Heavy shield is installed above the movable jaw to avoid the material impact. It can effectively protect the movable jaw and its internal bearing from damaging. Jaw crushers are also used as primary crushers, or the first step in the crushing process. The rock is dropped between two rigid pieces of metal, one of which then move towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.

Heavy-duty Movable Jaw Assembly adopts heavy-duty eccentric shaft, high quality heavy-load rolling bearings and finite element software optimized movable jaw plate ensuring impact resistance and high stability of moving jaw assembly; labyrinth seal and centralized lubrication system guarantee the bearing lubrication oil is not contaminated and lubrication becomes more convenient. Therefore the assembly can have a long working time and stability.

Since the end of the 20th century, we've installed more than 10,000 crushing plant all over the world. Nowadays, European type jaw crusher has already become the most popular equipment in the world without controversy. Henan Liming Heavy Industry Science & Technology Co., Ltd. is the leading enterprise of rock & mineral processing equipment in the world.It is the first choice for hard and strong abrasion material.
