Information about the V42

The Alrena precision macerator is a cutting macerator with unique precision in slurry distribution. The patented air flow system combined with the rotor and different possibilities of cutting plates ensures very precise slurry distribution for both large and small application quantities. The rotor and cutting plates are easy to convert into different configurations, allowing various application rates to be applied with the same machine. Furthermore, the Alrena macerator has a 5” inlet without constrictions which makes the distributor suitable forhigh capacity spreading. Due to the low hydraulic power requirement of only 35L/min and the compact design, the macerator can be easily built onto various agricultural machines. When running dry, almost no temperature rise occurs within this specially developed macerator so wear occurs little or not at all.

Rotating cutting system

The basis of the Alrena precision macerator is a specially developed cutting system with rotating round knives. Due to different pivot points and the resistance of the solid parts to be cut in the slurry, the knives keep rotating constantly. This constant rotation of the cutting discs ensures that each cut is performed witha new piece of knife, thus significantly reducing wear. In addition, the rotating movement has the advantage that the cutting discs are self-sharpening. This extends the service life of the wear parts. A coil spring ensures an even blade force.

Interior construction V42

The inside of the macerator head consists of a rotor and two hole disks with 21 outlets on each side. Alrena has several rotors and hole discs to adjust the capacity of the precision macerator. As standard, a precision macerator is equipped with a 6-knife rotor (R6) on both sides and a standard G5 hole disc. You can ask Alrena for exactly the right configuration when the capacity needs to be very small or large.
