Industrial Blenders

Batch and continuous mixing equipment for powders, granules, and paste-consistency materials. Uniform blending achieved through mechanical agitation inside a horizontal trough or shell — mixing times typically 3–15 minutes per batch.

Ribbon Blender — Horizontal U-trough with inner and outer helical ribbons rotating on a central shaft. Outer ribbon moves material inward, inner ribbon moves it outward — creates cross-flow mixing pattern. Most versatile design for general dry powder blending.

Paddle Blender — Multiple flat or angled paddles on a central shaft provide gentle tumbling action. Lower shear than ribbon type — preferred for fragile materials, granules, or products where particle size integrity must be maintained.

Plough-Share Blender — Plough-shaped mixing elements mounted on a central shaft inside a cylindrical drum. High-intensity mixing with optional chopper blades for breaking lumps. Fastest mixing time — suited for cohesive powders that resist conventional blending.

Trough & Shell Design

Ribbon and paddle blenders use U-shaped troughs with close-tolerance clearance between ribbon tips and trough wall. Tighter clearance means less dead zone and better mixing — but requires precise fabrication.

Trough construction options:

• Mild steel with food-grade epoxy lining for non-corrosive chemicals
• SS 304 for food, pharmaceutical, and mildly corrosive applications
• SS 316 for aggressive chemicals and chloride environments
• Polished interior (Ra < 0.8 μm) for pharmaceutical-grade cleanability

Drive & Sealing

Shaft-mounted gearbox drives with VFD for speed control. Shaft seals prevent material leakage and contamination ingress — packed gland seals for dry powders, mechanical seals for wet or pressurized applications.

Bearing housings are outboard-mounted to keep lubricant away from the product zone. This is critical for food and pharmaceutical applications.

Discharge & Integration

Bottom discharge options:

• Butterfly valve — fast opening, good for free-flowing powders
• Slide gate — positive shut-off, handles heavy materials
• Bomb-bay doors — full-width opening for rapid batch discharge

Blenders integrate with upstream weigh hoppers for batch dosing and downstream conveyors or packaging lines for continuous operation.

Commissioning

• Trough alignment and shaft runout verification
• Seal installation and leak test
• No-load rotation check for ribbon/paddle clearance
• Test batch with representative material to verify mixing uniformity
• Sampling protocol establishment for quality control
