The commonly used phosphate drying equipment includes vacuum dryer, fluidized bed dryer and rotary dryer.
First, vacuum dryer
The vacuum dryer uses the volatility of water in the vacuum environment to achieve the purpose of drying by changing the pressure in the drying room. Because phosphate is very susceptible to moisture, vacuum dryers are one of the ideal drying equipment. At the same time, the vacuum dryer can cultivate a sterile environment and is suitable for the production of high-purity phosphate products.
Second, fluidized bed dryer
The fluidized bed dryer is to suspend the phosphate solid particles in the bed through the air flow, so that it can maintain a good dispersion state during the drying process, so as to achieve the purpose of drying. The equipment has the advantages of high drying efficiency, short drying time and high heat utilization rate. Due to the need for air flow heating and drying, it is suitable for large-scale phosphate production.
Three, rotary dryer
The rotary dryer uses air flow to contact the phosphate directly through rotation, evaporating the water and drying the phosphate. The equipment has the advantages of good drying effect, low energy consumption and simple structure. At the same time, because different rotating plates can be designed to adapt to different material drying. Rotary dryers are suitable for small batch phosphate production and test stages.
Phosphate drying equipment has a variety of options such as vacuum dryer, fluidized bed dryer and rotary dryer. According to the different production capacity and production environment, choosing the right drying equipment can effectively improve production efficiency and product quality.
