A reliable, accurate, and hygienic solution for conveying and dosing powders, granules, and other bulk solids. We custom-engineer every screw conveyor to the specific characteristics of your material, ensuring consistent flow, preventing bridging or compaction, and maintaining product integrity. With a focus on advanced sanitary design and ease of cleaning, our systems are the ideal choice for the food, pharmaceutical, chemical, and plastics industries.

Common Applications:

  • Food & Pharma: Accurate dosing of ingredients (flour, sugar, milk powders, spices) into mixers or packaging machines.

  • Chemicals & Plastics: Conveying plastic granules, pigments, and chemical powders.

  • Defense: Controlled conveying of propellant powders and raw materials.

  • Agriculture: Conveying grains, seeds, and animal feed.

How to Specify Your Needs:

  1. Material: What is the material? What is its bulk density (kg/m³)? Is it free-flowing, sticky, abrasive, or heat-sensitive?

  2. Capacity: What is the required conveying rate (kg/h)?

  3. Geometry: What is the conveying distance? Is an incline required?

  4. Sanitary Requirements: What level of cleanliness is required?

Material option A SS304
Material option B SS316

 FAQ

  1. Q: What's the difference between a U-Trough and a Tubular screw conveyor? A: A U-Trough is standard, easier to manufacture, and allows for convenient access for inspection and cleaning. A Tubular conveyor is a completely enclosed system, ideal for dust containment, maintaining hygiene, and conveying at an incline without material fallback.
  2. Q: My powder is "bridging" in the hopper and won't feed into the screw. What's the solution? A: Bridging is a common issue with cohesive or moist powders. We solve it by designing hoppers with steep walls and, if necessary, adding mechanical aids like a vibrator or a slow-moving agitator arm that breaks the bridges and ensures a consistent flow into the screw.
  3. Q: How do you prevent the powder from compacting or being damaged in the conveyor? A: We custom-design the screw geometry for the material. For example, using a variable pitch screw (where the pitch increases towards the outlet) ensures the trough remains uniformly full and prevents compaction. For fragile materials, we use a lower rotational speed and a gentler "ribbon" style screw.
  4. Q: Can a screw conveyor be used for accurate dosing? A: Absolutely. When used as a "feeder," we equip the screw conveyor with a Variable Frequency Drive (VFD) for precise speed control. With proper calibration, very high accuracy in the feed rate can be achieved, which is critical for packaging or mixing lines.
  5. Q: My current conveyor is very hard to clean between batches. How is your solution different? A: We design our systems with an emphasis on rapid cleaning. This includes quick-release clamps for the cover (instead of bolts), a quick-demount drive-end for sliding the screw out, and smooth internal finishes with no "dead spots" where material can accumulate.
