1. IntroductionBig bag unloading station is used to discharge bulk materials in big bag. According to the big bag type, there are two types of big bag unloading station. One model is bag-clamp type and another model is bag-break type. Bag-clamp type is suitable for big bag with an outlet at the bottom and bag-break type is suitable for big bag without an outlet at the bottom. Bulk bag unloading machine is widely used in food industry, chemical industry, pharmaceutical industry, plastic industry, metallurgy industry and coating industry etc. The machine can save labor intensity, increase working efficiency and improve working environment. 2. Information required for model selection①What is the big bag size? What is the weight when it is full? Does the big bag have an outlet at the bottom or not?②What is the raw material? What is the bulk density of the raw material? ③What is the fluidity of the raw material? Is it easy caking or not?④What is the allowable height for installation?⑤What is terminal equipment for material discharging?⑥Is explosion proof required for electric part? If it is, what level?

Vacuum feeding machine is a device used for conveying materials such as plastic and rubber. It attracts materials through negative pressure, sucks them from the container, and transports them to the target location, which has many advantages. Below, we will provide a detailed introduction to the characteristics of the vacuum feeding machine. 1. Efficient and energy-saving The vacuum feeding machine has the characteristics of high efficiency and energy conservation. When conveying materials, it adopts a vacuum negative pressure method, which can absorb the materials and transport them to the target position. Compared to traditional methods, vacuum feeding machines can significantly reduce material loss and waste, thereby improving work efficiency and reducing material costs. 2. Easy to operate The vacuum feeding machine is easy to operate and easy to use. Its automatic control system allows the machine to operate automatically, requiring only a small number of personnel for monitoring. Moreover, the vacuum feeding machine is compact in size and occupies a small area, so it can be moved and installed at any time. 3.Safety during operation The vacuum feeding machine is very safe during operation and will not pose any threat. Its flexible hoses and sealing materials have characteristics such as wear resistance and corrosion resistance, ensuring the long-term stable operation of the equipment. Moreover, the vacuum feeding machine also has an automatic anti blocking function, which can effectively prevent the equipment from getting stuck or interrupting operation during the operation process. 4.Wide application range The vacuum feeding machine has a wide range of applications and can be used to transport various materials such as plastic, rubber, chemical raw materials, food, etc. Its efficient and fast characteristics have made it widely used in various fields. In addition, the vacuum feeding machine can also be customized and improved according to different industries and needs to better meet user requirements. 5. Environmental protection and energy conservation The vacuum feeding machine has good environmental and energy-saving effects. It adopts a vacuum negative pressure method, which reduces air pollution and dust dispersion compared to traditional conveying methods, reduces environmental pollution, and achieves energy conservation and environmental protection in the production process. 6. Convenient maintenance The vacuum feeding machine is easy to maintain. Its structure is simple and its components are clear, so it can be repaired and maintained at any time. At the same time, the design of the vacuum feeding machine takes into account the unity and universality of the components, making it easy to find and replace parts during the maintenance process. In short, vacuum feeding machines have the characteristics of high efficiency, energy conservation, easy operation, safety and reliability, wide applicability, environmental protection, energy co...

Pneumatic conveying systems are usually powered by air compressors, Roots blowers, or vacuum pumps, using air or inert gas as a medium to transport solid bulk materials (particles, powders, crushed materials, etc.) through connected material pipelines, using positive or negative pressure blowing or suction methods, from material sources such as storage silos, buffer hoppers, etc. to material destinations such as storage silos, packaging machines, forming machines, etc. Positive pressure dense phase transmission tank pneumatic conveying system: uses relatively high pressure (above 1 bar) to transport powder or granular solid bulk materials through conveying pipelines with relatively low air consumption. Open the feeding valve and breathing valve of the sending tank to start feeding. Feed to the high level position of the sending tank, close the feeding valve and breathing valve, and the feeding is completed. Open the compressed air delivery valve, inflate and pressurize the delivery tank, and open the pipeline booster. The conveying timing starts, and the material is transported from the sending tank through the conveying pipeline. After the delivery of materials in the sending tank is completed, the compressed air intake valve is closed. The system enters the next batch of material conveying cycle.   Advantages: Suitable for particles, powders, and mixed materials. High conveying output. Low material wear. Advanced pipeline air booster technology and unique innovative pneumatic conveying scheme make conveying more efficient, stable, and energy-saving. The conveying is gentle, slow, and has little wear. The mixture has no layering and no decrease in quality. Use lower compressed air and energy consumption. The system is simple and pollution-free. Stainless steel material, suitable for sanitary and anti-corrosion applications. Industry and Materials: Plastic related industries: Plastic raw material particles and powders. For example: PET, PE, PP, etc. • Carbon black • Food grains or fragile grains, coffee, peanut dough sugar • Chemicals • Daily chemical laundry detergent • Power plant fly ash • Pet food • Sand   Characteristics: It can almost meet the production requirements of most conveying output and conveying temperature. Suitable for: High abrasive materials. Fragile materials. Mixed materials (to minimize the occurrence of almost no layering or layering of the transported mixed materials.) Materials with a heavier specific gravity. Materials with hygroscopicity.
