Stainless steel powder vacuum feeder is a conveying equipment that uses vacuum suction to transport particles and powdery materials. It is widely used in the production and scientific research fields of food, pharmaceuticals, chemicals, ceramics, feed, pigments, and agricultural products. It can be used for conveying various materials such as silicon carbide, brown corundum, white corundum, molybdenum powder, tungsten powder, cobalt powder, nickel powder, stainless steel powder, alloy powder, powder coating, quartz powder, diamond powder, electromagnetic powder, laser powder, aluminum powder, electrolytic copper powder, grinding powder, refractory materials, luminescent powder, glass microspheres, rubber additives, sugar powder, starch, salts, soy milk powder, raw material intermediates, etc. The use of stainless steel powder vacuum feeding machine can greatly reduce dust pollution in the workshop, improve cleanliness, significantly increase productivity, and save a lot of manpower and reduce pollution.

Generally speaking, powder density and particle size determine the method of transportation that should be used. Vacuum transportation methods are very suitable for powder or granular materials. Vacuum feeders transport powder or granular materials to processing or packaging equipment, such as packaging machines, mixers, crushers, injection molding machines, etc. The use of vacuum feeders can avoid complexity, labor input, and environmental pollution.

The operating rule of a vacuum feeder is that it must be direct and concise. The transfer hopper (feeding bucket) is usually a conical shape with a filtering device and a vibration device (or blowback device) inside. This feeding bucket sucks out the product from the storage bucket or mobile hopper through a long transfer pipe and brings it into the feeding bucket. When the bucket is in an overflow state, the vacuum system will automatically release it through a set program. The material will fall from the unloading valve due to gravity or be placed into the feeding bin through a pneumatic door opening mechanism. After the feeding bucket is empty, the vacuum feeding machine works automatically through a pre-set program, and the next cycle begins again.

Vacuum feeding machines are widely used in industries such as medicine, food, and fine chemicals. Vacuum feeding machines have been developed for decades abroad. The application in our country is only in recent years. With the development of vacuum feeding machine technology, two major series of vacuum feeding machines have emerged. The electric pump vacuum feeder uses an electric pump as a movable gas source, which is more suitable in situations where there is no large compressed gas source.

Another reason is that the pneumatic pump vacuum feeder uses a radio frequency vacuum generator as power. If multiple vacuum feeders are needed in a factory or workshop, a larger compressed air source is required. Therefore, when choosing a vacuum feeder, different vacuum feeders should be selected according to their own conditions.

Characteristics of stainless steel powder vacuum feeding machine:

The stainless steel powder vacuum feeder is a new product developed on the basis of widely absorbing similar foreign products. Currently, it is an ideal vacuum conveying equipment for powdered materials, granular materials, and mixtures of powdered and granular materials in China. The vacuum feeding machine can automatically transport various materials to the hoppers of packaging machines, injection molding machines, crushers, and other equipment. It can also directly transport mixed materials to mixers (such as V-mixers, 2D mixers, 3D mixers, etc.), reducing the labor intensity of workers and solving problems such as dust overflow during feeding. It is a GMP certified equipment that promotes clean and civilized production in pharmaceutical and food factories.

The stainless steel powder vacuum feeding machine consists of a vacuum pump (oil-free, waterless), stainless steel suction nozzle, conveying hose, PE filter (or 316L stainless steel filter), compressed air blowback device, pneumatic discharge door device, vacuum hopper, and material level automatic control device. The entire system is designed reasonably and manufactured beautifully.

The stainless steel powder vacuum feeding machine is divided into two types: gap discharge and continuous discharge. Gap discharge is beneficial for reducing equipment investment costs and facilitating material level control. In most cases, we recommend users to use gap discharge. Continuous discharge is generally used for vacuum conveying of materials over long distances and large production volumes.
