Abstract:
1. An injector for a flotation cell, comprising a feed channel for feeding a fiber suspension flow to the flotation cell, a flow distribution element for distributing the fiber suspension flow fed to the injector into partial flows, a mixing apparatus for mixing air with a fiber suspension flow, and at least one air input point for sucking air to be mixed with the fiber suspension flow into the injector, wherein the feed channel, the flow distribution element and the mixing apparatus are in the injector arranged with respect to one another such that a flow direction of the fiber suspension flow in the feed channel is substantially opposite to a flow direction of the fiber suspension flow through the flow distribution element and the mixing apparatus, and wherein the flow distribution element and the mixing apparatus are arranged adjacent to and substantially directly abutting the feed channel so as to at least partially surround the feed channel.
