Critical speed is the theoretical RPM where particles stick to the scrubber shell instead of tumbling. Operating at 60–70% of this speed creates optimal cascading, maximising clay breakdown and washing efficiency without excess wear or energy waste. Learn how to calculate % critical speed and hit the sweet spot for throughput and equipment life
