High-torque granulator cuts thermal degradation
Hellweg Maschinenbau has extended its 600 series granulator at the upper end, by adding a model with a 1,500mm working width. The new MDS 1500/600 version
offers high torque due to the high stability of the entire machine housing and the heavy-duty rotor. “Aside from the high performance, the machine has other strengths – such as in flexibility on account of its modular design,” said Mark Hellweg, managing director. “For example, straight or slanted housing versions are available, as well as different rotor and stator designs, in order to address the different tasks required in the market.” The double-slanted scissor type of
cutting ensures that the large granula- tor can shred articles including thick-walled mouldings and sheets. In
CPP
continuous operation, maximum heating of material during grinding is no more than 33°C – and a maximum of 38°C when shredding glass fibre reinforced plastics. This removes the possibility of thermal degradation. Granulators in the 600 series
granulators offer the possibility of full scalability. Despite difficult material tasks, the regrind produced can be easily processed further. The latest granulator can be adapted according to predetermined conditions. The 600mm rotor works at a speed
of around 400rpm, and has a working width of 1,500mm. A choice of rotors is offered, with three to seven continu- ous rotor cutting strips. The usual process of setting rotor blades has been eliminated. For film applications, the number of
stator blades can be increased to four. There are special rotor versions for lumps and film applications, different wear protection packages for glass fibre reinforced material applications, and noise protection cabins. �

BOPP Chill roll with fast changeover Polibak
Amut has developed a new line for the production of cast PP film. The 2,100mm-wide ACP series has been designed to make smooth, general- purpose film, and film with an embossed surface for stationery applications such as document folders. In order to produce both types of CPP film surface, the line has two different chill rolls. A fast-change system enables production to be switched between the two very quickly. The line has a four-layer multi-manifold die which allows very accurate

distribution of the layers by using four extruders. An independent rotary arm type winder is equipped with an in-line cutting system for the production of finished rolls

without any reduction of maximum winding diameter, even when running multiple rolls in winding and with absolutely minimum tail, says Amut. �

BOPP line Polibak, a leading plastic film producer in Turkey, is planning to boost output by 40% by installing a new line from Brückner. The company, which has two facilities in Izmir, will now install a 10.4m wide line that has produc- tion speeds up to 525m/ min, equivalent to an output of over 7,400kg per hour of five-layer film. Brückner says that, when installed, it will be the largest BOPP film production line in Turkey. �
