VERTICAL SHAFT IMPACT CRUSHER FEED TUBE

摘要

A vertical shaft impact crusher feed tube (34) is adapted for protecting a rotor feeding opening (32) of a feeding funnel (14) of a vertical shaft impact crusher. The feed tube (34) comprises a tube portion (42) via which material may flow from the feeding funnel (14) and vertically downwards into a rotor. The tube portion (42) has a first width (D1) at a material inlet (50), and a second width (D2) at a material outlet (52), wherein the second width (D2) is larger than the first width (D1).
