②Jaw plate collision due to small interval, service life is affected.
③Dynamic adjustment and self-protection functions, visual display of plate interval, interval can be adjusted during operation.
④Crushing size can be controlled without screening test.
⑤Avoiding the collision of jaw plate, extend the service life.
⑥Jaw plate is made of high-chromium or high-manganese steel (optional).
⑦No fixing is needed. The instrument can be placed on a cement floor due to the rubber bottom and foot.
