How to safely use cone crusher and parts replacement method - bearing knowledge

( 1) Cone crusher ore must be assigned in the middle of the plate at work, in order to prevent the breaker overload, make the liner wear inequality; Don't allow the ore into the crushing chamber directly. Ore condition is: the right to mine the distribution plate of uniform dispersion in the crushing cavity, into the ore can not higher than the level of the rolling mortar wall. ( 2) The biggest feeder size crusher 85% or less feed size, otherwise will lead to the crusher production is reduced, cone crusher in some parts of damage. ( 3) Do not load starting crusher, lest cause an accident. ( 4) Parking, have to stop the feeder, and has entered the ore crushing of crushing cavity after discharge, make the crusher parking. ( 5) Crusher work to check the pressure of the locking system and the performance of the hydraulic station, found the problem after timely treatment. ( 6) Rolling mortar wall replacement rolling mortar wall have U the screw on the adjusting ring, between injection of zinc alloy, closely integrated, new installation or replacement of the rolling mortar wall, after six to eight hours at work, should check the fastening situation, and tighten the u-shaped bolt again. ( 7) Cone crushing wall replacement cone crushing wall with a conical head is on the cone body, between the two have zinc alloy casting, new installation or replacement of cone crushing wall work after six to eight hours, check the fastening, find loose fastening immediately. ( 8) Gear mesh as circular plate as a result of the friction wear and affected the change of gear clearance, in order to guarantee the normal of the gear meshing must supplement on the bottom cover gaskets, the gasket thickness shall be equal to the amount of wear and tear of the circular plate. ( 9) Bearing and seal installation bowl bearing, pay attention to not make the wire rope touch bad oil baffle ring ( With the support hardwood such as content between the steel wire rope) 。 Assembly, bearing spherical should undertake research, ensure broken cone with bowl spherical outer circle contact with inner ring should ensure that 0. 35-0. 5 mm of the annular gap. Bowl bearing shell is filled with the surrounding the locking fixed in the bowl of the alloy bearing on the shelf, prevent bowl bearing party any rotation along the circumference. Bowl bearing frame and the frame body with key ( Pin) Found in place, if the work bowl bearing frame and the frame body have a gap must be processed immediately. ( 10) Cylinder liner and the frame body for a third transition fit, in order to prevent the rotation of the bushing, and injected with zinc alloy in slot on the upper bushing, replacing new bushing should be according to the actual size of the frame body configuration, because of the crusher after long work and loading and unloading must cooperate with the change of the relationship. If the clearance is too general cause bushing fracture. ( 11) Conical bushing taper sleeve and empty, and the eccentric shaft to yan turn into zinc alloy in order to prevent the taper sleeve, all clearance shall be filled with the zinc alloy, because of the hot zinc alloy injection may cause deformation of the taper sleeve, so the new cone suit check size, found not correct should be corrected in time, make spare parts should be according to actual size in the diameter of an eccentric sleeve to keep the original. ( 12) Spring spring is used when the crusher entered should not broken things to protect crusher is damaged, so the pressure of the spring and suitable to the crushing force crusher, crusher in normal work when spring is not moving, just fall into iron overloading crusher in the crushing cavity to lift the bearing sets of occurred the phenomenon of the spring is compressed. Beating the upper cone crusher in the normal work, this is not normal phenomenon must be carefully analyzed, the reason, take measures to eliminate, if wrongly compression spring not only can't normal work, instead of parts damage can occur, because the compression spring will cause the increase of the crushing force. Cause upper crusher to beat A number of reasons: A, uneven feed or feed too much B, feed contains too many small pieces, and powdered ore or humidity C, row ore mouth gap is too small. ( 13) Exposed rotating part of the machine, should add a shield.
