Description

The subject of the invention is a roller mill, designed to crush lumps of non-moist clay after dehumidifying clay clay in the process of forming a brick using the dry-pressing method.

A distinctive feature of the mill described is that the rollers are composed of radially arranged knives made of strip steel mounted on a shaft, with the rows of one drum entering the intervals between the blades of the other roller.

FIG. 1 shows schematically a roller mill, an end view, in FIG. 2 - drum rings, front view, in FIG. 3 is a section along A-A in FIG. 2; in fig. 4 - a knife; in fig. 5 - clamping cheek, front view; in fig. 6 is a section along BB in FIG. five; in fig. 7 - bed, front view; in fig. 8 is a section along BB in FIG. 7

Roller mill consists of two rollers. Each drum is assembled from 64 plates made from boiler iron. The drum rings each have sixteen nests 2, about 3 mm deep (thick as knives) for inserting knives 3 and two holes 4 in each bend for bolts that hold all the plates together in a common drum together with the knives 3 and cheeks. In the center of each plate there is a hole 5 for pulling on the shaft and a groove 6 for the tongue.

Clamping jaws 7 with bolt holes 4 and a hole 5 for pulling the cheek onto the shaft and the tongue groove 6 are provided on the outside of the rollers. The cheeks serve to close the knives on one open side of the last plate and fix the rollers on the tongue. Since the slotted grooves in the cheeks are not through, the cheeks, when bolted together with the plates, do not allow the rollers to move on the key along the axis of the shaft.

The rollers are mounted as follows.

A clamping jaw 7 is put on the shaft with a keyway, then the plates are threaded and 2 knives are inserted into the sockets 2. Simultaneously with the first plate, they are inserted into the hole of each socket

one eb-nTy / ifobb knives did not fall out during assembly. The B-Topyso iBaH BMHYio is then strung on the shaft, then all the other bolts are inserted into the holes, and all the plates with the cheeks are clamped with bolts to avoid knocking the knives in the slots, due to the development of nests or inaccuracies. size knives width.

The two rollers assembled in this way are mounted on cast iron beds 8. The ribs can be sliding or ball. To prevent the quality of the crushed mass from being disturbed when the blades are triggered due to an increase in the clearance at the end, their rollers can be moved, for which the beds are placed on the slide 9. The rollers are placed opposite one another in such a way that the zeros of the first roller are between the blades of the second roller.

Both shafts are worn on a shaft, and the diameter of one shaft is three times larger than the diameter of the other. The pulleys fall on the opposite ends of the shafts.

The rolls are covered with a metal casing 10 in order to avoid scattering clay clay on the sides. In the casing there is a loading 11 and a discharge 12 opening.

The roller mill is installed after a two-drum bollard, in front of which is a humidifier. The power of the electric motor for a roller mill requires about 3.0-3.5 kw.
