Reasons for the pulverization of urea finished product
Thread Content
The finished urea is in a shaped form beneath the conveyor belt, and its particle size meets the required standards (over 95%). However, after being stored in the bulk storage area for one or two days, the particle size of the urea decreases significantly, with some powdering occurring. I seek expert assistance to analyze the reasons behind this.
Particle pulverization is a problem that occurs in the storage of bulk materials. In addition to the crushing caused by the gravitational pressure of the piled material ； It’s the breakage caused by transportation ； The main reason is that the particles absorb moisture and become powdery. Solve storage issue: use a bulk warehouse with heating ； Try to keep it sealed to reduce air convection ； Reduce the storage cycle. In bulk storage areas, there are overhead belts and floor belts that lead outside via trestles, and this is an objective issue. Only strong management can reduce it.
1. Urine particles break apart as heat is released during their crystallization; 2. The particles absorb moisture and become pulverized; 3. The particles are crushed due to the gravitational pressure of the piled material
After urea exits the tower, there is a process of \"water migration\" that occurs; this is also the main reason for the pulverization of the material once it enters the bulk storage area. What are the environmental parameters at the LZ factory?
