Product Overview
Our vacuum conveyor is a new product developed on the basis of extensive research and incorporation of advantages from similar products available both domestically and internationally. It is currently one of the most advanced, ideal, and well-designed vacuum conveying devices for powders, granules, and powder-granule mixtures in China. The vacuum conveyor can automatically transfer various materials into the hoppers of packaging machines, injection molding machines, crushers, and other equipment. It can also directly convey mixed materials to mixers (such as V-type mixers, two-dimensional mixers, three-dimensional mixers, etc.), significantly reducing labor intensity and eliminating dust emission during feeding. It is an ideal solution for pharmaceutical and food processing facilities to achieve GMP-compliant production, supporting clean, hygienic, and environmentally responsible manufacturing processes.
The vacuum conveyor consists of a vacuum pump (oil-free and water-free), a vacuum hopper, a filter element (available in polyester membrane filter, PE filter, 316L stainless steel filter, or titanium metal filter), a compressed-air reverse-pulse cleaning device, a stainless steel suction nozzle, and a conveying hose.
Working Principle
The ZKS vacuum conveyor uses a Regenerative Blower or Roots Blower to extract air, creating a vacuum at the suction nozzle inlet and throughout the system. Powder or granular material is drawn into the suction nozzle together with ambient air, forming an air-material mixture that travels through the suction hose to the hopper, where air and material are separated. The separated material then enters the downstream receiving equipment. The conveying and discharging cycles are controlled by the opening and closing of a pneumatic three-way valve or rotary actuator, which is in turn controlled by the electrical control box.
The vacuum conveyor is equipped with a compressed-air reverse-pulse cleaning system. During each discharge cycle, a pulse of compressed air blows back through the filter element, dislodging accumulated powder from the filter surface to ensure consistent suction performance.
Features and Advantages
The unit operates in an intermittent cyclic mode. Suction time and discharge intervals can be freely set according to production rhythm, perfectly matching batch batching and intermittent feeding processes. It prevents overfeeding and ensures precise, controllable material delivery.
The entire system uses negative-pressure enclosed pipeline conveying, eliminating material spillage and dust emission. This significantly improves workshop conditions, complies with GMP clean-production standards, and prevents material waste and dust pollution.
The conveying process involves no strong compression or high-speed impact, preventing particle breakage. The original particle size and characteristics are well preserved, ensuring batching uniformity and product quality consistency.
Equipped with an intelligent electronic control system supporting automatic level sensing, timed start/stop, and automatic reverse-pulse filter cleaning. The entire feeding process runs unattended, significantly reducing manual labor and labor costs.
The unit features a simple structure and low failure rate. The standard pulse reverse-pulse cleaning system periodically removes dust from the filter element to prevent clogging. With few wearing parts, routine maintenance is simple and ensures long-term reliable operation.
With powerful suction and stable vacuum levels, the conveyor can handle various conventional powders and fine granular materials. It supports integration with multiple pieces of equipment, operates with low noise and smooth performance, and is suitable for round-the-clock batch production.
Applications
Conveying herbal powders, active pharmaceutical ingredients (APIs), excipients, granulated particles, etc., meeting clean production requirements.
Conveying flour, starch, sugar, milk powder, seasonings, coffee powder, food additives, etc.
Transferring pigments, dyes, plastic pellets, resin powders, titanium dioxide, carbon black, and other chemical raw materials.
Conveying lithium cobalt oxide, lithium iron phosphate, graphite powder, silicon-carbon anode materials, and other battery materials.
Conveying nanomaterials, ultrafine powders, functional additives, etc.
- Conveying cement, limestone powder, quartz sand, metal powders, etc.
This equipment is commonly used in conjunction with mixers, granulators, tablet presses, packaging machines, vibrating screens, reactors, and other equipment. It is one of the key devices for achieving automated feeding and dust-free production in modern production lines.
