Jaw Crusher Maintenance Records
- the host suddenly stop (commonly known as: boring car).
Reasons: 1, the discharge port blockage, resulting wholehearted blocking material; 2, the rotation of the drive sheave V-belt is too loose, causing the belt to slip; 3, the eccentric shaft adapter sleeve loose, causing the bearing housing on both sides of the rack without gaps , the eccentric shaft stuck, unable to rotate; 4, workplaces voltage is too low, the host aniseed after the encounter, unable broken; 5, the bearing damage.
Remedy: 1, remove the discharge port plugs to ensure the smooth flow of the material;2, tighten or replace V-belt; 3, re-install or replace the adapter sleeve; 4, align the workplace voltage, to conform to the host operating voltage requirements; 5, replace the bearing.
- the host sheaves, moving jaw functioning normally, but broken cease work.
Reasons: 1, tension spring break; 2, rod fracture; 3, brackets off or broken.
Remedy: 1. Replace the tension spring; 2, replace the rod; 3, re-install or replace the bracket.
- the production was less than the factory standard.
Reasons: 1, hardness or toughness material to be broken over the use of the range specified in the instructions; 2, motor wiring position is reversed, the host opened the anti-car (moving jaw clockwise rotation), or motor connected in delta connection star connection; 3, the nesting population is less than a predetermined limit; 4, jaw displacement, with the addendum addendum relative; 5, work site voltage is too low; 6, after moving jaw and bearing wear gap is too large, the bearing outer ring relative rotation .
Remedy: 1, replace or increase crusher; 2, exchange electrical wiring; 3, nesting population adjustment to the instructions provided for a nominal increase in the discharge port and a crusher for crushing; 4. Check tooth plate pitch dimensions, such as shall replace sub-standard jaw plates, adjusting the relative position of being fixed jaw plate and movable jaw, and ensure the addendum to the tooth root, the fixed clamping to prevent displacement; 5, to increase the voltage of the workplace to adapt Host weight load requirements; 6, replacement of bearings or moving the jaw.
- the activities and the fixed jaw plate beating or crash at work.
Reasons: 1, the jaw of fastening bolts loose or falling; 2, nesting population is too small, the two jaw plates collide with each other at the bottom.
Remedy: 1, complete with an adapter or bolt; 2, align the nesting population to ensure the correct gap between the two jaws.
