Measuring Discharge Opening
1. Stop the plant, refer to preparing to 󰘰nish
crushing.
3. The discharge opening is the distance between
the 󰘰xed and moving jaw plates at the bottom of
the crushing chamber and regulates the size of
the product material.

4. The discharge opening ‘X‘ is measured from
the top of the tooth on one jaw plate to the
corresponding root between two teeth on the
other jaw plate.
5. The opening should ideally be measured when
the jaw is closed, at a point of shortest distance
between the two jaw plates. This is when the
eccentric shaft is at its highest point but the
crusher will not stop naturally at this point.
6. The crusher normally stops with the jaw plates
open, therefore the measured distance is 40mm
(1.5in) above the discharge opening.
7. Measure the distance with the crusher stopped
and subtract 40mm (1.5in) to give the actual
discharge opening.
8. The crusher must be stationary to make
measurements.
