Crusher Reduction Ratio - Mineral Processing Metallurgy

As an example, suppose that it is required to make a reduction of 7:1 in two stages of crushers, one a standard gyratory and the other a fine-reduction crusher. We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volume-reduction-ratio in the standard gyratory is considerably higher than it is in the fine reduction crusher.

Secondary Crushing Equipment

These big machines were designed to operate at rather coarse discharge settings, usually from 10 to 12″, and the usual practice was to follow them with gyratory crushers such as the No. 9 (21″)’ or No. 10 (24″), the over-all ratio-of-reduction for the two machines

Primary and secondary cone crushers - Uralmash

Secondary crushers are used after primary crushers in four-stage crushing operation scheme. The high material reduction ratio results in more efficient use of intermediate and tertiary crushers. The profile and basic dimensions of the crushing cavity determine the standard sizes for primary (KKD) and secondary (KRD) crushers.
