Whether you are formulating complex NPK fertilizers, specialty minerals, or chemical powders, your granulation line lives or dies by the performance of its granulation drum. Capacity must be high, granule size must be tight, your shell and inner linings must withstand hot, abrasive slurries around the clock—often in corrosive plant atmospheres. Drawing on years of process know‑how and the hard data in our latest specification sheet, our granulation drums deliver a rare combination of industrial‑scale throughput, fast & precise granule formation, and rugged construction that minimizes the lifetime cost of ownership. ​

Key Features and Benefits:

• Built to Survive Heat, Corrosion & Abrasion:
  A forged‑steel riding ring carries a 15 mm‑thick carbon‑steel shell lined with overlapping EPDM rubber sheets; this composite approach absorbs impact, resists chemical attack and prevents product from wedging behind the liner. The drum easily handles 50 – 175 °C process temperatures and abrasive duty cycles measured in decades rather than years. Automatic grease‑spray lubrication keeps the gear mesh healthy with virtually zero manual intervention.
• Uniform Granule Size in Minutes:
  Internal EPDM‑rubber lifter plates, a 3% drum slope and a controlled 10–15% filling factor keep material in the bed for just 8–10 minutes—yet still yield up to 70–80% of granules in the target band. The result is fewer fines, better drying efficiency, and a premium‑looking product that commands a higher market price.
• Industrial‑Scale Throughput—24 / 7 Duty:
  Our drums are sized for your design capacities, driven by a heavy-duty spur-tooth ring and pinion gear set, and supported on double-row trunnion rollers. Continuous 24‑hour duty means fewer change‑overs and more product out the gate every shift. An auxiliary emergency motor allows slow rotation during maintenance so the shell never bows under thermal load.
• Sustainability in Focus:
  The advanced drum granulator design minimizes dust generation and waste, contributing to a cleaner, more eco-friendly production process that aligns with modern environmental standards.

Smart Design Details That Pay Off

• Top & Side Inspection Doors – quick visual checks or manual clean‑outs without disassembling the feed or discharge chutes; swing‑bolt closures let one technician break‑in, reseal, and restart in minutes—no crane required.

• Steep‑Angle Inlet & Outlet Chutes (60–65 °) – mirror‑polished liners and self‑draining geometry virtually eliminate caking, so even tacky slurries slide through without manual poking or purge air.

• Dedicated Air & Vapor Handling Ports – pre‑drilled, gasketed manifolds simplify “plug‑and‑play” tie‑in to scrubbers or condensers, keeping dust and NH₃ capture within tightening emission caps.

• Modular Internal Kits – bolt‑on lifters, spirals, or lump‑kickers can be swapped in a single shift; the standardized hole pattern means upgrades cost hundreds, not thousands.

• Intelligent Condition‑Monitoring Ready – vibration and temperature pad mounts are pre‑installed, so adding IIoT sensors for predictive maintenance is as easy as threading in an M16 stud.

Why Choose Our Drums?

High throughput keeps unit operating cost down; precise granulation lowers recycle streams and boosts downstream dryer efficiency; and the over‑built shell, liners and drive components slash unplanned downtime. Add in user‑friendly maintenance points and automated lubrication, and you get a drum that frees your operators to focus on optimization instead of firefighting. In short, our granulation drums turn raw feed into saleable, uniform granules faster and more reliably.
