Dry-Bulk-Storage-Silos

Dry Bulk Storage Silos

PROTEM in cooperation with the Italian manufacturer SCUTTI designs and delivers ready-to-use storage solutions for cement and many other dry bulk materials.

There are different types of silo available, with a capacity ranging from 20m3 to 2.500m3. Mainly used are the paneled silos which are assembled with screws on site while telescopic and monolithic silos are also available.

Depending on their type of construction, they are suitable either for road transportation by lorries or shipping in containers. Galvanized finish is available on demand.

PROTEM can also offer solutions for big storage of dry powders, the so-called Terminals.

Pressure-relief-valves-for-silos

Pressure relief valves for silos

A pressure relief valve, also known as a safety valve, is a mechanical device installed on the roof of a silo and is designed to release or inject air. When the internal pressure reaches certain levels during filling or unloading, the safety valve activates by balancing the pressure.

This way the silo remains intact regarding the pressure changes that occur internally, as the safety valve is always ready to add or remove air in case the internal pressure goes past the predetermined limits.

A pressure relief valve is made of steel and is ideal for use on cement silo in the ready-mix concrete industry, but can also be used in any other application that includes bulk material storage.

Level-Indicators

Level Indicators

FOR CEMENT SILO AND AGGREGATE BUNKERS

The Bin Level Indicators have been designed to electrically signal for the minimum or maximum material levels inside the bins, hoppers or silos through rotating movement. It is the most economical solution for the supervision of one or more level points.

Fluidization-Pads

Fluidization Pads

To aid the flow of materials

The Fluidization pads for powders are used in concrete batching plants as a preventive measure. A variety of materials will show perfect mass flow as soon as certain amount of air is added at regular intervals during discharging of the bin or silo. The air enriched material gains desired flowability. At the same time, possible tendencies of the product to bridge, rat-hole, go lumpy or deposit are prevented.

They are mounted on storage silos or weigh or feed hoppers, as well as fluidizers for dry bulk trailers. Their installation is very easy both in existing and in new silos.

SMARTBOB2

SMARTBOB2

A POWERFUL INNOVATION IN SILO INVENTORY MEASUREMENT

The SmartBob2 is the most affordable and reliable solution for measuring the amount and weight of your silo contents. It is suitable for measuring solids, powders, liquids or sediments with great accuracy, without being affected by dust, moisture, material and environmental temperature.

Its installation is way easier in comparison to all other level measurement systems or methods and calibrating the system is not needed. SmartBob2 can be installed at the top of any type of silo, tank or container up to 55m in height, independently of its width.

3DLevelScanner

3DLevelScanner

ACCURATE VOLUME MEASUREMENT FOR POWDERS & BULK SOLIDS

3DLevelScanner is the only level sensor that measures multiple points on the surface of the material, as opposed to the usual single point measurement systems. This is achieved by using non-contact, dust-penetrating technology to measure stock volume and map the abnormal topography on the surface of the material. This advanced patented acoustics-based technology is proven to perform in powders and bulk solids contained in tanks, silos, warehouses, and even open bins and piles.

The unique 3D mapping capabilities of the system provide the visual representation of bin contents, using advanced low-frequency technology that penetrates the dust. This acoustics-based technology allows it to perform reliably even in suspended dust environments, such as gypsum, lime and filler, where other technologies have failed.

Weighing-Indication-of-Silo-Content

Weighing Indication of Silo Content

ECONOMICAL SOLUTION OF MEASURING THE CONTENT INSIDE THE SILO

Using the weighing system SiloRe@der you receive much more information than a simple indication for full or empty or a percentage indication based on a level measurement. On the contrary, SiloRe@der uses load cell technology sensors bolted to the silo legs without needing to lift the silo or make any changes on the silo legs.

Silo-Weighing

Silo Weighing

WHEN A GREAT MEASUREMENT ACCURACY IS REQUIRED

If you seek the greatest weighing accuracy for your silo, the most appropriate solution is placing the silo on top of weighing modules with load cells. PROTEM designs and manufactures special bases for cement silo.

The most complex part of the entire implementation is the base upon which the cement silo is placed. These bases must be designed in such a way, to provide the maximum security against earthquakes and strong winds, without reducing the weighing accuracy.

Protem's cement silo weighing bases has been designed especially for the territory of Greece that is influenced very often by strong earthquakes.
