Crushing 101 – Different types of crushers for distinctive needs
Cone crushers resemble gyratory crushers from the technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed.

AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training
Thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm. Typical reduction ratios are: Primary crusher: 3:1 to 10:1; Secondary crusher: 6:1 to 8:1; Tertiary crusher: 10:1 Therefore, if a 3 mm crusher product is required, maximum feed size to the secondary crusher would be 240 mm.
Box 2 Analyzing Grain-size Distribution – Hydrogeologic …
In some empirical equations the mean particle grain size and/or the inclusive standard deviation are used to estimate sample hydrogeological properties. These values cannot be derived directly from the standard grain-size distribution curve. Folk and Ward (1957) developed a method to compute these values.

Estimation of Sand Grains Crushing Rate Under Uniaxial
Several authors have defined the rate of grain crushing from the characteristics of the grain size curves [4,5,6,7,8,9,10,11,12]. These authors propose different factors to quantify the amount of grain breakage. These factors are empirical and based on changes in grain size, diameter or overall change of particle size distribution.
