The pulverizing system mainly comprises drying equipment, equalization treatment equipment and a pulverizer. The specific embodiments will be described in detail as follows.

[0023] Referring to Figure 1 The drying equipment of the embodiment mainly comprises an oven 3. The oven 3 can mainly adopt an energy-saving oven 3 including hot air or far infrared heating technology. The recycled discarded garment fabric is sent into the conveying device 1 by other mechanical equipment or in an automatic manner. Part of the conveying device 1 is arranged in the middle part of the oven 3. The conveying device 1 runs at a uniform speed. The discarded fabric is dried by the conveying device 1 from the inlet to the outlet. The temperature of the oven 3 is generally tens of degrees. The conveying device 1 adopts an oven industrial conveying belt.

[0024] Referring to Figure 3 The equalization treatment equipment comprises a cutting tool 5 with a relatively thin thickness. The cutting tool 5 is provided with a plurality of sharp teeth. The cutting tool 5 is provided with a second conveying belt 4 running synchronously on both sides. Since the cutting tool 5 is very thin, the gap between the adjacent second conveying belts 4 is very small. When the discarded garment fabric passes through the cutting tool 5, the discarded garment fabric is cut and divided into small pieces of cloth and is conveyed to different positions of the pulverizer 6 through different channels, so that the equalization treatment of the cloth is realized.

[0025] Referring to Figure 4As shown, the grinder 6 can adopt the grinding device in the prior art, and the embodiment mainly adopts a rolling cutter grinder, which comprises mutually matched rotating shafts 601, a plurality of cutters 602 are arranged on the outer wall of the rotating shaft 601 at equal intervals, the cutters 602 on the adjacent rotating shafts 601 are staggered, an inclined surface 603 is arranged on the outer wall of the machine case adjacent to the rotating shaft 601, a cutter groove 604 is arranged on the inclined surface 603, and the cutter groove 604 is matched with the cutter 602 on the adjacent rotating shaft 601. The rotating shaft 601 is driven by a motor 605, and the motor 605 is further connected with a gear speed change mechanism.

[0026] In the above embodiment, with reference to Figure 1 and Figure 2 As shown, the entrance of the oven 3 is provided with a spreading device 2 for spreading the waste clothing fabric 9, and one specific embodiment is that the spreading device comprises a cloth roller 201, which is arranged above the conveying belt of the conveying device 1 and is used to limit the waste material higher than the cloth roller 201 from entering the oven 3. In most cases, the waste material is poured onto the conveying device 1 by a forklift or other equipment, and also includes unloading the garbage on the ground near the conveying belt of the conveying device 1, and the waste material is conveyed by pushing it into the ground area of the conveying belt. These loading methods make the distribution of the waste material on the width and height of the conveying belt uneven, and in fact, the distribution of the waste material in the length direction of the conveying belt is also uneven. If it is directly conveyed into the oven 3, the heat accumulation of the cloth is uneven, and in the case that the drying time is only a few minutes or tens of minutes, it is often not fully dried. The ideal situation is to evenly spread the waste material on the conveying belt. The embodiment adopts the cloth roller 201 to limit the high cloth from entering the oven 3, and under the action of the cloth roller 201, the high part of the cloth is transferred to the length and width direction of the conveying belt, so that the waste material can be more evenly spread on the conveying belt and enter the oven 3 for drying.
