Single Unit
CAPACITY:
70 - 100 tons per hour cooled aggregates from +45°C to +11°C options.
Chilled stone delivery temperature approx. 6 - 8 degrees above the delivered chilled water temperature.
SPACE REQUIRED FOR INSTALLATION:
2 containers 40 feet high cube – one above the other
TECHNICAL SPECIFICATIONS:
- energy savings 30 – 50 % less energy compared to concrete cooling with ice
- extremely small footprint, just the space of single 40 ft container
- no special foundations required
- no settling ponds required
- cooling of the dirty slurry water via a separate heat exchanger
- water is circulated in a closed loop
- due to the special shape of the HydroSpiral, no fine particles are lost
- saving on additives (depending on the recipe 7 to 20 %)
- plug and play installation
- total electricity approx. 20 kW
- aggregates feed hoppers, feed belts and extraction belts all separate
Coldrock HydroSpiral CHS 
Coldrock HydroSpiral CHS Additional Coldrock - Components
Coldrock Heat Exchanger - CHE
The ColdRock heat exchanger is a 3 stage water to water heat exchanger utilising the clients existing chiller to provide the chilled water as the cooling medium.
The system is designed for handling and chilling heavily silted & warm water from the HydroSpiral with total cooling plate capacity approx. 550kw*. The water from the HydroSpiral enters the heat exchanger warm and dirty and is pumped back to the HydroSpiral cold and dirtry in a closed loop design. Dirty water temperature is reliant on the supply chilled water temperature with dirty water return temperatures of 7-15deg C possible.
* larger cooling capacity available
Coldrock Heat Exchanger - CHE Coldrock Dirty Water Chiller - CDWC
The ColdRock Dirty water chiller is a self-contained 3 stage dirty water ammonia chiller with rated capacity 550kw*.
The system is designed for handling and chilling heavily silted & warm water from the HydroSpiral with total cooling plate capacity approx. 550kw*. The water from the HydroSpiral enters the heat exchanger warm and dirty and is pumped back to the HydroSpiral cold and dirtry in a closed loop design. Dirty water return temperatures of 1-5deg C possible
* larger cooling capacity available
Coldrock Dirty Water Chiller - CDWC Containerized Coldsilo - CCS55
The ColdRock CCS55 is a 55ton capacity containerised aggregates storage silo.
The silo is installed with 2 stage dewatering the first being a static sieve cone and the second a dynamic dewatering screen/shaker table. Post cooling is available through sprinkling of the chilled aggregates with chilled water to maintain cold aggregates temperatures indefinitely. Aggregates are discharged from the silo though a pneumatically operated discharge gate to either an extraction conveyor or to a chute for wheel loader feeding.
Containerized Coldsilo - CCS55 Coldsilo incl. Weighing - CWS40
The ColdRock CWS40 is a 40ton capacity containerised aggregates storage silo with internal 2000kg aggregates weighing hopper**. The internal aggregates weigher in the silo is connected directly to the mixing plant batch controller appearing as an extension to the existing mixing plant as an additional weigh bin.
The silo is installed with 2 stage dewatering the first being a static sieve cone and the second a dynamic dewatering screen/shaker table. Post cooling is available through sprinkling of the chilled aggregates with chilled water to maintain cold aggregates temperatures indefinitely. Aggregates are discharged from the silo though a pneumatically operated discharge gate to a delivery conveyor bringing the cold & weighed aggregates to the clients existing inclined belt which brings the material directly to the mixer.
** larger capacity weighing hoppers available
Coldsilo incl. Weighing - CWS40 Coldsilo incl. Weighing - CWS80
The ColdRock CWS80 is a larger 80ton capacity modular aggregates storage silo with internal 2000kg aggregates weighing hopper**. The internal aggregates weigher in the silo is connected directly to the mixing plant batch controller appearing as an extension to the existing mixing plant as an additional weigh bin.
The silo is installed with 2 stage dewatering the first being a static sieve cone and the second a dynamic dewatering screen/shaker table.
