Swing Jaw Plate / Active Jaw Plate

Name: Swing Jaw Plate / Active Jaw Plate
Brand: DynaMix Power
Availability: InStock

Swing Jaw Plate / Active Jaw Plate for jaw crushers. Mn13 / Mn18 / Mn22. Supplied for mining, quarrying, cement, quoted against your crusher model or drawing.

The moving half of the chamber: driven through the eccentric shaft and the toggle, so it carries the crushing force and the reversing load of every cycle. Supplied on its own or as a fixed + swing pair cast to the same profile.

Product details

Name	Description	Material	Application	Delivery time	Price
Swing Jaw Plate / Active Jaw Plate	Jaw crusher swing (active) jaw plate, straight or curved tooth profile	Mn13 / Mn18 / Mn22	Mining, quarrying, cement	15–20 working days	USD 1.8–2.5 / kg

Price is indicative, per kilogram, and moves with the manganese grade and the weight of the casting. It is fixed on the quotation. Delivery time is production time and does not include sea freight.

Fits: the model, not the size

Every plate and casting is quoted against a crusher model and, where one exists, the drawing — so it bolts onto the existing seat instead of being fettled to fit. That covers our own PE and DC series and the imported machines most often re-lined in the field. Where only a worn part is available, the profile is measured and drawn before casting.

A different wear pattern from the fixed plate

The swing jaw travels through an arc, so the stroke scrubs as well as squeezes. That produces a wear pattern you can read: a polished, peened band across the middle of the teeth where rock is ground between the two faces, and a sharper, chipped edge at the top where the plate is thinnest and the impact is hardest.

Once the teeth have flattened the plate has stopped gripping. Throughput drops and power draw rises long before the plate is worn through — which is why a swing plate is often replaced on performance, not on thickness.

Peened teeth and a polished band: the plate has lost its bite. Expect falling capacity and rising amps.
Cracking at the toe: the thin end takes the largest stone. A deeper section at the toe is the usual remedy.
A step worn into the profile that no longer matches the fixed plate: replace the pair, not the one plate.

Straight tooth or curved (baroclinic) tooth

Swing plates are cast with either a straight tooth or a curved tooth. The curved profile keeps a more even nip through the stroke and is the usual choice for hard, brittle rock; the straight profile costs less and works in softer, cleaner feed.

Whichever you run, the swing plate has to match the profile of the fixed plate. A curved swing against a straight fixed plate is the most common reason a new set underperforms: the chamber stops closing evenly along its length and the plant quietly loses capacity.

Supplied as a plate, or as a matched pair

Single plate cut to the drawing, or a fixed + swing pair cast to the same profile and quoted with the wedges.
Replaceable tooth bars (baroclinic iron) for swing jaws that take bars instead of a solid casting.
Grade confirmed from the feed, the same way as the fixed plate: Mn13Cr2 for medium-abrasive rock, Mn18Cr2 or Mn22Cr2 for hard, blocky primary feed.

How to order

Two inputs set the price: the weight of the part and the material grade. Send the crusher model together with the drawing number, or a photograph of the worn part with a tape measure across the teeth, and the quotation comes back with weight, grade and lead time.
