Indirect Rotary Drum Coolers - for cooling hot bulk materials - RKT

Product catalog summary

Overview: The document provides detailed information about the Rotary Drum Cooler type KTR, designed for medium temperature ranges. It highlights the cooling process, applications, benefits, and technical specifications of the cooler.

Specifications: The KTR rotary drum cooler channels cooling air through numerous small-diameter tubes, cooling hot, powdery solid materials as they trickle between the tubes. The drum's inclination facilitates the movement of hot material from infeed to outfeed, effectively cooling products in the 250-300 °C (480-570 °F) range.

Applications: This cooler is typically used for cooling gypsum and processing ground slag in the cement industry. It is also suitable for other powdery products requiring cooling before further processing.

Benefits: Key advantages include heat recovery from hot solid materials, primary energy and fuel savings, short pay-back time, robust design, dust-free waste air, and elimination of waste air filter systems. These features contribute to reduced production costs and environmental protection.

Cooling Process: The indirect cooling method involves moving hot solid material on one side of a separating wall, with air cooling the wall from the other side. This method avoids direct contact between air and bulk material, eliminating the need for filter systems and allowing for inert operation if required.

Technical Details: The KTR cooler's large heat exchanger surface area is achieved through numerous cooling tubes, enhancing its effectiveness. The document also mentions the RKT cooler for high-temperature applications, capable of handling products up to 1100 °C (2000 °F).

Contact Information: The document provides contact details for Allgaier Process Technology and its subsidiaries in Germany, Sweden, Spain, and the USA, offering support and further information.

Cooling hot bulk materials with indirect rotary drum coolers The application Many bulk materials such as powdery or granulated products have to be cooled before further processing, either due to the limited: • temperature resistance of the downstream equipment or the • silos and packaging containers or for • heat recovery from the hot product. The hot products can be cooled convectively by contact with air (or other process gases, e.g. nitrogen). In this process, the cooling air flows around or through the products in direct contact. The fine solid constituents that are carried along in the cooling...

Indirect Rotary Drum Coolers - for cooling hot bulk materials - RKT-3

Rotary drum cooler type KTR for the medium temperature range In the rotary drum cooler type KTR, the cooling air is channeled through a large number of small-diameter tubes and the hot, powdery solid material is cooled as it trickles in between the tubes while the drum rotates. At the same time, the hot material moves from the drum's infeed towards the outfeed due to the inclination of the drum. The large number of cooling tubes creates a very large heat exchanger surface area, which is why the KTR rotary drum cooler can also be used very effectively for cooling hot products in the 250- or 300...
