Rotary accelerator device for granular material, has block made of white iron alloy part, accelerator unit has greater tensile strength after thermal hardening, and strengthening unit has arrangement to attach support

摘要

The device has a block made of a white iron alloy part provided with a strengthening unit (7). The unit has an attachment side, and a transversal side with an attachment surface. The attachment side and the surface form an accelerator unit (1). The unit (1) has greater tensile strength after thermal hardening of the accelerator unit. The unit (7) is provided with an attaching arrangement to attach a support unit.
