Notes on Using Cone Crushers
(1) Host working
Ore as possible from the middle of the feed disc, which is to prevent crusher overload, the liner wear is uneven; not directly to the ore into the crusher chamber.
The right to mine is: ore evenly distributed through the distribution plate in the crushing cavity, to roll into the ore can not be higher than the level of acetabular wall.
(2) the largest crusher to the size of ≤ 85% ore to the mine mouth size, otherwise it will lead to lower production crusher, cone crusher damage certain components.
(3) crushers do not load start, so as to avoid accidents.
(4) parking, you must first stop to the mining machine, and into the crushing chamber so that the ore has been broken after discharge, the crusher stop.
(5) crushers work should always check the locking system and the hydraulic pressure of the work, problems are identified in time.
(6) the replacement of rolling acetabular wall
Rolling acetabular wall with screws to adjust the U-shaped ring, between the injection of zinc alloy, so closely, a new installation or replacement of rolling acetabular wall, in working 6-8 hours, you should check their retention, U-shaped and re-tighten the screws.
(7) cone crusher wall replacement
Cone crusher cone wall is fixed to the cone head on the body, zinc alloy casting between the two, new installation or replacement of the new cone crusher working 6-8 hours after the wall, check fastening, and found loose to tight immediately solid.
(8) gear mesh
Circular plate due to friction wear, affecting the clearance of the gear changes, in order to ensure the proper gear meshing must be supplemented in the bottom cover gasket, the gasket should be equal to the thickness of circular plate wear.
(9) bearings and seals
Bowl bearings installed, pay attention not to block oil ring rope break something (with the support of hardwood and other objects between the rope). Assembly, should be scraping the spherical bearing, crushing cone and the bowl to ensure that each sphere in contact with the inner cylindrical 0.35-0.5mm should ensure that the annular gap. Perfusion around the bowl bearing the bar with the nailing of the alloy bearing shelves in the bowl, bowl-shaped bearing along the circumference side to prevent any rotation. Bowl-bearing frame and use the key (sales) and fixed, if the work bowl found in the bearing frame and a gap must be processed immediately.
(10) cylinder sleeve and the transition
With the frame body of a third, in order to prevent the rotating bushing, upper bushing again into a zinc alloy tank, replace bushing should be the actual size of the frame body preparation, After a long period because of broken machines and handling the inevitable result of working with the relationship changes. If the gap is too large will result in bush rupture.
(11) conical bush
Eccentric shaft sleeve with air to strict compliance, injection of zinc alloy sleeve to prevent rotation, zinc alloy to be filled with all the space, due to thermal note the reason may result in zinc alloy sleeve deformation, so the new set of inspection cone size, found no the right to be promptly revised, manufacturing spare parts should be the actual size of the diameter of the eccentric sleeve to keep the original with the preparation.
(12) Spring
The role of the spring when the crusher is not broken into the material to protect the crusher is not damaged, so the spring pressure and crusher crushing force to adapt to the crusher in the spring when the work is not moving, only in the crushing chamber iron into the crusher overload occurs when the lift bearing sleeve spring is compressed phenomenon. The upper cone crusher beating occurred in the normal working hours, this is not a normal phenomenon must be carefully analyzed, the causes and take measures to remove, if the error can not be compressed spring will not only work properly, but the damage to parts may occur, because the compression spring will cause increase in breaking force.
