Recycling: pyrolysis using screw heat exchangers
Köllemann screw heat exchangers are used for the pyrolysis, a step in the recycling of plastics The use of alternative fuels and biomass for the production of fuels and CO2-neutral energy production is gaining greater importance worldwide. Whether in the recycling of green waste for the production of biocoal, for the recovery of valuable metals from battery scrap or plastics for oil recovery – Köllemann screw heat exchangers can be used in many processes for optimisation (drying, preheating) or immediately for the running of the thermal reactions. Köllemann uses adapted machines in order to be able to optimally cover the very special requirements of the processes. Köllemann - Your partner for sustainable environmental projects

Together after devastating floods in the Eifel and Ahr valley region
We AHR together; Köllemann GmbH has donated a generous amount to the Rotary relief fund for flood victims. Images of the devastating floods in the Eifel and Ahr valley region and news about the tragedy of so many people are going around the world. Our company, located in what was until recently known the picturesque Ahr valley region, has also been impaired. Even though our manufactory has not been flooded, most our employees are affected badly, as almost all of them live in the disaster area. Some of them have lost everything, others still have a roof over their heads, but they have to live with the traumatic view day to day. The destroyed infrastructure does have not only tremendous impact on the people but also for the companies of this region. Between feeling completely helpless and our overwhelming wish and unconditional will to stand together in this crisis, Köllemann has been active. Our company acquired new company cars and provided them to our employees, whose cars were just washed away in the flood. Today, Köllemann GmbH has donated a generous amount to

We are the world market leader in the field of preheaters
A preheater with a throughput of 51 tph leaves our production facility and is sent on its journey to the customer. KÖLLEMANN preheaters are used to heat up petroleum coke. Petroleum coke is a residue formed as a by-product of petroleum refining and is made of almost pure carbon. KÖLLEMANN preheaters perform the heating process and heat the product from at least 0°C to approx. 200°C. The heated petroleum coke is then mixed with hot pitch in a kneader. The paste formed is then pressed into a block shape. These blocks are then baked and represent the anode, which is used in the Hall-Héroult process (electrolysis) for the reduction of aluminium.

Food processor - cooking and roasting with screw heat exchanger
Food processor - cooking and roasting with screw heat exchanger
Köllemann has been associated with efficient solutions in the fields of conveyor, process and environmental technology for decades. Our success has been evolving due to our innovative mechanical engineering designing that perfects the principle of the screw flights. Our success is based on our ever innovating mechanical engineering designs, perfecting the worm shaft to a new variety of applications. Our Research and Development came up with a solution for the food industry as also for manufacturers of animal food. We have been concentrating on those, who continuously prepare minced meat which is mixed with other ingredients in a process. Our Köllemann self-cleaning screw heat exchanger is our answer to process technology offering several advantages. Mixing, dosing, cooking, frying, conveying in one operation The Köllemann screw heat exchanger (SWT) is the first choice, wherever preparations must be cooked and fried, ingredients added, perfectly mixed, chopped

High-temperature preheaters  High-temperature preheaters for pitch with higher melting point
High-temperature preheaters
High-temperature preheaters for pitch with higher melting point High-temperature preheaters for pitch with higher melting point Köllemann GmbH from Germany, a well-established supplier of coke preheaters for the global primary aluminium industry, is sponding to the more stringent demands that are expected to be imposed on the production of anodes in future. New environmental guidelines for the use of pitch in this field will mean it will no longer be possible to use the standard pitch currently used. Over the last two years, the company has therefore developed special machinery to allow pitch with a significantly higher melting point to be processed safely and reliably. Preheaters currently use thermal oil as the heat source, and this flows through the screw flights, the housing and the main shaft it is capable of reaching temperatures of 300-350 °C. The new development offers a high-temperature preheating screw. Heat generation is via electrically heated pipes inside the shaft that are capable of supplying approximately
