  JC Jaw Crusher Overview

  The JC series jaw crusher is the combination of the newest technology from Europe and SBM own decades’ experience and experiments. As an improved version, this series jaw crusher adopts “V” crushing cavity, making the feeding size equal to the theoretical one. Besides, the jaw plates are made tooth-shaped, which greatly increases the crushing efficiency.
• Application area: mining, construction, metallurgy, chemistry
  Processing stage: primary crushing, secondary crushing
  Crushing material: limestone, gypsum, calcite, bauxite, granite, iron ore etc. (<Moh’s harness 8)
  Crushing ratio: 4-6
  Main components: body frame, movable jaw, fixed jaw
  Working principle: with the rotation of eccentric shaft, the movable jaw keep pushing and leaving the fixed plate to crush the entering material
  Protection type: toggle plate
  Quickwear parts: high manganese steel

JC Jaw Crusher Detail Info

• JC Jaw crusher application

  JC series jaw crusher is the best choice for hard and strong abrasion material such as basalt, river pebbles. Every feature of JC series jaw crusher has been carefully designed to provide superior quality and performance. It is widely used in fields of mining, metallurgy, construction, smelting, hydropower and chemical industries etc.

• JC Jaw crusher main features and benefits

  Compared with other jaw crushers, these types of jaw crushers have own advantages as follow:
  • 1. JC jaw crushers use world-class manufacturing process and high-tech raw materials. Movable jaw assembly with cast steel components and forged heavy eccentric shaft empower it with exceptional reliability and durability.
  • 2. Axle bearing housing with integrated cast steel structure can be perfectly cooperating with the crushing frame. Meanwhile, it greatly enhances the intensity of the axle bearing.
  • 3. "V"-shaped crushing cavity makes the actual feed opening width equal to the theoretical one.
  • 4. Wedge adjustment device makes discharging process simpler, safer and faster.
  • 5. Compared to other types of jaw crusher with the same specifications, JC jaw crushers have larger and more durable eccentric shaft bearings. Better carrying capacity and more effective labyrinth seal makes it more long-lasting.
  • 6. The newly–adopted tooth-boards have greatly increased the useful length of the jaw plate, which increases the capacity.

  JC Jaw Crusher Working Principle

  Crusher chamber adopts "V" structure which could make the actual feed width complies with the nominal one. Adjustment of the discharge part is more convenient. Discharge part of JC series jaw crusher is installed wedge block, which makes discharge more simple, safer and faster than the spacer on old style crusher.
