Abstract

A HAMMER HARDWARE, comprising a housing in which a rotor with hingedly suspended hammers is located, has a mechanism for adjusting the working clearance, containing .j / f flf that, in order to simplify the design of the mechanism for adjusting the working gap, the crusher is equipped with additional rows of hammers with fixing means, and the adjusting disk has apertures located around its circumference, each means ksatsii formed as a plate, the ends of which are mounted on the finger and the rod, respectively a position to align with one of the drive apertures and the longitudinal groove.

Description

The invention relates to a device for grinding materials and can be used in construction, mining and other industrial sectors. The purpose of the invention is to simplify the design of the mechanism for adjusting the working gap. FIG. 1 shows a hammermill, a slit j in FIG. 2 - node A in figo 1 (in magnification); Fig, 3 shows the device from above; in fig. 4 - adjustment disk, top view; in fig. 5 - fixture plate. The hammer mill contains a cylindrical case 1 with chute 2, in which a rotor 3 is vertically mounted. The rotor is equipped with mechanisms for adjusting the working gap, each of which is designed as a flange 4, an adjusting disk 5 with grooves 6 circumferentially orifices 7 and mi 8 rotation of hammers. The means of fixing the rotation of the disk is made in the form of a plate 9 with a finger 10 and a rod 1 The hammers 12 are pivotally suspended on the fingers 10, which enter the holes of the flange 4 and the disk 5, and are fitted with 22 nuts 13 on the outside of the flange 13. Rods 11 enter in the holes 7 of the adjusting disk. Hammer crusher works as follows. Through chute 2, the crushed material enters the body 1, where it gets hit by the rotating hammers 12. After passing several stages of crushing, the material of a given fraction is freely ejected from the crusher body. During operation, the hammers are subjected to the most intensive wear. After some time, the wear of the hammers will not allow to obtain the material of a given fraction. To adjust the working gap between the body reservation surface and the ends of the hammers, the crusher is stopped. The nuts 13 loosen, disconnect the plate 9 from the adjusting disk / 5. The working gap is set by turning the hammers 12 around the fingers 10, then moving the disk 5 until the rotation stops 8 interact with the side surface of the hammers while the fingers 10 slide along the grooves 6. The core - 11 plates 9 are rearranged into the next hole 7 of the disk 5. The nuts 13 are tightened. The discs are pressed tightly against the flanges 4. After adjusting the gap, the crusher is ready for operation.
