PTSM series – our expertise in screening technology

Powerful, robust, individual – Made in Germany

Individual screening machines to your specifications

Whether pre-screening, heavy-duty screen or a 6 m long 3-deck screen for sand and chippings: we design and build our PTSM screening machines in Lengerich, as a single machine or as a complete screening station with integrated conveyors.

We turn your requirements for grain separation into reality and adapt every screening machine individually. This results in screens that fit exactly into existing plants or differ from the series only in modified mounting points. From joint planning to manufacturing and final assembly, we work closely with you.

A question of possibilities

The right screening machine for your application

Screening machines are used in many applications, and the materials to be separated are just as varied: limestone in the quarry, pre-screening ahead of a large impact crusher or screening in recycling and scrap. Every application requires suitable screens and screen media. We design your screening machine and advise you individually on your product and material.

Customised to your requirements

Your idea – individual implementation

Individual adaptation

We adapt the drive concept, dimensions, mounting points and many other details to your plant and product.

  • New screening machines to fit existing plants
  • Different mounting points without plant conversion
  • Screen media matched to material and final grain size

Replacing existing screens

If your existing screening machine is no longer productive enough or fails frequently, we replace it without complications.

  • Functional components such as motors and screen supports can often be reused
  • Cost-effective replacement
  • Higher productivity of your plant

Repairs and spare parts service

On-site service

With our team of fitters, we get your screening machine running again quickly.

From bearing replacement and new shafts to replacing the side wall, we carry out most of the work directly on site. We supply spare and wear parts for screening machines from many manufacturers so that your screening technology runs economically.
