Chip wringers (or chip centrifuges) dry chips from machining or grinding sludge to recover valuable coolant, and increasing their scrap value. These chip processing solutions can generate a rapid p... Power: 7.4 hp.
Centerless grinding Nd–Fe–B sludge was selected as the starting material from a variety of sludges in order to improve the recycling efficiency. Calcium chloride (CaCl 2 ) powder was introduced to assist the chemical reactions and reduce the usage of calcium granules, thereby reducing the recycling cost.
Rane and Date (2017) used a combination of compaction and sintering for waste obtained from forging scrap and grinding sludge. Before sintering, the grinding sludge was dried and mechanically treated by ball milling resulting in powder of about 5 μm – 10 μm. Additionally, graphite was proposed as a carbon source for carbothermic reduction ...
Our soft scrap division is handled by Tungco Powder Procurement. With Tungsten Carbide Sludge, knowing your Tungsten content is paramount. So, we strive to provide our suppliers with a prompt, accurate analysis. No percentage of Tungsten Carbide Sludge will be too high or low: wet or dry, 20% W or 90% W, we buy it all.
Generally, stainless steel grinding sludge ranging about 10,000 are generated per a year in Japan, and most of it is discarded or re-melted with scrap steel. …
Grinding sludge is transferred from the machine into the briquetter. Step 2. The sludge is compressed—squeezing out excess oils and fluids—while transforming the metal chips into metal briquettes. Step 3. The oil pressed out during the briquetting process is pumped directly from the briquetter into tanks. The oil passes through a filter so ...
Tungsten carbide grinding sludge: Can you tell the quality of the carbide soft scrap without sending it to a lab? No, you cannot. A niton gun reading is likely to be way off But because tungsten carbide sludge is so heavy, you can estimate the quality of the carbide sludge by its weight. Very heavy is very good: not so heavy is not so good.
Tungsten carbide sludge, is also known as swarf, powder, or dust. It is a byproduct from the grinding, cutting, shaping, and forming of the manufacturing of tungsten carbide tooling, inserts and wear parts and other carbide items. We accept carbide sludge that contains a minimum of 50% tungsten with a cobalt binder.

A method of and an apparatus for compressing the grinding sludge, which is effective to compress the grinding sludge to provide an intended rigid briquette even though the grinding sludge contains ground chips of hardened iron and/or steel materials and an oil-based coolant and also to facilitate reuse of the briquette (B 1 ) as material for production of steel.
soil pollution generated through grinding sludge (GS). The scrap produced from iron industries is easily recyclable. On the other hand, grinding sludge (GS) contains other im-purities which cannot be recycled again in the form of iron. Occurrence of Fe 2O 3,Al 2O 3, SiO 2 and CaO phase in GS makes it good reinforcement content with aluminium alloy.

Common treatments for wasted include grinding sludge, metal powder, mill scale and other metal soft scrap. In WM Metals and Alloys, the treatment of these so-called wastes includes grinding emulsions and oil so it can be separated from solids such as …
Sludge ("grinding swarf"): we buy tungsten carbide grinding sludge, also referred to as grinding swarf, that contains oil and moisture. Carbide sludge usually contains 60-70% tungsten and 10% cobalt. We base our price on the amount of tungsten recovered.
Up to 300 tons of grinding sludge per year. In Thyrnau, 35 grinding machines currently produce between 250 and 300 tons of grinding sludge per year. About half of it is made up of steel particles, which ultimately are microscopically fine steel chips, with grinding wheel abrasion and the other half is grinding oil.
The grinding sludge as Nd magnet scraps is effectively decarburized to a level of less than 0.03 mass% without generating any iron oxide by heating at above 1073 K …
