There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties.

Not all feed mills, of course, are equipped to pellet feeds. In 1958, these mills produced 40 million tons of feed and about 55% was pelleted. In 1968, about 70% of all commercial poultry feed produced in the United States was pelleted. In the Midwest, almost 80% of all manufactured feed is pelleted, crumblized or cubed.

Feed Size, F80: Primary crushed ore is mandatory to feed any SAG mill. Typical feed size range is 80% passing 130 to 160 mm. Softer ores will be a little finer but the finer size is not sustainable when the ore becomes hard. Precrushing to finer sizes enhances throughput as does crushing of pebbles from the SAG mill (usually minus 60 mm).

which means that there is little tendency for a crusher of this kind to choke. Some machines with a by 2 m feed opening can accept rocks m in diameter and crush 1200 ton/h to a maximum product size of 250 mm. Smaller secondary crushers reduce the particle size of precrushed feed to 6 to 50 mm at much lower rates of throughput. Spring
