In fact, the product discharging size depends on the gap between fixed jaw plate and moving jaw plate. We also call ” the gap between fixed jaw plate and moving jaw plate ” as CSS (Closed Side Setting). But the CSS (Closed Side Setting) is not the finished product size. If you set CSS of the crusher as 3 mm, because of the stroke of the crusher, the max finished product size will be 4.2-5mm. It is about 1.4 times of the CSS.

As the production technology developed, it is easy to adjust the product discharging size from a laboratory jaw crusher. In order to let the operator easy and clear operate the jaw crusher, there are equipped with hand wheel or electronic button for adjusting the CSS. And the CSS indicates on the hand shank or electronic button  for help the operator to learn in advance what size of the discharged product will be obtained from the jaw crusher.
