Jaw crusher broken hard materials such as ore in the thick broken equipment, with a crushing ratio, high output, even granularity, simple structure, easy maintenance, low cost production. Jaw Crusher jaw plate move when working in direct contact with the material, which often suffer a larger load. When the crusher feed into the mouth of the process, the firm may often have special stones or broken iron and other hard objects, improper insurance documents in a timely manner if the ban this from happening, then the hard material in the crushing chamber malformations within the helpless crush, or even directly impede the operation of equipment, resulting in downtime review. And there are parts of this case the supply of the insurance protection will greatly advance all the lithotripsy equipment and production lines to the active control.
When the jaw crusher cavity can not be broken into (eg, iron, steel balls, etc.), an important component to maintain equipment is not damaged after the thrust plate to take the insurance as a crusher parts. Individual cast iron thrust plate after the whole cast, in which a slot or opening a number of holes to drop its cross-section strength; can cast two, and then link up with screws to form a combination thrust plate. But not broken material into the crushing chamber, the device generates overload scene, great crushing force to pass the thrust plate thrust plate to break or cause a combination thrust plate screws cut, the end of the machine work, play a role as insurance.
This design principle is not only very appropriate and easy to control, change insurance, cheap pieces of expense, easy operation, the overall home for the equipment from damage is also very good with.
