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.
4. Humidity sensitivity: All materials are hygroscopic. Moisture sensitive materials may change fluidity due to hygroscopic caking, or even stick to the pipe wall or filter surface, causing pipe or filter clogging.
5. Explosion hazard: When the powder is mixed with air and reaches a critical concentration, once there is a spark, explosion will occur. It is difficult to control the concentration of materials during transportation, which can be controlled as oxygen and spark. Inert gases are used to protect and isolate oxygen, which can control the risk of sparks by eliminating static electricity.
6. Toxic: Toxic leakage will cause environmental pollution and personal injury, so reliable technology and equipment must be adopted in the transportation process to avoid. Vacuum feeders are a safe choice because the pressure inside the transport system is below atmospheric pressure, so there are no leaks. In addition, transportation system emissions must be reasonable harmless treatment, discharge standards;
7. Corrosion: Some powders are very corrosive, so it is necessary to choose the right material to make the vacuum feeder.
About Transportation
After you place the order and pay the deposit, we will start to arrange the production and contact the ocean freight transportation agency to reserve the position. Two days before the end of production, you need to complete the final payment. Then, we inform the ocean cargo transportation agent company that it is ready to come to the factory to pull the goods to the port. On the day of delivery, we will send the customer the factory video and pictures, and mark the corresponding English name of each product and product parts with a marker to prevent the customer from not knowing what each part is after receiving the goods. At the same time, we will put the English version of the product instructions in the cargo box. We generally select freight forwarders with preferential prices for customers to deliver goods for you. The shipping method can be FOB or CIF. You can also choose EXW, and then contact the goods agent company yourself.
