Alrena horizontal precision macerator H24

The Alrena precision macerator H24 has 24 outlets with a diameter of 50 mm.

The Alrena horizontal precision macerator is a newly developed cutting and distributing system with very high precision in slurry distribution. The macerator has a specific controlled air flow, which optimises the ratio of slurry to air and ensures a very constant spreading. The ALRENA precision macerator has a high air passage and a 6” connection for the slurry to come in. In case of dry running the temperature of the newly developed macerator stays low so there will be no or little wear.

Unique in:

■ A very precise distribution of the slurry

■ Unique controlled and constant air passage

■ Cutting system with rotating knives

■ Dry running is possible, temperature of macerator stays low

■ Other types and configurations possible

Guaranteed air flow

The Alrena horizontal precision macerator is equipped with a controlled and guaranteed air flow system. The air is sucked in at the bottom and through a special hollow shaft the air is guided to the rotor. The air in the rotor will be divided to the chambers in which the round knives are located. After cutting the slurry, the air will immediately follow the slurry through the hollow knives into the hoses, so that the slurry flow is very constant and stable. The spreading of the slurry is therefore constant and very precise. Because of this precise distribution the nutrients will be used optimally.

Interior construction H24

The inside of the macerator head consists of a rotor and one hole disc with 24 outlets. 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) and a standard hole disc. You can ask Alrena for exactly the right configuration when the capacity needs to be very small or large.
