Powder pneumatic conveying feeding system for mixing and extrusion machine

Application & Features:

The vacuum conveying system is a kind of conveying equipment for conveying granule and powdery materials by vacuum suction. It is widely used in the fields of pharmaceutical, food, chemical, PVC, rubber, pigment, dye, agricultural products’ production and scientific research. The use of vacuum conveyors can reduce dust pollution in the workshop greatly, improve cleanliness, improve production capacity significantly, and save a lot of labor, reduce pollution, safe and reliable.

Auto pneumatic vacuum feeding conveying systems are best employed where the product is to be conveyed from several feeding points to one delivery point. Product channelling is extremely simple and dust-free since there is no excess pressure Vacuum unit and dust collector.
The system is designed for the automatic feeding of multiple extruders. The storage and transportation of PVC compound are carried out in closed stainless steel containers and pipes. Some dust removal system are taken to effectively prevent dust pollution and keep the workshop clean. The control system is controlled by Siemens PLC, and the main electrical components are imported famous brand products to ensure the long-term, reliable and efficient operation of the whole system. The control system can automatically or semi automatically complete the whole feeding process.

The simulation screen can display the operation status of each part of the system in real time through the indicator light, and can flash the alarm for the failure part to attract the attention of the operator. The extruder adopts the combination of pneumatic vacuum feeding conveying and screw feeding. The silo is equipped with two level meters. When the lower level meter shows that there is a lack of material, the feeder will work automatically to fill the material in the large silo to the small silo. When the upper level meter shows that the material is full, the feeder will stop working and temporarily stop feeding. In order to ensure the normal and continuous operation of the extruder, a 50L small hopper is added above the extruder and a level gauge is equipped respectively. If any one of the six level meters shows a lack of material, the screw feeder will automatically start to work and start feeding until all the six level gauges light up to show that the material is full, and the screw feeder will stop working; if one level meter is short of material, the screw feeder will start working again, The whole feeding process runs automatically under the control of PLC.

Powder vacuum conveying system

The conveying of the materials is the key to the automation of the compounding and conveying feeding system. In the PVC automatic compounding system, the conveying system occupies a large proportion: Including the conveying from the bagging station to the transition silo upon the weighing scales, the composite conveying from the mixer to the composite silo ,and also the composite conveying from the finished silo to the extruder.

The system is designed for the automatic vacuum conveying feeding system of extruder and mixer. The storage and transportation of PVC powder are carried out in closed stainless steel containers and pipes. Some dust removal systems are taken to effectively prevent dust pollution and keep the workshop clean. In addition to storing silo for vacuum packages and storage function, this unit automatically handles powder package conveying, featuring easy operation, and avoiding the need to carry and add raw material at Mixer operation platform. An environment-friendly and economic conveyor system that can increase the productivity by 30%, this is the ideal model for the plastic industry.
