    Each deck is 1.2 m wide by 1.5 m long, separated by a 13 mm space that defines the pulp channel. In a typical operation, feed is distributed to all decks for up to 35 min, when the flow is briefly interrupted and the table tilted to wash off the concentrate. The cycle is the repeated. This concentrator can recover over 60 % of 10 fan particles.
