The vacuum feeder can conveniently and quickly suck small materials such as powder or particles into the equipment through some devices. A vacuum pump will create a vacuum state inside the equipment and ensure that materials are transferred in a dust-free environment. The transportation of materials is carried out in a closed pipeline, which can ensure that external pollutants cannot enter the pipeline and cause pollution to the materials, and also ensure that internal materials will not escape from the equipment during transportation.

The vacuum feeder can transport granular and powdery materials, such as capsules and chemical raw materials. It belongs to small-scale material transportation equipment. Also, because its transportation of materials mainly relies on vacuum sealed pipelines, it ensures that the transportation of materials will not be contaminated by external environments and that materials will not escape into the air when damaged.

The transportation of materials by vacuum feeders mainly relies on the properties of the materials to determine whether they can be transported. For example, the fluidity of materials can make it more convenient and efficient for them to pass through filtering devices during transportation. The flowability of materials can mainly be judged by the stacking angle. When materials slide down from a fixed height, the smaller the angle between the conical surface formed by their complete stillness and the horizontal plane, the better the flowability of the material.

And some materials have good water absorption, which can lead to the formation of block like aggregates between materials, and may stick or block the filtering device or inner wall of the equipment, affecting the transportation of materials. Therefore, when transporting materials, it is necessary to choose a suitable vacuum feeder based on their shape, properties, and other conditions.
