1) synchronization and into the material method. Composition and mixing of liquid and water glass is relatively stable, reaction, to ensure the stability of product quality.

2) synthesis process of continuous slurry. The stability and the synthesis quality, simplifies the operation, reduces the labor intensity.

3) joined the directing agent. To shorten the crystallization time, improves the production rate of raw materials and equipment production.

4) separation of vertical filter developed by introduction and cooperation of slurry, which dropped from 38% to 24% of the liquid in the cake, can significantly reduce the washing step load, more conducive to drying operation to reduce the energy consumption. Main equipment: vacuum belt filter.
