Jaw crusher insurance device classification and details of jaw crusher insurance device is divided into: mechanical, hydraulic, electronic insurance insurance insurance device etc.. Mechanical safety device: the thrust plate for jaw crusher insurance device, has the advantages of simple structure, low cost, driving method is applicable to any kind of, but this kind of device is disposable, once damaged must be replaced, it is difficult, time consuming and reduces the production efficiency, but also the thrust plate by casting lines, without mechanical processing and direct installation, because of the influence of casting error, process and material factors, the protection to the thrust plate for the insurance piece is discrete lot, jaw crusher in normal load thrust plate breakage, while in the crusher into the non crushing matter or machine the serious overload, and even the emergence of frame cracking. In order to overcome the disadvantages of mechanical safety device, a hydraulic simple pendulum jaw crusher, the crusher is the hydraulic connecting rod device, also is the transfer of power, when the crusher into the non crushing matter or machine serious overloading, the hydraulic system will increase, if elevated to high pressure overflow valve the valve set pressure, pressure relief valve, so that the connecting rod of cylinder and piston separately, the movable jaw stop moving, so the role of insurance. With the development of production and technology, especially the widely use the motor as the motive power of jaw crusher, which created conditions for the jaw crusher insurance electronic device, when the crusher of serious overloading, motor has excessive current, the sensor sampling from over current signal into the signal analysis device, will be issued a directive, thereby protecting the crusher. Above all, jaw crusher electronic safety device with mechanical safety device is compared, action is accurate and reliable, without changing insurance parts, reduced repair workload and labor intensity. Compared with the hydraulic insurance has the structure without changing the jaw crusher, the crusher can be applied, and low cost advantages.
