Place of Origin:
Rotary Cooler (Monocular Cooler) is a equipment that can cooling material via the cylinder rotating to drive material processing fully heat exchange with cool air, which have series advantages like good cooling performance, bigger capacity, high operating ratio, energy saving with environmental protection, easy operation and maintenance and long life time. The cooler can be widely used for industry fields like Cement, Quick-Lime, Ceramic Proppants and Magnesium etc.
Processing Materials: fertilizer, mineral ores, ore powder, coal ash, coal slime, coir pith, coconut fiber, coir fiber, coconut shell, etc.
Rotary Cooler Working Principle:
Clinker with high temperature goes into the cooler through the feeding device, and the cooler will rotate to drive the materials to conduct heat exchange with the air, and with the constant rotation of the kiln according to the designed inclination and rotating speed, the materials will also periodically roll and move forward inside the kiln, so that the raw materials are send from the feeding end to the discharging end and cooled to below 200℃ in the time period when the materials go through the rotary kiln.
Rotary Cooler Features:
This rotary cooler equipment can fully suck the air that is used for cooling the materials as secondary circulation air, thus improving the thermal efficiency of the kiln, and in addition, it has the features of simple structure, high running rate and convenient operation and maintenance, so that is very suitable for small-sized cement plant.
Rotary Cooler Techncial Parameter and Models:
Rotary Cooler Structure
The rotary cooler is mainly composed with Driving device, Support Roller device, Thrust Roller device, Cylinder, Inlet, Outlet and sealing device, the mainly structure features are:
1. The cooler have 2-4 support point(normally have 2-3), that will easily ensure the connecting surface of support roller and tyre parallel to cylinder axis when installation.
2. Supporting device have adopt rolling bearing that have substantially simple supporting structure, which can reduce waste power consumption and easy for change and maintenance.
3. There have adopt heat-resistance steel scales sealing device instead of old labyrinth sealing for cooler inlet and outlet, which have better sealing performance and stronger reliability, also have longer life time and easy for change.
4. There have a certain gap between tyre and cylinder, that ensure the tyre can be tightening on the cylinder to strength the cylinder when normally operating.
5. The Driving system have adopt new type AC inverter speed governing technology, compare with traditional electromagnetic speed governing and DC speed governing, it has better performance on energy saving and environmental protection, also have other advantages like large speed governing scale, high efficiency, high accuracy for speed governing and steady operation.
