This design of SAG mill feed chute lasted 9 months seeing 90,000 TPD. It is 600 brinell chrome steel. With the big liners on the bottom of the chute you need to get a Chevron cast into the top to push the feed out to the sides for the first little while and then as the chevron wears it will start to come back
