Automatic Feeding Screw Conveyor for Powder with Pneumatic Vacuum Conveying System

Product Description

Application & Features:
The system is designed for the automatic feeding of extruder and mixer. The storage and transportation of materials are carried out in closed stainless steel containers and pipes. Some dust removal measures are taken to effectively prevent dust pollution and keep the workshop clean.In addition to storing barrel 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.
    The control system is controlled by imported PLC, and the main electrical components are imported famous brand products to ensure the long-term, reliable and efficient operation of the whole system. 

Automatic PVC compounding system is usually composed of the following subsystems: material collection system, material conveying system, metering batching system, mixing unit, material storage equipment, feeding system, dust removal system: central control system, central monitoring system ,etc.The composition and principles of the subsystems are described as below:

1. Automatic PVC Mixing Centralized Feeding System Material collection system

The conveying of the materials is the key to the automation of the compounding and 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 batching scales,the finished materials conveying from the mixer to the finished silo ,and also the finished materials conveying from the finished silo to the extruder.

2.Automatic PVC Mixing Centralized Feeding System Material storage equipment

Material storage equipment are separately silos mainly used for storing raw materials and finished materials.

PVC raw material storage silo has 150m3 of effective volume.The material touching storage materials are all stainless steel,and polished . The outside surface is done with pickling passivation treatment.Consist with silos,dust removal equipment upon the silos ,steel ladder,fences,decompression cap,gate,and other components etc.

Can automatically control the materials incoming and outgoing by setting the level gauge, it has nice appearance,strong structure,wind proof and other features.In order to ensure the qualified rate of the finished tubes, it is necessary to consider the surplus volume of the finished material's silos, normally not less than 12 hours, and also the finished material silos' design adopts the homogenized structure to ensure that the materials are not separated from the stratification.

 3.Automatic PVC Mixing Centralized Feeding System Feeding system for extruder

Feeding system is composed of vacuum feeder or screw feeder.

Vacuum feeder composed of the feeding funnel, suction gun,vortex fan, pulse filter,butterfly valve and storage silos. The biggest rated feeding capacity is more than 1500kg / h.

Screw feeder is a rodless screw conveyor,can be bend in a certain degree, suitable for the feeding for the extruder.
