appropriate style and size of the equipment, but also in the configuration of the mill's internal components. Three Key Factors: 1. The screen, or bar grate, provides up to 70% control over the finished particle size in the majority of hammer mill applications. Once material enters the grinding chamber it must be reduced to a size small
Size reduction Size reduction is a process of reducing large solid unit masses - vegetables or chemical substances into small unit masses, coarse particles or fine particles. Size reduction is commonly employed in pharmaceutical industries. Size reduction process is also referred to as Comminution and Grinding.
In order to evaluate improvements to the size reduction process, hammer mill grinding tests were conducted using a small-scale commercial grinder with a nominal power rating of 85 hp (63.4 kW). This scale of testing is ideal to evaluate the effects of grinder configuration and process parameters on grinder capacity and efficiency. The ...
