In the 1960s, grates at 5° or horizontal were employed. Grates for over 1000 tonnes per day clinker output are commonly constructed in two separately-driven sections, the first (hot) part being sloped at 5° and the second horizontal. Grates over 3000 t/d commonly have one sloping and two horizontal sections.

High cooling efficiency. The clinker can be quenched from 1300-1400℃ to below 100℃ in a few minutes. HCFC reciprocating grate cooler is one of the hot-sale grate coolers produced by AGICO. It is a kind of large hydraulic controlled grate cooler that transferred from simple speed control to speed and stroke control (i.e. PLC control).
