Energy saving possibilities for pneumatic conveying systems in the cement industry

Pneumatic conveying systems enable the transport of fine bulk materials in closed pipelines and thus often have lower investment costs compared to mechanical conveying systems, although many different feeding systems makes it difficult to choose the best and most economical conveying solution.

There are system suppliers who have different feeding systems in their portfolio. However, each supplier always has a preference for "their own" system. When working out the best and most economical pneumatic conveying solution, considering all the general conditions, independent advice can often be helpful.

You are planning to build a Cement Import Terminal?

Knowledge is the key to an optimal solution for you.

Do not just rely on the suggestions of suppliers. An independent look at your plans and ideas can not only save investment costs, but also prevent unnecessarily high operating costs. When selecting terminal solutions, choosing the cheapest alternative is often not the right solution unless operating parameters, performance, efficiency, and whole-life costs are considered; value for money should always be the goal.

Cement Import Terminals in bolted Steel Silo Design

Cement import terminals with bolted steel silos are being used more and more. The advantages are the high flexibility, a fast assembly, and the possibility to dismantle them if necessary and to rebuild them at another location. Innovative solutions in construction and assembly make this silo variant attractive for terminal operators. There is a clear trend towards larger silo volumes for bolted steel silos with conical outlet. If the limit was approx. 3,000 t storage capacity about 10 years ago, capacities of 7,000 t are already reached today. However, this tendency also holds dangers and reaches constructive limits, which in turn limit the flexibility of such plants. How are bolted silo plants constructed, what must be considered in the design and where are the dangers of such a silo plant?

This blog will help you to find answers to these questions.

Self-Discharging Cement Ships

Self-discharging cement ships allow independent operation because they do not require land-based ship unloading equipment. The closed systems of self-discharging cement ships offer significant advantages in the transport of cement, granulated blast furnace slag and fly ash:

Clean loading and unloading, as the emission of cement dust is avoided
No contamination or agglomeration of the load due to water ingress
Weather-independent loading and unloading through closed transport systems
Better planning and schedule reliability for delivery
Fully automatic equipment for high loading and unloading rates

As is often the case, the devil is in the details when it comes to choosing the right unloading system.

Pneumatic ship unloader vs. mechanical ship unloader

"We are planning the construction of a cement terminal and would like a comparison between a pneumatic and a mechanical screw unloader, which is the better unloading system?"

This question is put to me very often and my answer actually always starts with: "That depends..."

Aspects of throughput rates for continuous ship unloaders

The throughput of a ship unloader is still a much-discussed topic. The main reasons for this are the different views and definitions of manufacturers and terminal operators.

For the manufacturer of the ship unloader the throughput capacity is important for which he has to design the conveyor system. For a mechanical ship unloader, this is the peak throughput that the ship unloader achieves under optimal conditions and is important because the conveyor system behind the ship unloader must be able to handle this peak throughput.
