About Crushers Used in aggregates crushing & selection of crusher combination

With the reducing and restriction of mining upon sand resources,artificial sand is now considered as replacement that people start to use at a large scale.Meanwhile,process configuration of artificial sand crushing grows to be varied. The first process configuration among those ones tend to be selection of crushing machinery or crushing combination. For reference,we mainly focus on features and their configuration form of below frequently adopted crushers.

Features of frequently adopted crushers

Advantages：Simple structure,relatively light,low cost,easy installation and maintenance,limited crushing workshop height,stable operation,discharging gate flexible adjustment,and especially no easy to block up during operation of wet and sticky ores.

Disadvantages：easy to get worn upon jaw plate,irregular sizes and additional need of the vibrating feed.

Advantages：Small size,simple structure,big crushing ratio,low power consumption sound granularity, and flexible crushing.

Disadvantages：Easy to get worn upon hammers and screen plates: those wearing parts will be worse and need frequent replacement if ores with high hardness.

Advantages：suitable to crush materials with high hardness and high corrosive ores because ofits big crushing force and smooth in work.

Disadvantages：High investment cost, dispointing granularity.

Crushing capacity,finance status,maintenance labor,requirements upon finished products as well as sizes distribution determine selection of crushers and crushing combination forms. Regular capacity is like 200t/h,300t/h,400t/h,500t/h,while capacity over 1,000t/h is adopted by a few large enterprises.

Frequent crushing combination form is jaw crusher+jaw crusher,impact crusher+impact crusher and jaw crusher +cone crusher.
