First, idle test
After the above parts are installed, an empty load test shall be performed to check if the installation meets the requirements. If it is found to be improper, it is easy to repair at this time.
1. Check the fastening of the main joint before starting the crusher.
2. Before starting, use hands to move the drive section, at least make the eccentric shaft turn 2-3 circles, and think that it can be driven when there is no neck phenomenon.
3. Before starting the crusher, the oil pump should be started. Know that each lubrication point is lubricated. See the oil back box before starting the crusher.
4, idle test continuous operation not less than 2 hours.
5, crusher idling test must meet the following requirements:
1. The number of revolutions of the broken cone around its own centerline must not exceed 15 rpm.
2. Bevel gears must not have periodic noise.
3, lubrication device should meet the following requirements:
I. The pressure of the feed pipe should be in the range of 0.08 to 0.15 MPa.
II, the return temperature does not exceed 50 °C.
4. After dismantling the test, copper burns and wear should not occur in the friction parts of the cone crusher.
6. If the number of broken cone revolutions may soon produce undesirable phenomena, it should be immediately stopped, checked and corrected, and at the same time check the amount of oil to be supplied, and then test again.
7. If the conical gear has periodic noise, check the correctness of the gear installation and check the gear clearance.
Second, the load test:
1. After the idling test is passed, the load test can be conducted.
2. The load test shall be carried out continuously for two days and nights (allowing short-term parking inspections).
3. Add a small amount of ore at the beginning of the load test and gradually increase to full load.
4. The load test must meet the following requirements:
1. The crusher has no sharp vibration and noise.
2, crusher to mine, ore discharge normal and the provisions of the output.
3, the lubrication system load to the following:
I. The oil pressure is in the range of 0.08 to 0.15 MPa.
II, return oil temperature does not exceed 60 °C.
4, the wear parts have no damage.
5, electrical equipment is working properly.
Third, the adjustment of the outlet
The crusher discharge port depends on the desired product size. In most cases, the adjustment sleeve is adjusted so that the opening between the crushing linings at the closed edge is slightly smaller than the particle size of the desired product, and the adjustment sleeve can be adjusted when the product size is changed. Adjustment sleeves can also be adjusted to compensate for the wear of the crushing wall and rolling wall.
The initial discharge port determined according to the desired product size is not necessarily the best discharge port for maximum production. This row ore generally depends on the characteristics of the broken material, the power consumption of the crusher motor or engine, or the working conditions of the support sleeve.
The crusher’s discharge port changes with the adjustment sleeve moving up and down in the support sleeve. The adjustment sleeve descends when rotated clockwise, and the adjustment sleeve rises when it rotates counterclockwise. When the adjustment sleeve descends, the ore discharge decreases, and when the adjustment sleeve rises, the discharge opening increases.
Fourth, determine the liner wear
For accurate wear records, the wear of the liner can be known without stopping. For the first liner, the following requirements should be recorded:
1. After setting the crusher’s discharge port, swing the locking screw inwards so that it rests on the flange of the adjusting cap and turn the adjusting cap slightly in a certain direction so that the hole on the locking screw and the flange of the adjusting cap The holes are aligned and the locking screw is fixed to the adjusting cap flange with a nut and a disc spring.
2. Make a mark on the position of a positioning pin of the adjustment cap to indicate the initial locking position. The hole in the adjusting cap flange is turned to the next hole in the locking screw and the adjusting sleeve is then brought into a new locking position, which is also adjusted in the vertical direction.
3. During the normal operation, the accurate number of the locking position should be accurately recorded when using the first liner. Record the locking position until the liner is scrapped.
Since there will be no two identical crushing operations, the types, thicknesses and casting tolerances of the liners used will be very large, so it is not possible to predict in advance how many locking positions a set of liners can pass before being scrapped.
4. After the liner wears out and is determined to be scrapped, adjust the position of the cap seal ring by drawing a horizontal short line on the adjustment funnel before turning the adjusting sleeve to remove the liner.
5. After installing the new liner, it is also necessary to make a comparison of the locked position records to determine the degree of wear of the liner. Each time the adjustment is performed (decrease), the adjustment funnel is moved downward once. When the liner is close to the wear limit, the mark drawn on the adjusting sleeve funnel will be displayed. Since the wear of any two sets of liners will not be the same, after a few sets of liners, a fairly accurate average position can be determined.
