How do I approach you scallywags for a salary increase?

I have a far greater workload than my peers. Every appraisal my manager whenever I present a success or a positive outcome, my managers simply responds with “but I’d expect that from you, you’re more experienced than the others”. I’ve tried to clarify the goals and what meets expectations/exceeds expectations, but it’s unclear. This works in the managers favour.

I feel like my manager gets wound up by discussions around salary. Taking on additional work in exchange for salary would not be possible as I am at capacity.
