Overview
The pneumatic vacuum feeder utilizes compressed air to generate high vacuum through a vacuum generator for material conveying. It does not require a mechanical vacuum pump and features advantages such as simple structure, small size, maintenance-free operation, low noise, and easy control.The high vacuum generated by the vacuum generator eliminates material stratification during conveying, ensuring the uniformity of mixed material components. It is an ideal automatic feeding equipment for machines like tablet presses, capsule filling machines, dry granulators, packaging machines, crushers, and vibrating screens.
The QVC series vacuum conveying feeder is a type of vacuum feeder that uses a pneumatic vacuum pump as the vacuum source.With this vacuum feeding machine, materials can be directly fed from containers into mixers, reactors, hoppers, tablet presses, packaging machines, vibrating screens, pelletizers, hydraulic granulators, dry granulators, and crushers.The use of this feeder can reduce workers' labor intensity, eliminate powder pollution, and ensure that the production process meets GMP requirements.
For vacuum feeders with level control, automatic feeding is achieved through level control and the hopper of the receiving equipment.When the material level is higher than a certain position in the hopper of the receiving equipment, the pneumatic vacuum feeder stops feeding; however, when the material level is lower than a certain position in the hopper, the feeder starts feeding automatically. This completes the feeding process for the receiving equipment.
Main Features of Powder and Granule Pneumatic Conveyor:
When compressed air is supplied to the vacuum generator, the generator creates negative pressure to form a vacuum airflow. Materials are sucked into the suction nozzle, forming a material-air flow, and then reach the hopper of the feeder through the suction pipe.The filter separates materials from air. When the hopper is full of materials, the controller automatically cuts off the air supply, the vacuum generator stops working, and at the same time, the hopper door opens automatically, allowing materials to fall into the hopper of the connected equipment.At the same time, compressed air automatically cleans the filter through a pulse backblow valve. The pneumatic vacuum feeder starts automatically when the set time is up or the level sensor sends a feeding signal.The conveying capacity of the pneumatic vacuum feeder is closely related to the conveying distance and material characteristics.

Positive Pressure Conveying System
- The positive pressure conveying system is convenient for installing branch pipelines, which can convey materials to multiple places at the same time, with high production efficiency.
- The air leakage position of the positive pressure conveying system is easy to find, and the dust removal requirement for air is not high.
- The system has small conveying resistance and less wear on the pipeline.
- The positive pressure conveying system has a long conveying distance, which can reach more than 1000m.
- Air supplement pipes can be installed inside and outside the conveying pipeline, and air supplement and blockage removal can be carried out in a variety of ways.
Pneumatic Conveying Pump
- High Energy Efficiency: Due to the reasonable fluidization structure, the material fluidization state is good, and the air consumption is significantly lower than that of similar products. After years of production and research, our company has improved the fluidization structure for many times, which greatly improves production efficiency and reduces energy consumption, helping users save operating costs.
- High Material-Gas Ratio: With good fluidization effect and low air consumption, the material-gas ratio is naturally high. Through laboratory tests, when the equivalent distance is within 500 meters, the material-gas ratio can reach more than 30Kg (ash)/Kg (gas), ensuring efficient material conveying.
- Low Material Flow Rate: The material flow rate during conveying is low, which results in small wear of the equipment's valves and pipelines and long service life of vulnerable parts, reducing the frequency of equipment maintenance and replacement.
- Strong Adjustment Function: It has various adjustment methods such as primary and secondary air intake adjustment, which can make the system operate under the optimal air consumption ratio and excellent fluidization state, adapting to different material conveying conditions.
- Unique Blockage Removal Method: It adopts a back-suction blockage removal method, which is simple, easy to implement and reasonable in operation. It only needs to lead the material-gas mixture to the silo or flue inlet through the blockage removal valve and pipeline, ensuring smooth operation of the conveying system.
- Easy Solution for Supporting Facilities: Due to low air consumption and low speed, the silo material-gas separation and filtration equipment can be smaller than that equipped with general bin-type pumps, and the air pollution caused is also small, meeting environmental protection requirements.
- Small Energy Consumption Coefficient: The energy consumption coefficient of the bin-type pump conveying system is below 65KW.h/t.m, which is more energy-saving compared with similar conveying systems.
- High Degree of Automation: It adopts a programmable (PLC) control system, and the entire working process can be fully automated. The system can be set to automatic or manual operation mode. The main control cabinet is installed in the system control room, reducing manual operation intensity and improving operation accuracy.
