Abstract
A transfer or distribution chute for conveying bulk material by gravity flow includes an elongated chute casing defining a flow path for bulk material and a wear-resistant lining arrangement covering at least part of a flow path facing an upper side of the elongated chute casing. The wear-resistant lining arrangement includes a perforated plate affixed to the chute casing and has a plurality of perforations through which wear-resistant inserts having a body and an enlarged base are fitted in the perforations from a side opposite the flow path, such that their body protrudes through the perforation within the flow path, and their enlarged base abuts the borders of the perforation from the side opposite the flow path on one side and is held in place by the chute casing on the other side.
