Jaw crusher in the process of work, high moisture content of ore material into the crushing chamber, crusher material containing a water broken into small pieces, into small pieces of material has certain viscosity, adhesion together, and plugging in the crushing cavity between two pieces of jaw, card material phenomenon;Also may be broken material is mixed in a viscous large loose dirt, make the material be glued into a wall in the crushing cavity, the card is expected to occur.

So material during the broken into the crushing chamber, the operation of the jaw crusher is best made by through professional training of technical personnel, so that we can effectively reduce the card material.

Additional jaw crusher before use, should first clear the various parameters of the crusher used, especially for the requirements of material properties, according to the requirements of crusher for material into suitable material, if do not conform to the requirements of the crusher production process, such as high temperature or moisture content is too big, can carry on corresponding processing work first, make the material as far as possible at or near the requirements of the crusher.
