Rector Ahmed Bawa said disciplinary hearings would determine their fate.
“These students, who were part of the violent protests, have been charged in accordance with the university rules and policies.”
Spokesman Alan Khan was unable to say how many students had been suspended.
Lectures at the university’s Durban campuses were suspended following protests on Tuesday, but these would resume on Thursday. The Pietermaritzburg campus was unaffected.
On Tuesday, the university obtained an interim high court interdict preventing students from protesting within 100 metres of its premises.
The protests erupted earlier this year over the non-payment of fees. Several students were initially not allowed to register pending the payment of fees.
The university and the student representative council reached an agreement to end the protests two weeks ago. Protests, however, flared up again on Monday.
