The bowl granulator consists of the rotational bowl located on the axis inclined at the proper angle (with the possibility of its changing) to the level. Scrapers eliminating dust built-ups on bowl walls and a lance with a device for dosing humidifying substance are inside the bowl. Innovatory elements of this device are: the automatic dosage of the determined amount of humidifying substances in dependence of the charge mass determined by weight and also the solution of the bowl drive allowing for the bowl rotational speed stepless changes. The bowl granulator with the control desk and the devise for dosing the wetting substance is presented in Figure 1.
