The size reduction takes place when the material comes between rotating and fixed blade by a mechanism of cutting. The size reduced material falls on the screen present at the bottom. The vibration of mill helps in moving of product into the outlet. The size reduced material is collected from product outlet.

GATECHmo4mark. mo. A continuous grinder obeying the Bond crushing law grinds a solid at the rate of 1000 kg/h from the initial diameter of 10 mm to the final diameter of 1 mm. (i) If the market now demands particles of size mm, the output rate of the grinder (in kg/h) for the same power input would be reduced to.

Unlike the ball mill, there is no grinding medium is used in the fluid energy mill for the size reduction of the materials. Due to the expansion of the gas in the chamber, temperature in the mill decreases which enables the use of the fluid energy mill for the milling of thermolabile substances (Lachman et al., 1987) (Fig. ).

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.

A change in transfer size can be accommodated between and mm by an adjustment using the Bond ball mill work index. Starkey found that there was no observable difference in the energy consumption in a SAG mill or ball mill in this size range. This method of estimating mill power requirement has been successful in recent years.
