Grinding methods and grinder types. There are four main grinding methods: impacting, grinding, crushing and sawing (see Figure 6-15). Impacting is suitable for hard and brittle raw materials, such as maize feed; sawing is better for large and fragile feed; and crushing and grinding are used for tough feed. Table 6-2
