A Cooler is a continuous rotary machine that reduces the temperature of Plaster, Plaster of Paris, or Anhydrite II, from a average inlet temperature of 180ºC upto 80/90ºC at the outlet. At the same time, as is it a direct type cooler, the plaster calcined with a direct fire or indirect fire kiln is re-hydrated.

Being the cooler a machine which works with the exchange of heat between the enviroment air and the product; its efficiency depends on the enviroment temperature, and the outlet Winter temperature is lower than the Summer outlet temperature.

Constructive Elements:

• 1 Tube made of steel plate.

• Inlet chute.

• Blades for stirring and advancing the product, dispossed appropriately inside the tube.

• 2 rings made of steel, monunted on nerves welded to the tube. The nerves have ventilation holes.

• 4 support rollers for the rings.

• Motor and gearbox with machine-cut gears enclosed in air-tight casing in oil-bath.

• Driven by two support rollers linked with a chain.

Being our coolers MONTERDE designed for cooling and re-hydratating the Plaster, the Plaster of Paris, and the Anhydrite II, it is possible to cool many other products if they have the suitable granulometry and inlet temperature.
