ball mill scale up chemical reactions nepal

• The scale of the chemical synthesis is related to the type of reaction the available ball mills and the size of the milling beakers It is rather recommended to start the reaction at a small scale ≤ 10 mmol and in case of success perform an upscaling • The filling degree of the milling beakers is essential for the energy entry
