We understand process technology

  • Processing

  • Conveying

  • Separating

For processing processes - from crushing, drying, granulation and recycling to mixing, agglomeration, sifting and dewatering - we supply a wide range of products and tailor made components to fit your individual needs.

For conveying technology from cooling, heating, pneumatically transporting and aerating to conveying, charging, stacking and hardening, we provide you with intensive advice and tailor-made solutions that suit your individual requirements.

For separation processes from filtration and centrifuging to sifting and classifying, we supply cutting technology that is individually tailored to your requirements and that makes your raw materials ready for further processing.

We are HEIN, LEHMANN

Let us work together!

Since 1878, when the merchant Max Hein and the engineer Anton Lehmann sealed the founding of the company with a handshake, clear ethical principles have defined everything we do at HEIN, LEHMANN: fairness, trust and humanity.

This, as well as the combination of decades of experience in various industries with our keen interest in future technologies of all kinds, has made our work successful for more than 100 years.

From screening technology to separating technology to conveying technology – our first-class products can be customized and used in such versatile ways that they can be deployed in almost all industries: from the classic field of the stone and earth industry to the food and chemical industries, and from pharmaceuticals to the automotive and plastics industries.

This way, we are able to offer individual solutions in all areas regarding processing, conveying and separating.

In recycling too, our know-how, our quality products, and our ability to think outside the box at an unconventional level lead to innovative solutions that render a wide variety of recycling processes more efficient.

Perhaps you have already noticed: We are proud of what our family-run company has accomplished so far. We are happy about what we are doing today – and look forward to seeing what we will achieve together with you. This is our guarantee:
