Introduction of lipp steel silo

Steel silos are storage tools that are welded, riveted, or combined with steel plate. Steel silos are mainly used to store cement, fly ash, chemical powder, slag, grain, industrial powder and other granular material. According to their different construction methods, stain steel silos are divided into welded steel silos, assembled steel silo and lipp spiral folded silo.
Flyer is a spiral steel silo manufacturer in steel silo industry, and we can provide our customer lipp silo service from design to silo on site construction.
In this passage, we will introduce you construction process and advantages of spiral steel silo.

Material of lipp steel storage silo

To ensure the long service life and high quality of lipp steel silo, Flyer adopts high intense galvanized steel as silo construction material.
The silo body is composed by galvanized steel plate, the galvanized steel plates are offered by Han Steel Group which is one of the largest steel material manufacturers and suppliers in China. The plate has the characteristic of anti corrosion, high strength, good looking, low cost and so on.

Our galvanized steel plate takes the electrostatic painting technology, the galvanized layer is much more joint with the steel plate, and a more important way, the layer can prevent the steel plate away corrosion. The zinc coat is thick and compact, and the amount of zinc can reach 600g/m2, the more the zinc each squire meters contains, the anti corrosion ability will be better.
Different silos adopts different thickness of steel plate.
For different diameters of steel silos, designer will choose the proper thickness of steel plate. The thickness of steel plate ranges from 2mm to 6mm.

Equipment of building lipp steel storage silo

• Steel roller decoiling machine

This machine is used to decoil the galvanized steel plate coils, this is the first step of silo building, so that the steel plate can access to the bending machine.

• Steel plate bending machine

This machine can bend the steel plate with certain radian required by the diameter of the target storage silo.

• Silo forming machine

The silo forming machine machine is the most important equipment in silo building, steel plate after going through this machine will be folded together and the body of silo is formed.

• Silo supporting bears

Supporting bears is help to support the silo body, ensure the silo body can keep rising till the prospect height.

Double seam system

Double seam system is a unique feature of lipp steel silo. In the construction of silo installation process, the edge of galvanized steel plate are folded twice by our silo bending and forming machine. In this way, even the most aggressive material inside the silo can not find any leak to attack, the anti corrosion ability is beyond comparable.

The silo’s maximum safety can be achieved by using the Double-Seam system. The unique structure of the Double-Seam not only guarantees the storage tank’s leak-tightness, but also makes sure the silo can possess great stability, even the largest silos can resist huge horizontal pressure.

Advantages of lipp steel storage silo

1. Good overall performance, long service life. The anti corrosion galvanized steel plate and our professional can guarantee the quality and service life of these steel silos.
2. Well air tightness performance, wild application. The silo is well sealed with our any leakage, the silo bites together with out gaps, so for grain storage, they can meet the requirement of insecticide and fumigation.
3. Short construction period and low investment. Some of the parts can be prepared ready in the factory, as for on site installation, it doesn’t takes a lot of time and labor.
4. Covers a small area, easy to manage. The space between two silos can be narrowed to 500mm.

Working Theory of Screw Expeller Pressing

Screw expeller pressing is to separate the oil from oil bearing materials by the pressing power which comes from the change of chamber volume, drive from screw worm, resistance of curve teeth at press rings and extrusion friction between oil materials. Under the big pressure created in press chamber, the oil can be discharged from gap of press bars and oil trough of press rings. Either big scale and small scale of screw oil expeller, they have similar theories in screw expeller pressing. Because the screw type seed oil expeller is mainly used by extrusion theory, so it is also called as oil extruder or oil extrusion process..

A guidance of how to choose a steel storage silo

Excellent technology and management

Each steel silo project must be equipped with the construction personnel as following: project manager, project engineer, engineering technician, engineering information officer, front-line management personnel, front line operators and so on. In the construction of steel silos, strictly accordant with the requirements of the specification, follow the highest standards for technical disclosure, pay close attention to process management. Flyer is a steel silo supplier with years of experience and an experienced construction team. With a strong back up of a technology team and strong company strength.Flyer steel silo company is responsible to every front line staff and is responsible to every client of ours. In the construction of the steel silo and supporting frame, the safety consciousness of the employees is upheld, life is loved, and safety is concerned. Safety is the source of happiness, safety is the guarantee of effectiveness. The quality of steel silo is as heavy as the mountain to motivate employees and urge them to pay attention to safety. Careful design is the soul of engineering quality. Standard construction is the foundation of project quality. Strict supervision is the key to project quality. Government supervision is the guarantee of project quality. The steel silo is highly constructive, requires a simple foundation, and is quick to construct, independent of weather conditions. After understanding the superior performance of the steel silo, users should pay attention to the following issues during construction.

The choice of steel silo materials

steel silo usually choose the ordinary type of steel, with Q235 as the best, easy to draw, and low cost. If the silo wall thickness of the silo is calculated to exceed the capacity of the equipment, low alloy steel is used instead of Q235. Silo silo panels are usually galvanized to meet corrosion protection requirements. Therefore, the galvanized layer has become an important indicator for the construction of the silo. It directly affects the service life of the silo. China's standards are in line with foreign standards and require a galvanizing amount of 400 g/m2. All our steel plates meet the standard and have a better quality.

Choice of silo form

Second, the choice of silo form: The popular thin-walled silo is advantageous for both the squat silo and lipp silo. They have their own characteristics due to their different structural forms.
Our company mainly provide the construction of Lipp silo.

Features of Lipp silo

• Using hot galvanized coil continuous undercut forming, the color is uniform;
• High airtight. It can store water, oil and other liquid materials;
• Due to the silo wall is smooth, the required thickness is larger than the assembly silo.

Features of assembly silo

• It can be used hot-dip galvanized coil, flat, can also use electro-galvanized sheet.
• All parts are standard components and replaceable. Users in the course of use, such as damage or corrosion, you can easily replace the damaged parts to extend the service life.
• It can be modified, demolition, especially for users of rental space is very suitable.
• It can achieve the form of external columns, the flow of food in the silo is more favorable.
• Air tightness is worse than lipp silo, but after the use of silicone sealant, airtight requirements can be achieved.
• Double-layer insulation structure can be conveniently realized with little increase in cost.

The basic form of steel silo selection

The basic form of steel silo with two kinds of flat bottom and hopper bottom.
Flat bottom silo: general large-diameter silo application, need to be equipped with sweeping machine or manual clearance, this type of construction is relatively easy, lower cost .
Hopper bottom: Taking into account the self-flow of grains, the hopper bottom form is used in large numbers, and the hopper bottom is divided into three types: steel cone, semi-steel cone and cement cone. From the use of speaking, the three are not much different. , but there is a way to use backfill. Filling a conical bucket in the silo, although this method reduces the difficulty in the construction process, it wastes the material and capacity of the steel silo and increases the amount of civil engineering work.

How to build a steel silo?

About Flyer Lipp silo

Lipp steel silo is also called Spiral steel silo. As a storage tool, the main role of the steel silo is to storage grain, fly ash, slag powder, cement, chemical and so on.
Lipp steel silo double seam technology is a patented technology of the German technical engineer called Xavef Lipp. It applies the principle of metal plastic working hardening and thin shell structure. Use special technology and equipment to apply 2 to 4 mm thick galvanized steel (or stainless steel). According to the “spiral, double-seam and cleanching" process to create a Lipp steel storage silo with a volume of 100 to 5000 m3.
Lipp steel silo, also known as spiral steel silo, as the name implies, the whole silo body is spiraled and concatenated by using professional equipment. The Lipp technical silo has a short construction period, a relatively low cost, and a good quality. It occupies a small area, has no scaffolding on the floor to install the silo top, and is easy to construct. In recent years, due to the superior performance and other advantages of Lipp silo, the steel silos have quickly occupied the silo market. Steel silos now are wildly used in grain storage and other industrial powder storage.

Preparation of steel storage silo

Customized design

Once the order is settled. Generally, customers need to provide their design drawing of the steel silo. We can also provide free design for customers.

Semi-finished steel parts

Because of filed limited, some welded parts will be pre-manufactured and packed in our factory before delivery to best save cost on construction site and shorten construction duration. These may include all accessory parts, steel plate and other parts. Our steel plate and all accessories are all made of galvanized steel sheet.

On site construction procedure of Flyer steel storage silo

There are seven steps for on site construction procedure. The core of the construction is by using our spiral folding technology, it is also a symbol of Lipp silo unique technology which is different from other type of steel storage silo.

The main equipment that used in the construction process are decoiling machine, forming machine, bending machine and supporting bears. The use of these equipment will be introduced elaborately in the following steps.

steel silo on site construction

Equipment location

The first thing to do is locate all the necessary equipment on the decided on site location. There should be prepared concrete base or steel frame base. The selection of base is depend on different elements. P.S. The base construction does not contained in our bossiness scope. The diameter of the base is according to the size of the steel storage silo. When all the equipment are settled in the correct place, the construction of steel storage silo process can be started.

Silo bending

First of all, Use the decoiling machine to decoil the galvanized steel strip coils. During the construction process, the decoiled steel strip will be delivered to the forming machine. The forming machine will bend the steel strips to a certain radian according to the request of the target steel storage silo. With the help of silo forming machine, the bended steel strips after the bending machine can be seamed together to the double-seam system.
When the steel galvanized steel strip coils formed into double system, we need to use supporting bears to support the whole construction of the silo and make sure with the help of bearing support, the whole structure can keep rising.

Silo roof installation

Accompanying with the rising of the whole body, when the main body of the silo raises to a certain height, normally 2 meters high. Our workers will start to install the roof of the silo. Because the height of silo is range from 6 meters to 25meters, which is too high that the safety of workers can not be guaranteed. After the installation of the roof, the forming and bending will continue and the silo will keep raising.

Stiffeners fixing

With the raising of the silo, our worker will start to weld the steel stiffeners. Steel stiffeners are used to help the structure of the silo more stable and makes the silo lasting long and hard to collapse. We also use double stiffener plates to ensure the stability of stiffeners.

Silo lifting

For some small diameters steel storage silos or silos built on the ground. We usually use a crane to lift the whole body to load the steel silo on the basement. The main part of the silo has been complete.

Auxiliary equipment installation

After finished the silo body construction. Customers will always order some auxiliary equipment fixed on the silo that used to maintain and check the condition of the silo. There are some necessary auxiliary equipment, such as roof air vent, used to keep the air flowing, the ladder system, build by the side of the silo, and other auxiliary to make up the whole silo system.

We undertake turn key project from equipment location to auxiliary equipment installation, this does not only because we can ensure the quality of whole parts but also you can get the most cost effective offer.
If you get any question, you can send us e-mail, we are wiling to answer your questions.
