Storage Silo
Storage Silo is a key equipment in the pneumatic conveying system for storing and supplying dry bulk materials such as powders and granules. It not only provides a temporary material storage space, but also optimizes the fluidity and discharge efficiency of materials through its design, ensuring that materials can smoothly enter subsequent transportation or processing links. The design and selection of silos are crucial to maintaining the stable operation of the entire system
Principle
The working principle of the silo is based on its structural design and the operation of auxiliary devices:
Inlet and outlet: There is an inlet on the top of the silo, which is used to receive materials from the upstream process; there is an outlet on the bottom, which is connected to downstream conveying or processing equipment.
Conical or wedge-shaped bottom: In order to promote the flow of materials, the bottom of the silo is usually designed to be conical or wedge-shaped, so that the material can naturally slide towards the discharge port and reduce the possibility of blockage.
Vibrator or arch breaking device: Some silos are equipped with vibrators or arch breaking devices to prevent materials from forming bridges in the bin and ensure smooth flow of materials.
Air cannon or purging device: For materials that are easy to agglomerate or adhere, an air cannon or purging device may be installed inside the silo to regularly clean the residual material on the silo wall to maintain smooth material flow.
Weighing sensors: Some smart silos are equipped with weighing sensors that can monitor the weight of materials in the silo in real time and provide feedback information to the automated control system. When the material enters the silo, it gradually settles to the bottom of the silo due to gravity and is discharged through the discharge port. If the material has poor fluidity or is prone to agglomeration, the auxiliary device will be activated to ensure that the material can be discharged smoothly. Parameter

Features
The configuration of transmission lines and pipelines is flexible and not restricted by path conditions;
The sealed conveying pipeline is not affected by the climate and surrounding conditions, and prevents the material from getting damp, stained, and mixed with foreign matter;
There is no flying dust during the transportation process, making it easy to meet environmental protection requirements;
During the transportation process, multiple process operations can be realized at the same time, such as mixing, crushing, grading, drying, cooling, dust removal, etc.;
Can carry out long-distance centralized and dispersed transportation;
The equipment is simple and easy to operate and maintain;
Project investment and maintenance costs are low;
It is easy to realize automation, requires few workers, and has low manpower and management costs. Advantages
Large-capacity storage: Provides sufficient material storage space, reduces the need for frequent replenishment, and improves production continuity.
Optimize material flow: Through reasonable structural design and auxiliary devices, the smooth flow of materials is ensured, and clogging and bridging are reduced.
Wear-resistant and durable: Made of high-quality materials to extend service life and reduce maintenance costs.
Safe and reliable: Equipped with multiple protection mechanisms, such as overload protection, short circuit protection, etc., to ensure the safety of personnel and equipment.
Easy to install and maintain: The compact design makes it easy to integrate into existing production lines and facilitate maintenance.
Intelligent management: Some models are equipped with load cells and other monitoring devices to support remote monitoring and automated control, improving the intelligence level of the system.
Good environmental performance: closed storage avoids flying dust and reduces environmental pollution. Usage Scenarios
