Jaw crusher is often  used in crushing stone, but inadequate preparation before jaw crusher operating will affect the production, even in severe cases, could make the crusher  damage during using and cause  a major overhaul or re-purchase, which  is undoubtedly a great loss for the enterprise. In fact, the following four aspects of preparation work can reduce the risk of machine failure to a certain extent.

First, check if foreign body, including materials and a variety of production tools, wire, iron that left in the cavity in the last processing before jaw crusher operating. If any, must be timely taken out, or it will overload and burn out the motor or wire iron, so as to damage the movable jaw plate and static jaw plate parts.

Second, check the security measures before starting the machine.  Because safety is first in any case, and personnel injury is bad to both sides.  Taking preventive measures is the best choice.

Third, check whether the screws are loose and carrying machine foundation is too soft. Timely reinforcement ensures smooth production.

Forth, check whether the machine bearings are oiled and the lubrication oil station is adequacy. Good lubrication effects can maximize production, and the machine is also not prone to problems.
