Description

[Detailed explanation of the invention] This invention has six crushing plates installed on the inner peripheral edge of the rotary drum, holes are made in the crushing plates, and the outer peripheral edge of the rotary drum at the position of the crushing plates is sieved at regular intervals. Concerning a shredder that is a net.

In recent years, there has been remarkable development of crushers and pulverizers in various industries, and dozens of types are commercially available.

However, these machines are for crushing or large-sized crushing, and there seem to be relatively few machines specifically for granular crushing.

For example, ball mills have a strong crushing effect, but it is difficult to obtain large-sized particles such as granules, and even if a JIYO crusher can crush large diameter objects, it is difficult to obtain large-sized objects such as granules.
/m to 10m/m, which seems to be small in terms of effectiveness for the purpose of crushing, and each machine has its advantages and disadvantages.

The crusher according to this invention is effective in obtaining granular materials with a particle size of about 0.5 to 10 m/m, and if the material to be crushed is also fed into the crusher, a particle size of 300 m/m or less is possible.

The crushed material crushed by the crusher is sieved by a sieve screen provided around the outer periphery of the rotary drum.

In other words, it is a machine that performs sieving and crushing at the same time.

The mechanical structure is simple and there are very few failures.

A more detailed explanation will be given based on figures showing examples.

FIG. 1 shows a cross section of a rotary drum 1 with two of six crushing plates 2 provided at regular intervals on the inner peripheral edge of the rotary drum 1.

The length of the crushing plate 2 is the same as the length of the rotary drum 1, as shown in FIGS. 2 and 3.

The rectangular crushing plate 2 has one long side directly fixed to the inner peripheral edge of the rotary drum 1, making an angle α of 20 to 5σ with a tangent to the outer peripheral edge of the rotary drum.

The spacing between adjacent crushing plates is approximately 150 square meters in this example, and the reason why crushing plates are provided at six locations is because it has been found through experimentation that this is the best option.

The crushing plate 2 has a large number of holes 4 through which the crushed material passes.

The hole 4 is vertically elongated as shown in FIG. 3, and gradually becomes larger in the direction opposite to the direction of rotation of the rotary drum 1 indicated by the arrow in FIG.

The width B of the hole 4 shown in FIG. 1 is equal to or smaller than the distance A between the crushing plate 2 and the inner peripheral edge of the rotary drum 1.

Otherwise, the material to be crushed that comes out of the holes 4 may destroy the sieve screen 6.

This sieve screen 6 is made of punting metal or wire mesh, and is cut out at regular intervals at locations corresponding to the crushing plate 2 on the peripheral edge of the rotary drum, and stretched there.

This sieve screen 6 is a screen for obtaining the desired size for crushing.

If the crushing plate 2 vibrates and becomes a cushion when the object to be crushed collides with the object, the crushing efficiency will decrease, so in order to prevent this, there is a vibration between the crushing plate 2 and the inner peripheral edge of the rotary drum 1. A prevention/guidance plate 5 is provided.

The crushed material is passed through the sieve screen 6 by the vibration plate 5.
be guided to.

Therefore, the vibration prevention plate 5 of the crushing plate 2 also serves as a guiding plate for the objects to be crushed.

As shown in FIG. 3, the holes 4 in the crushing plate are also provided in a portion of the crushing plate corresponding to the area between sieve screens 6 provided at regular intervals on the peripheral edge of the rotary drum 1. The material coming out of the holes 4 in this part has the effect of allowing the material to move smoothly within the drum.

The periphery of the hole 4 in the crushing plate is, for example, tungsten welded or subjected to a similar wear-resistant treatment to prevent wear caused by contact between the crushed object and the crushing plate 2.

By arranging the crushing plate 2 as described above, in the case of objects to be crushed that are particularly difficult to crush or objects to be crushed that are about 100 mm or less, an iron rod is placed in the rotary drum, and the rotation of the rotary drum 1 also rotates the iron rod. The object to be crushed is crushed by passing between the iron bars.

The sieve screen should be between 0.5 and 20 mm, and it can be set on an iron plate front frame and installed by tightening bolts, or it can be installed as is using a frame.

When the sieve screen 6 is 2 square meters or less, it is effective to use a packing.

The sieve screen 6 must be stretched so that it does not slacken.

At the input port of the rotary drum 1, a guiding plate 7 is provided in the same direction as the crushing plate 2 for guiding the object to be crushed to the back of the rotary drum.

This is to prevent the objects to be crushed from being scattered outside the drum due to the rotation of the rotary drum, especially if an excessive amount of objects to be crushed are put into the rotary drum.

There is a door 8 on the end plate on the opposite side of the input port of the rotary drum 1.
will be established.

In the event that impurities get mixed into the material to be crushed, iron that cannot be crushed gets mixed in, or when repairing the inside of the rotary drum, people enter through this door to process or take out the impurities. be able to.

Tires 9 are provided on the left and right sides of the rotary drum, and four bearing tires 10 are attached to the two tires.

Rollers for preventing the rotary drum from slipping are provided on both sides of the two tires.

Two receiving tires □-ra are connected by a shaft, and the rotary drum rotates on two sets of receiving tire rollers.

The drive is achieved by installing a sprocket on the shaft of one set of receiving tire rollers and connecting it to a motor with a chain.

As mentioned above, the crushing principle of the crusher devised is very simple.The crushing principle of the crusher is very simple. There are two ways to forcefully crush the material.

Normally, when the material to be crushed is dry, both the crushing efficiency and the sieving effect are better than when it contains water, but when the material is crushed by the crusher according to this invention, even if the material to be crushed contains water, it is not dry. The effect is not much different from that of crushing materials.
