How to choose vacuum feeder
Vacuum feeder is a dust-free sealed pipeline conveying equipment that uses vacuum suction to transport powder and granular materials. Vacuum feeder is mainly used for conveying powder and granular materials, not suitable for conveying too wet, too sticky, too heavy materials.
How to choose a vacuum feeder?
Not all materials can be transported in a vacuum. To determine the transportability of materials, Jinjishun machinery teaches you to analyze some characteristics of materials through measurement: packing density, particle factor, packing Angle, humidity sensitivity, electrostatic constant, explosion risk, toxicity, corrosion.
1. Packing density of materials: refers to the weight per unit volume of materials in a loose state. Because particles or powders contain matter and air, the density of the particles will change according to the form of accumulation, so it is necessary to measure the density of the actual state.
2. Particle factor: refers to weight, particle size distribution, shape, hardness, etc. The fluidity of particles is the key factor that affects the flow of materials and the design of conveying system.
3. Accumulation Angle: refers to the fluidity of the material is one of the important parameters when judging the transportability of each material. It is usually expressed by accumulation Angle, that is, the Angle between the cone and the horizontal plane of the cone formed after the material is dumped from the height. The smaller the Angle, the better the liquidity, and vice versa. However, for some special materials, the adjustment Angle cannot accurately represent the fluidity.
