how does a cement silo work?

A cement silo is a type of vertical tank that is used to store various bulk materials, for example, fly ash, grain, and cement. The vertical tank is fitted with a clear material level system, which shows the position of the contents.

In a concrete batching plant, cement silos are used to store fly ash, cement and other bulk materials required for concrete manufacturing. So, how does a cement silo work? Well, lets outline some of the working principles.

When it comes to installation, a truck crane is used to lift the cement silo up and place it onto prefabricated concrete foundations. Next, installers must ensure that the silo is vertical before welding the unit firmly into place using the embedded steel structures in the foundation.

Once the empty silo is fixed into place, a bulk cement truck arrives on-site and a conveying pipeline is attached to the outlet of the cement truck and the feeding pipe of the silo. A gas pressure pump is then used to convey the cement from the truck into the silo.

To discharge cement from the silo, the manual discharge value located at the base of the core must be opened. The cement will then flows through the screw conveyor. If arching occurs during discharging, the electromagnetic valve button is pressed to blow air into the system to eliminate arching and allow for smooth cement delivery.

The working operations of a cement silo are very simple. You basically just have a large vertical tank with a cone base featuring a manually operated valve. The cement flows from the silo due to the force of gravity, so no pumps are required for discharging.

As the installation of cement silos requires concrete foundations, steel pipes, and welding processes, its important to buy high-quality units. You dont want to risk installing a poor-quality silo that requires replacement soon after installation. The good news is that there are loads of manufacturers of high-grade cement storage silos in the marketplace, you just need to know how to choose the best suppliers.

If you are planning on purchasing a concrete batching plant, many suppliers will include some silos as part of the design. However, you might prefer to purchase additional silos from a different supplier to extend your plant operations.

When looking for cement silos for sale, be sure to check out all the technical specifications of cement silo and not just the price tag. You need a unit that has adequate capacity for your material storage needs.

Cement storage silos are on-site storage containers that used for the storage and distribution of various types of cement mixtures. Spiral steel silos for cement storage come in a variety of sizes, which makes them ideal for both large-scale and small-scale cement plants. According to different actual needs, cement storage silo can be designed to be a permanent structure, or a portable model. Like many other types of steel silos, the cement storage silos are usually equipped with blowers to expel the cement into a truck or other containers.

The height and volume of cement storage silo vary according to different storage requirements. In real world application, the cement storage silo can be structured to hold no more than a few tons of dry cement production, or be designed to efficiently hold several hundred tons. Generally speaking, cement storage silos with big size are cannot be moved because of permanent structures. Cement silos with permanent structure are likely to be found at concrete plants, where the finished product is stored until it is time for shipment. Many building sites that utilize concrete in the construction process opt for portable cement silos that can be moved around the site as the need arises. It is very common for construction companies to keep several portable cement silos available for different building projects. These simple storage devices can usually be set up in a matter of hours, then dismantled once the project is complete. The storage principle of the portable cement silo is quite easy, since the components can be stored in a warehouse until the device is needed at another building site. As a necessary equipment of cement storage silos, blowers are necessary for both the permanent and the portable cement silo. The blower makes it easier to expel the product from the silo. Blowers are often driven by electricity, although there are models that rely on propane or even gasoline. Blower equipment with the portable silos takes very little time to set up, and can also be stored easily when not in use.

The plane and vertical layout should according to construction technology, terrain condition, engineering geology, execution conditions and so on. After accounting price and considering technological level, the best plan for cement silos would be determined.

In a cement silo group, single and multiple rows are the most common plane layout. The distance of two silos needs to be more than 400mm. When applying independent foundation, foundation designs are available. For floor flat cement silo, the distance of cleaning equipments should be considered.

The conveying equipments and maintenance platform of building above top of silo should apply open steel channel structure. For special technical requirements, enclosed corridor is also available. The roof of steel silo should be designed conical shell with top and under tube, or truncated cone space truss structure. The steel cement storage silos are thread designed and applied galvanized steel sheet, its the most popular technical process for steel silos in todays silo construction. The bottom of steel cement silo can apply concrete structure or steel structure to support the silo body. For cement silo with a diameter below 10 meters, its better to apply column supporting structure, wall supporting structure or cone bottom structure. For cement silo with a diameter more than 12m, flat bottom silo is the optimum structure, and tunnel discharge channels are applied for the type of cement silo structure.

The design of spiral steel silo should according to the ultimate limit states and serviceability limit state. Cement storage silo designed with ultimate limit state should apply design value of a load and design value of material strength, calculated content to include:

50 ton cement silo: working principles

50 ton cement silo: working principles

Cement silos are essentially just vertical storage tanks used to hold some of the raw materials required for concrete manufacturing, such as cement powder, fly ash, and various aggregates. Fitted to most silos is a material level strip, that allow operators to see the volume of materials left in the unit at any given time. Now, lets discuss a few of the working principles of the 50 ton cement silo.

At the installation stage, a crane is required to position the 50 ton silo onto solid concrete foundations that have been prefabricated. Before the unit is welded in place, installers much check for perfect alignment. Once alignment is ensured, the unit is welded onto the steel poles protruding from the concrete foundations.

After the new silo has been installed, a truck delivering cement powder is ordered to the site. A conveying pipeline outlet is securely attached to the cement trucks outlet before a gas pressure pumps convey the powder from the truck to the cement silo.

While the conveying pumps are in operation, manual workers frequently activate the dust collectors vibration motor to prevent powder from attaching to the filtering bag, which could result in blasting or a blockage.

When it comes to discharging cement powder from the vertical storage tank (silo), the manual value, stationed at the base of the unit is opened. Once opened, the powder flows through, aided by a screw conveyor. As arching presents, operators can activate the electromagnetic valve button. Doing so results in a shot of air entering the system to distribute arching and ensure the continuous discharge of the material.

The working principles surrounding a cement silo are certainly fairly basic. The large vertical storage tanks only moving part is the discharge valve at the cone base. No pumps are needed for discharge as gravity ensures the contents of the silo empty without power.

Give the fact that 50 ton cement silos need solid concrete foundations and welding work for installation, its vital that high-quality silos are procured. The installation process can be expensive, so the last thing you want to do is install a silo of sub-par quality that requires repair or replacement within weeks. Fortunately, there are many high-grade silos on the market. The key is to research the best brand name manufacturers.

Those thinking about investing in a concrete batch plant need to ensure they pay special attention to the cement silos. Most concrete mixing plant suppliers include raw material storage silos as part of the configuration. Other suppliers, however, may require you to obtain silos from a separate source. You can also add new silos to your facility at any time to expand operations.
