Photography — Surface
A Si-Tec® feed disk out of a Cemco 70, wear face up, next to the shoes it ran with. The wear pattern the disk produces on the shoes is what the story is about.
Measured on site
Feed disk wear life improved 35%, while shoe wear life improved by 41%, with an increase of 1,469 tons produced.

What these numbers are not.
A wear part that lasts twice as long in Tennessee sandstone can do nothing of the kind in Idaho RAP, because the rock, the tonnage, and the geometry are different. Nothing here is a warranty and nothing here is a specification. What SI will do is measure your part in your circuit and put the numbers against the ones you have now.

Service life in hours or tons, the feed material, and photographs of where the wear actually is. That is enough to say whether Si-Tec® changes anything in your circuit.
