Grate cooling machine is a kind of quench cooler, Its principle is to quench clinker which is laid in levels on the grate plates,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 1200 to be less than 100°. Plenty of waste gases after cooling could not be used as secondary air in the kiln, but also be heat source for drying coal in the coal mill.

 

Grate cooling machine features a revolutionary new concept with extremely reduced maintenance costs, self regulating aeration and no more clinker ridlings. Completely new solutions and major improvements of existing concepts were found in order to introduce a fresh new approach to clinker cooling.

 

Grate cooling machine has the following features:

a highly modular design

reduced costs and time for installing and an easy upgrading

the conveying system based on the walking floor principle

no conveying elements in clinker layer; active clinker distribution; red river fighting.

a new aeration concept with Flow Regulator

controlled aeration, high thermal efficiencies; autogenous wear protection.

new sealing concepts

contact seals , no fall down clinker fines, no under-grate spillage, less height required.
