Product Information
What is automatic Pneumatic vacuum feeder?
As we all know, the Pneumatic vacuum feeder utilizes compressed air to generate high vacuum through a vacuum generator, facilitating the delivery of materials without the need for a mechanical vacuum pump. It have many advantages, such as a simple structure, small volume, maintenance-free operation, low noise, convenient control, elimination of static electricity from materials, and compliance with GMP requirements. The high vacuum generated by the vacuum generator prevents the layering phenomenon of conveyed materials and ensures the homogeneity of mixed materials’ ingredients. It is the preferred equipment for automatic loading in machinery such as tablet presses, blenders, capsule filling machines, dry granulators, packaging machines, pulverizers, vibrating screens, etc.
Technical parameters of Pneumatic vacuum feeder:
| Model | Air consumption(L/min) | Delivery Volume(KG/H) |
| LKQD-1 | 180 | 350 |
| LKQD-2 | 360 | 700 |
| LKQD-3 | 720 | 1500 |

Feature and Benefits of Pneumatic vacuum feeder:
- simple structure, small volume, maintenance-free operation, low noise, convenient control, elimination of static electricity from materials, and compliance with GMP requirements.
Application of Pneumatic vacuum feeder:
The Pneumatic vacuum feeder automatically transfers various materials to 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, and three-dimensional mixers. This reduces workers’ labor intensity and solves the problem of dust spillover during feeding. It is equipment that promotes clean and civilized production in pharmaceutical and food factories certified by “GMP.”
Working Principle of Pneumatic vacuum feeder:
The electric vacuum feeder utilizes a direct air pump (no oil, no water) made of stainless steel, equipped with a suction light, misfeed hose, filter, letdown air blow back device, pneumatic discharge door device, direct air hopper, and automatic material level control device, among others, all woven into the entire system. The design is reasonable and the manufacture is exquisite.
The vacuum feeder employs a vortex air pump to draw air, creating a negative pressure state at the inlet of the suction nozzle and throughout the system. This suction action causes powder particles to be drawn into the nozzle along with the outside air, forming a material airflow. This airflow travels through the suction tube and reaches the hopper, where material separation occurs. The separated material is then directed into the receiving equipment.
The feeding and discharge process is facilitated by the continuous opening and closing of the pneumatic reversing valve, which is controlled by the central control center.

Maintenance of machine:
Before installation, verify the site foundation with the screen installation drawing, ensuring the flatness error of the embedded steel plate is less than 3mm. Following the sequence of sieve installation from bottom to top, adjust each link to a preliminary qualified state before proceeding with the next link installation.
Next, install the screen and adjust its relative position. Ensure that the primary and secondary vibration damping springs are vertical, with the motor axis positioned 3-5mm lower than the axis of the exciter. Subsequently, spot weld the motor bracket, spring base, and embedded steel plate. It is imperative that the two motors rotate in opposite directions, and the exciter eccentric blocks are in the same phase.
Allow the vibrating screen to run for 4-6 hours without a load, ensuring the screen body operates smoothly, without rocking or emitting abnormal sounds. Additionally, inspect the fastening status of the screen plate and exciter.

Rotary sifter VS fixed sifter:
The first process of combined alkali production involves washing and refining solid salt, with the grinding washing process serving as an example.
During transportation, raw materials become mixed with debris, especially stones, which enter the system along with the raw materials. If not promptly addressed, this situation is likely to increase the content of finished insoluble matter. Stones are prone to blocking the pump, disrupting the fluid transport of solid materials, and may even lead to complete pipeline blockages, thereby posing a threat to production. Workers often have to clean the pump, increasing their labor intensity.
To address this issue, it is necessary to employ screening methods to remove debris such as stones. In the past, a fixed screen was utilized, positioned at the outlet of the raw material slurry flow. However, operating this fixed screen was inconvenient, with poor working conditions. Workers had to manually remove stones every half hour, risking cuts from sharp iron and enduring the harsh conditions, particularly in cold winters. Furthermore, the fixed screen’s performance was inconsistent; excessive stone buildup could block the pump, leading to wasted labor and filler, detrimental to pump service life. Additionally, changing the pump would result in water expansion and loss.
Nowadays, rotary sieves are employed, with a cylindrical sieve welded at the outlet of the ball mill and rotating with the body. Rotary sieves offer easy operation, automatically removing stones and improving working conditions. They provide stable stone removal, completely eliminating the need for pump cleaning, thereby reducing the content of finished insoluble matter.
