Size reduction is an integral part of mineral processing which has the largest contribution to the energy consumption of mineral processing plants. This chapter provides an overview of size reduction theories and describes different mechanisms of breakage which are relevant in the mineral processing context, along with ore characterisationThe paper concerns investigation of the effect of impact crusher operation on selected qualitative characteristics of mineral aggregate products. Qualitative characteristics of crushing products in terms of size reduction ratio and fine particles contents were analyzed from the point of view of operational parameters of the impact Minerals Free Full-Text Optimization of Aggregate

Roll Crushers ScienceDirect
Within the same reduction ratio the power consumption of roll crushers varies widely. The power required could be expressed by the general equation (6.8) P = capacity × reduction ratio × work index. In industry, the low pressure smooth surfaced rolls are designed to draw 8–50 kW of power under dry conditions.In particular, their low reduction ratios (typically limited to about 3:1) and high wear rates make them unattractive when compared to other types of comminution equipment, such as cone crushers. There are, however, some characteristics of roll crushers that are very desirable from a mineral processing point of view.Comminution in a non-cylindrical roll crusher ScienceDirect

Crushing in Mineral Processing 911 Metallurgist
Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.Mineral Processing. Mineral processing, also known as ore dressing, mineral beneficiation, or mineral engineering, is defined as the science and art of separating valuable metallic and nonmetallic minerals from unusable gangues. Rod and ball mills have larger reduction ratios. Because rod mills provide some internal sizing action, they areMineral Processing an overview ScienceDirect Topics

Coarse comminution test-work and modeling are powerful tools in the design and optimization of mineral processing plants and provide information on energy consumption. Additional information on mineral liberation characteristics can be used for assessing the potential of pre-concentration stages or screens in the plant design.
