Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus that crushes stones, wears away sharp edges, and takes out the stones, and also separates the stones into two or more blocks and takes them out.

It is known to incorporate large numbers of pebbles into concrete blocks to improve the appearance of the block surface.

In known blocks, the mixed pebbles are polished and used. The reason for this is that the surface of the polished pebbles is shiny and rounded, making the appearance of the block surface even better.

Previously, the material had to be crushed and then passed through a Gokenreki machine, which not only took a long time, but also increased costs.

Furthermore, conventional equipment caused problems with dust and created a poor working environment.

In addition, in conventional equipment, polishing and classification were performed using separate equipment.
In order to obtain stones classified by particle size, they had to be passed through a classifier, further increasing costs.

SUMMARY OF THE INVENTION The object of the present invention is to improve the above-mentioned drawbacks, and to provide an apparatus that can sufficiently crush, polish, and classify with just one machine, and that does not generate dust.

Hereinafter, explanation will be given with reference to figures. FIG. 1 is a sectional view showing one embodiment of the present invention, FIG. 2 is a sectional view taken along the line A-A in FIG. B-
It is a sectional view of B.

A rotor 2 is eccentrically placed inside a shell 1 consisting of a rotating drum. A supply port 3 for raw stones is provided at one end of the shell 1, and a discharge port 4 for discharging crushed stones is provided at the other end. There are multiple Rikers 5 on the inner surface of shell 1.
is provided, and the liner 5 is slightly twisted in a helical shape to perform a stone feeding action. A liner 6 is also provided on the outer periphery of the rotor 2, and the liner 6 may be linear or spiral.

The liner 5 is cut short at the discharge D 4 (1411), thereby forming a rubbing space 7, which will be described below, near the discharge opening 4 of the shell 1.

The rubbing space 7 is an area where stones are rubbed together without crushing, thereby smoothing the surface of the stones. This reduces the chance that fine powder will be formed from the stone later, but
A large amount of broken powder is generated in the rubbing space 7.

The discharge port of the shell 1 is connected to the l'ilA part of the shell 1, and the mesh shell 8 is connected thereto. The mesh shell 8 has a large number of openings 92, and as will be described later, stones are classified into stones passing through the openings 9 and stones falling from the ends of the mesh shell 8.

Referring also to FIG. 2, which is shown in the A-A 1ffT plane view of FIG. "113 is discharged [14] and is injected into the gravel body 14 that covers the mesh shell 8. The air inlet 11 is directed toward the stones M that are being rubbed together, and the rotation of the shell 1 causes the stones M to be shifted to one side. The suction port 13 is not limited to the embodiment, but may be opened directly above the rubbing space 7, or below the body 14. nid: C-)1
5.16 is provided to transport the crushed stones to belt conveyor 1
Drop it onto 7°18. In this case, the chute 15 receives the stones that have passed through the opening of the mesh shell 8 and sends them onto the belt conveyor 17, and the sheet 16 receives the stones that have fallen from the bottom of the mesh shell 8 and transfers them onto the belt conveyor 18.
It is composed of things that are sent upwards. The raw ore to be crushed is sent from the belt conveyor 19 to the sheet 16 and introduced into the supply port 3 of the shell 1. As shown in FIG.
Referring to this, the eccentricity between the shell 1 and the rotor 2 is biased downward and toward the side where the stone M is lifted upward by 10 rotations of the shell, and the center of the shell 1 is ol+
The center of the rotor 2 is 01.

The operation of the present invention configured as described above is as follows.

The raw stone introduced into the shell 1 must be 50 mm or less, and it is crushed to at least 25 mm or less.

First, the introduced stone M is lifted upward by the liner 5, and then falls. Then, it enters the gap between the liner 5 and the liner 6, is forced together, and is crushed. The liner 5 has a slightly spiral shape, so it is repeatedly lifted upward and dropped until it reaches the discharge port 4 little by little.
Go to the side.

The stones that have progressed to the grinding space 7' are ground together here and their surfaces are scraped. However, a large amount of fine powder is generated when the sews are put together, and this powder is mixed into the shredded cloth. Therefore, air is sent by a blower 10 and is blown onto the stone M through an air blowing port 11. Then, the fine powder flies up and spreads inside the cover 14 and the shell 1, and the dust collector 12 absorbs the air and the fine powder inside the cover 14 from the suction port 11 like a blower 1o. No fine powder will come out of the body 14 when you suck it. The stones that have been ground together are transported from the discharge port 4 to the mesh shell 8). The opening 9 of the meso sea shell 8 became 5 mm, and a stone of less than 5 mm fell through this opening 9.
-415, is sent to a predetermined upper level via the belt conveyor 17.

Also, stones with a size of 5 to 25 mm are lowered from the end of the mesh shell 8 and placed on the sheet 16. It is sent to a predetermined process via a belt conveyor 18.

In the above, the predetermined process refers to a washing process, an underwater polishing process, etc., which are adopted as necessary.

As explained above, according to the present invention, a seam-aligning space is provided in the crusher, and crushed stones can be aligned in this space to take the corners of the stone surface. In addition, air is blown onto the stones during the grinding process to stir up fine powder, which can be sucked up by a dust collector, so that no fine powder is mixed into the stone being removed.

Further, by providing a mesh shell, crushed stones can be classified and taken out.

Ru.

In addition, it is also possible to classify particles into a larger number of particle sizes by changing the diameter of the opening provided in the mesh shell in the axial direction.
