2. Current Techniques For Sand Reclamation 2.1 Mechanical attrition:-[3] Attrition using mechanical vibrators/crushers breaks down used sand lumps into sand grains and part of the fine binder is removed by dust collector. The reclaimed sand is delivered at sufficiently low temperature useable for core/mould making.
The hydroseparator sand was pumped to the first of two conditioners, where sodium carbonate and sodium silicate were added. The discharge from the first conditioner flowed to a second unit, where the fatty acid was added. ...

Industrial sand is the main component in chemicals such as sodium silicate, silicon tetrachloride and silicon gels. These chemicals are used in products like and industrial cleaners, to manufacture fiber optics and to remove impurities from cooking oil and brewed beverages.
d) Fine mill scale (FeO): special additive for improving hot strength of sand mould e) Biomass – Dry Cow dung: 2% added for improving permeability of mould f) Manure – Dry Horse dung: 2% added for improving permeability of mould Sodium Silicate Sands mould preparation Sodium silicate (Na 2O.mSiO 2.nH 2O) is also used as special additive in ...
Reclamation by Drying and Secondary Attrition By the late 70's, early 80's, another form of reclaiming silicate-bonded sands became popular which relied on 'drying' of the sand after primary attrition to de-hydrate the binder and thus making it brittle. A secondary attrition cell was then used to impart 'work' or 'energy' in various
sodium silicates were reported to be within industry guidelines with the exception of alumina in the product using the Swan River Formation sand. SILICATE DISSOLUTION TESTS . Liquid sodium silicate (water glass) was produced in a 2-litre pressure autoclave. Solids to water ratios of 2.5:1 were mixed for 5 hours at an average temperature of 170°C.
sodium silicate and sulfuric acid are added. The mixture then enters a series of spiral classifiers where the impurities are floated in a froth and diverted to waste. The purified sand, which has a moisture content of 15 to 25 percent, is conveyed to drainage bins where the moisture content is reduced to about 6 percent.
This invention provides an attrition resistant catalyst composition and method for producing such composition. The catalyst is comprised of an acidic zeolite, rho or chabazite, and a particulate binder, kaolin, bentonite, alpha-alumina, or titania, which can be optionally modified by treatment with a compound containing Si, Al, P or B.
Attrition scrubber named as attrition cell is used to scrub the pulp with a concentration of 65-70 and to scrub the mud and fine sand on the ore Dispersing the slime in ores to remove the impurities on the ore surface can create conditions for subsequent mineral processing and is an important part of mineral processing production line...

Sand Treatment. Our Foundry Sand Treatment is used as a lubricant and internal release agent for Green Sand, Core Oil, Hot Box and Sodium Silicate sand mixes. It reduces sticking; promotes core oil dispersion in a muller; increases sand flowability and reduces clean-up of sand handling equipment.
The disposal of waste foundry sand has become one of the most pressing problems for the foundry due to environmental regulations. Used core sand dumping in valleys, rivers and lakes caused the water and soil,even the ground water pollution due to the presence of the dissoluable sodium silicate and ester in the used core sand.

Sodium Silica Sand Casting Rocks!* Fewer Failures* Faster Results* Bigger Castings* Less Equipment* No storageResources:Foundry Practices
Here, the binder employed was the usual sodium silicate. Most advantageously, this step removes those impurities which create a "slime" in the slurry subsequently employed in the practice of the invention. ATTRITION MILL. The third step involves water washing of the scrubbed sand particles which removes substantially all the remaining binder.

A representative feed sample of White Silica Sand was wet-sieved in order to recover the desired fractions for glass making. BIS specification shows that (–600, +300) μm] fraction [A] should not be more than 50% and (–300, +125) μm fraction [B] should be 50% minimum. The mass percentage of A and B is found to be 29.9 and 70.1% (ratio =1:3.34) which satisfies the size …
ARTICULATED SAND MIXERS. # Where heavier viscocity liquids are being used (i.e Sodium Silicate) a 25% reduction in throughput is likely to be experienced. * This dimension can be made to suit the individual application. @ For 13' or 20' arms, add 39.4" or 118" to these dimensions.
Sodium silicate was used to decrease the sintering temperature of the layer coated with coal refuse and to increase the bonding strength between carbon in the coal refuse and the pelletized residue. The use of coal refuse as an energy source has two advantages: a decrease in the operational costs and the recycling of mine waste.
