Large silo for sale usually means the capacity of cement silo is equal to or more than 500t, which is more suitable for large construction project and water conservancy project. We all know high-capacity silos are close and they are used to store dry and small granular materials, such as, grains, cement and fly ash. In concrete batching plant, it works with screw conveyor and deliver the powder to each location. Generally, HZS25, HZS35 and HZS50 is equipped with 50t or 100t silo, and HZS60, HZS75, HZS90, HZS120, HZS180, HZS240 will use 100t, 200t and bigger silos etc. But if your construction site is remote, and it is much more difficult to transport concrete, it is better for you to choose a big silo. In a word, you can choose a prpoper concrete silo for sale according to your practical demands. While what you need to pay attention is that, welded type silo is usually equal to or less than 50t, bolted type cement silo is usually equal to or more than 50t. Such as, if you need a 100t silo, it must be bolted type. And this cement silo is shipped in container, and these parts will be connected by the bolts at the destination. We can also supply you large grain silos, which are also very durable and wear resistant. We can offer you 500t, 600t, 800t, 1000t, 1500t and 2000t large storage silos.
Installation of large silo for sale in New Zealand
Take 500t large cement silo for an example, it is a kind of closed cylindrical cement tank.
There is electrical dust-catcher device on the top of silo, it can adsorb some dangling particle, which can effectively prevent the materials from overflowing, reduce the pollution to surrounding environment and ensure the health of operator.
2. Arch breaker
At the bottom of large silos is equipped with arch breaker. It compress the air by adopting reverse control of small electromagnetic in gas control box, and release it to cement and materials to break arch. This design can avoid the jam caused by material accumulation in silo body.
3. Material level monitoring system
Level indicator can know the actual height of the materials in large scale silos and it can monitor the materials of large storage silos.
Components of Large Silo For Sale
1. Dust-catcher; 2. guardrail; 3. ladder; 4. body of bin; 5. level indicator; 6. feeding tube; 7. broken arch; 8. manual butterfly valve; 9. maintenance platform; 10. holder.
Dust-catcher: When the bulk cement pump truck deliver the powder to the silo, there will be draught head in and out of cement silo, the gas will be discharged from inside to outside, for large diameter silo is filled with powder, it is easy to generate dust and pollute the air. Thus, dust-catcher is to filter the gas discharged from silo, meanwhile, to make air pressure inside and outside achieve a balance. As the filter system, it is easy to gather dust, regular check is a necessity.
Guardrail: It is primarily protective. When the large silos for sale needs to be maintained, operator needs to climb to the top from the external ladder, enter the silo from the access hole on the top. Maintnance and clean of dust-catcher also need to be carried out on the top. Here is a tip for you to tell the welded type silo and bolted type silo. For welded type, guardrail is within the large steel silos, and it is external ladder. For bolted type, there is no guardrail and it it internal ladder. In addition, guardrail is welded by the circular tube.
Level indicator is to measure the height of powder material of the warehouse. We usually use rotary resistance level meter.
Its basic principle is whether there is material at the contact range in the large capacity silos and control the signal lamp to reach the alarm function. One silo can be equipped with one or two level indicator.
On the top: Measure the height of materials.
At the bottom: Measure whether there is material in silo, prevent the empty silo.
Broken arch: When the materials are discharged from the large silo for sale, for bigger silo body and smaller exit, it is easy to be blocked, materials can’t be discharged smoothly, while broken arch is to loose the materials and keep smooth operation. In general, 50t cement silo for sale is with 3 broken arch, 100t and more than 100t is with 6 broken arch.
Manual butterfly valve is the connection of large central cone cement silos and screw conveyor. During the normal operation, manual butterfly valve is open, the powder enters screw conveyor from the silo; when needs to check screw conveyor, it is necessary to close it.
Holder is located at the bottom of silo, it is attached to the ground. The height of the holder is changeable, it can be redesigned according to the different requirements. The bottom of the holder is connected with the foundation.
Application of big silos
There are two types silos, the difference is the shape of the discharge hole of the bottom. If the hole of the bottom is quadrate, this silo is used for stabilized soil mixing station, and connected with quadrate hole of the screw conveyor, the hole is little bigger.
While if the hole of the bottom is smaller and it is round, it will connect with round hole of screw conveyor. This type is usually used for concrete batching plant.
Routine maintenance for large capacity silos
1. Filter system: check whether the cloth in dust-catcher needs to be change, if it is under the control of pressure difference, just watch the differential pressure gauge.
2. Check dust cleaning system: there are mechanical dust cleaning mechanism and pulse clearing mechanism.
3. Power system: check whether the draught fan can work normally.
4. Check the leakproofness of the equipment.

Requirements need to concern when install the large storage capacity cement silos
1. Strengthen the education of quality, reinforce the quality awareness of operator, it is strictly prohibited for unlicensed personnel to apply for welding.
2. Before welding, it is necessary to draw a paper for large cement silos, operator should carry out according to the paper, scheme and welding process.
3. Ensure the safe welding process.
4. Avoid using welding materials without product qualification certificate and material certificate.
5. After the completion of the silo, fill the silo with water, after 2 to 3 hours, tap the both sides of weld with the hammer, if there is a leak, it is necessary to reweld and recheck.
Advantages of large diameter silos
1. Attractive appearance and compact structure.
2. Easy installation and convenient transportation.
3. Advanced welding technology and good seal performance.
4. Reasonable price and long service life.
