It was concluded that even high-quality dark chocolates can be made by the new coarse conching process, despite the fact that each individual product requires effort for adapting recipe and processing parameters. Coarse conching means that the conventional way of producing chocolate mass—roller refining followed by conching—is inverted. A low fat pre-mix …

The noise of ball mill is also a difficult problem. Ball mill as one popular grinding equipment commonly used in chemical industry, metallurgy, mining and other industries, in the process of production, its minimum noise is 95 dB (A), up to 120 dB (A), which is one of the strongest noise in industrial production and it must be controlled.
Answer: Ball mills are used for grinding materials such as coal, pigments, and feldspar for pottery.After the material is finely crushed, it enters the ball mill evenly,through impacting and polishing to grind materia. For example, in the manufacture of …
Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
