Several common problems of jaw crusher

Jaw crusher is a good crusher currently used. Henan Hongxing Heavy Industry is a relatively professional crusher manufacturer in Henan Province. Today, a common analysis of jaw crusher failures is a simple analysis for everyone.

1. During crusher work, crushing chamber side board liners and crushing tooth plates

Stop the crusher and check that the lining is fixed and hear the metal crash.

Loosen, loose or break the fixing bolts, and use the hammer to strike the fixed wedge crushing tooth plate on the side wall. Then tighten the fixing bolts on the wedge and the lining plate, or replace the fixing bolts on the jaws.

2, thrust plate support (

Insufficient spring tension or spring damage, stop the crusher, adjust the impact of the spring's tension slider) in the thrust plate to support the slider to generate large wear force or replace the spring; replace the support slider; or slack, the thrust plate head wears badly .

Replace the thrust plate.

3, the link head produces collision eccentric bushing wear. Scrape the shaft or replace the new bushing. Hit the sound.

4, broken product granularity broken tooth plate significantly wear.

Turn the crushing tooth plate to 1800; or adjust to increase. Drain the mine, reduce the width dimension.

5. Severe cracking noise falls into non-broken objects, so that the crusher is stopped, the nut is unscrewed, and after the removal, the vibrations are stopped.

The thrust plate is broken or the rivet is cut off; the connecting rod spring will hang forward and the flywheel will continue to rotate. Even the following parts will cause the lower part of the connecting rod to break through and check the thrust plate support and slide. The replacement thrust rod swings back and forth.

Bad; the push rod is installed at the bottom of the connecting rod; the breaker is stopped and the connecting rod is repaired. The spring is slack. Cracks in the groove of the force plate support slider; installation of a safety thrust plate without proper calculation.

6, fastening bolts loose, vibration.

Tighten all bolts completely, especially when the tension bolts of the rack are loose, stop the bolts to loosen. Stop the crusher, put the bolt in mineral oil and preheat it before installing 1500C.

7, flywheel rotation, broken

The spring of the tie rod is damaged; the tie rod loss stops the crusher, the crusher inside the crushing cavity stops working, and the push is broken; the tie bar nut is tripped. Ore, check the cause of the damage, replace the damage plate from the support slider

Bad parts, install the thrust plate.

8. The flywheel significantly loosens the keys of the pulley and the flywheel or stops the crusher. The key is replaced and the movement is corrected. The eccentric shaft is gradually damaged. keyway.

9, the lower part of the crusher

The elasticity of the tie rod buffer spring disappears to replace the spring. The impact is now sounding.
