Processing recycled plastic requires the use of technological capabilitie sand advanced know-how in operating particularly effective filtering processes, so as to be able to draw out plastic that is “newly” clean, pure and of high quality.

As a result, the demand for innovative automatic screen changer solutions is accelerating, leading to increasingly high-quality filtration, to guarantee a “purer” result without any waste.

The frequency in replacing filters is essential in order to achieve the highest possible level of cleanliness and purity of plastic polymers, before shaping them for a range of uses.

The means of replacement and the type of machine used for this activity impact not only on quality, but also on the speed and cost of the whole process: an automatic and continuous screen changer can raise the efficiency of the whole production chain at a company and generate an increase in business.Designed for complete filtering of thermoplastic to be used for extrusion, screen changer systems guarantee excellent results on regenerated products for companies and end users, enabling a process of high-quality processing on materials with a high purity level.

BD Plast is a company which is constantly engaged in working on the sector and in developing new solutions for extrusion, to keep up with market requests by generating new product lines.

A high-performance screen changer is a guarante of sustainability for the whole production chain: among BD Plast’s leading products we find Clean Changer®,the self-cleaning filtering system which is now made with full insulation.

Clean Changer®, the new automatic and continuous self-cleaning hydraulic screen changer with three plates, was created out of BD Plast know-how in order to provide autonomous operation and not produce any waste, enabling the reuse of 100% of the material.

By implementing a cycle of high-efficiency cleaning of the screens, Clean Changer®can guarantee a level of cleanliness which is the same as new, with a consequent further reduction in production costs.

The self-cleaning sequence of Clean Changer® is completely autonomous and managed by a PLC fitted with a touch-screenpanel, minimising the need for manual labour.

The product, which can boast the totally automatic ejection of the breaker plates, is designed and tested for application on the following processes: granulation, compounding, recycling, blown and cast films, flat sheet, pipes, profiles, strand pelletizing, underwater pelletizing, hot melt coating, and master batching.

Clean Changer®is an innovative and winning solution because it combines the reduction in costs by eliminating the downtime of the line and the waste material, as well as being easy to maintain, not requiring the deployment of any operator dedicated to the continuous replacement of the screens.
