Pneumatic Conveying for Foundries:
Dense-, Lean- & Dilute-Phase
Move silica sand, reclaimed sand, binder powders and additives through sealed pipe, no belts, no bucket elevators, no fugitive dust. Axmann engineers complete pneumatische Förderung systems for 24/7 foundry operation, Made in Germany.
What is Pneumatic Conveying?
Sand and Powder Transport, Sealed From Pipe to Silo
Pneumatic conveying, or pneumatische Förderung, moves bulk solids through a sealed pipe using pressurised or vacuum air flow. In a foundry it replaces belts, bucket elevators and screw conveyors for nearly every sand and powder transfer, from silo to continuous sand mixer, from shakeout into sand reclamation, from reclamation back to storage, from binder drums to dosing stations. The pipe can route around columns, over machines and through narrow aisles, wherever open conveyors would never fit.
The advantages stack up: a fully sealed system with no fugitive dust, flexible routing that adapts to any building layout, minimal moving parts in the flow path (only rotary valves and blowers), the ability to combine transport with dedusting in one loop, and robust compatibility with every common foundry bulk material, virgin silica, reclaimed sand, zircon, chromite, bentonite, furan resin powder, catalyst and baghouse fines. Axmann designs the line as one integrated system: blower station, feed point, pipe run, receiving filter and discharge, sized to material, distance and duty cycle.
Conveying Phases
Four Conveying Modes, One Engineering Team
The right mode is selected per material and transport distance. Axmann sizes each loop for lowest energy per tonne without sacrificing reliability.
1
Dense-Phase Conveying
Sand moves in slugs at 3 to 8 m/s. Low velocity, high solid-to-air ratio, gentle on the grain, low wear on the pipe. The right choice for reclaimed sand and coated grains.
2
Lean-Phase (Medium) Conveying
The mid-range compromise, 10 to 18 m/s. Suitable for most virgin sand and additive transfers, balancing energy, capacity and pipe life.
3
Dilute-Phase Conveying
High velocity, 20 to 30 m/s, grains fully suspended in air. Lower capital cost, best for short runs and fine powders where pipe wear is not a major concern.
4
Vacuum Conveying
Negative-pressure loop pulls material from multiple feed points to a central receiver. Inherently dust-free at the loading end, ideal for shakeout pick-up and bag-breaker stations.

Why Pneumatic?
Six Reasons Foundries Choose Pneumatic Over Mechanical
Fully Enclosed, Zero Fugitive Dust
Sealed pipe from feed to discharge. No open belts throwing sand into the air, shop atmosphere stays well below silica exposure limits.
Flexible Routing
Pipe goes where belts cannot, over machines, around columns, through narrow aisles. Brown-field retrofits become possible that were previously blocked by layout.
Minimal Moving Parts
Blower and rotary valve are the only mechanical components in the flow. Less to maintain, less to break, longer intervals between service.
Material-Flexible
Silica sand, reclaimed sand, zircon, chromite, bentonite, furan powder, catalysts, all through the same engineering platform, configured per material.
Cleaner Workplace
No open sand on the floor. No cleaning crews chasing spillage. Lower cleaning cost, fewer slip hazards, better silica compliance.
Integrated Dedusting
Dedusting is built into the conveying loop, not an afterthought. Cyclones and baghouses capture fines at the receiving end before they can escape.

Pneumatic conveying is the nervous system that connects the rest of the line. These are the systems it feeds and is fed by.
