Introduction of mineral fertilizers is performed by centrifugal devices. By quantity of disks, centrifugal devices distinguish one disk and two-disk. On the volume of capacities for storage of mineral fertilizers distinguish bunker and body. Bunker contains volume from 0.5 to 1.5m3. Body has capacity more 2m3. Advantages of bunker centrifugal devices are noted. Material from the bunker moves on a centrifugal disk perpendicular to the rotation plane. At the time of material capture by shovels, crushing of particles and their reflection from shovels and the plane of a disk takes place. It leads to increase in unevenness of introduction of mineral fertilizers. At EMTP chair of the Kuban GAU the centrifugal device with supply of material along shovels is developed. The scheme of the centrifugal device is submitted. A device for introduction of mineral fertilizers contains the one-disk centrifugal device, the cone-shaped bunker and the cylindrical batcher. The batcher gate regulates supply of material on a disk. The technique of determination of design and technological data of the developed design is presented. The place of supply of material on a disk is regulated by rotation of the batcher round a vertical axis. The norm of supply of material on a disk changes the batcher gate. Preliminary control of a place of giving is made on model material with coefficient of friction of f 1. Under production conditions, turn of the batcher from initial situation is made depending on coefficient of friction of the f2 fertilizers. At f1 ˃ f2 turn of the batcher against the direction of rotation of a disk, and at f1 ≤ f2 turn of the batcher in the direction of rotation of a disk
