The base of the large metal crusher equipment is narrow at the top and wide at the bottom, with good stability. The internal structure of the machine is connected by a shaft with 4-7 fixed cutterheads. The fixed blade is S-shaped and can be used twice. The fixed blade plays a role in forced feeding and forced crushing in the metal crusher. The hammer head of the metal crusher is forged from train wheel steel, with good density, economy, and durability. During the crushing process, the metal material rotates with the rapid operation of the hammer, and after a short period of time, it is pounded and rubbed together. The finished particles flow out from the bottom screen, and at the same time, a part of the paint and impurities are blown away by the dust collector, making the flowing metal particles clean. The bottom is a slanted plate feeding structure, which has fast discharge and no material storage. The whole machine design is perfect, never getting stuck or clogged.
