Hammel Plant Engineering

The complete solution!

Idea - Consulting - Engineering - Manufacturing - Assembly - Commissioning

HAMMEL offers complete solution for different kinds of materials such as wood, waste and metal in the field of plant engineering and construction. Recycling plants are designed accordingly to the individual needs of our customers - from the development to the commissioning.

It's what you want

After the decision has been made for a HAMMEL recycling plant, you will be invited to an intensive project meeting at the HAMMEL factory in Bad Salzungen.

Here your individual requirements and aims are combined with our ideas and experience.

From this moment on, a project team will be at your disposal, consisting of experienced sales representatives and design engineers, to conceive the optimal plant solution.

You communicate your needs, we develop the complete solution!

Stationary and Mobile Plant

Depending on the individual site conditions, stationary or mobile plants can be developed with a single machine unit or conceptualized with various integrated machines. In the first step of fragmentation, the input material is pre-shredded by a HAMMEL Primary Shredder.

The material can be separated with the help of magnet stations or sorting lines afterwards.

Various secondary shredders and different kinds of screening technology can be connected in series. The single machine units are linked by innovative conveying and discharge technology.

Amalgamating our best for you

We combine our best recycling technologies in building your plant.

The most powerful primary shredders ...

At first the HAMMEL Primary Shredder processes the material, like waste wood, industrial and commercial waste or extremely heavy materials, like railway sleepers, roots and stumps, paper rolls, mattresses and car bodies, creating a coarse pre-shredded material for the following processing steps.

The stationary HAMMEL Primary Shredders can be planned either as a complete machine or in component formats depending on the individual local conditions. Thereby the shredding and the power unit are separated. The machine is therefore flexible and is arranged to suit structural circumstances.

Pre-determined shaft configuration regulates the material size for further processing steps.

Separation and sorting, recycling in perfection

Valuable energy reserves are slumbering in waste. Whoever sorts it the right way, is earning cash! Potential recyclables like; metal, wood, plastics or stones are separated through sorting lines or via magnet stations. The recovered materials can be profitably sold or used for your own new products.

The HAMMEL magnet stations and sorting lines are constructed suitably for the consistency of your processing material

Screening technology

All of HAMMEL Screens are well designed with individual fitted screen decks, high throughput performances, customised fractions and are built tough against any climate or conditions. All screen segments are equipped with a cleaning system or have a self-cleaning function.

The right screen is chosen accordingly to the processed material.

How small should it be?

The HAMMEL NZS 700 / 1000 Secondary Shredder in electric and diesel version offer great energy saving and is very efficient in the processing of pre-shredded materials. According the chosen screen basket, a final product size of approximately 50 – 150 mm could be chosen. Creating an exact particle size for resale.

Discharge and conveying technology
  • Feeding and dosing bunker: This material conveying technology consists of a feeding bunker for the take up of the material and conveys it via a dosing belt continuously and equally to the following processing station or rather in the combustor.

  • Conveyer belt: The base for our conveyer and discharge belts is an intelligent construction kit system.It consists of single meter elements. In this way it is possible to offer the right length according to the local conditions.The belts are available in different versions with a belt width between 600 mm and 1.400 mm, for example as a slewing belt conveyer or with conveyer cover

  • Walking floors: Walking floor systems convey the material slowly, equally and continuously from the bunker to the next conveyer system.As soon as the defined material level has been reached, the conveying will automatically be stopped.

  • Drag link conveyer: Final products can be conveyed extreme steep and high to the next processing station or in separate boxes via drag link conveyers.

If you tell us your demands, we develop ideas for your individual plant! Idea – Consulting – Engineering – Manufacture – Assembly – Commissioning. One contact for all concerns!
