The action was taken on Tuesday after around 450 students gathered on the campus demanding their expulsion for allegedly posting 'anti-national' slogans on Facebook and Instagram, Registrar of the University RK Khare said.
The protesting students threatened to leave the institute if the Kashmiri students were not expelled, he said.
"We had to suspend the Kashmiri students to pacify the protesting students and stop them from leaving," he said.
He said the matter is under investigation and stern action will be taken against those found guilty.
