Annular Cooler

Annular Cooler – Efficient Pellet Cooling and Heat Recovery for Sustainable Production

The Annular Cooler is a critical piece of equipment in pellet production, designed to efficiently cool high-temperature oxidized pellets after they exit the rotary kiln. By rapidly lowering the temperature of the pellets, the annular cooler makes them easier to handle and ready for further processing. In addition to its cooling function, the cooler plays a vital role in heat recovery, capturing heat from the hot pellets to pre-heat incoming materials, thus reducing overall fuel consumption and improving energy efficiency across the system.

Built with precision engineering, the annular cooler features several key components: a driving mechanism, rotating parts, support rollers, side retaining rollers, pressure rails, a frame, bellows, and a cover. Its design includes a dual-drive system, ensuring synchronized operation for smooth functioning, while the auxiliary drive mechanism provides added security by enabling low-speed operation in case of a malfunction. The rotating section, the heart of the cooler, efficiently transfers material from the inlet to the outlet, ensuring continuous, high-quality cooling and discharge.
