Hammer Mills 650

100 years of experience and innovation have led to the development of a wide range of high-efficiency hammer mills.  The Ottevanger Hammer Mills 650 series are eminently suitable for grinding granulates up to 20 mm diameter. Depending on the screen-size used, the mill is able to reduce the particle size down to approx. 200 micron. The Hammer Mills 650  features a solid all-welded construction and has a number of benefits, which are mentioned below

Feeding System
For optimum efficiency in grinding it is essential for the feed to be even and for the ground product to be discharged as fast as possible from the grinding chamber. The mechanically driven feeder ensures an even feed over the whole width of the mill and the automatic load control controls the feed in proportion tot he load on the main motor. The drum type will provide a full load in 10 seconds from start up. It includes a permanent magnet and stone trap, and an auto magnet cleaning device.Doorsnede hm
