Comminuting device and method for comminuting material

#This application is a National Stage Application under 35 U.S.C. 371 of co-pending PCT application PCT/NL2011/050056, designating the United States and filed Jan. 27, 2011, titled “Comminuting Device and Method for Comminuting Material”, which claims the priority benefit of NL Patent Application No. 2004156, filed Jan. 27, 2010, titled “Comminuting Device and Method for Comminuting Material”, the entire disclosure of each of which is hereby incorporated by reference for all purposes.

#The invention relates to a comminuting device for comminuting material. The comminuting device is more particularly used to comminute green waste, waste wood and/or demolition wood.

#Comminuting devices known in practice comprise an infeed conveyor for supplying the material to be comminuted, for instance green waste, and an outfeed conveyor for discharging material comminuted with the device. The comminutor is provided between the two conveyors. Such a comminuting device is in practice often transported with a truck. A crane or power shovel is also transported for the purpose of filling the infeed conveyor with the material for comminuting.

#Further advantages, features and details of the invention are elucidated on the basis of preferred embodiments thereof, wherein reference is made to the accompanying drawings, in which:

#FIG. 1 is a side view of a corruninuting device according to the invention during transport;

#FIG. 2 is a perspective view of the comminuting device of FIG. 1;

#A semi-trailer combination 2 with truck and trailer (FIG. 1) is used to transport a comminuting device 4. The front side of comminuting device 4 is connected here to the truck and the rear side is connected to a supporting frame 6. In this way comminuting device 4 can be transported over a ground surface 8. Comminuting device 4 is provided on one side with an infeed bin 10 and a shredder or comminutor 12. An outfeed conveyor belt 14 is provided on the other side of shredder 12. Outfeed conveyor belt 14 pivots around rotation shaft 16 on which the first part 18 of outfeed conveyor belt 14 is rotatably mounted. Outfeed conveyor belt 14 is further provided with a second rotation shaft 20 between first part 18 and a second part 22 of outfeed conveyor belt 14. Comminuting device 4 further comprises a cab 24 which is connected using an arm 26 to upright 28 via a rotation shaft 30. In the transport mode cab 24 is situated substantially in the interior of infeed bin 10. Further provided on arm 26 is a cylinder 32 with which cab 24 can be lifted to some extent out of infeed bin 10.

#A first set of legs 34 is provided on the side of infeed bin 10. A second set of legs 36 is provided on the side of the outfeed conveyor belt. In the shown embodiment caterpillar tracks 38 for positioning comminuting device 4 are provided between the first and second set of legs 34, 36. Comminuting device 4 also has a gripper arm 40.

#In the shown embodiment a comminuting device 4 has a capacity of about 100 tonnes of green waste per hour depending on the material to be comminuted. The weight of device 4 lies between 15 and 25 tonnes. Infeed bin 10 has a volume of about 5 to 10 m3. In the shown embodiment outfeed conveyor belt 14 has a width of about 90 em and during use carries the comminuted material to a height of about 5 meters. The overall length of device 4 amounts in the shown embodiment to about 10 meters, with a height in the range of 3.5 to 5 meters. Other embodiments have corresponding dimensions.
