives and now also an optional third stator knife allow up to 21 cuts per revolve. The SB mill can process up to two tons of polyolefins per hour or well over one ton of film. SB mills are also often used for grinding PET bottles and in washing plants for plastics recycling.
In addition to the high throughput capacity, the granulators of the series are characterized by uniform load absorption and low energy consumption. During further development, the focus was again on safety aspects and ease of maintenance: The feeding device together with the hopper can be hydraulically swung away in one piece to open the housing. The case cover with the stator knives in turn opens in the opposite direction, and the knives with the pressure bar are equipped with a lifting device for safe handling.
The discharge trough is also easily accessible. The rubber rings of the machine’s ground plate feet effectively absorb vibrations, which is reflected in low noise emissions. In any case, a sensor monitors the vibrations of the machine. And as familiar from the granulators from Herbold Meckesheim: All wear parts of the rotor of the SML 60/100 SB 2 are easily replaceable.
