At a very minimum, pressure should be measured at two locations: before and after the breaker plate. Usually a screen pack is placed against the breaker plate to capture contaminants and to make sure that these contaminants do not end up in the extruded product.
According to Tlusty (2000), the most common design of industrial extrusion machines consists of a barrel with a cylindrical bore in which a screw rotates, the drive of the screw, a hopper from which granulated material is fed by gravity into the end zone of the screw, a breaker plate and screen pack in front of the screw, and a die attached to the front end.
Feed enters the primary crushing chamber and meets the rotor breaker bars, which impel the feed against the first apron lined with breaker plates. Impact with the rotor, the breaker plate, and inter-particulate collision all contribute to comminution.
The second configuration was also a two orifice die but with a breaker plate with 19 orifices at the exit of the extruder (Fig.
Type "A" up-running mills feature a two-stage reduction principle for a dual mechanical reduction using the revolving hammers to shatter materials upon entry and then further disintegrating materials against the breaker plates. Type "B" heavy duty down-running mills use heavy, reversible hammers in conjunction with a saw-tooth breaker plate to produce uniform product.

Perhaps the most important feature of the MaxCap 600 is the hydraulic control that allows for adjust-on-the-fly modifications of both the feed plate and breaker plate. A simple 15-hp electric/hydraulic power pack with analog controls provides a means to eliminate any bridging in the crusher and to manipulate the crusher's output gradation with fingertip control.
The adapter has an electrical pressure gauge, manual or motorized pressure spindle, double thermocouples for every heating zone, and a breaker plate with a twin-screen pack.
The removable breaker plate cassette on the NP15 impact crusher ensures breaker plate liners can be changed safely.
Centrifugal force causes pivoting hammers to stand at 90[degrees] to the rotating shaft, throwing material against breaker plate ridges in the feed section and then against perforated bed screens through which sized material exits.
