Description

The above target is achieved by the fact that a hammermill for grinding vegetable syrups, mainly a block comprising a housing, a classifier with a rotor with hammers inside, the actuator is provided with plates; inserted one into the other with the possibility of their displacement by the regulator. The latter is made as a two-arm lever pivotally connected with an internal perforated cylinder, and a rotary washer attached to the rotor and aligned coaxially with it. . : FIG. 1 shows a sectional crusher; in fig. 2 - section aa in figure 1

Inside the crusher body 1 there are rotor 2, - with suspended hammers 3 and rigidly attached to - by a classifying device consisting of cylinder 4, inside of which cylinder 5 is inserted, adjacent to the outer surface of cylinder 4 are padded rotor 6. Regu; lyre The device for displacing the cylinder 5 relative to the cylinder 4 includes a double-arm lever 7 and a rotary washer 8. Between the perforated cylinder 5 and hammers 3

. fixed plates 9 mounted in the lid 10 of the housing 1 are installed. The hopper 11 is attached to the same lid 10. The lower part of the housing 1 is designed as an unloading /. pipe 13. The rotor 2 of the crusher is driven in rotation by the engine 12.

Crusher works as follows.

From bunker 11, the raw material to be ground is continuously fed into

; the central part of the rotor 2, is involved in the rotational motion and under

. the action of centrifugal forces moves to the cylinder 5. When this happens, the grinding of raw materials occurs due to blows of hammers. The resulting smaller particles of the raw material are ejected by centrifugal forces through the partially blocked perforations of the cylinders 5 and 4 and are removed from the crusher through the discharge port 13. The ground mass is accumulated on the inner surface of the housing 1 with blades that move it to the spout 13. More Large particles that have not passed through the perforations of the cylinders 4 and 5 are removed from the inner surface of the cylinder 5 by fixed plates 9 and are sent last to the zone of rotation of the hammer RV 3 for additional grinding.

To ensure optimum particle sizes of the crushed mass. Adjust the working dimensions of the perforated drum consisting of cylinders 4 and 5 by rotating cylinder 5 relative to cylinder 4. After the crusher remains open, the washer 8 rotates two shoulders PYag 7 connected to cylinder 5.

Performing a crusher according to the invention allows it to increase its productivity and the quality of the finished product. .

Claims (2)

 1. Hammer crusher for grinding, plant material, mainly a block containing a housing, a classification device with a rotor located inside it with hammers, a drive characterized in that, in order to improve the performance and quality of the finished product, the crusher is equipped with plates fixed for inside the classifier, the latter being made in the form of two horned cylinders, inserted one into the other with the possibility of their mutual displacement by means of an adjusting device Yeni. 2. The crusher according to claim 1 is distinguished by the fact that the adjusting device is made in the form of a double-arm lever pivotally connected to the inner perforated cylinder, and a swivel washer attached to the rotor and coaxially aligned with it.
