Question 1

When should I choose dense phase instead of dilute phase?

Accepted Answer

Choose dense phase for abrasive or fragile products, long distances, limited compressed air, or when pipe wear and particle breakage must stay low. Dilute phase may still suit short, free-flowing, non-abrasive duties.

Question 2

What is a blow tank / dense-phase transmitter?

Accepted Answer

It is a pressure vessel that fills with product, seals, pressurizes with compressed air, then discharges a batch into the conveying pipe at high solids loading. PLC logic repeats fill, fluidize, convey and purge cycles.

Question 3

Gravity fill or vacuum-assisted fill - which do I need?

Accepted Answer

Gravity fill is common when product can drop freely into the tank from a silo or hopper. Vacuum-assisted fill helps fine or poorly flowing powders enter the vessel and can support higher rates or smaller pipe investment. We select after reviewing material and layout.

Question 4

How far can dense phase convey?

Accepted Answer

Short in-plant routes through to several hundred metres are common; optimized systems can exceed about 500-1500 m depending on material, pipe size and air supply. Final distance is confirmed by calculation and, when needed, material testing.

Question 5

What maintenance matters most?

Accepted Answer

Keep inlet and discharge valve seals in good condition, watch for wall build-up with sticky powders, and keep fluidizing nozzles clear. Pipeline bends and receiving filters should be inspected on a planned interval.

Question 6

What data do you need for a quotation?

Accepted Answer

Material name, bulk density, particle size, abrasiveness / fragility, temperature and moisture, required t/h, conveying distance and lift, number of sources and destinations, available air pressure, and preferred materials of construction.
