IV. Check the wear of the umbrella panel and each of the pull plates.
V. Check the clearance and the amount of movement of the drive bearing and replace if necessary.
VI. Motor bearing cleaning and refueling. [next]
2) Zhong Xiu
I. The round grinding is completely disassembled, the gear meshing clearance is adjusted, and the upper, middle and lower discs are inspected or replaced.
II. Replace the moving lining and fixing the lining.
III. Replace the tapered sleeve, the machine 2 bushing, the size of the bevel gear, the drive shaft, and so on.
IV. Scrape spherical bearings or replace, weld spherical bearings, etc.
V. Welding repair feed funnel, protective cover, body plate, etc.
VI. Replace the drive shaft assembly or the crush cone assembly.
VII. Replace the oil pump.
3) Overhaul
I. Replace or repair the machine base, handle the spring bolt hole of the machine base, the machine seat ladder, the crack of the machine seat rib, re-cast the foundation, etc.
II. Replace the support ring, adjust the ring part, replace the cone, the main shaft, the eccentric shaft, the bowl-shaped bearing seat, and the size of the bevel gear.
3 , maintenance quality standards
I. The horizontal deviation of the base should be less than 0.1mm per person.
II. The displacement error of the center line of the new and old stands is not more than 2mm.
III. The shaft of the drive shaft should be no more than 0.25-0.3mm.
IV. The matching top clearance of the bearing and shaft of the sliding bearing should be 0.24-0.4mm, the side clearance should be 0.1-0.2mm, and the contact point should be 1-2 points to open the oil groove.
V. The side of the transmission gear gap is 2.5-3mm, and the radial clearance is 3.5-4.3mm.
VI. Gear meshing is normal.
VII. The support ring part is firm and reliable, and the oil hole is unblocked.
VIII. The gap between the eccentric bearing and the bushing is 1.5-2mm, the gap between the vertical shaft and the taper sleeve is 2.5-3mm, and the lower part is 8-10mm. .
IX. The spherical contact width of the spherical bearing and the crushing cone shall be 1/3 - 1/2 of the radius of the spherical bearing, the contact point shall not be less than 1 point per square centimeter, and the wedge gap of 0.5-1 mm shall be maintained along the inner circumference.
X. inlet holes, water holes, an annular sealing groove, the water spray orifices point ore, iron rust, raw sewage and the like must be cleaned, a blowhole may not be arbitrarily expanded or reduced, and the dust seal preventing crushing cone The dust ring gap should be 1.5-3mm.
XI. When installing the moving cone liner, the deflection should not exceed 3mm.
XII. Carry out trial operation, empty running for 15-30 minutes, all parts should have no abnormal vibration and noise, and the support ring should be free from sloshing and jumping. The vibration of the machine base is not more than 0.5mm. .
XIII. After the large and medium repair of the cone crusher , the acceptance procedure must be fulfilled.
Microwave moisture measurement. This technique uses an entirely different method to determine bulk moisture levels. At high frequencies water molecules can be made to rotate or spin. This spin energy level is specific to water due to its size and uniqueness as a triatomic, polar molecule with a single symmetrical rotational dipole.
This specific excitation approach is very similar to those used in Near Infra Red techniques, which make use of the hydrogen-oxygen vibrational energy level where the bond acts as a spring. In water, however, the molecular spin/rotation by microwave technology is very specific and offers an accurate means of measuring water content in solids, powders and granulates which other methods do not provide due to their surface, contact or intrusive nature.
