Step 2 : Proportioning Blending & Raw Grinding. The raw materials are analyzed in real-time using cross-belt analyzers and in the plant laboratory, blended in the proper proportion, and then ground even finer. Plants grind the raw materials with heavy, wheel-type rollers that crush the materials into powder against a rotating table.Plants absorb measurable concentrations of Si ranging from 0.005 to 11.3%, and this level will vary by plant species. A minimum silicon level in plant tissue is needed to suppress disease and may range between 0.33 to 0.5 times more than the control plant. Once that level of Si in plant tissues has been obtained, disease suppression will ...
