Krah cutting mill CM600
Sustainability hasn’t just become a trend in the past few years – it is also urgently needed. The demand for sustainable products is continuously growing faster. The improvement of energy and resource efficiency in companies all over the world will play an even greater role in the future.
Krah cutting mill for more sustainability
As a large mechanical engineering company, we are of course also thinking about how we can become even more sustainable. Therefore, we have now developed our Krah cutting mill. It enables a direct reuse of processed material. Even if there is hardly any waste during the production of our plastic pipes, it can happen now and again that pipes are not used or have been processed incorrectly and are therefore not used.
In addition, during pipe production, so-called lumps are formed when the raw material is heated in the extruder, which can then not be used. These lumps can be shredded up to a size of 500x200x400 mm in the cutting mill. Pipe segments can be processed up to a size of 500x1500x150 mm. For this purpose, the material is thrown into the feeder and then homogeneously crushed by a single-stage mill. The grinding mechanism is made of a metal part and therefore guarantees enormous stability and a long service life. Depending on the material, the grinding capacity of the mill is between 250 and 500 kg/hr. With a motor power of 75 kW, the mill crushes the raw material into homogeneous free-flowing and sharp-edged material with an average size of about 8 mm. It can then be used directly for pipe production via the machine’s dosing system without the material first having to be processed in a granulator. The shredded material is filled into big bags or suitable containers by an automatic suction system with a hose. A filter system ensures that fine dust is absorbed directly and does not get into the environment.
Comfortable and easy operation
To make working with the cutting mill even more comfortable, a sound insulation can be bought accordingly to reduce noise. But prefarably, the machine is operated in a separated room/hall. Furthermore, the filling level of the material can be checked through a window. The robust cutters can be used double-sided and guarantee a long lifetime and low maintenance costs of the machine. Additionally, the mill only needs a working space of 3x3 m.
