The invention relates to devices for pulverizing materials and can be used in the construction, food, chemical and other industries.

The purpose of the invention is to improve performance.

Fig, 1 schematically shows the proposed feeder, section; figure 2 is the same, top view.

The feeder consists of a housing 1, inside of which the radial partitions 2 are installed along the entire height, just the cavity of the housing 1 for sector volumes 3. The partitions 2 are interconnected by a hinge 4 with the possibility of changing the angle to them. Fixing the partitions 2 in the window position is drying; there is a clamp with 5, which serve to hang and secure the partitions 2 on the upper neck of the housing 1. On the lower neck of the housing 1 with screws

6 suspended cylindrical bob

7 with the possibility of axial movement Underneath the outlet of the housing 1 coaxially with it is a stationary horizontal disk 8 fixed to the axis 9, which in turn is firmly seated in the recess 10. Removable scrapers 11 of the ejecting device are installed above the surface of the horizontal disk 8 which are fixed on disk 12 with equal distance from each other along the circumference of disk 8. Number of scrapers 1 1 is determined by the ratio ZTF / tf Hj where 4, is the minimum angle between partitions 2 Disk 12 is fixed H and with a floor 13 mounted on an axis 9 rotatably from a drive (not shown), the Scrapers 11 are fixed with the possibility of adjusting their position along the radial direction of the disk 8. In the lower part of the device under the clips 11 are mesh, the receiving device in the form of an annular gutter

14 with the bottom inclined with respect to the horizontal 15 toward the discharge tray 16. The angle of the day slope; and 15 of the chute 14 corresponds to the angle of the external friction of the material on its surface and is selected from the condition of unhindered expiration of the product. The chute is rigidly fixed on the frame 17.

The device works as follows.

Mixable components of the mixture pomep1; ashts in sectoral volumes of 3 body 1, in advance in. Depending on the required ratio of components of the mixture, select the corresponding values of the central angles of the sector volumes 3 for each component} and then rotate the radial partitions 2 relative to the hinge 4 and fix them to the desired positions using clamps 5. The components of sector volumes 3 emerge and are located on a horizontal disk 8, forming a frusto-conical view, the outer surface of which is inclined to the horizontal at an angle of repose of the product. By rotating the scrapers D from the shaft 13, which in turn turns about an axis 9 fixed in the binder 10, the components to be mixed are removed from the disk 8 and fall into the annular groove 14, where they slip on the inclined bottom 25 15 and slip through tray 16 is unloaded from the device.

and their location a uniform distance from each other around the circumference

30 of the disk 8 is guaranteed the simultaneous expiration of all components in any period of time. This ensures their uniformity with mixing. By moving the scrapers 11 in the direction of the radius of the disk 8, the amount of product removed can be changed. The latter also depends on the angle of repose of the material. The productivity of the device is also regulated by raising Qmania and lowering the cylindrical pipe 7, which is done with screws 6. This adjusts the gap between pipe 7 and disk 8 and, accordingly, the volume of the product coming from housing 1 on Disk B. The effect of the difference in the angle of repose of different components on the accuracy of proportional mixing is completely compensated for when choosing

Р, -, ratios, sector volumes, i.e. the ratio of the central angles of the sector volumes
