Jaw Crusher operation and maintenance

A Jaw Crusher is a machine used for crushing rocks and minerals, which is widely used in various industries such as mining, road and railway construction and building construction industry. It is mainly composed of a fixed jaw plate and a movable jaw plate that work together to crush the material. Proper operation and maintenance of the jaw crusher can ensure its efficient and long-term use.

Here are some tips on how to operate and maintain a Jaw Crusher:

  1. Operating the Jaw Crusher
  • Start the machine only when it is empty and ensure that all components are in good condition.
  • Check the oil level of the lubrication system regularly and add oil if necessary.
  • Adjust the discharge opening of the jaw crusher according to the size of the material being crushed. A smaller opening is required for finer materials.
  • Feed the material evenly and avoid overloading the machine. A high feeding rate may cause the machine to choke and damage the jaw plates.
  • Stop the machine immediately if there is any abnormal sound or vibration and investigate the cause.
  • Always wear proper protective gear, such as safety glasses and gloves, when operating the machine.
  1. Maintaining the Jaw Crusher
  • Regularly check the wear of the jaw plates and replace them when necessary. The wear of the jaw plates can cause a decrease in the crushing capacity and an increase in the energy consumption.
  • Check the tension of the belts regularly and adjust them if necessary.
  • Clean the machine after each use to prevent the accumulation of dust and debris. Use a brush or compressed air to remove the dust from the machine and its components.
  • Lubricate the machine regularly to ensure smooth operation. Follow the manufacturer’s instructions for the type and amount of lubricant to use.
  • Check the condition of the bearings and replace them if necessary. Faulty bearings can cause excessive vibration and noise.
  • Inspect the electrical system regularly and replace any damaged or worn-out components.
  • Have the machine inspected by a qualified technician at least once a year to ensure its optimal performance and safety.

A Jaw Crusher is a powerful and valuable machine for crushing rocks and minerals. Proper operation and maintenance can ensure its efficient and long-term use. Always follow the manufacturer’s instructions for operating and maintaining the machine, and regularly inspect and replace any worn or damaged components.
