Sand Reclamation

CALCIFIRE®

CALCIFIRE reclamation technology enables most chemically bonded sand to be efficiently reclaimed to a quality equalling or exceeding new sand quality.

CALCIFIRE systems are also available for reclaiming clay bonded sand (green sand)

The CALCIFIRE design features combustion of the binder material in a direct-fired fluid bed chamber.

.The CALCIFIRE design features combustion of the binder material in a direct-fired fluid bed chamber which, unlike competitive units, introduces sand from the top and provides full fluidization wall-to-wall. Air and natural gas are introduced automatically through special distributor tubes as needed to start combustion. Gas levels are then reduced by PLC controller to the minimum amount necessary to maintain the preset bed operating temperature. Because most of the fuel for combustion is often the binder material itself and because combustion takes place directly within the fluidized sand, gas consumption and operating costs are kept low. Additional gas or oxygen can be added when higher temperatures are desired. Heat-resistant steel and ceramic fiber insulation eliminate the need for costly ram-up type refractory linings, ceramic membranes or temperature-resistant moving mechanical parts. Without a lining to preheat, the unit can achieve working temperature in minutes, not hours. Sand flow through the fluid bed is easily regulated for desired effectiveness. Sand can be reused in molds or cores at costs competitive with new sand costs in most areas.

Attrition-resistant sands can be effectively reclaimed using CALCIFIRE
reclamation systems.

 

Dependable offers the CALCIFIRE with throughput capacities from ½ tph (.46 mtph) to 5 tph (4.5 mtph). The CALCIFIRE unit may be supplied as a stand-alone system, or as part of a larger system, integrated with other reclamation functions as required.
