Description

The subject of the invention is a crusher for grinding wet clay and the like of adhering materials, in which hammers hinged in several tiers on a vertical rotating shaft of hammers are used to crush the material by hitting and throwing it on the hull armor.

The features of the proposed crusher include the application of a stepped downwardly extending armored body, which eliminates sticking when grinding wet material. FIG. I shows the crusher, side view; in fig. 2 is a vertical section of the crusher and in FIG. 3 crusher, top view.

The crusher body consists of three main parts: upper-krppki 1, middle-bed 2 and lower-bed 3.

From the inside, the upper-cap 1 is attached at the bottom by bolts 5 of a round armored plate 4. In the cap 1 and in an armored plate, 4 there is a notch 6 for loading. On the cover 1 bolts are fastened to the pillars 7, to which the bolts of the 9 bush 8 of the shaft clamp are fastened. For proper seating of the lid 1 on the mid-bed 2 and for dust removal, there is a tide of 10 in the frame and a 1-notch in the flap.

The mid-bed 2 is made with a downward extension and there are steps inside, to which armor plates I are fastened with bolts 12, located one above the other and consisting of several parts around the circumference, overlapping one another. In the middle bed 2, there is an opening hatch 13 for servicing and changing hammers.

The lower-bed 3 has a bottom rack for the support axle from the center of the axle for passage of the shaft and hatches 14 for the exit of materials from each side. For strength, the bottom of the lower frame has stops 15. The vertical shaft 16, passing through the frame, has an emphasis 17, on which lie distribution rings or collars 18 arranged in several ranks, providing the required distances between the disks 19.

The diameters of the discs 19 increase downwards so that the length of all the hammers is the same. The distances between the hammers around the circumference of the discs are the same and, accordingly, the number of holes for the hammers in the discs also increases with increasing px diameter.

The shaft support 16 at the top is a bush 8 with a ball bearing and at the bottom of the bush 20 with a ball bearing 21 and an axial support 22. To prevent dust and fines from falling on the shaft, sleeves 23 rotating with it are worn. Between the paired discs 19 are located square hammers 24 become.

The crusher is driven in rotation by an electric motor either through a belt drive when installing the electric motor away from the crusher, or in conjunction with the crusher shaft by an elastic coupling when installing, above the electric crusher with a vertical shaft. The crushing of the material is carried out with blows of hammers, as well as blows of armor thrown by blows of hammers, material

Crusher for grinding wet clay, etc., of sticky materials, in which hammers hingedly mounted in several tiers on a vertical rotating shaft of hammers are used to crush the material by hitting and tilting it on the case armor, characterized in that, to prevent sticking of the material during crushing , the crusher body is made stepwise with expansion downwards, r each hammers are located opposite each Kopnvca stage.
