Gold Mine Mining Machinery is a mining machinery manufacturing factory that has been established for many years. It not only has good quality, but also fair price and good service. Henan Gold Mine has a good reputation among users in Henan and surrounding areas, has obtained multiple product certifications and honors, and has obtained multiple product certifications And honor. Today, Gold Mine will tell you about the low-strength and easy-to-break points of the jaw crushers toggle plate.

Jaw crushing machinery is widely used in mining and smelting Building materials, roads, railways, water conservancy and chemical industries, crushing various materials with a compressive strength of not more than 320 MPa. The jaw crushers bracket is low-strength and easy to break, that is, when the crusher is overloaded, the brackets stress agile zone Because the stress rises sharply to the limit value, it breaks by itself, blocking the power transmission and preventing machine damage.

Even if it is protected when overloaded, because the crusher is in an accident state, The machine cannot be operated before cleaning, disassembly, and replacement, which will inevitably cause interruptions in the process and delay production. The hydraulic protection system can ensure the safe operation of the machine, even if the action valve in the system fails to operate, and the energy storage device has both The buffer function can make the thrust plate move to the right when overloaded, and realize the power failure alarm through the pressure relay. In the frequent overload situation, the hydraulic overload protection of the jaw crusher has obvious advantages. The advantages are as follows: restart, plunger injection pump The oil filling starts, the action valve has no oil drain, the working cylinder automatically returns to the original setting position after 62s, the pressure gauge reading rises to 15MPa after 88s, and then the pressure gauge reading base remains unchanged.
