<p>A rotor for a vertical shaft impact crusher comprises a vertical wall segment (20) having a first wall portion (20a), which is tangential to the rotor (1) and is located adjacent to the periphery of the rotor (1), and a second wall portion (20b), which is angled in relation to said first wall portion (20a) and extends from the first wall portion (20a) into the rotor (1). The second wall portion (20b) comprises a first section (80), which extends from the interior of the rotor (1) towards its periphery and forms an obtuse first angle (S) with said first wall portion (20a), and a second section (84), which connects the first section (80) and the first wall portion (20a). The second section (84) and said first wall portion (20a) form a second angle (T), which is smaller than said first angle (S), and at least one pocket (88) for retaining material.</p> |
