An Improved Creep Model for Granite Based on the · Rock creep generally consists of three stages from start to failure: primary creep, secondary creep, and tertiary creep [13, 14] The primary creep stage begins with a high creep strain rate and then gradually decreases with time, as shown in Fig 1 The creep strain rate is a timeindependent …

The secondary crusher is the equipment that reduces the size of the materials further, after they have been reduced by the primary crusher. The secondary crusher has a size reduction ratio ranging from 3:1 to 5:1. The secondary crusher can be a cone crusher, impact crusher, or gyratory crusher, depending on the hardness, …

The two most common types are horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers are designed for primary or secondary crushing applications and can produce a cubical product with high reduction ratios. They work by using a spinning rotor with large hammers attached to the outer edge.
