The Trough Mixer is a horizontal groove-type blending machine designed for dry and wet powder mixing across industries, valued for its high uniformity and easy operation. Its U-shaped trough (made of 304 stainless steel, thickness: 3mm) and dual ribbon agitators (helical design) ensure 360° material turnover, achieving uniform mixing in 5-10 minutes (depending on material type). Available in multiple capacities (50L, 100L, 200L, 300L, 500L), it features a hydraulic-driven trough tilting system for easy discharge and 304 stainless steel construction for hygiene and durability—meeting FDA, GMP, and CE standards. The U-shaped trough has a rounded corner design (R5 radius) that eliminates dead corners, ensuring 100% material contact with the agitators and reducing residual material to less than 0.1% per batch.

Dual ribbon agitators (inner + outer) rotate at 24rpm, creating a counter-current mixing effect that moves materials from the trough ends to the center and back. This ensures consistent mixing even for materials with different densities (e.g., light talc powder + heavy calcium carbonate), achieving uniformity of ±0.3%—critical for pharmaceutical and food applications.
50L to 500L working volumes are available to match diverse production needs: 50L for small-batch food processing, 200L for medium-scale pharmaceutical mixing, and 500L for large-scale chemical blending. The 200L model handles 20-50kg/batch (depending on material bulk density: 0.4-1.2g/cm³).
A hydraulic-driven trough tilting mechanism enables 360° rotation, allowing complete material discharge without manual scraping—saving 15-20 minutes per batch compared to fixed-trough mixers. The hydraulic system uses a high-pressure oil pump (pressure: 10MPa) for smooth tilting, with a safety lock to prevent accidental movement during mixing.
The motor is wrapped with sound-insulating cotton (thickness: 20mm) that reduces noise to <75dB (measured at 1m distance), complying with OSHA and EU workplace noise standards. The agitator bearings are sealed with double-row ball bearings to minimize friction noise, extending service life to 8000+ operating hours.
Pharmaceutical industry: Mixing of medicinal powders (e.g., aspirin powder, antibiotic blends) and tablet granulates (ensuring uniform drug distribution), where dosage accuracy is critical.
Chemical sector: Blending of dyes (e.g., reactive dyes, disperse dyes), pigments (e.g., iron oxide, phthalocyanine blue), and plastic compounds (resin + filler + stabilizer) for injection molding.
Food processing: Preparation of flour mixes (wheat flour + baking powder + salt), seasoning blends (spices + MSG + sugar), and cereal blends (oats + nuts + dried fruits) for breakfast cereals.
Fertilizer industry: Blending of organic fertilizer powders (e.g., compost powder) with microbial additives (beneficial bacteria) to maintain microbial activity (the low-speed mixing avoids killing bacteria).
Ceramic industry: Mixing of clay powders with feldspar and quartz for ceramic body formulations, where uniformity affects firing shrinkage and strength.
Q: What is the power requirement for the 200L model?
A: The stirring motor is 4kw (380V three-phase), and the discharge hydraulic motor is 1.1kw—total power consumption: 5.1kw. For regions with single-phase electricity (220V), we offer a 200L model with a 5.5kw single-phase motor (slightly lower capacity: 15-45kg/batch).
Q: Can it handle sticky materials?
A: Yes, the polished trough inner surface (Ra < 0.4μm) minimizes material adhesion—suitable for sticky materials like molasses-coated cereal grains or wet clay powders. For highly sticky materials (e.g., honey-blended powders), we recommend adding a small amount of food-grade talc (1-2%) as a anti-stick agent, or upgrading to our Teflon-coated trough (optional accessory).
Q: What is the delivery time?
A: Typically 25-35 working days for standard models (50L-500L) with optional wooden packaging (IPPC-certified) for export. For urgent orders, we offer a 15-20 working days expedited production service with a 10% surcharge. Door-to-door delivery is available via international logistics providers (DHL, FedEx, or sea freight for large models), with customs clearance documents (commercial invoice, packing list, CE certificate) included.
