1. Project Overview: Clean Mixing for Food-Grade Phosphate Additives

A new customer from Russia, active in food additive (phosphate powder) production, needed to upgrade their mixing section. Their goal was to achieve high-throughput, dust-free, homogeneous mixing while maintaining strict hygiene and operator safety standards.

To support this, they decided to invest in two sets of vertical ribbon mixers, each designed for 500 kg/h mixing capacity and configured to work with a dust-free feeding station. The equipment is built to European-quality standards, targeting both performance and long-term reliability.

2. Customer Challenges: Dust, Residue, and Efficiency

Before this project, the customer faced three main issues in their phosphate powder blending:

• Serious dust during feeding
  Manual bag dumping and open feeding points created dust clouds around the mixer inlet, affecting operators and making it harder to meet hygiene and safety requirements.

• Mixing efficiency and batch cycle time
  Existing equipment had longer mixing times, making it difficult to handle growing orders and tight delivery schedules. They needed a faster mixer that could still guarantee homogeneity.

• Residue and product changeover
  Product build-up and dead corners inside older mixers caused material residue, which complicated cleaning and raised concerns about cross-contamination between different phosphate-based formulations.

3. Supplied Solution: Two 500kg/h Vertical Ribbon Mixers with Dust-Free Feeding

To address these issues, we supplied two vertical ribbon mixers, each paired with a dust-free feeding station, tailored to the customer’s phosphate powder application:

• Vertical ribbon mixer, 500 kg/h per set
  Each mixer is designed to process around 500 kg/h of phosphate powder, with a typical cycle time of 5–10 minutes per batch. This fast batch time supports high throughput while still achieving uniform blending.

• Fast mixing, no residue design
  The vertical body with a ribbon agitator provides strong axial and radial movement of the powder, delivering short mixing times and high homogeneity. The internal geometry is carefully optimized to avoid dead corners, ensuring no material residue after discharge and simplifying cleaning.

• Dust-free feeding station
  Material is loaded via a dust-free feeding station, where operators can empty bags into an enclosed hopper with dust extraction. This greatly reduces airborne powder, protects operators and keeps the mixer inlet and surrounding area clean.

• European-quality build
  The mixers are designed and manufactured following European-quality standards, with robust construction, precise fabrication and reliable components. This is especially important for food additive production where consistency and uptime are critical.

4. Performance in Operation: Stable Output and Clean Working Environment

After installation and commissioning, the Russian customer reported clear improvements in daily production:

• Stable 500 kg/h per mixer
  With each vertical ribbon mixer running 5–10 minutes per batch, the line can meet the target 500 kg/h throughput per set. Production planning has become more predictable, and the plant can respond more easily to order peaks.

• Dust-free material feeding
  The dust-free feeding stations dramatically reduced visible powder emissions during bag dumping and charging, improving the working environment and helping the customer comply with local safety and hygiene standards.

• Clean discharge and easy product changeover
  Thanks to the “no residue” mixing chamber design, nearly all product is discharged at the end of each batch. This reduces material loss and allows faster cleaning and changeovers between different phosphate formulations.

• Consistent, European-level quality
  With uniform mixing and repeatable batch performance, the customer can deliver consistent phosphate powder blends to their end users, reinforcing their positioning as a supplier using European-quality mixing equipment.

5. Key Project Data at a Glance

With these two 500kg/h vertical ribbon mixers and dust-free feeding stations, the Russian customer now runs a clean, efficient and consistent phosphate powder mixing process, matching both their production targets and their food-grade quality requirements.
