E-plate elbow mobile crusher of the upper and lower jaw plate nesting campaign promoting the role, and its upper level lower than itinerary, easily broken bulk materials, and therefore broken more efficient than plate. Its disadvantage is that the jaw plate wear faster, and the materials have been smashed phenomenon energy consumption increased.
To protect the machines because of the important parts not damaged by the overload, often simple shapes, sizes smaller board design for the elbow weak link in the machine overloaded when it first occurred deformation or fracture.
In addition, to satisfy the needs of different size markers compensation and the requirements of the jaw plate wear, but also created nesting population adjustment device, usually at the plate in the elbow between the rack and release after adjusting pads or wedge iron. But in order to avoid damage due to the replacement of broken parts and affect production, may also have hydraulic device to achieve insurance and adjustments. Some jaw crusher also directly driven by hydraulic transmission fixed jaw plates, in order to complete the broken material movements. These two types of devices used hydraulic transmission jaw crusher, often collectively referred to as hydraulic jaw crusher.
