Sand Reclamation System
MECHANICAL SAND RECLAMATION SYSTEM
Chemically bonded foundry sand after metal pouring can be partially or fully reclaimed for reuse.
Mechanical sand reclamation.
Thermal sand reclamation.
After knockouts Sand lumps are fed to a lump reducer “Vibraclaim” where due to vibratory gyratory motion lumps abraded with each other to release the original sand grain.
The abraded sand grains and fines are then fed to classifier, where mixture is fluidized to remove fines.
If sand lumps are hot water cooled tubes are used to cool the sand.
Dust collection system collects all fines which are disposed off.
Above system is used for mechanical reclamation system. for small foundries.
Calciner
Biomedical Waste, E- Waste, Hazardous Waste
ROTARY CALCINER
Calcining is heating the material to a certain temp. for certain time and for a particular operation. Often calcining process for organic materials produces hazardous gases which cannot be left to atmosphere. Many times these gases have heating value and hence they are recirculated through a combustion chamber for heat recovery.
Indirect calciner
Products pass through a tube ,which is heated from outside , both , products of combustion and liberated gases are sucked by pollution control equipment to make them dischargeable In this system calcination under atmospheric control is possible.
Heating media can be electrical gas oil fired.
Aluminium Furnaces
REFRACTORY HEARTH CONTINUOUS MELTING CUM HOLDING FURNACE
Automatic burner and recuperator.
Bath temperature controlled.
Tremendous cost saving in melting.
Applications- gravity die casting, rotor die casting.
DRY HEARTH MELTING CRUCIBLE HOLDING FURNACE
For the molten metal requirement of 100 – 300 kg. continuously.
Separate melting zone.
Molten metal passes to crucible heated from outside.
Accurate temperature control.
Flue of crucible passes through melting zone to recuperator.
Solar Hybrid Furnace
Solar Power can be directly (DC supply) used for Heating Furnaces during daytime. These furnaces are also fitted with Automatic gas burners. As solar energy reduces, gas heating starts. Solar retakes over next day morning. This combination of SOLAR+GAS reduces operating cost up to 60% compared with Government Power supply tariff. The Cost of Investment is recovered in less than a year or even less if 100% depreciation is availed.
Quenchant Tank Agitation
Cooling Is EQUALY Important as Heating
Submersible Agitator is a key equipment for Quenchant Tank Agitation in Heat Treatment process. The Airless agitation with 0.5-2.0 m/sec. velocity resulting in 8000 C/min hot job cooling rate achieves the required properties. The Submersible Agitators are any time removable equipment, not only agitates the quenchant but offers high thrust on hot jobs, due to which vapour blanketing is instantly broken (or do not allow) and heat is dissipated at tremendous rate. It is used for Water, Water Polymer and Oil Quenching Tanks very effectively.
The performance parameters of the submersible agitators are shown in the following table with the rated voltage of 415V and the frequency of 50Hz. However special agitators with 380V ~ 60 Hz or other supply conditions are available on request.
Defoaming Furnace
Defoaming Furnace for Lost Foam Mould Sintering
Thermocol patterns are used to make ceramic mould by slurry process. moulds are dried in an oven for two hours for removal of moisture.
The molds are subjected to sudden heating at 10500 C in defoaming furnace which give rise toxic smoke fumes. Moulds are heated for one hour. The fumes pass through after burner chamber – recuperator, cooled with water in quencher, passed through Ventury Scrubber, Demister, sucked by ID fan and vented off through chimney meeting national ambient quality norms. All automatically done by PLC, HMI, SCADA.
