Problems solved by technology

[0002] Plastic pulverizers are widely used in the plastic manufacturing industry. The raw materials of existing plastic pulverizers are generally from recycled plastic waste, and there are many impurities. Non-metallic impurities can generally be removed clearly by liquid, and metal impurities are often mixed into plastic raw materials, which often block injection molding. The nozzle of the grinder will damage the blade of the grinder and scratch the cylinder of the machine, which is very harmful. At the same time, the plastic grinder in the prior art has only one set of crushing knives, which directly cuts and grinds the plastic, and the crushing is not sufficient. The blade is seriously damaged, and the blade needs to be replaced frequently; at the same time, in the prior art, there is only one feeding barrel, and the plastic raw materials fall from the height, scattered and scattered, with loud noise and much dust

Abstract

The invention discloses a damage-proof crushing machine capable of separating metal impurities. The damage-proof crushing machine capable of separating metal impurities is characterized by comprising a hobbing cutter set (10), a roller cutter set (20), a first feeding cylinder (30), a second feeding cylinder (80), powder isolation plates (40), a screen (50), a discharging cylinder (60), a box (70), a metal separator (100) and a motor. According to the damage-proof crushing machine capable of separating metal impurities, metal particles can be separated from plastic particles, and the service life of blades of the plastic crushing machine is prolonged; meanwhile, the hobbing cutter set and the roller cutter set are used in combination for plastic crushing, so that abrasion of the hobbing cutter set is reduced, and the service life of the cutter sets is prolonged; and the roller cutter set is sealed through the two feeding cylinders, so that dust is reduced, and noise is lowered.
