Granule Vacuum Loading Machine

What is a Granule Vacuum Loading Machine?

Granule Vacuum Loading Machine is used to transport various types of granular materials. Using a vacuum pump to generate negative pressure, it precisely delivers materials such as plastic granules, food ingredients, and chemical products through a sealed pipe to a designated workstation, completely resolving the low efficiency, high pollution, and high waste associated with traditional manual feeding. Its modular design allows it to accommodate granules of varying sizes, densities, and fluidities, and supports customization for requirements such as explosion-proof, sterile, and anti-static properties.

What types of Granule Vacuum Loading Machines are there?

Granule vacuum loaders are available in various types, including manual and mobile, based on their structure and function, meeting the diverse needs of industries such as plastics, food, and pharmaceuticals.

Manual Granule Vacuum Loading Machines: Utilizing a manual crank as the core operating aid, they are suitable for small-batch, low-frequency granule transport. Their streamlined design requires no external power source, and the vacuum level and discharge valve are manually adjusted, making them flexible, cost-effective, and easy to maneuver into confined workstations.

Mobile Granule Vacuum Loading Machine: Equipped with universal wheels and a telescopic conveying tube, it features flexible transport and multi-station adaptability. It integrates a vacuum pump and storage hopper, enabling automated intake and discharge cycles via simple PLC control. Its portability significantly enhances its adaptability to production lines.

What are the advantages of the Granule Vacuum Loading Machine?

With its core advantages of being airtight and dust-free, high-speed, energy-efficient, and intelligently controllable, the Granule Vacuum Loading Machine eliminates dust spillage, ensuring a clean and safe production environment, making it an ideal choice for granular material conveying in various industries.

Protecting Granule Integrity: Given the fragile nature of granular materials, the equipment utilizes a low-speed conveying design and a large-diameter, smooth pipe to minimize collisions and abrasion during conveying.

Continuous Conveying: It can achieve a conveying capacity of 1-15 tons per hour and supports 24-hour operation. Conveying distances of up to 50 meters horizontally and 20 meters vertically meet the material supply needs of large-scale production. Dust-free conveying: Fully enclosed pipeline conveying completely eliminates particle spillage and dust flying, improving the workshop environment and reducing the risk of dust inhalation for workers.

Compatible with multiple equipment: It can seamlessly integrate with mixers, granulators, packaging machines, and other equipment. Automation is achieved through a PLC control system, reducing manual labor.

How does the Granule Vacuum Loading Machine work?

The Granule Vacuum Loading Machine utilizes negative pressure adsorption technology. Upon startup, the vacuum pump creates a stable negative pressure between the exhaust pipe and the air in the hopper. This pressure differential smoothly draws the granules from the intake port and conveys them into the hopper. Unlike powder conveying, it utilizes a larger inner diameter and smooth inner wall pipe to prevent particle breakage and clogging. A dedicated air-material separation device ensures particle deposition and purified air discharge, achieving both efficiency and minimizing waste.

What are the main components of the Granule Vacuum Loading Machine?

The Granule Vacuum Loading Machine utilizes a modular design, primarily consisting of a vacuum pump system and enclosed conveying pipelines. The compact structure ensures durability and ease of maintenance, meeting the automated conveying requirements of various granular materials. Vacuum Generation System: Consists of a vacuum pump and a vacuum buffer tank. This effectively prevents interruptions in particle conveying caused by momentary air pressure fluctuations, ensuring smooth and reliable conveying.

Suction Device: Consists of a suction nozzle adapted for different particle sizes and a wear-resistant, kink-resistant flexible suction tube. The suction nozzle is carefully designed based on particle size to effectively prevent clogging and ensure smooth suction.

Conveying Pipe: Utilizes a large-diameter, smooth-walled material such as stainless steel or wear-resistant plastic. The large-diameter design reduces friction and collisions during conveying, lowering the risk of particle breakage.

Separation Hopper: Contains a dedicated air-material separator, commonly available in baffle or cyclone types. It operates by utilizing the difference between gravity and air velocity to cause particles to settle within the separator, effectively preventing fine particles from escaping with the airflow.
