Silo vibrating bottom also known as Bin activator, is an industrial unloading auxiliary device installed at the bottom of a silo. It is specifically designed to address the issues of agglomeration, bridging, or blockage that easily occur with bulk materials such as powders and granules in the silo, which can make smooth unloading difficult. It is commonly seen in various industries including chemicals, mining, food processing, etc. Let's learn about the Silo vibrating bottom from multiple perspectives.

Silo vibrating bottom structure

The structure of the Silo vibrating bottom is usually simple and sturdy. The core components include an inverted conical vibrating dome made of stainless steel or carbon steel, a vibrating motor, flexible connections, shock-absorbing suspension devices, and fixtures and connection flanges for fixing. Some types are also equipped with components such as unloading hoppers, activators, and air discs. As the power source, the vibrating motor is the key component for achieving the vibration function.

Silo vibrating bottom working principle

During operation, the vibrating motor generates high-frequency vibrations. The vibration force is transmitted to the relevant components at the bottom of the silo (such as the inverted conical structure or activator), and then radially to the materials inside the silo. This vibration process can break the agglomerated and bridged state of the materials, improve the fluidity of the materials, and enable the materials that are prone to stagnation to be discharged evenly and continuously from the silo outlet. When the motor stops vibrating, the unloading process will also be interrupted immediately, facilitating the control of the unloading rhythm.

Silo vibrating bottom main models

Depending on the differences in structural design, the vibrating bottoms of silos are adapted to materials and silos with different characteristics, and there are many common types such as silo vibrating bottom for chemical powder compounds, stainless steel silo vibrating bottom, low - maintenance silo vibrating bottom, ATEX standard silo vibrating bottom, Silo Vibrating bottom for preventing material bridging, Large storage silo vibrating bottom system.

Silo vibrating bottom advantages and application scenarios

Compared with other unloading devices such as air-fluidized bottoms, it does not need to inject air into the silo, which can avoid the influence of hot and humid air on the materials in the silo. At the same time, it has the characteristics of convenient installation, stable unloading, and good sealing performance. In the chemical industry, it can ensure the pollution-free and stable unloading of materials such as fine chemicals and active pharmaceutical ingredients. In the mining industry, it can help the smooth discharge of heavy materials such as ores and mineral powders for subsequent processing. In the food processing industry, it can also be used for the unloading operations of materials such as flour and grains.
