1. Perfect raw material with world-level manufacturing technology. 2. More advanced movable jaw assembly lengthens LCE service time. Movable jaw assembly, composed of high-quality cast steel structure, is driven by two big flying wheels which is also made of cast steel. Moreover, heavy eccentric axle is processed by forge mold. All of these make the JCE series jaw crusher extremely reliable. 3. Integral cast steel structure is adopted for bearing seat. Integral cast steel bearing matches well with the jaw crusher frame, at the same time, radial strength of the bearing seat is highly strengthened. However, the single bearing seat does not have this advantage. 4. Finite element analysis technology is adopted to ensure the jaw crusher more stronger.
