It is a simple centrifugal grinder, where the liquid falls by force of gravity from a reservoir placed on the back of the user, from 5 to 10 litres, to a disc rotating at a certain speed, driven by a small electric motor, powered by two standard batteries. The liquid spreads through the disk, with the centrifugal force, which causes ejection tangentially and forms a population of droplets, which fall into a parable and are distributed in a circular 120 cm crown in diameter.
Conditions essential to good use are: The filter in a perfect state to prevent clogging, good quality batteries that power the engine and the exclusive application of herbicides own technique.
