Why choose welded steel plate silos for cement storage

December 23, 2024

Introduction to cement

Cement is a powdered water-hardening inorganic cementitious material. After mixing with water to form a slurry, it can harden in air or in water, and can firmly cement sand, stone and other materials together. Concrete made of gravel cemented with it not only has high strength after hardening, but also resists erosion by fresh water or salt water. Mortar or concrete made of cement is widely used in civil engineering and construction, transport, water conservancy, electric power, petroleum, chemical engineering and construction, for the construction industry, especially the development of steel mixed construction of basic materials, known as the construction industry food. Many enterprises will use a large amount of cement in the production process. Therefore, how to safely and properly store cement has become a concern for many owners.

Precautions when storing cement

Cement is an active substance, easy to absorb moisture and carbon dioxide in the air, which will reduce the quality, so it should be kept well and should not be stored for a long time.

1. When cement is stored in the warehouse, attention should be paid to moisture-proof and rainwater leakage; it should be stacked at one time according to the arrival date of cement and stored first; the storage time of cement should not be too long, so as not to affect the strength of cement affected by moisture for a long time.

2. When storing bagged cement, the floor mat should be 30cm away from the ground and 30cm away from the wall; the bagged cement should not be stacked too high, so as to avoid the lower part of the cement from being compressed and lumped;

3. In order to ensure the strength and characteristics of cement, the long-term storage of bulk cement should be stored in moisture-proof, leak-proof Steel Plate Silo, in which welded steel plate silo is a good choice.

Customizable silos for cement storage and transportation

Reasons for choosing welded steel plate silo to store cement

Cement is easy to absorb moisture and carbon dioxide in the air, thus reducing its quality, while the welded steel plate silo has good airtightness, which can effectively isolate the air so that the cement is in a sealed state, ensuring that the characteristics of the cement will not change. Therefore, welded steel plate silo is the most common and ideal choice for storing cement materials. Welded steel silos are assembled and welded at the point of installation. All steels or alloys with welding properties can be used in the construction of the silos, and the welded Steel Silo walls can be made of several layers of different materials to meet special storage requirements. Most welded steel plate silos are large in volume and are built on a foundation base (not overhead foundations), coupled with its high-strength structure, these characteristics make the welded silo have a good tolerance for foundation settlement and seismic activity....

1, warehouse storage capacity: warehouse body diameter of up to 80 metres, a single warehouse capacity of 5000-120,000 tonnes, with special needs can also be increased;

2、Low initial investment: adopting a number of patented technologies of Dazheng, it can save about 50% of construction materials and more than 60% of land;

3, good storage effect: due to the welded steel plate warehouse sealing performance, stored cement, fly ash, sand, gravel, aggregates, etc. in a tight air isolation, the material is in a vacuum sealing state, to ensure that the characteristics of the material does not change.

4、Low carbon and environmental protection: the top of the silo is a load-bearing dome, and a pulse vibration dust collector is set at the top of each silo, which mainly collects the dust generated when the materials are put into storage, so that the concentration of the dust emission reaches 30mg/m or less.

5, short construction period, long service life: according to different geological conditions, site environment and capacity, usually the construction cycle is different, while the general construction cycle of the welded steel plate warehouse is about 4 months, and its service life can be up to 30-50 years.

6、Advanced discharging: the large steel plate warehouse accumulates the advantages of other steel plate warehouses, and designs a new pneumatic discharging system by itself, relying on pneumatic pressure to transport the materials in the warehouse to the designated location. 1-50,000 tonnes of design of a discharging port, and 50,000 tonnes of design of more than 4 discharging ports. Adopting frequency conversion technology, the storage capacity can reach about 500T/H.

7、Convenient storage: according to different materials and factory conditions, the materials can be stored by elevator, inclined chute or pneumatic pipeline.

8, flexible process layout: according to the actual situation of the site, using a variety of forms of arrangement, the direction of the discharge corridor, the choice of lifting equipment can be determined according to the actual situation of the site. The layout of welded steel plate warehouse is free and flexible, which can meet the various needs of customers.

Homogenizing and conveying of raw materials in rolled steel plate silos

Design optimisation of cement steel plate silo:

Avoiding discharging difficulties: well-designed foundation waterproof structure, strict foundation treatment requirements, pneumatic conveying and air pressure balancing of air after strict drying, the air tightness of the silo wall should be strictly controlled. And try to make the bottom of the discharge gallery above the water table. Design the sealing valve in case of failure of the lower material outlet which is difficult to discharge the material, in order to realise the maintenance and replacement of the lower material outlet. And design the spare emergency discharge through material for clearing the warehouse and dealing with the failure of discharge difficulty such as accidental slating.

Avoid tilting of the silo: give priority to rigid foundation and rigid foundation to ensure even stacking of incoming materials, and give priority to single-point discharging method. No matter what kind of discharging method, should give priority to the use of gravity self-flow based discharging method, in order to reduce the use of energy consumption and maintenance costs, while the pneumatic fluidisation of discharging as a supplement; silo design should leave enough margin, and consider the material skewed under the limit of the silo's stability and strength requirements. Silo body should be subject to a certain amount of micro-negative pressure, wind load, the internal material skewed storage of these four loads together to design, only this is guaranteed.
