Description

one

This invention relates to a device for grinding materials and can be used in the building materials industry;

In the famous drum mill type Aerofol discharge device is aerodynamic. The material due to the discharge created by the mill fan rises to the separators located above the mill l3

Such a system allows for construction to be less buried in the ground or to make foundations of lesser height to provide material overload for further processing, which saves on capital investments, although it requires large energy inputs for aerodynamic unloading.

A disadvantage of the known mill is the impossibility of transferring material for further processing to the equipment located above the mill during the wet production method, or in the dry production method without aerodynamic unloading, without subsequent equipment located below the mill, which in turn will increase the cost of construction of technological lines.

The closest in technical essence to the present invention is a device for unloading material from a drum mill, containing an annular chamber adjacent to the discharge point, divided by longitudinal radial partitions into compartments with inlet and outlet openings, as well as chute 1.2.

However, this device, with its relative simplicity of design, allows the mill to be unloaded only at the mark located on the axis of the discharge point. This requires the subsequent location of the equipment at levels that allow the installation of additional transshipment means for subsequent technological devices, which leads to an increase in capital expenditures for construction. The purpose of the invention is to simplify the transfer of grinding products to subsequent technological devices and reduce capital costs during construction. This goal is achieved by the fact that, in a device for unloading material from a drum mill, containing an annular chamber adjacent to the discharge point, a separator with longitudinal radial partitions and compartments with inlet and outlet openings, and a point, the annular chamber is fixed on the outer end knuckles and is provided with a fixedly mounted kraaak, which is joined by means of a hermetic seal to the outlet openings of the compartments, while the chute is mounted coaxially with the radial partition of two adjacent compartments in the extreme upper position and communicated with their cavities. In such a mill, the material is unloaded above the axis. FIG. 1 shows a device for unloading material from a drum drum / longitudinal section; see 2 shows section A-A in FIG. 1. The drum 1 of the mill rotates at loading 2 and unloading 3 trunnions. A lifting and unloading device is rigidly attached to the unloading trunnion 3, which consists of a chamber divided into compartments 5 by means of longitudinal radial partitions 6. Each compartment 5 has an inlet 7 and an outlet 8 aperture. The outlets 8 are sealed with a fixed element 9 mounted on the lid 10, having a discharge opening 11 and a discharge chute 12, the outer and inner diameters of the cartridge k. The required heights of the material during unloading and the mill about its axis are determined (the more material is required to be lifted. The larger the diameter of the drum). The number of compartments 5, the sizes of the openings 7, 8 and 11 and the chutes 12 are determined by the productivity of the mill 304 (the greater the productivity, the larger the sizes of the holes 7, 8 and 11 and chutes 12). The device works as follows. The material after grinding from the drum 1 through the discharge pin 3 enters the chamber C and further into the compartments 5 through the openings 7 when the compartments are in the lower position. When they are lifted, the material moves to the holes 8, which are sealed by a stationary element 9. When the hole 8 approaches the hole 11 in the lid 10, the material enters the chute 12 and further into the unit for processing, which can be set flush with the mill without deepening. The application of the proposed invention will provide savings in capital investments in the case of the need to direct the material for further grinding, due to the fact that no additional burial is required to install additional grinding units. Apparatus of the Invention A device for unloading material from a drum mill, containing an annular chamber adjacent to the unloading trunnion, which is divided by longitudinal radial partitions into compartments with inlet and outlet openings, as well as chute, in order to simplify the grinding products into the subsequent technological devices, the annular chamber is fixed on the outer end of the discharge point and is provided with a fixedly mounted lid, which is mated by means of a hermetic seal to the The openings of the compartments, in this case, the chute is mounted coaxially with the radial partition of two adjacent compartments in the extreme upper position and communicated with their cavities ,.
