Jaw crushers are usually used for the primary crushing stage in production lines, and their output directly affects the capacity of the entire production line. Meanwhile, we can reduce equipment idle by increasing output per unit time, thus reducing energy consumption and labor costs, finally improving the overall efficiency. Today, we are glad to share with you a few tips for increasing capacity for Jaw crusher.

1. Optimize the feed size, STUCK NO MORE!

• Material selection: 

  Choose dry and low mud materials to reduce adhesion and clogging in the crushing process and improve crushing efficiency.

• Feed size:

  Control the feed size less than 85% short side of the crusher inlet size, or oversize material will easy to be stuck at the opening of jaw crusher.

2. Control the feed rate, avoid overfeed clogging

• Constant right feeding rate:Jaw crushers are intermittent working equipment. Underfeed or overfeed both affect the final capacity. Underfeed results in a light load. Overfeed leads to Material accumulation, can’t be crushed in time.

      Therefore, we should strictly control the feeding rate,at the same time, keep a constant feeding rate by adjusting the amplitude of the feeder  (within the feeder amplitude range) according to the output demand of the production line. Normally, when the feeding rate is up to 2/3 of the crushing chamber,the efficiency is the highest.

      Meanwhile,we should also avoid the material directly impact the moving jaw when feeding,and prevent the head of the moving jaw when  feeding, and prevent the head of the moving jaw to be damaged. Additionally, adjusting feed angle ensure feeding smooth.

3. Adjust equipment properly, improve processing capacity

• Adjustment of CSS and the angle between the movable jaw plate and the fixed jaw:Due to CSS of jaw crusher determines the production capacity,we should make appropriate adjustments for CSS according to the demand size for two-stage crushing. The angle (between the moving jaw plate and the fixed jaw plate) is generally within the range of 17-26 °. Appropriately increasing the CSS size, reducing the angle and crushing rate can improve production efficiency.
• Adjustment of eccentric shaft speed: 

  Increasing the eccentric shaft speed appropriately is good for improving material crushing efficiency. But it should be noted that excessive speed may make materials not be discharged in time, causing material blockage and reducing production capacity.

  

4. Regular maintenance equipment

• Jaw plate adjustment and replacement:Regularly maintain and inspect the equipment to ensure that it is in good condition. Regularly check the wear status of the jaw plate and take some measures according to the wear situation, such as turning around, exchanging or replacing the jaw plate, which helps to maintain the crushing efficiency of the crusher.
• Lubrication and maintenance:

  High quality lubrication is the key to ensure the performance and service life of bearings. In daily equipment operation, the bearings of jaw crushers should be regularly lubricated and maintained to ensure their normal operation.

Take care of your  jaw crushers anytime, anywhere. For more information, you can also contact your local dealer or Borgers service team.
