Learn more about the Patent Pending VERTIMILL® Retrofit Kit. VERTIMILL® slakers have been utilized as a premium lime slaker that eliminates the grit handling requirements and also produces a superior quality, more reactive, lime slurry. A typical VERTIMILL® slaker, as supplied from the factory, may allow short-circuiting of the fresh feed, resulting in large particle carry-over downstream. A small, but meaningful, percentage of the fresh feed will pass directly from the top of the slaking/grinding chamber directly into the Separating Chamber before effective slaking or grinding of the grit has occurred.
