Jaw Crusher Working Design:

A Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws (feed opening). For instance, a 24 x 36 jaw crusher has a opening of 24' by 36', a 56 x 56 jaw crusher has a opening of 56' square. Primary jaw crushers are typically of the square opening design, and secondary jaw crushers are of the rectangular opening design. However, there are many exceptions to this general rule.

The crushing arena is a hazardous environment. Large material and debris can jam inside the crusher, damaging components and causing costly downtime.

Importantly, manually digging out the crusher before repairs or restarts puts workers in dangerous positions. The Mine Safety and Health Administration (MSHA) has reported numerous injuries and fatalities incurred when climbing in or under the jaw to manually clear, repair or adjust the typical older-style jaw crusher.

To prevent crusher damage, downtime and difficult maintenance procedures, the hydraulic overload relief system opens the crusher when internal forces become too high, protecting the unit against costly component failure. After relief, the system automatically returns the crusher to the previous setting for continued crushing.

A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a 'V' alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the 'V' aligned jaw plates is the crusher product size gap, or the size of the crushed product from the jaw crusher. The rock remains in the jaws until it is small enough to pass through the gap at the bottom of the jaws. ore beneficiation:http://www.hx-crushers.com/p58.html

Safety is a culture and should be championed by every worker in the operation. At the same time, management should respond immediately to each worker's safety concerns and successes, rather than monitoring only overall team efforts and targets. And, manufacturers should engineer greater safety as well as productivity into their units while accompanying their equipment with strong operational and safety training programs.

It has never been more important to consider the potential hazards of conventional, older-style crushers versus modern jaw crusher design. And even during today's challenging economic climate, safety should never be minimized due to a need to achieve lower prices or costs. Modern crusher design is a major development in safe material processing--one that allows operations to maximize productivity while putting safety first.
