Agricultural agitators

Livestock farming produces slurry, which is used as a valuable fertilizer on arable or grassland. Since slurry is produced continuously, it must be stored temporarily in containers, silos or pits. As a result of the storage, floating layers form due to sedimentation.
It is essential to stir the slurry before spreading it on the field. Slurry agitators are used to stir the slurry. On the one hand, agitating the slurry prevents the formation of floating layers, which in turn makes the substrate pumpable and flowable. Furthermore, agitating the slurry homogenizes it, i.e. it mixes it thoroughly. This ensures the best possible distribution of nutrients.

SUMA offers a wide range of slurry agitators for elevated tanks, open or closed pits, slatted floors and ring or slalom channels. SUMA slurry agitators are available with different types of drive:

• Agitator with electric motor as a long axis agitator (e.g. REKORDMIX) or submersible mixers (e.g. OPTIMIX 2G stationary)
• PTO-driven slurry agitator for connection to an agricultural machine or a tractor (Z series: GIANTMIX Z3 HY stationary, GIANTMIX Z4, GIANTMIX Z5)

Long axis agitators

Long axis agitators are available both with and without their own motor. Because they have a drive shaft, they often protrude far into the container, which means they are often used in large containers with large diameters. In motorised versions, the motor and gearbox are designed to be located outside the container. 
Tractor-powered agitators are frequently used on farms. The agitator is not driven by its own motor, but via the PTO shaft of the tractor or agricultural machine. The agitator is therefore not in continuous operation, but is only used temporarily to stir the slurry tank. The impeller is of crucial importance for the efficiency of the agitator. The size of the impeller is selected depending on the tractor power. Optimised impeller geometries enable shorter agitation times and lower energy consumption.
