The Gates' gyratory crushers were preferred by the mining industry for almost two decades until the turn of the century, circa 1910, when Blake's jaw crushers saw a resurgence in popularity. The demand for large-mouthed jaw crushers skyrocketed as the industry began to understand their potential as primary crushers in rock quarries.

Compression crushers – which squeeze the material until it breaks. Impact crushers – which use the principle of rapid impact to shatter material. A ttrition crushers – which use both impact and grinding to shear material. Jaw crushers, cone crushers, gyratory crushers and roll crushers all operate on the compression principle.
