IMPACT PLATE FOR ROTOR OF IMPACT CRUSHER AND ROTOR OF IMPACT CRUSHER

摘要

PROBLEM TO BE SOLVED: To provide an impact plate which has a cross section being as simple as possible, is relatively thin in an impact edge area, but resists to strong force by an impact effect, has an appropriate abrasion curve, and reduces costs during operation. SOLUTION: The cross section of an impact plate 1 has a basic shape of a double-trapeziodal shape having a long base line (a) as a symmetric axial line 2. The back 5 of the impact plate 1 corresponding to the length of each trapezoid is oriented perpendicularly to the symmetric axial line 2 to form a flat surface 6 in the height 7 direction of the impact plate 1. A contact surface 9 to be formed on the back 5 of the impact plate 1 extends in the longitudinal direction of the impact plate 1 and is formed by a groove-shaped recessed part 8 to be arranged at the height of the symmetric axial line 2.
