Rotary Drum Cooler

Rotary drum cooler:
it used to be named as rotary drum cooler, rotary cooler, cooling machine, cement raotary cooler, etc.
Rotary drum cooler is a cooler which be used in expanding system, good cooling effect, low noise and easy to maintenance.
This rotary drum cooler is used mainly to the matching equipment for the feed expanding. Mainly for the cooling of the expansion materials after high temperature, with operation and maintenance convenience reasonable body good cooling effect, high utilization and low energy consumption.
Rotary cooler
wide usage:
rotary cooler is suitable for cooling hot materials and getting the air absorbing lots of heat from the hot materials at the same time to make the combustion air getting to hot, for strengthening calcining and decreasing heat consumption, it's an important corollary equipment of rotary kiln. Cooling machine is the main associated equipment for rotary kiln production system. Its structure is simple but the performance is good and operating is reliable. The waste gas after heat exchange will import to rotary kiln again so as to improve the thermal efficiency of the whole system.
The advantages of rotary cooler:
1). Rotay cooler can be heated direct or indirect; the heating efficiency can be up to 95%
2). Rotary cooler operating under high temperature and low oxygen to avoid materials being self burning or exploding when drying. Big drying capacity, highly industrialization and low cost
3). Low amount of air required to save tail gas handling cost
rotary cooler is a kind of quench cooler. Its principle is to quench clinker which is laid in levels on the grate plates with cold wind from air blower. Temperature of clinker will be rapidly dropped from 1200° c to be less than 100° c. Plenty of waste gases after cooling could not only be used as secondary air in the kiln, but also be heat source for drying coal in the coal mill.
