Abstract

1. A crusher containing a loading hopper, a housing, a hammer rotor located in the crushing chamber, characterized in that the crushing chamber is formed by a deck that completely encloses the hammer rotor along the perimeter and a separator adjacent to the deck from the end surface. Crusher according to claim 1, characterized in that a second separator is additionally installed adjacent to the deck from the other end surface. Crusher according to claim 2, characterized in that the separators are made in the form of breakdown sieves. Crusher according to claim 2, characterized in that the separators are louvered.

Description

The utility model relates to agriculture and is intended mainly for grinding grain for feed purposes.

Known hammer crusher comprising a housing, a hammer rotor J crushing chamber with a deck and separator 1. Such crushers work on closed loop, characterized by a high energy intensity of the process.

The closest technical solution to the proposed utility model is a crusher containing a loading b} sker, housing J hammer rotor located in the crushing chamber 2. This crusher operates in an open cycle.

The disadvantage of this design of the crusher is the heterogeneity of the finished product according to the particle size distribution and regrinding of the material due to untimely withdrawal from the crushing chamber.

In the proposed crusher containing a loading boom, a housing, a hammer rotor located in the Kaj-iepe crusher, the crushing chamber is formed by a deck completely covering the hammer rotor along the perimeter, and a separator adjacent to the deck from the end surface. Moreover, in addition, a second separator can be installed adjacent to the deck from the other end surface, and also the separators can be made in the form of breakdown sieves or all-round ones.

The deck, completely covering the hammer rotor around the perimeter, intensifies the grinding process, as long as there is constant contact of the unmilled material with the deck. Air} Щ11-10prod test layer is inhibited by the deck and interacts with overtaking it

CRUSHER

hammer rotor. Separator; adjacent to the deck from the end surface allows you to remove the crushed material directly from the volume of the crushing chamber, where it is in suspension. 14 using the second separator, firstly, it increases the separation surface, and, secondly, it organizes the output of material on two opposite sides, which reduces the distance traveled by the particle from the volume of the crushing chamber to the separating surface. Using a louvered separator allows to intensify the air mode of the crusher and thereby improving the conditions for the exit of the crushed product from the crushing chamber.

Thus, in the covariance of these signs, the novelty of the solution is ensured and a substantial reduction in energy costs is achieved, there is no over-grinding of the material.

Danna I utility model is illustrated in the drawing.

In FIG. shows a general view of the crusher.

The crusher contains b} nker 1 adjacent to the body. 2. The hammer rotor 3 is located in the crushing chamber 4. The crushing chamber 4 is formed by a corrugated deck 5, which completely encloses the hammer rotor 3. The separators b and 7 are adjacent to the deck 5 from the end surfaces, for example, in the form of blinds. In the upper part of the housing 2 there is a filter 8, in the lower part of the housing 2 there is a device for outputting crushed material, for example, a lock gate 9.

Crusher works as follows. The Gr1 material to be crushed is loaded into b picker 1 and gravity flows into the crushing chamber 4. Once on the hammer rotor 3, the material is discarded in the direction of deck 5 and is crushed in the crushing chamber 4 when interacting with the deck and the hammer rotor. Kr} T1 parts of the material are concentrated near the deck 5 small ones are in

suspended states in the volume of the crushing chamber and through the separators 6 and 7, the air flow generated by the rotating rotor is discharged outside the crushing chamber. Filter 8 and airlock; 9 gertlepulate the internal npocipancTBo of the casing 2, which acts as a precipitator and a store of crushed material. Periodically or constantly, the finished product through the lock gate 9 is removed from the housing 2, Through the filter 8, excess air is removed.

Using the proposed crusher can reduce energy consumption and even out the granulometric composition of the finished product due to the intensification of the grinding process and the timely withdrawal of material from the crushing chamber.
