AZO-Systems transport raw materials fully automatically to mixers, extruders, compounders, granulating and dispersing systems, coating units, blown film extrusion lines right up to injection moulding machines and compactors. Future-proof process engineering and innovative process technology coupled with trend-setting process IT ensure the highest standard of quality – made in Germany.
We plan, produce and install machines and systems all over the world. Our systems make sure that all recipe components reach the correct processing operation at the right time and in the right quantity. Our customers benefit from the high quality and reliability of our solutions as well as on more than 65 years of experience in automatic material supply.
Automatic provision of raw materials during the manufacture of PVC dryblend
Besides the major component PVC all raw materials except titanium dioxide and micro-ingredients are precisely dosed, weighed and fed into the heating-cooling mixer by means of the vacuum conveying scale.
With the help of a separate vacuum conveying system, TiO2 is conveyed into a buffer bin above the heating-cooling mixer from which it is dosed into a scale through a dosing screw and empties directly into the mixer. This separate scale makes it possible to add TiO2 at a later point in time.
Vacuum conveying systems for feeding the dosing systems.
With the AZO vacuum conveying system, one product input station can be used to supply several compounding lines at the same time. Depending on throughput, pneumatic conveying systems can be operated as a collective feeding system with the help of several separators and a pump. When working with raw materials with poor flow characteristics and large buffer tanks, the reliable vibration discharger in conjunction with a dosing device is a recommended solution.
AZO After Sales Service
AZO quality not only means world-class machinery and production plants. When it comes to customer service as well, you can always rely on AZO, whether it involves commissioning and assembly, maintenance and inspection or supply of spare parts. AZO has a service team of highly qualified employees to assist you with any issues and answer any queries competently. Our ethos is to ensure that your AZO system operates safely and efficiently, ensuring a maximum throughputs and minimum downtimes.
Many plastic granulates already contain dust and fibres (angel hair) upon delivery. These contaminants primarily occur through abrasion of products during pneumatic conveying of the granulate. Too high a level of contaminants can cause a number of problems in further processing. In particular accumulated clumps of angel hair have a detrimental effect on the quality of the end product and can lead to a bottleneck of products and production coming to a standstill.
Dust filtration and separation of angel hair have been integrated into AZO's vacuum conveying system and do not call for an additional step in production. There is no need to meter feeding of products.
With the increased volume of air, granulate dust is filtered out in special receivers, into which screening plates have been integrated as cascades. Any dust found in the clean air is filtered out in the following secondary filter. A primary filter is also installed in front of the secondary filter to separate fibres and angel hair.
