Do You Know We Should We Change the Parts of Jaw Crusher

Fixed jaw crusher liner ( tooth plate ) , movable jaw liner ( tooth plate ) , both sides of the liner ( guard ) is the easiest to wear . After the severe wear the product particle size larger. Initial wear , you can turn around and use the tooth plate , or turn around and use the up and down two . Jaw plate wear , mostly in the lower part , when the high wears away tooth 3 /5 , that requires root replacement of the liner. When both sides of the liner wear out 2 /5 , also need to replace the new one.

If you rarely wear shaft , just to fix its geometry , can be turned on a lathe , the journal achieve the correct geometry , then the corresponding reduced bearing diameter . But after several such treatment , if the journal size is reduced by 5% when compared to the original , it does not allow re turning up, but should be replaced with new shafts .Jaw crusher is working under impact loading , babbitt lined bearing on the duration of work for about 2 years or so , over the period , you will need to re- cast .

If the eccentric shaft and bearing, spindle and bearing is worn , its tip clearance gap is greater than 1.5 times the original assembly , and needs adjustment or replacement pads ; oil groove wear 1.5mm, should be re-opened oil groove or adjustment. Connecting rod head clearance between the cover and the eccentric shaft , worn to the assembly when the gap is greater than 1.5 times , also need to add a new pad adjustment or replacement .When babbitt bearing on a deeper peel or large abrasions , should be re- cast . For bearing quality processed the following requirements: color babbitt surface should be uniform, dull , silvery white ; babbitt surface layer should not have ash, cracks, blisters , shrinkage and back shell phenomena

At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of portable aggregate crusher, impact stone crusher and free service for assembling various kinds of production line.
