It features simple structure, easy maintenance, stable performance, even final particles and high crushing ratio. Our design and production are of high position both at home and abroad.

• Jaw crusher application

    Jaw Crusher is mainly used to crush kinds of mining stones primarily, and the largest compression resistance of the material is 320MPa. The jaw crusher is widely used in stone mining, metallurgy industry, building material, highway, railway, water conservancy and chemical industry.

• Jaw crusher main features and benefits

  • 1. Simple structure and easy maintenance.
  • 2. Stable performance and low operating cost.
  • 3. High crushing ratio.
  • 4. Use high manganese steel, one-off foundry.
  • 5. High resistance to friction, abrasion and compression with longer operating life span.
  • 6. Even final size.

• Jaw crusher main parts

    Jaw Crusher is made up of frame, flywheel, movable plate, fixed plate, toggle plate, set adjustment, main bearing etc. The toggle plate is used for protection, and tension rod used to adjust the size of discharging open to meet different jaw crusher need.
  We also offer spare parts and original wear parts related to the jaw crusher.

• Jaw crusher installation instructions

  • 1. Jaw crusher is installed by the factory, the user should be checked after the receipt of the jaw crusher machine and eliminate the various problems arising from transport, and then install it.
  • 2. Rack installation, the vertical plane at the end of the level of tolerance of 0.5mm / m, the horizontal level degrees (measured on the spindle) Tolerance of 0.15 mm / m.
  • 3. Comprehensive inspection before starting the jaw crusher machine. The fastening of the fixed parts, each part of the ubrication as well as V-belt tension level is to check the suitability of the like should be the focus.
  • 4. Check the overall circuit after cuting off jaw crusher switch, and a clear sign hanging switch.

• Operation and maintenance of jaw crusher

  1. The jaw crusher should be greased and oiled regularly; this should be done prior to each use. To do this, simply turn all grease caps one full turn (clockwise) and put a few squirts of oil in both of the oil cups. If grease caps are tight, add more grease (see MAINTENENCE below).
  2. Check jaws for cleanliness and clean them if needed.
    3. Adjustment of jaw spacing: Turn the circuit breaker (located in the breaker box) to the "ON" position. While the crusher is empty, start the machine and allow it to come up to full speed. The machine must be adjusted while running. Loosen the square-head bolt (left). This will allow the hand knob (or right) to turn. Slowly turn the hand-knob clockwise until the jaws of the crusher can be heard just touching each other, and then back off the hand knob (turn counter-clockwise) just slightly. Slowly begin to re-tighten the square-head locking bolt. As this is done, the clearance of the jaws will decrease and may become too close. If this happens back the hand knob off slightly. Repeat this process until the bolt can be tightened completely without significant tapping of the jaws. It may take some practice to do this properly. This procedure will set the machine to grind as fine as possible (approximately 3 to 5 mm particle size) without damage to the jaws. If larger particles are acceptable, jaw clearance may be set to more than the minimum distance.
  4. Once the jaws have been set, place a clean sample collection tray under the machine to collect the crushed sample. If concerned about contamination of sample material by skin oils and/or perspiration, wear clean, powder free latex (or equivalent) gloves while handling the samples. When sample volumes permit, it is recommended that the machine be "pre-contaminated". This is done by processing a small amount of the sample to be crushed (thus coating the inner workings of the machine) and discarding the resultant product. This reduces the amount of sample contamination from the machine.
  The lower opening of the hopper is 2 3/8" x 4". This limits the size of material that may be crushed. If a sample is to big to fit easily through the opening, then it is too big for the machine to process and must be reduced by other means to an acceptable size. Once a sample passes through the lower hopper opening, it will be quickly crushed and the product will be forced out through the bottom of the machine into the sample collection tray.
  Overheating: If for some reason the machine jams or stops running in the middle of processing, turn the circuit breaker for the machine "OFF" before doing any inspection. Once the circuit breaker is off, the thermal relay and motor relay will need to be reset. Press the red stop button for the machine and reset the relay for the motor (it is located on the motor). Wait a few minutes for the motor to cool. Before turning the breaker switch "ON" and restarting the machine, make sure the cause of the stoppage has been alleviated. NEVER work on the machine while the breaker switch is in the "ON" position.
  5. When the crushing process is complete, remove the sample collection tray and transfer its contents to a clean container.
  6. Prior to next use, clean the crusher and collection tray(s) as described previously. When done for the day, make sure the lab is cleaner than it was when you started, that the breaker to the crusher is turned off, lights are out, and door closed and locked.
