ONEJOON GmbH

One step ahead with ONEJOON kiln technology

Whether for continuous or discontinuous (batch) operation – with our expertise from over 125 years of industrial furnace construction, we develop plants for demanding thermal processes to get the best properties out of high-performance and lightweight materials. ONEJOON industrial furnaces enable a wide variety of processes in the temperature range from 100 °C to 3,000 °C, and are optimized for performance and throughput. The efficient integration of the furnaces into your production process is our top priority.

ONEJOON Pusher Slab Kiln - Continuous furnace technology for high-performance materials

The ideal solution for precise and reliable mass production

The Pusher Slab Kiln from ONEJOON is the ideal solution for processes with high production capacity and strict requirements when it comes to temperature homogeneity. In addition, our Pusher Slab Kilns offer extensive control of the relevant process parameters. With a Pusher Slab Kiln, it is possible to scale up the technically demanding processes developed in a small scale without having to accept compromises in process precision (such as temperature control or comparative moderation). The modern ONEJOON Pusher Slab Kiln is energy-efficient and requires little production space. This significantly reduces not only the investments required, but also the operating costs.

For processes with high demands on gas feed and gas flow control, such as debinding or calcination, the Pusher Slab Kiln offers a modern system for gas preheating and controlled gas flow. Depending on atmospheric conditions and process temperatures, the Pusher Slab Kilns can be heated either electrically or with gas. Application temperatures of up to 2000 °C can be achieved. Both direct and indirect cooling or even active gas cooling with or without chemical influence on the product are possible. ONEJOON's high performance Pusher Slab Kilns have been developed on the basis of numerous simulation studies and experimental validations in close cooperation with end users.

Reliable high-tech solution for a variety of continuous and discontinuous processes

The ONEJOON rotary kiln is the optimal solution for processes and applications where high mass throughputs are to be heat treated homogeneously at high temperatures. The rotary kiln´s robust design allows the processing of a wide range of raw materials under various atmospheres. Powdery and lumpy educts, as well as suspensions, can be treated equally well. Two operation modes can be differentiated: Continuous or discontinuous. Later is also called batch operation. Depending on the kiln's design, both operating modes can be carried out by the same kiln. The rotary kiln operates well with a wide variety of atmospheres, such that air and inert gas atmospheres can be deployed equally well. The gas- and dust-tight sealing system developed and patented by us prevents an exchange of atmospheres with the environment and enables the processing of harmful substances. 

Our modularized furnace concept, combined with the long-term, multifaceted experience in heat treatment, make ONEJOON a reliable partner for developing innovative processes. As such, we cooperatively explore new thermal processes with our customers in our in-house test center or consult and support our customers where and when they need it. To quickly realize comprehensive solutions, ONEJOON uses an integrated system and strong partner network, covering the entire process chain, from the rotary kiln over the filling and cooling to the discharging technology. Due to our broad product portfolio, customers can also realize processes that require several different types of furnaces.

Recycling through pyrolysis – an overview

Resource-saving and environmentally friendly: our kiln technology makes raw materials recyclable

The pyrolysis process is being used in more and more resource-saving and environmentally friendly recycling processes, e.g. in the production of anode material for electromobility, the production of recovered carbon black (rCB) and the recycling of spent batteries or plastic waste. In this context, the saving of CO₂ emissions plays an increasingly important role, especially for organic raw materials. Pure disposal is being replaced by the recovery of a recyclable raw material with a green footprint.

Pyrolysis – an alternative that pays off twice

In contrast to mere disposal, pyrolysis technology has two advantages: it is not only an ecological alternative, but also an economic one. This is because raw material prices continue to rise. In addition, the pyrolysis trend is likely to continue as a result of the German Bundestag's decision to amend the Recycling Management Act. The public's increased environmental awareness is also making companies increasingly responsible for their ecological footprint.

We are your partner for pyrolysis processes

As with most products and new production processes that cross this threshold, the new role leads to stricter requirements for recovered carbon black (rCB) quality, plant throughput and security of supply. In terms of plant capital expenditure, this leads to a shift towards higher capital expenditure (CapEx) and lower operating expenditure (OpEx).

This means that reliable partners and suppliers are needed for modern production plants. As a technology leader and experienced industrial furnace manufacturer, we are therefore at your side with our expertise from numerous successfully completed pyrolysis projects.
