Description

The utility model relates to the mechanical processing of materials and can be applied at enterprises for the processing of ore and non-metallic minerals.

Known devices for grinding materials containing opposing, rotating relative to each other discs, on the working surfaces of which are grinding elements in the form of fingers [1, 2].

A device is known in which, in order to increase the reliability and efficiency of grinding, the striking elements are equipped with rotation bodies [3]. This solution complicates the design and reduces the reliability of the installation.

Devices are known in which, in order to increase the efficiency of the grinding process and productivity, the beater or the method of their placement are improved, for example, in [4] due to the location of the beat in a square, or in [5] due to the execution of the beat with a bevel directed from the center.

A common drawback of all of these structures is the desire to improve the quality of crushing only by changing the parameters of mechanical stress. This approach is limited and does not make it possible to use all the advantages of activating materials in disintegrants. A radical increase in the quality of grinding can be achieved by attracting additional methods of exposure.

The closest (analogue) to the proposed one is the design of the disintegrator, providing for the combination of mechanical activation with acoustic [6]. The design drawback is the impossibility of quality control, that is, the size of the outgoing particles, and the insufficient intensity of the acoustic impact.

The purpose of the utility model is to improve the quality of material processing due to additional thermal exposure and control of the output product, as well as to provide the possibility of processing the activated material with liquid chemicals.

To achieve this goal, a disintegrator design is proposed (Fig. 1), including a housing (pos. 1), inside of which fingers (pos. 2) are placed on the shafts against each other, mounted on disks (pos. 3) in concentric rows, each of which is located between the adjacent fingers of another disk, external disks (pos. 4), one of which is rigidly mounted on the motor shaft, the second through a control mechanism (pos. 5), which regulates the gap between the external disks (pos. 4), a nozzle system (pos. .6) in the inlet pipe (pos. 7), a container with liquid (pos. 8 ) equipped with a heating element (pos. 9), an outlet (pos. 10).

Figure 2 presents a section along the line aa.

The device operates as follows. Using the control mechanism (pos. 5), the gap between the external disks is set so that its size does not exceed the required maximum particle size of the finished product. The liquid is poured into the container and its temperature is brought to 90-95 ° C using a heating element. Raw materials are fed through the inlet pipe, where it is mixed with the liquid sprayed through the nozzle system into the main chamber of the disintegrator. Here, under the action of centrifugal forces, a mixture of a mineral with a liquid successively passes through the rows of fingers and is thrown into external disks in ground form. Particles smaller than the specified gap extend outward and enter the outer circumference of the housing, from where they are removed through the outlet. Particles larger than the gap between the external disks are delayed, regrind due to their own rotation of the external disks, collisions with newly incoming particles, or due to the return to the main working area of the disintegrator, and then removed.

The proposed design of the disintegrator allows not only the mechanical activation of minerals, but also the simultaneous chemical treatment with liquid reagents. Studies have shown that the leaching of metals in the working chamber of the disintegrator simultaneously with mechanical activation can reduce the duration of the process by 2 orders of magnitude, and increase the share of metal extraction from tailings and substandard ores to 85 percent of their initial content.
