Dry to slurry mixing systems for Industrial and Municipal applications: Sodimate engineers custom mixing tanks for various slurry solutions ranging from 2% to 30%. Typical slurry solutions include calcium ( hydrated lime or quicklime ), powdered activated carbon (PAC ), sodium bicarbonate (soda ash), potassium permanganate and clay.
The invention relates to the technical field of wet desulphurization, and discloses a preparation method of high-density limestone slurry, which comprises the following steps: (1) Limestone enters a limestone storage bin through a discharge hopper and a feeder, and is conveyed to a ball mill from the limestone storage bin through a weighing belt …
The incoming flue gas is sprayed with a slurry containing finely-ground limestone particles. The limestone for the CWLP scrubbers contains greater than 95% calcium carbonate (CaCO 3 ) content.
Neither lime nor limestone dissolves well in water and therefore, both are pumped in slurry form to the scrubber tower. Lime slurry is more alkaline, having a pH of 12.5 while …

It is the acid generated by absorption of the SO 2 into the liquid that drives the limestone dissolution process. Equation 2: CaCO 3 + 2H + Ca+2 + H 2 O + CO 2 ↑. Equations 1 and 2, when ...
Neither lime nor limestone dissolves well in water and therefore, both are pumped in slurry form to the scrubber tower. Lime slurry is more alkaline, having a pH of 12.5 while limestone slurry is roughly neutral. A lime based system will therefore add more lime when pH drops below 12 and a limestone based system will be controlled around 6. …
The device comprises a limestone powder bin, a powder bin discharge port is communicated with a limestone slurry tank feed port through a feed pipe, a slurry stirrer is arranged at the top of the limestone slurry tank, a water injection port at the top of the limestone slurry tank is communicated with a water injection mechanism, a liquid level …
Selection of the appropriate material of construction depends upon the reagent chemical properties (e.g. sulfuric acid) or slurry abrasiveness (limestone slurry). Our Lime Slaking and Limestone Grinding Systems incorporate horizontal, roller mounted, wet grinding ball mills and wet scrubbers to extract steam away from the dry product.
If limestone consumption must be increased to improve SO2 removal, the reagent preparation and dewatering systems may be undersized. In most cases, higher SO2 removal requires a finer grind than what older systems were originally designed to achieve. The standard grind on modern wet FGD systems is 95% passing through a 325 mesh.
