Easily-damaged parts of Impact crusher mainly include: plate hammer, liner
and bearing.
When we replace the easily-damaged parts, we should do as
follow. First, open shelves and unload the screw connecting upper shelf and
middle box, next, use wrench to flip hex head part, and slowly open shelves. At
the same time, we can hang the after-frame by cable suspension device, and then
repeat the above process until shelves close.
1. Replacement of impact
crusher plate hammer: plate hammer should be timely adjusted or replaced when
they are worn to a certain extent to avoid the injury of the fasteners and other
components.
2. Replacement of impact crusher liner: first, open the cover,
remove the cotter pin, slotted nuts and bolts which are used to fix liner, and
then replace the liner. If install a new liner, just to upside down the
steps.
3. Treatment of impact crusher bearing: the reason why bearing is of
over-high temperature are that: (1) excess or deficiency lubricating grease.
Then we just try to check whether lubricating grease is excess; (2) smudgy
lubricating grease. Then we just try to clean and replace grease;（3）damaged
bearing. Then we just try to replace a new bearing.
Impact crusher plays a
crucial role in sand making production line, we should timely maintain and
repair it in the use of the process, try to eliminate problems in the bud to
avoid more severe loss, in this way, ensure sand-making production line keeps in
a normal and steady state.
Ways to the reduction of hammer crusher head
wearing: select a reasonable speed. Quickly improve hammer head’s impacting and
hardening degree in early process; improve grate bar structure to make the
material-excluding expedite; often adjust the gap between parts, so that it is
in a proper range. These ways would help reduce hammer wearing. From analyzing
factors that influence hammer crusher head, we should adopt different measures
to reduce wearing, prolong the service life, reduce material consumption and
downtime, reduce costs and improve the economic efficiency of enterprises.
At
present, our country mainly adopts high manganese steel flat hammer and impact
plate. Because different manufacturer adopt different heat treatment and
material, the life expectancies are also equally intervallic. Our country also
researched use dilute alloy white cast iron or of high chromium iron manufacture
impact hammer for its high hardness, good wearing-resistance, convenient
production, low cost, which achieved good results. There are a number of
manufacturers adopt surfacing welding layer method by welding" - 64" or " - 64A"
electrode or high fierce steel electrode it can not only improve the
wear-resistance and service life, but also repair old plate hammer or impact
plate. Plate hammer shape and fixing method are very important in repairing
process, besides convenient dismounting, plate hammer shape also should improve
the utilization rate of the metal. Plate hammer quality should be accurate for
whose error should be limited within 0.5kg, in order to ensure the smooth
running of the machine rotates. In addition, the rotor cannot rotate 1 / 10 of
the circumference at any state in rotor static balance experiment.
With its high quality products such as , , , , , Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
