Concrete Mixing Machinery 

• Basically two patent protected types


• Multi Tray Rotating Column (MTRC)


• Continuous cooling of aggregates (MTRC) & sand (Static)


• Aggregate/ sand feeding conveyor as optional supply


• Special water-locks keep the aggregates nearly free of water.


• In the static type, static flights create necessary turbulence in the cooling media traveling upwards.


• The MTRC cooler contains a multi tray assembly attached to the central shaft & is provided with levelers & knifes.


• Available in any capacity required by customer.

• Cooling water temperature is only 1-2 degrees lower than the desired “cooled aggregate temperature”. Thus reduced power requirement.


• The water leaves the cooler from the overflow nozzle at the top end at the temperature of 1-2 degrees lower than the aggregate inlet temperature (i.e. 1-2 degrees lower than the ambient temperature) along with the dirt/ sludge etc. Thus there is near complete utilisation of the refrigeration energy in the cooling water.


• Uniform temperature of the aggregate particle instead of superficial surface cooling


• Requires bare minimum water feed rate & thus the lowest possible power consumption.


• Independent of charging / discharging time requirements due to continuous operation.


• Solids are discharged at the same temperature at reduced power consumption and thus high quality of concrete mix.


• No loss of cooling water at temperature below room temp & no loss of energy used to produce this chilled water as to what happens in batch cooling.
