  • Apparatus for crushing waste products and method of operating the same
    Publication number: 20020056770
    Abstract: A apparatus for crushing waste metal products includes a rotor having a crushing device on a periphery thereof and a casing enclosing the rotor. The casing has an inlet and an outlet for products to be crushed. An exhaust gas from the casing is partly returned to the inlet of the casing by a circulator. The rest of the exhaust gas is ventilated and processed by an exhaust processor. An oxygen concentration is monitored in a gas pathway of the circulator to control the gas concentration in the casing. If the oxygen concentration is high, a water shower sprays into the casing.

  • Method of separating iron sheets from wasted iron products
    Patent number: 6364117
    Abstract: This invention pertains to a method of separating iron sheets from washed iron products. The method includes the following steps: crushing wasted iron products into pieces; transporting the crushed pieces on a conveyer; and separating iron sheet pieces from the crushed pieces on the conveyer by virtue of a magnetic separator placed over the conveyer, wherein the iron sheet pieces staying on the conveyer in a standing state are selectively subjected to an upward force. By applying the upward force to the sheet-shaped iron pieces staying on the conveyer, the balance between magnetic and gravitational force is lost and the iron sheet pieces are smoothly attracted by the magnetic separator.
