The classic for medium throughputs
ROBUST MACHINE FOR USE IN ULTRA-FINE GRINDING
The high-speed hammer mill VDK is suitable for use in compound feed production, the ethanol industry, the woodworking industry and for grinding a wide range of other products. Its solid construction also makes it suitable for high mechanical loads. The maximum speed of 3600 rpm and longer beaters offer advantages in the fine grinding of pet food and fish feed with high fat contents.
