3.5. Aggregate Crushing Characteristics under Roller Compaction. Table 11 and Table 12 show the aggregate particle distribution and crushing characteristic under roller compaction for various types of aggregate. Similarly, the coarse aggregates were crushed and mainly became a portion of 4.75–9.5 mm fraction and 2.36–4.75 mm fraction.
crushing. These factors include (1) stone type, (2) feed size and distribution, (3) moisture content, (4) throughput rate, (5) crusher type, (6) size reduction ratio, and (7) fines content. Insufficient data are available to present a matrix of rock crushing emission factors detailing the above classifications and variables.
The results show that the crushing strength of limestone particles obeyed the Weibull distribution and the particle size had a relatively small effect on the Weibull modulus. The characteristic strength of the particles decreased with increasing size, but it tended to stabilize when the particle size reached 240 mm.

Pre-crushing. Before beginning to use a limestone crusher, it's essential to pre-crush the material. This will help to reduce the overall size of the material, making it easier to work with and resulting in a more consistent product. Additionally, pre-crushing will help to ensure that the material is evenly distributed before it enters the ...
Crushing Equipment. The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstream of the crushing plant (e.g. mill and grinding circuit selection).
