Product Description

Grate 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 degree to be less than 100 degree. 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.
