Abstract batch grinding kinetics with assumptions is applied to continuous tube milling to describe the grinding performance, relating the degree of size reduction to the milling conditions including the scale-up variables. as to the scale-up effect on the degree of size reduction, the trend predicted is confirmed with that observed in industrial cement mills in reasonable agreement.
Abstract the ball mill is one of the most important equipment in the world of chemical engineering. it is used in grinding materials like ores, chemicals, etc. the types of ball mills: batch ball mill and continuous ball mill with different grinding media and different design depend on the nature of the input material and the nature of the output which i need.
