The document discusses factors to consider when choosing a stone crusher for a production line. Key aspects include the properties of the raw materials being crushed like hardness and water content, quality requirements for products like grain size, and desired production rate. The type of crusher chosen, such as a jaw crusher, cone crusher or impact crusher depends on the raw material properties. Production processes also influence product quality and rates.

1. crusher machine in the stone crushing production line
In the stone crushing production line, the crusher machine or stone crusher plays an essential
role. How to choose the ideal stone crusher has been an important issue for customers.
According to our experts, there are three main aspects that need our attention when we are
about to select the proper crushing equipment for ourselves:
1.Properties of raw materials
Hardness, gradation, silt content and water content are all key parameters for raw materials that
need to be crushed. When raw materials are too hard, they are ready to be handled by jaw
crushers and cone crushers as the primary crushing devices. When materials are not so hard,
they can be crushed by impact crushers as the first choice. The gradation of raw materials
influences the whole performance. For stones from pebble bed, we tend to use the primary
crushers according to materials grading curve. If necessary, allocate the screening machine. If the
silt content or the water content is too high, the wet type crushing method is needed.
2.Quality requirement for products
Product quality revolves granularity, gradation and grain shape. For different projects, there are
different requirements for the crushing products. Various stone crushers and production
processes have much influence on the product quality.
3.Production rate
The production rate or the productivity is regarded as a core parameter for the stone crushing
production line. The production rate refers to two aspects: standard particle productivity and
whole products productivity. And the former one is more influential than the latter one when it
comes to the real production.
