Kilns and Furnaces for high end processing of powders

Powder and Powder Chemistry

Industrial furnace processes for powders and powder chemistry are versatile and demanding. ONEJOON is targeting both challenges, the process requirements and also the powder handling. The focus is on important issues such as process stability, the connection to upstream and downstream units and, of course, the safety of the entire plant.

Raw materials that enter the furnace in liquid form, as syrup, as powder or granulate are equally demanding as the processes, like pyrolysis, calcination or carbonization.
Before, during and after the thermal process, the specific properties often change, sometimes several times:

  • toxic or non-toxic
  • abrasive or soft
  • explosive, reactive or inert
  • adhesive or free-flowing
  • dusty or dust-free

Taking this into account, ONEJOON designs your production process and selects suitable furnaces and heat treatment plants. Crucial for this selection is e.g. the sealing system, an appropriate loading and unloading concept with connection to upstream and downstream plant technology and an integrated waste gas treatment, if necessary.

Furnace processes for powder and powder chemistry

You will get the best out of your material!

With our customised industrial furnaces, the optimum heat treatment is achieved. For the thermal treatment of chemical powders and granulates a multitude of processes and procedures can be considered:

Plant engineering

Furnace systems, powder handling and exhaust gas cleaning

The high temperature furnace of the technology leader

Pusher Slab Kiln

Why ONEJOON is the leader in pusher plate furnace technology:

  • maximum oven length over 40m
  • high temperature sintering up to over 2000°C
  • use of ceramic and metallic muffles
  • aggressive, special or standard atmospheres

ONEJOON has already successfully built pusher plate furnaces for almost all industries and products. Novel applications such as battery powder or thin film ceramics are our latest flagship products.

Powder Handling

Supplementary plant engineering

We attach high importance to the integration of furnaces into the complete production system. A reliable loading and unloading system is crucial for an effective and sustainable process. ONEJOON takes care of upstream and downstream processes and can supply adequate product handling and conveying equipment, e. g. for:

  • weighing and dosing
  • filling and loading
  • cooling
  • unloading and discharging
  • crushing, milling and grinding
  • interim storage and filling
  • conveying

In some cases, various product-specific aspects have to be taken into account, e. g. prevention of oxygen, prevention of metals or explosion protection!

For this purpose ONEJOON offers many different solutions:

  • vacuum conveyor
  • vibratory feeder
  • screw conveyor
  • innertising systems and vacuum systems
  • dosing systems and weighing systems
  • crushers, rotary mills
  • cooling channels or cooling screws
  • big bag or container filling stations

ONEJOON has the expertise to design and choose the appropriate exhaust gas cleaning system.

Our expertise includes the project planning as well as the integration of:

  • Thermal oxidation plants (TO)
  • Regenerative Thermal oxidation plants (RTO)
  • DeNOx plants / denitrification plants
  • Fluorine absorbers
  • Filtration

ONEJOON offers everything from one source!

In addition to the combustion of organic components, combustible dust fractions are also burned
in the post-combustion if required.
