Informa Exhibitions Ltd regrets to announce the closure of Solids & Bulk Handling magazine.

Solids & Bulk Handling magazine has been affected by the ongoing downward trend of on-the-page marketing spend. This combined with the economic pressures that the loose and solids handling industry face has ultimately led to the sad and difficult decision to cease publishing the magazine.

The November/December 2017 issue of Solids & Bulk Handling will be its last edition.

Best Materials to Convey in Aero Mechanical Conveyors

How does an Aero Mechanical Conveyor work?

Aero Mechanical Conveyors (AMCs) are among the most efficient conveying solutions out there. They offer total batch transfer, relatively low power consumption and can deliver product across multiple planes. All of that can be accomplished inside a dust-free and hygienic closed system.

AMCs are considered reasonably gentle conveyors; Spiroflow recommends an 80% air to 20% material pocket fill to ensure the material is conveyed in an air stream and can gently navigate bends and corners within the conveyor. The way the AMC operates also prevents material degradation ensuring that blends are maintained throughout the transfer.

What should go inside an Aero Mechanical Conveyor?

It’s always best to utilise a test lab to ensure your product will run inside a conveyor to your rate and capacity requirements. Dry, moist, and cohesive material, as well as fine particules, will generally run effectively in an aero mechanical conveyor, however, we highly recommend that you ask your manufacturer to test out your material first.

What might work inside an Aero Mechanical Conveyor?

You can never underestimate the importance of testing, as it is hard to know if any specific material will or will not work well in an AMC. There may not be any issues with fragile or hygroscopic materials but you must run a test to be sure. A material test early on in the process will prevent headaches in the future.

What should stay out of an Aero Mechanical Conveyor?

Sludge-like or highly abrasive materials and slurries certainly need to stay away from AMCs. These materials will shorten the life of your AMC and extend downtime.

Don’t overdo it!

Using the correct material isn’t the only thing to pay attention to. It’s also vital for the life of your conveyor to pay attention to how much material is being conveyed at once. Over-feeding a conveyor is one of the main reasons for calls to our service department. It can put too much strain on the AMC if an operator tries to max out its capacity. A good supplier will make sure your conveyor is correctly sized to stave off the temptation of over-feeding an aero mechanical conveyor.

On the other hand, you shouldn’t run the conveyor while empty for too long. Running an empty AMC reduces the number of hours the conveyor or its components will last.

Other conveying options

If an aero mechanical conveyor isn’t the right choice to convey your material, there are plenty of other options. Based on your application requirements those alternative solutions might include ultra-heavy-duty structural drag chain conveyors, heavy-duty tubular drag chain conveyors, tubular cable drag conveyors, or flexible screw conveyors.

Test everything out

Regardless of the conveyor, material, or layout, we always recommend that a test is performed using your conveyor of choice at the manufacturer’s test lab. Spiroflow has test labs in the UK and US. Clearly it is much better to find a problem in the lab than on your shop floor.
