墨西哥采购需求：多层高频筛、高频脱水筛、线性筛、聚氨酯和橡胶筛板、金属筛网和筛板

I'm in need of a screen that can handle around 30 tph of dry crushed limestone sand. The material has a granulometry where 50% passes through a 140 mesh (106 microns), while the remaining 50% is retained between 50 mesh (300 microns) and 140 mesh. The moisture content is minimal, less than 0.5%. The end goal is to obtain the material that exceeds 140 mesh. I'm considering options like a two-deck dry screen with the top deck at 80 mesh and the bottom at 140 mesh, or possibly a multi-deck setup with several cuts leading to the final fraction at 140 mesh. Please provide your recommendations and quotations for suitable equipment that can meet these requirements.
