Vacuum feeders transport materials through pipelines, enabling automatic feeding for equipment such as mixers, dryers, shredders, packers, and extruders, without occupying additional operational space.

This machine is a professional powder conveying device with a simple structure, flexible installation, and convenient operation and maintenance. Primarily controlled by PLC, the system operates according to preset parameters without manual intervention, allowing for unmanned operation. However, if design details are not properly addressed, they can affect production efficiency. It can be said that the stability of the machine in use is determined by its design details.

Vacuum feeders rely on vacuum suction to convey granular and powdered materials and are widely used in industries such as pharmaceuticals, chemical raw material processing, food and food additive manufacturing, industrial dye production, plastic processing, building materials, agricultural byproduct processing, and scientific research.

Using this machine can significantly reduce dust pollution in workshops, improve cleanliness, greatly save labor, reduce contamination, and ensure safety and reliability. Negative pressure conveying, also known as vacuum conveying, employs a fully enclosed conveying system to transport bulk materials (powders, granules), thereby eliminating environmental pollution and potential harm to operators caused by material leakage, as well as preventing external contamination of the materials. This represents the development direction of powder material conveying in recent years. The negative pressure source of this machine comes in various forms, such as vacuum generators, vacuum pumps, and Roots blowers. The advantages of vacuum generators include their compact size, lightweight design, easy installation, and suitability for use in cleanrooms. Utilizing jet technology, vacuum generators produce high vacuum under compressed air to convey materials without the need for mechanical vacuum pumps. With no lubrication components and almost no moving parts, they comply with GMP requirements.

Materials that can be conveyed by vacuum feeders include:

Raw medicinal materials, powdered materials, granular materials, mixed materials, capsules, etc.;

Grain seeds, wheat grains, flour;

Carbon powder, alumina powder, silica, bentonite, etc.;

Cocoa powder, crystalline sugar;

Pigments, dye powders, toner powders, etc.;

Clinker concrete, welding powder, quartz granules;

Polyethylene granules, PP granules, rubber granules.

The machine’s wide applicability and ability to convey various materials are primarily due to the following design methods:

Pipeline Optimization: Custom-designed pipelines and elbows for powder conveying systems reduce pipeline wear, prevent system blockages, and minimize material adhesion to walls.

Targeted Feeding Design: Reduces the adhesion rate of materials to the filter element, improving its efficiency. Additionally, manual polishing of overall钝角 enhances the system’s operational efficiency and stability.

Targeted Automatic Cleaning Design: The filter element is a critical component determining the stability of the feeder. This design optimizes the reverse blow automatic cleaning mechanism, enhancing system operational stability, reducing maintenance requirements, and extending the equipment’s service life.
