Jaw crusher installation technical requirements

Jaw crusher is aggregate processing, sand making production line commonly used crushing equipment, which can be crushing big rock hardness. Powerful jaw crusher crushing force, and its assembly technology has also been a top priority. Jaw crusher assembly technologies focus on moving the jaw assembly, and the assembly work is also focused on the main movable jaw assembly, while another portion of the movable jaw assembly focused on four groups bearing. If these four groups bearing assembly must meet the technical requirements, but when loaded moving jaw wear very smooth, not hold strong, the assembly dimensions are in line with requirements of the drawings, the whole machine run this estimate would not be a big problem.
