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 .

The hardness of normalizing heat treatment reaches above HRC55. The thickness of the lining plate at the bottom of the chute is 80mm, and the liner at both sides of the chute are 40mm and 20mm. The total number of the whole set of SAG mill chute liners is 25, and the weight is about 3.1t.
Reduce downtime by mechanically driving mill liner handler into place for easy bolt on action. Prevent injury and strain by automating the mill relining process with mechanized liner manipulators. Once inside the mill, liners are delivered by a 3 axis crane and 4 axis manipulator

C. Set up feed chute and liner handling equipment for fast, easy movement. Considerable time can be saved with fast mill opening and liner handler set up. Tools required to speed up this job i.e., jacks, hoists, dollies, monorail, tugger, etc., pay for themselves quickly in improved mill availability.
3.2.1 Primary FAG/SAG Mill Circuit Ore is withdrawn from the conical stockpile via 2 of 4 apron feeders and delivered to the primary mill feed conveyor. A semi automatic ball loading system is available to load steel balls onto the mill feed conveyor. The fresh feed ore size detection is done via a Lynxx optical size analyser.
