For aggregate particles, the equivalent particle size is represented by the equivalent Feret's diameter of the projection contours. The thickness of the coarse aggregate has a great influence upon the measurement results of PSDs and can be measured using the LHPMS in Fig. 1.Multiple height contours of each particle were …

Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

Types of crushers. Most crushers used for aggregate production can be categorised as one of three main types: 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.

Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.
