Product Specifications

Technical details and manufacturing context for Prilling Head / Bucket

Definition

A prilling head or bucket is a critical component in a prilling tower system used primarily in chemical manufacturing. It receives molten material (such as urea, ammonium nitrate, or other chemicals) and distributes it through multiple nozzles or perforations to form uniform droplets. These droplets then fall through the tower's cooling chamber, solidifying into spherical granules or prills through controlled cooling and solidification processes. The prilling head is typically constructed from corrosion-resistant materials such as stainless steel (316L/304) or special alloy steels, with corrosion-resistant coatings applied as needed. Key parameters include operating pressure (1.0–1.6 MPa), operating temperature (150–300°C), throughput capacity (5–50 t/h), hole diameter (0.5–3.0 mm), number of holes (100–1000), material grade (316L, ASTM A240), surface roughness (Ra 0.8–1.6 μm, ISO 1302), weight (50–200 kg), connection size (DN50–DN200, DIN 2633), and tolerance on hole diameter (±0.05 mm, ISO 2768). These values are reference ranges and must be verified for the specific model and application. The prilling head is a component, not a standalone product, and its selection depends on the chemical process, desired prill size, and tower design. It interfaces with the feed system and the tower structure via flanged connections. When selecting or verifying a prilling head, confirm the operating conditions, material compatibility, and dimensional specifications with the legal manufacturer or supplier. Regular inspection for wear, corrosion, and blockage is essential to maintain performance. Failure to operate within specified limits can lead to poor droplet formation, reduced product quality, or equipment damage.

Working Principle

The prilling head operates by receiving pressurized molten material from the feed system. The material flows through distribution channels within the head to multiple nozzles or perforated plates. As the material exits through these openings, surface tension causes it to form droplets of consistent size. These droplets fall freely through the tower, undergoing cooling and solidification to form uniform prills. The number and diameter of the holes determine droplet size, while the operating pressure and temperature affect flow and solidification. Uniform distribution is critical for consistent product quality.
