Klausen Process Machinery pneumatic conveying systems provide enclosed, dust-free transfer of dry bulk materials, with vacuum and positive-pressure options and stainless steel, food-grade builds.

Key features

Enclosed pipelines use air to transfer dry bulk materials, containing dust, reducing operator exposure and keeping contaminants out of the product.
Stainless steel, food-grade builds with easy-clean receivers and filters, smooth-bore pipework and quick-release fittings.
Compact footprint compared with belt conveyors, bucket elevators and screw conveyors. Pipework can rise vertically, run across ceilings and route around existing equipment; systems can be retrofitted into existing buildings.
No chains, belts or buckets along the route; maintenance is concentrated at the blower and receiver.
Level probes, load cells and timers support unattended operation within a fully controlled line.
Diverter valves and multiple receivers allow one line to feed several mixers, hoppers or packing machines in sequence.

Conveying options

Vacuum: pulls material towards the receiver; suits shorter runs, multiple pick-up points and mixer feeding, keeping leaks inward rather than into the room.
Positive pressure: pushes material from one source to one or more destinations; suits longer distances and higher throughputs.
Dilute phase: suspends powder in a high-velocity airstream; simple, economical and easy to install for free-flowing, non-abrasive powders including flour, sugar, starches and many plastics.
Dense phase: moves slow-moving slugs or plugs at lower velocity; gentler on fragile, abrasive, friable or blended products, reducing segregation, degradation and pipe wear.
Dense phase or carefully designed dilute phase systems protect friable granules and blends through controlled velocities.

Conveying distances

Specification	Value
How far can powder be vacuum conveyed?	Commonly up to around 30–50 m depending on the material; longer runs usually suit pressure systems.
How far can powder be moved with pneumatic conveying?	Distances from a few metres to well over a hundred metres are common.

Components and operation

Air mover options include a positive displacement blower, side channel blower, compressor or vacuum pump. Rotary valves, venturis or pressure vessels feed material into the airstream at a controlled rate.
Material travels through pipework and long-radius bends to a receiver, cyclone or filter receiver for separation from conveying air.
In the described vacuum cycle, a rotary vane vacuum pump creates negative pressure in the closed receiver and pipeline, drawing material through a suction wand. The filter separates dust and small articles, protecting the pump.
When the receiver fills, the pump stops and the receiver valve opens to discharge material. Compressed air from the air reservoir cleans the filter. After emptying, the valve closes and the pump restarts.
Suction and emptying times are generally PLC-set; level sensors or other control signals can control conveying time. Controls and safety interlocks sequence starting, stopping and cleaning.

System sizing and configuration

Conveying rates are sized to material, distance and required throughput. Design inputs include bulk density, particle size, moisture, temperature, abrasiveness, packing or bridging behaviour, horizontal and vertical distances, bends, elevation changes, and pick-up and discharge points.
These properties determine air velocity, pipe size and feeder type. Fragile products may require lower velocities; sticky or hygroscopic powders may require dried or conditioned air.
Combustible powders require consideration of ignition sources, earthing and explosion protection, including review of AS/NZS 4745 Code of practice for handling combustible dusts.

Applications

Transfers flour, sugar, milk powder, starch, resins and chemicals from bags, bulk bags, silos or drums to mixers, hoppers and packing lines.
Applications include silo filling from bulk bags, loading loss-in-weight feeders and transferring finished blends to powder filling machines in food, chemical, pharmaceutical, plastics and minerals processing.
Can form part of blending systems with bag stations, bulk bag dischargers and lump breakers.
