Grinding urad dal in a wet-grinder gives nice volume since the wet-grinder has a wide-open-mouth. But when you make the urad dall batter for idly using a mixie, the urad dal may not produce similar volume to the batter. If the quality of urad dal is very good, then rice : urad dal ratio of 3:1 cups should do fine when you grind in mixie. Add 1/ ...

The float glass process, which was originally developed by Pilkington Brothers in 1959 (Haldimann et al., 2008), is the most common manufacturing process of flat glass sheets.More than 80–85% of the global production of float glass is used in the construction industry (Glass for Europe, 2015a).In the float glass process, the ingredients (silica, …

The extraction and modification of lignin derivative from sugarcane bagasse done by soda-pulping process to solubilize the lignin present in biomass, as following: a) First step, the bagasse is washed with hot water at 80 °C, then it is dried for 4 days at 40 °C in a circulating air oven until 10% w/w moisture content is obtained, and then it ...

Dissolving more, dissolving faster. When you're dissolving a solute in a solvent, it makes a solution. For example, when you stir some sugar (solute) in water (solvent) it turns into a mixture, called sugar solution. Dissolving is a very important process in our day-to-day life. In cooking, making tea, coffee or juice, washing your clothes or ...

When looking at a surface finishing chart, you should consider how to measure finishes. You can use vapor honing and other methods to improve surface finishes. However, measuring the finish first can make sure you get the final result you need. When measuring a surface, you have two options for measuring the finish.

The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process. In this process the ground bauxite is leached with caustic soda (NaOH) to produce soluble sodium aluminate (NaAlO2), leaving the impurities in the insoluble residue. The aluminate solution is then decomposed producing Al (OH)3 ...

Moreover, the particles get smaller and smaller during the grinding process, which makes it difficult to achieve a consistent grind from batch to batch.

Prior to the severe safety and health restrictions put on Silica Sand, the term sand blasting was commonly used. Abrasive Blasting is a more general term, and aptly more appropriate because there are a variety of abrasives that may be used in an abrasive blasting process. Each abrasive possesses its own characteristics, and ultimate results.

First, the bauxite ore is mechanically crushed. Then, the crushed ore is mixed with caustic soda and processed in a grinding mill to produce a slurry (a watery suspension) containing very fine particles of ore. The slurry is pumped into a digester, a tank that functions like a pressure cooker. The slurry is heated to 230-520°F (110-270°C ...
