Large Steel Silo for Cement Storage

Steel silo structural parameters and cement storage quality


1. Steel Silo Structural Parameters

The steel silo is a new concept of the load storage. The optimum height-to-diameter ratio of the steel silo is 1 : 1 or so. Steel silo is a significant invention for storage of bulk cement. It can not only solve the problem of safe storage of cement and fly ash in the off-season, but also has the problem of shortage of supply during peak sales season. It is also a repository for the centralized use of cement and bulk transfer and have a very prominent effect in energy-saving emission reduction and environmental protection .

2. Cement Storage

Inside the steel silo, the cement will be stacked continuously along the slope at the time of storage, so that the cement stored at different times can be evenly distributed.

In the discharging process, the gasification pipe in the bottom of the silo is alternately inflated in sequence so that the high-density sedimentary cement is vaporized and mixed in the gas infiltration until it forms a fluidized state. It passes through the discharge port of the silo and enters transport vehicle through the outbound transfer pipe.

The physical properties of cement before and after storage are basically the same. The initial settling time of the discharged cement was slightly longer and the flexural strength was slightly reduced. The compressive strength at 28 days increased by 0.17 MPa, indicating that the storage effect was ideal.

Production Requirements and Material Usage


The load on the steel silo is completely accumulated on the ground. Because the pressure caused by the accumulated cement is even, the reservoir floor does not require special treatment except for the discharge channel and the moisture barrier layer. The welding of the silo body in the steel silo is a lap joint and does not require support strengthening measures. In addition to shaped steel tubes, spherical domes do not require special reinforcements neither.

Total Investment


The total investment of the steel silo consists of the basic investment of the steel silo and the investment in the cost of the database. If the silo is built on the poor flow of sand, the basic investment of the steel silo will account for 34% of the total investment; if it is built in a soft and squishy place, the basic investment will not exceed 15% of the total investment. If it is built on sandy ground, the cost could be even lower. The total expenditure of different consumables and transportation charges for different reserves in different regions after entering the factory, plus 30% to 40% of tools, welding rods, antirust paint, and construction costs, can basically be regarded as the total investment in the cost of the steel silo.

Conclusion


1. The steel silo can guarantee cement storage quality.

2. Enterprises of different scales can use different reserves and quantities of steel silos to ensure continuous production, meet the sales requirements of peak seasons, and maximize corporate profits.

3. The low investment and the high speed in construction can solve the problem of cement storage during off-season in a relatively short period of time (sometimes silos could be finished constructing around a month).

4. Its diameter ratio is large, it does not tilt down, and is safer than small silos in the event of an earthquake.

5. It is suitable for a variety of geological conditions, and the pneumatic transport can make the cement away from the production workshop, making sales more convenient.

Structure Forms of Steel Silo Roof

图片
The silo roof is the structure that closes the top of the silo, Its shape is generally hemispherical or arched. The silo roof is one of the major auxiliary works for the steel silo construction. However, what is the specific structure of the silo roof? This article will give you the answer. Silo Roof Types There are three basic structural forms of the roof of the steel silo, which are the profiled steel frame roof, truss roof, and grid roof. The choice of the roof is mainly determined by the span of the steel silo and the equipment load at the top of the silo. Steel skeleton roof is generally used for steel silo whose span is less than 27 meters and its roof equipment load is less than 50KN, and there is no horizontal force. The truss roof is usually used when the silo span is 27 to 50 meters, the roof load is less than 200KN, and there is no horizontal force. And when the silo span exceeds 50 meters, the roof load exceeds 200KN, and there is a horizontal force and

Grain Silo Introduction

Grain Silo There are three types of storage facilities commonly used by grain companies: brick warehouses,  spiral steel silos  and reinforced concrete silos. Except for some small-scale factories that use brick warehouses, large and medium-sized factories both prefer the latter two types of storage facilities. Steel silos were first widely used in Europe and America. The  steel silo for grain storage  originated in the early 20th century. By the end of the 1970s, steel silos had virtually replaced any other type of granary. Especially in the United States, Canada, and other developed countries, steel silos have become the mainstream silo type of granaries. Because of its many advantages, such as less investment, short construction period, and small floor space, the steel silo have become the preferred warehouse type for grain storage and have broad market prospects. What are the advantages of using steel silos to store grain? At present, grain companies mostly choose thin-

The Advantages of Spiral Silo Compared to Traditional Storage Tanks

1. What Is Spiral Steel Silo Tank Technology? The spiral storage silo is also called lipp tank, it was invented and named by a Germen engineer in the 1970s. Through decades of development, it has already become the most advanced tank construction technology around the world. It uses a double seam system, this technology created a special way to build a storage tank. 2. What Are Traditional Tank Construction Technologies? The traditional storage tanks include concrete tank, welded tank and bolted tank. 1) The concrete tank is the oldest storage tank. The materials  used to build a concrete tank include steel bar, cement, sand, gravel and water. 2) Bolted tanks are steel made, with 6mm-10mm steel bolting, they can be very strong. 3) Welded storage tanks are also called welded steel tanks. they are made of welded steel plates whose thicknesses can range from 4mm to 10mm. 3. The Advantages of Spiral Storage Silo Compared to the traditional storage tanks, spiral storage sil
