These dusters running are ideal for economic, effective and easy applications of powder to control pests and diseases in field crops, plantations, and godowns, etc. These Rotary dusters are useful for continuous treatment of medium and small holdings of cereals, pulses, groundnut, cotton, tobacco, potato, and vegetable crops. Our Hand Rotary Duster consists of a hopper, fan, flexible discharge pipe, reduction gearbox, rotating handle, shoulder straps, and metering mechanism. The duster has mechanical agitator connected to the gearbox placed in the hopper, which chums the chemical and prevents clogging of the outlet. The adjustable plate mounted below the hopper outlet controls the application rate. This is mounted on the belly with the help of adjustable straps. The discharge pipe fitted with spoon type deflector is directed towards the target continuously rotating the handle. The chemical in dust/powder form drops from the hopper in the discharge pipe having an air stream created by the blower. These dust particles emerging in, the form of cloud from the discharge pipe are carried to the plant where these settle on the leaves, stems and other parts.
