In wet ultra-fine grinding of the limestone slurry with a given additive amount of a dispersant (i.e., Dispersant S40), the slurry from an initial feed to a final FP slurry (a discharge slurry where the grinding operation is automatically terminated by a safety control device due to poor slurry flowability) is transformed through different ...
2018-12-3 · The limestone is crushed at the quarry, mixed with water to form a slurry, and pumped through the pipe. We would like to minimize the operating cost, which is primarily determined by the grinding power and the pumping power. The following specifications are given, L = length of pipeline = 15 miles W = flowrate of limestone = 12.67 lbm/sec
The production of new surface at the later grinding is governed by the viscosity of the slurry.
