Slurry distribution
SCALPER© macerator

A good macerator is essential to make sure the injector works properly because some kinds of slurry (especially cattle slurry) are full of fibres and foreign bodies. Now, a blocked opening means the spreading pattern will be uneven and the user will have to stop working.
The solution is the patented JOSKIN SCALPER© system: an extremely efficient macerator made up of 8 self-sharpening circular blades turning freely and driven by a hydraulic motor.
The circular blades and the elliptical arched and off-centre openings of the blade holder inevitably cut all foreign bodies in the slurry.

When the blades strike against too hard obstacles, the rotation direction of the SCALPER© is reversed by the "Switch-Matic" system (option) until the obstacle is chopped. Moreover, an electric reverser with manual control in the cabin is installed on all rear implements fitted with an automaton.

A multi-position manual valve, fixed at the macerator inlet, allows a step by step adjustment of the slurry injection. The precise adjustment is carried out by means of the pressure relief valve and the chosen model of counterblade. 3 types are proposed: flow from 7 to 20 m³/ha, from 12 to 30 m³/ha or from 25 to 50 m³/ha. A double feeding of the macerator is also possible for a higher flow.

The hydraulic circuit is isolated thanks to a cap. A drain makes it possible to check whether the water seal is faulty. The JOSKIN SCALPER© macerators are also sold separately in order to equip existing injectors.

Macerator feeding

The macerator is standard fed through a 6" rubber hose and a 6" adjusting valve.

Vertical macerator

Given their larger width, line spreading booms require a vertical macerator with two cutting systems, one on each side. The slurry under pressure enters the central chamber through a 6’’ inlet, before being evenly distributed between the different openings (24 or 36 depending on the model). In order to have a regular flow, there is an inner air intake in the vertical macerator.

Its advantages are small overall dimensions, limited load losses in the injection pipes (less bends in the pipes) and a more homogeneous distribution of the slurry in the line spreading booms.
