Vacuum conveying is the transport of bulk solids through a pipe by using the flow of air or other gas. Vacuum transportation can be built as a pressure or vacuum system.Vacuum conveyors can be widely used in magnetic materials industry, food processing industry, plastic processing industry, lithium power industry, coatings industry, chemical industry and pharmaceutical industry etc.

Vacuum Conveying is the process of moving bulk dry materials, such as powders, from place to place within a factory using suction. The material is transferred in a network of tubing from the pick up point or source to the customers process. Most Vacuum Conveying System transfer product based on a timed interval to the vacuum receiver. At the end of the timed sequence the discharge valve can open and the material conveyed can discharge in to the process.
There are two mature technical types for vacuum conveying: dilute phase conveying and dense phase conveying, which can be matched according to different material characteristics.
Dilute Phase Conveying
Materials are fully mixed with air and flow at a high speed in pipelines. Air and materials are in nearly equal proportions. This mode is low-cost and widely compatible, suitable for ordinary non-friable fine powder such as flour, sugar, talcum powder and plastic powder.
Dense Phase Conveying
Materials move in continuous material slugs at low speed inside pipes, with much less air mixed in. The slow conveying speed greatly reduces friction and collision between materials and pipeline walls, effectively preventing friable, fragile raw materials from crushing and deterioration, ideal for blended powder, pigment and fragile chemical particles.

There are two types of vacuum conveying. Dilute phase conveying and Dense phase conveying.
Dilute Phase Conveying the material is entrained in the air stream and the is an almost equal part of air and product. This method is excellent for conveying almost any type of powder like sugar or flour.
Dense Phase Vacuum Conveying the material is transferred in slugs within the convey tubing. The material moves slower then dliute phase conveying and is excellent choice for friable product or a blend of powders.
This pneumatic vacuum conveying system has strong industry adaptability, covering multiple manufacturing sectors: magnetic materials, food processing, plastic processing, lithium battery raw material production, coatings, fine chemical industry and pharmaceutical industry. It can realize powder-to-powder transfer, raw material feeding to mixing machines, reactors, extruders and packaging machines.
Fully enclosed dust-free design: The whole conveying route is sealed pipelines, no dust flying, improves workshop environment, meets food and pharmaceutical clean production standards, and avoids material waste caused by dust loss.
Two optional conveying processes: Users can choose dilute phase for general powder to reduce investment cost, or dense phase for fragile materials to keep raw material integrity without crushing.
Fully automatic unmanned operation: Equipped with PLC timing control system, automatic suction, filtering and discharging, no manual feeding required, saves labor cost and reduces human contact with raw materials.
Wide material & industry compatibility: Adapt to all kinds of dry bulk solids, applicable to lithium battery, medicine, food, chemical, plastic and coating production lines.
Safe & clean production: Negative pressure internal operation, no outward material leakage; stainless steel contact parts support food-grade and anti-corrosion production requirements.
Flexible layout: Pipelines can bend, turn and go up/down freely, easy to match complex factory workshop layout without fixed ground track occupation.
