Definitions
- the invention relates to methods for medium and fine crushing in eccentric cone crushers and can be most widely used in the construction and mining and metallurgical industries
- the method includes installing an unloading gap between the crushing cones, starting up the crusher, loading the crushing chamber with the initial mineral, crushing it, determining the size of the crushing product and adjusting the size of the gap to obtain the desired size of the product.
- the known method involves the difficulty of setting an accurate and possibly small gap in order to obtain the maximum degree of crushing.
- This method does not make it possible to increase the degree of crushing more than 7 ⁇ 8.
- the aim of the proposed method is to reduce the stages of crushing and grinding by combining at least two of them in one unit by increasing the degree of crushing.
- the objective of the method is the organization of such a sequence of operations and the introduction of new operations that provide a high degree of crushing with increased productivity and reduced specific energy consumption.
- SUBSTITUTE SHEET (RULE 26)
- the problem is solved in that in the proposed method, including setting the size of the discharge gap between the crushing cones, starting up the crusher, loading the crushing chamber with the source material, crushing it, determining the size of the crushing product and adjusting the size of the discharge gap to obtain the required size of the finished product, in accordance with the present invention, first the size of the discharge gap is set equal to zero, then the crushing chamber is loaded with the starting material, then the crusher is started, according to le which increase the size of the discharge slit to achieve the desired performance and the desired size of the final product is obtained by adjusting the frequency of rotation of the drive cam.
- the method can be implemented in a conical eccentric crusher.
- FIG. 1 shows the crusher in longitudinal section in a static state.
- FIG. 2 shows the working part of the crusher in one of the operating conditions.
- opening gap we mean the sum of the radial distances between the bases of the inner and outer cones (position 11 of Figs. 1 and 2).
- the size of the discharge gap (11) is set equal to zero. This makes it possible to load the crushing chamber with raw material that will not wake up through the crusher without treatment. After loading, the crusher is started, as from the prior art it is known that the operation of the crushing unit at idle is undesirable - the friction of the cones against each other leads to their premature wear. Then, the required size of the discharge gap is established (11), taking into account the fact that the larger the size of the discharge gap, the larger the throughput cross section of the crushing chamber, the higher the productivity of the crushing process. Moreover, such an important parameter as the fineness of the finished product is controlled by adjusting the speed of the eccentric: by changing this parameter, you can adjust the magnitude of the crushing force and the frequency of application of force.
- the initial (starting) size of the discharge gap is chosen much larger than what is required technologically. This is done in order to reduce the load on the eccentric drive (8) when filling the crushing chamber with the starting material.
- the crusher starts at idle, then the source material is loaded,
- the crusher contains a housing (1) with an external crushing cone (2), inside of which there is an internal crushing cone (3), the shaft (4) of which is supported through a spherical support (5) (consisting of a heel and a thrust bearing) on the piston (b) of the hydraulic cylinder ( 7) located in the housing (1).
- An eccentric (8) mounted on the shaft (4) is mounted for rotation relative to it, mounted inside the cylindrical bearing sleeve (9) with a radial clearance (10) exceeding the size of the discharge gap (11) between the cones (2) and (3).
- the cylindrical sleeve (9) is coupled to an electric motor (14) through a gear pair (13).
- the upper part of the shaft (4) is placed by means of a hinge (15) in the traverse (16).
- the drive element (12) is rigidly fixed on one side to the cylindrical sleeve (9), and, on the other hand, is inserted into the groove (17) of the eccentric (8).
- Crusher works as follows.
- the degree of crushing of the crusher can be adjusted in the range from 4 to 30. That is, it is possible to obtain 100% of the product smaller than 20 mm or smaller than 5 mm from the same starting piece, for example, 100 mm.
- the method allows you to replace the stage of fine crushing and the first stage of grinding, for example, a core mill, i.e. ensures the full implementation of the task.
