15 cone crusher work matters needing attention:
( 1) the ore must be at the distribution plate in the middle, as shown in Figure 14, are not allowed to be directly into. Because it is easy to make the crusher overload, making the lining uneven wear.
The right to mine conditions:
A ore distribution plate is evenly dispersed in the crushing cavity.
B to the ore above the rolling mortar wall level ( as shown in Figure 15. )
( 2) the largest crusher ore size, not equal to mine mouth size, ( to block size≤ 85% feed port size ) would otherwise lead to:
A crusher yield reduction.
B crusher some other pieces of damage.
( 3) crusher no load, load will cause accident.
( 4) when parking, you must first stop the feeder, and made into the crushing chamber of ore crushing after discharge, the crusher parking.
( 5) the crusher work should always check the locking system pressure and hydraulic station work, found problems in a timely manner.
The 16 crushing machine production
Crusher output, and the feeding mode, feeding block, row block size, physical and mechanical properties of the ore, temperature and so on, a wide range of manufacturing plant, yield is given at the specified conditions to approximate the throughput.
17 rolling mortar wall replacement
The rolling mortar wall of U shaped screw in adjusting ring, between injection of zinc alloy, which closely, new installation or replacement of the rolling mortar wall, in 6 – 8 hours, should be examined for fastening, again and tighten U screw.
18 conical crushing wall replacement
cone head is fixed on the wall is a cone body, between the two casting zinc alloy, a new installation or replacement of cone crusher wall working 6-8 hours, should be examined for fastening, loose shall immediately fastening.
The round plate wear due to friction, impact of the gear gap changes, in order to ensure the normal meshing gear must be on the bottom cover gasket gasket is added, the thickness should be equal to the amount of wear plate.
20 bearing and sealing device
Installation of bearing, careful not to make the steel wire rope broken oil retaining ring ( available in hardwood support between the wire rope ).
When assembling, bearing spherical should be scraping, ensure the cone crusher and the bowl-shaped cross spherical outer circular contact ring should ensure that the 0.35 0.5mm annular clearance.
The bowl-shaped bushing is used around the perfusion of the Ba alloy lock pin fixed on the bearing frame, prevent the bowl-shaped bushing along the circumferential side where rotation.
Bearing frame and the frame body by keys ( PIN ) is fixed, if found in the bearing frame and the frame body has a gap must be deal with immediately.
The 21 cylindrical bushing and a frame body for the third kinds of transition fit, in order to prevent rotation of the bushing, and the bushing upper slot injection of zinc alloy, replacement of bushings should be based on the frame of the actual size of the preparation, because the crusher after long time working and handling will inevitably lead to cooperation relations change. If the gap is too big to Bush rupture.
22 conical bushing
Taper sleeve and the eccentric hollow shaft to lapping, injection of zinc alloy in order to prevent the cone sleeve to rotate, zinc alloy to fill all space, because the heat injection zinc alloy reasons may cause sleeve distortion, so the new cone set check size D1, D2 and B should be timely correction of incorrect, should be based on the manufacturing spare parts eccentric sleeve inside the actual size of the preparation to maintain the original mix.
The 23 spring
( 1) the action of the spring when the crusher is entered can not be broken when the protection of crusher is not damaged, so the pressure of the spring and the crushing force to adapt, crushing machine in normal operation spring is not moving, only in the crushing cavity into the crusher to iron overload lifting support set to occur by a compression spring phenomenon.
( 2) the upper portion of the crusher in normal jumping during working, this is not a normal phenomenon must be carefully analyzed, reason, take measures to eliminate the error, if the compression spring can not work normally, but the possible damage of components, because the compression spring will cause breaking force increases.
Resulting in the upper portion of the crusher beating for several reasons:
A feed or uneven feeding too much
B to mine contained too many pieces and powder ore or humidity is too big.
C discharging gap is too small.
