How we selected these companies
ShowHide
We compared pneumatic conveying suppliers on five technical areas that decide whether a supplier fits a transfer duty.
- Pneumatic conveying range (25%) looks at the conveying modes a supplier builds, vacuum and pressure, dilute and dense phase, plug conveying, and at the rates, distances, and pressures those systems cover.
- Application coverage (25%) looks at the materials and duties the equipment is applied to, from pellets and food powders to cement, fly ash, and battery materials, and from truck unloading to blender loading.
- System integration (20%) covers how far the scope reaches beyond the conveying line into storage, feeding, dosing, weighing, dedusting, process equipment, and automation.
- Component design and certifications (15%) covers rotary valves, diverters, and receivers with their sizes, pressure and temperature ratings, wear protection, hygienic finish, and hazardous-area approvals.
- Testing and service (15%) covers test centers where your material can be conveyed before purchase, their line lengths and capacities, and support from startup through maintenance.
Range and application coverage carry the most weight because the first question for any powder and route is whether the supplier builds the conveying mode the duty needs, at the required rate and distance, and has applied it to a comparable material. Integration follows, because a conveying line only performs as well as its feeding, receiving, and control interfaces.

How to read this shortlist
Coperion, Hosokawa Solids Solutions, KREISEL Industries, VAC-U-MAX, and Hefei Teclion Machinery Technology supply pneumatic conveying equipment and systems, from complete dilute and dense phase plants to vacuum receivers and conveying valves. The order reflects conveying range, application coverage, system integration, component design and certifications, and testing and service.
The five differ in scope. Coperion and Hosokawa Solids Solutions build conveying into complete plants with feeding, dosing, and weighing. KREISEL Industries concentrates on long-distance conveying of abrasive mineral dusts and on wear-protected rotary valves. VAC-U-MAX centers on vacuum conveying, and Hefei Teclion Machinery Technology supplies rotary and diverter valves for dense and dilute phase lines. Decide first whether your project needs a system supplier or a component supplier.
Define the conveying question
Pneumatic conveying spans vacuum pickup, positive-pressure transfer, batch vessels, continuous feeding, and dilute or dense phase flow, often in combination. The right arrangement depends on material behavior, source and destination conditions, route, capacity, product quality, utilities, cleaning needs, and hazards. Qualify suppliers against these facts, not against one preferred label.
State the objective plainly. The plant may need to replace manual handling, cut dust, protect product, work around a layout constraint, raise capacity, or link several sources and destinations. Each objective shifts the value of flexibility, automation, containment, energy, and maintenance. A strong proposal explains the tradeoffs and names the requirement that controls the design.
Build a complete material and route data set
Material data: particle size, bulk density, permeability, cohesion, moisture, temperature, fragility, abrasiveness, electrostatic behavior, and relevant hazard information. Send representative samples when testing is planned. A familiar product name is not enough, because grade, supplier, storage, and process history all change conveying behavior.
Route data: horizontal distance, vertical lift, bends, flexible sections, source and destination pressures, available space, and future expansion. Define minimum and maximum rate, batch pattern, operating hours, changeover expectations, and the cost of a line stop. With this in hand, bidders can state their assumptions and you can compare designs on an equivalent basis.
Use videos to sharpen the inquiry
A good video shows equipment arrangement, operating sequence, access, and application context more clearly than a short product page, and it helps a buyer ask sharper questions. It still has boundaries: the filmed configuration may be old, may show one material, and may omit utilities, safeguards, control details, or problems met during operation.
A video shows one installation, not your duty. Ask the bidder for the current configuration of the proposed solution. When a point seen in a video affects selection, have the proposal confirm it with conditions, model details, and an acceptance method.
Compare system engineering rather than components
A pneumatic conveying package covers feeding, motive air, pipeline, bends, receiving equipment, filtration, controls, and interfaces. The proposal should say who owns each element and who guarantees the complete cycle. Component selection without system responsibility invites capacity disputes, unstable operation, overloaded filters, or a line that is hard to recover after a blockage.
Ask for an operating narrative covering startup, normal transfer, rate change, shutdown, line clearing, cleaning, and fault recovery, then review the instruments, alarms, permissives, and operator actions behind it. Availability lives in these details. A nominal rate says little about a system that needs frequent manual intervention or cannot restart reliably after routine disturbances.
Protect people, product, and plant
Combustible dust, hazardous-area suitability, pressure protection, food contact, and pharmaceutical compliance each need their own check against the offered configuration. Your engineering team must supply current requirements and verify the offered safeguards. Review dust containment, grounding, isolation, pressure relief, stored energy, hot surfaces, access, and maintenance for the complete connected system.
Product quality needs its own acceptance basis. If breakage, segregation, temperature rise, contamination, or residual product matters, define the sampling method and the allowable change. Cleaning claims should spell out access, sequence, waste handling, inspection, and verification. Pneumatic transfer reduces manual handling; it does not remove the need for disciplined hygiene and hazard review.
Evaluate commercial scope and support
Compare one installed-cost boundary that includes utilities, structures, electrical work, controls, installation, commissioning, training, spares, and performance testing, and record the exclusions. Compare energy at the same duty with the full motive-air system included. Compare maintenance across filters, valves, seals, bends, vacuum producers, blowers, and cleaning labor.
Support should turn into named commitments: who runs tests, who completes detailed design, who attends startup, and who responds when the system misses its guarantee. Ask for references with similar material behavior and route. A rank helps direct the inquiry, but the award belongs to the supplier that demonstrates the best fit for the project in testing and in the proposal.
For project use, keep a decision record of what the bidder committed to in writing and which claims were confirmed through testing. That record makes later review easier and keeps a figure from one model or duty from being carried over to another.

Frequently asked questions
Which pneumatic conveying supplier is best?
There is no universal best supplier. The right choice depends on the material, the conveying mode, the route, the transfer rate, and the process conditions. A plant moving fragile pellets needs a different system than one moving hot fly ash or loading a pharmaceutical blender, so compare bidders on trials with your own material.
Can a supplier pay for a higher position on this list?
No. The ranked positions follow the five technical criteria: conveying range, application coverage, system integration, component design and certifications, and testing and service. Booked and Featured places are labeled as such and carry no rank.
When does dense phase conveying make sense instead of dilute phase?
Dilute phase carries particles airborne at high gas velocity, typically 15 to 40 m/s, and suits free-flowing, insensitive, non-abrasive materials. Dense phase and plug conveying move product at low speed, down to about 0.5 m/s, under higher pressure. That protects fragile or blended products and cuts wear with abrasive ones, at the price of a more demanding feeder and control design.
What should buyers provide to a pneumatic conveying supplier?
Provide representative material data, the required minimum and maximum rate, route geometry with distances, lift, and bends, pickup and destination conditions, the duty cycle, and your hygiene, containment, and safety requirements. Send a representative sample if a conveying trial is planned.
Why run a conveying trial before ordering?
Conveying behavior depends on particle size, bulk density, fluidization, and cohesion, and it changes with grade and moisture. A trial on a test line of known length and diameter yields pressure loss, air demand, and product degradation data for your material, which the supplier can scale to the real route and write into the guarantee.
