Tapered twin shaft screw feeders for bulk solids

Ensure consistent flow and avoid material bridging challenges with a solution designed for efficient feeding and conveying, handling even non-homogeneous or difficult materials like wood chippings and soy meal.

Ensures Consistent Feeding and Discharging

The Tapered Twin Shaft Screw Feeders BU from WAMGROUP efficiently tackle the challenges of feeding and discharging non-homogeneous materials, such as wood chippings, paper, and bridging materials, like sawdust and soy. Featuring a robust design, this equipment integrates seamlessly into production lines within feed, flour milling, rice milling, and pet food industries. Equipped with a tapered inlet trough and square pitch screws, it minimizes material residue and prevents segregation. Available with ATEX, Zone 22 certification, these feeders facilitate a reliable, continuous operation. Carbon steel construction and a modular design allow customization, while maintenance-free bearings and self-lubricating slide bushes ensure low-maintenance operation.

Benefits

  • Prevents material bridging and segregation, ensuring consistent flow.
  • Supports a wide range of materials for versatile production capabilities.
  • Minimizes maintenance with durable, self-lubricating components.
  • Reduces operational interruptions due to its continuous and reliable feed rates.
  • Certified safe for dusty environments with ATEX Zone 22 compliance.
