In modern clinker coolers, the cooling air passes through the clinker at right angles, whereby the air absorbs the thermal energy. Via the kiln hood, this recuperated heat is passed to the rotary kiln as secondary air, or as tertiary air via the tertiary air duct. …
Cement clinker was produced in laboratory using the same ingredient as actual production, comparing with the ones which incineration residue of glyphosate waste mother-liquor was added in. The products were characterized by XRD, and the results showed that the main constituents were not changed. And some of the main performances were tested according to GB standards.
In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.

Claudius Peters Clinker Crushers. The hammer crusher is the standard solution for crushing clinker. Claudius Peters has been supplying hammer crushers worldwide for capacities up to 6000 t/d since 1955. Claudius Peters developed the roller crusher for use in clinker coolers at the end of the 1970s. Today, the roller crusher is the standard unit for crushing the clinker inside the clinker cooler.
The essential characteristic of a grate cooler is a layer of clinker spread on a more-or-less horizontal perforated grate, through which cold air is blown. The grate is made of steel, and the cold air keeps it sufficiently cool to avoid melting or burning. The clinker progresses through the cooler by moving more-or-less horizontally along the grate, and so the direction of the cooling air is ...
