内部提升板(抄板)

Internal lifters (also called flights) are angled plates inside rotary granulation drums that lift and cascade material for uniform coating and granule formation.

技术定义与适配语境
典型 内部提升板(抄板) 会按材料、尺寸公差、适配关系和失效风险在 化学制造 中评估。

Internal lifters, commonly referred to as flights, are critical components installed along the inner wall of rotary granulation drums. These strategically angled plates lift bulk materials (powders, seeds, or nuclei) as the drum rotates, creating a cascading curtain that ensures even distribution of binding agents, coatings, or active ingredients. They optimize particle movement, enhance mixing efficiency, and promote uniform granule growth through controlled tumbling and attrition.

定义
Internal lifters, commonly referred to as flights, are critical components installed along the inner wall of rotary granulation drums. These strategically angled plates lift bulk materials (powders, seeds, or nuclei) as the drum rotates, creating a cascading curtain that ensures even distribution of binding agents, coatings, or active ingredients. They optimize particle movement, enhance mixing efficiency, and promote uniform granule growth through controlled tumbling and attrition.
工作原理
As the rotary drum rotates, the angled lifters scoop and elevate material from the bottom. Upon reaching a critical height, gravity causes the material to fall back in a cascading curtain, exposing particles uniformly to spray systems or other granules. This continuous lift-and-cascade action ensures homogeneous coating, agglomeration, and drying.

Typically 304 or 316L stainless steel for corrosion resistancesometimes carbon steel with food-grade or chemical-resistant coatings. Surface finishes range from mill finish to polished (Ra ≤ 0.8 μm) for hygiene-sensitive applications.
Height
10–25% of drum diameter
Spacing
0.5–1.5 times lifter height
Thickness
3–10 mm
Lifter Angle
30° to 60° (adjustable)
Mounting Type
Welded or bolted
Surface Area Coverage
15–40% of drum interior
标准
ISO 9001DIN 28018GMP guidelines

常见问题

How do lifter angles affect granulation?

Steeper angles (e.g., 60°) create higher cascades for intense mixing, while shallower angles (e.g., 30°) promote gentle rolling, ideal for fragile granules or coating processes.

Can lifters be replaced without drum disassembly?

Yes, bolted designs allow replacement through drum access doors; welded versions require internal welding or full drum entry.
