• JC series jaw crusher application

  This series of jaw crushers have wide range of application and is mainly used to crush mid hardness ores and rocks in metallurgical industry, mining, chemistry, cement making industry, construction, refractory, pottery and porcelain making for secondary and fine crushing. It is preferred to crush hard rock, such as basalt, river pebbles, ores, rocks, slogs, etc, whose compressive strength is under 280Mpa. Maximum size of feed materials must be less than what is required according to the specifications.

• JC series jaw crusher main features and benefits

  • 1. World-level manufacturing technology is adopted, perfect raw material is selected.
  • 2. More advanced movable jaw assembly lengthens life of JC jaw crushers.
    Movable jaw assembly, composed of cast steel structure with high-quality, is driven by two big flying wheels which are also made from cast steel. Moreover, heavy eccentric axle is processed by forged mold. All of these make the JCE series crusher extremely reliable.
  • 3. Integral cast steel bearing housings.
    Integral cast steel bearing matches well with the crusher frame, at the same time, radial strength of the bearing seat is highly strengthened. However, the separate bearing seat does not have this advantage.
  • 4. Finite element analysis technology is adopted to make the crusher more stronger.
  • 5. Crusher chamber adopts "V" structure which could make actual feed width comply with the nominal one.
  • 6. Adjustment of the discharge part is more convenient.
    Discharge part of JCE series crusher is installed wedge block, which makes discharge much simpler, safer and faster than the spacer on old style crusher.
  • 7. Bearing with larger specification and stronger capacity are used.
  • 8. A newly designed tooth-shape jaw plate, makes the available area of jaw plate longer, and enhances the capacity.

• JC series jaw crusher main parts

  The JC series of jaw crushers in European style are mainly consist of frame, the rotation part of the eccentric bearing, the working part of the crushing cavity, the safety unit and the adjustment devices of the discharging opening.
  We also offer spare parts and original wear parts related to the jc jaw crusher.

• Operation and maintenance of JC series jaw crusher

  For all the machinery, the maintenance is very important. In the stone crusher equipment, jaw crusher is dominant, and in maintenance pay attention to the way. To ensure the jaw crusher regular work, in addition to proper operation, planned maintenance is need, including routine maintenance inspection, overhaul, repair, and minor repairs .
  (1) Overhaul: In addition to all the ongoing repair work, including replacing eccentric shaft and the moving jaw mandrels, casting rod head the Department of Babbitt, replacement or repair of wear and tear. Overhaul cycle is generally five years.
  (2) repair: In addition to minor repairs of all the work, but also include the replacement of thrust plates, linings, inspection and repair bearings and so on. In the repair cycle is generally 1-2 years.
  (3) minor repairs: The main elements include checking and repair adjustment device, high-speed gap nesting population on the wear liner U-turn or replaced. Transmission part of the overhaul, lubrication system and replacement of oil and so on. Minor repairs of the period is 1-3 months.

Jaw crusher for sale

• Jaw crusher overview

  Jaw crusher is one of the most widely used crushing equipment in mining industry. It is ideally suitable for primary and secondary crushing. 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

• 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.
