Description

Waste tire pulverisor

The present invention relates to a waste tire crusher, and more specifically, to a crushed block of a desired particle by crushing the waste tire several times in a large time in a set of large tire mills in a short time, and then to press blocks and construction materials. It relates to a waste tire crusher that can be used as a recycled product.

In general, tires mounted on the wheels of automobiles need to be replaced with new tires because they do not function as tires, such as the circumference of the tires worn out for a certain period of time, resulting in reduced braking force. In Korea, about 10 million of these tires are currently occurring, but the number of waste tires discarded due to the rapid increase in automobiles is increasing significantly.

Such waste tires are polluted to the environment and cause pollution by being left in the yard or incinerated, and thus, many years ago, studies are being actively carried out to recycle them to a certain size.

Although a number of waste tire grinders have been proposed in the past, most of these waste tire grinders transfer a hopper for receiving waste tires, a rotary cutter installed in the lower region of the hopper, and a pulverized product pulverized by the rotary cutter. A conveyor and the like. Therefore, when the tire is supplied to the hopper, the waste tire is cut into small particles of pulverized product by the rotary cutter.

In particular, in order to remove the steel wire contained in the waste tire, it is necessary to cool the waste tire in a brittle state and then cut and crush the waste tire using a device having two grinders, which are seen as dies and punches. It is included.

However, the conventional waste tire crusher as described above has a lot of inadequate points such as simply crushing the waste tire during the crushing process, and it is not efficient to grind. There is a disadvantage. In particular, the conventional waste tire shredder has a closed end that is less efficient because the steel wires are entangled when the steel wire contained in the waste tire is separated from the waste tire when the waste tire is crushed. In this case, a separate machine is used, but at this time, high heat is generated, and thus, the quality of the crushed product (rubber) is lowered, and only a small amount of the crushed product is discharged due to the high temperature.

Accordingly, an object of the present invention is to provide a waste tire grinder capable of grinding a large amount of waste tires into grinding particles of a desired size in a short time.

Another object of the present invention is to provide a waste tire crusher that can remove the steel wire when crushing waste tires and separate them into steel wire and waste tire crushed products, respectively, to increase the versatility of recycling.
