Cleaning of used sand by removing the adhesive binder coatings.. The two main purposes of sand reclamation are:. Cleaning of the mold material grain to remove binders which still adhere to it following the thermal load or are firmly affixed to the grain due to this load and removal of powdered components, i.e. separation of the reclaimed molding base material.

Using either our gas fired thermal thermal sand reclamation system, or our new Microwave Foundry Sand Reclaim System, we are capable of reclaiming your sand to your specifications! The BHM Thermal System is a fluidized bed design utilizing close-coupled fluid beds provide calcining, pre-cooling, sand cooling and sand scrubbing (in the case of green sand) on a continuous basis.

Benefits to Environment from foundry Sand Reclamation Plant. Avoids the disposal of resin coated sand. Minimizes the soil pollution. Avoids Ground Water Pollution. Avoids excessive mining. Applications . Resin coated sand is utilized in foundry to produce a casting of high precise dimensions, smooth surfaces. During casting process the resin gets burnt off due to high temperature of molten ...

HOW RECLAMATION IS DONE Sand reclamation can be termed as the process of reconditioning of used/demoulded sand in a foundry without lowering its original properties, which are particularly required for foundry application. Reclamation may be done by various methods- namely: z Attrition (Mechanical) Reclamation z Thermal Reclamation z Wet ...

From vibratory sand coolers to our DUCTA-COOL™ rotary cooling drums, GK has the right technology to improve your foundry process. Sand Reclamation. GK's VIBRA-MILL™ line of sand reclaimers quickly reduce sand lumps to minus 20 mesh with original grain size distribution and corresponding reduction in L.O.I. With proper addition of new sand, reclaimed material is clean and ready for new ...

Thermal reclamation creates expanded silica sand grains which do not go through the same expansion as new sand during every pour. In steel foundries this can limit or eliminate the need for iron oxides, zircon and chromite sands. Far less odor and smoke in the foundry during pouring because less chemical binder is needed.

Reclamation A word of caution -- many foundry workers regard the sand heap as a trash dump and discard all sorts of debris into it. Reclaimers are not designed to remove garbage. Discarded trash results in plugged-up sand orifices, equipment malfunctions, and casting de-fects. Although reclamation equipment may appear dusty or dirty, it is not a garbage disposal and functions as a piece of ...

In the thermal processing of sand, a of all binder and other organic materials are removed by oxidation. Firstly, the sand from the mechanical reclamation plant will pass through a cleaning tower which basically removes any metallic particles prior to entry into the furnace.

Thermal reclamation creates expanded silica sand grains which do not go through the same expansion as new sand during every pour. In steel foundries this can limit or eliminate the need for iron oxides, zircon and chromite sands. Far less odor and smoke in the foundry during pouring because less chemical binder is needed.

Mixed sand reclamation. Reclamation of sand protects our natural resources. By selective shake-out, the green and core sand fractions can be largely separated from each other in the production of core-intensive castings such as engine blocks. By separating the fractions both a high green sand quality and a high recycling rate in the core production can be achieved. After separating residual ...

Hot Sale Green Sand Reclamation Plant For Foundry View. We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.

Sand reclamation Various alternatives for the reclamation of no bake sand In addition to the conventional mechanical reclamation of no bake return sand with lump crushing, magnetic separation, oversize screening, and cooling to the working temperature, Küttner offers further process alternatives with an intensive jet, centrifugal or thermal reclamation in order to be able to fulfill demanding ...

Sand reclamation System solutions from a single source, from the project idea over consulting and engineering, up to the turn-key plant. One focus of GUT foundry plant construction is the sand regeneration for mono and mixed sand systems in the nobake area. Our key note is to keep the moulding material available in the foundry cycle considering economic and ecological aspects. Thus we ...
