During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.
Step 3 Keep regular records on your mill. Most mill control panels will show transducer readouts from various inspection points, and even give alarms at 'high' and 'low' warning set points before the mill is tripped on 'highhigh' or 'lowlow' alarm settings. This is a useful function to protect the mill, but the 'high ...
