Cone crusher common problems and methods


The cone crusher at work, should be uniform feeding , not segregation . Feeding inequality appears to reduce production capacity , product size is too large , frequent spring action , the bowl bearing pressure , rising power . Certain amount of time per run , the best equipment with the proper inspection and maintenance , and so will enable the continued production equipment to maintain better operating status , access to better productivity and product quality .
Cone crusher common problems and solutions :
(1) cone crusher is to replace the liner is too time-consuming
Diagnosis: as a broken system, broken equipment , the normal production , liner replacement cycle is generally 30 days , major demolition include : demolition of moving fixed cone lining replacement action , fixed cone lining heated to cone liner , irrigation resin, assembly . Dismantling standard , each replacement takes 4-5 hours , seriously affect the next process normal .
Solution: increase the cone crusher with a heavy guard . Measuring the actual size of the broken machine with a heavy shield cone , lateral 10mm circumference at one with heavy shields , on which the upper stamped cover along above the counterweight guard 10mm, bottom and rib shield welding fixed board. Lateral shield to avoid rib shield plot ore and crushed ore and high-speed rotation of the direct collision of the weight of the shield , the level of cover to avoid the ore into the guard and weight shield to prevent the slag into the weight internal lubrication systems.
(2) cone crusher with a heavy shield is badly worn
Diagnosis: Because the ore viscosity , cone crusher rib nursing board ore accumulation of serious, exacerbated by the weight shield wear and high maintenance costs . Even with the weight shield the outside of the installation of four square steel cleaning block , can not completely solve the problem . Cone crusher speed , the impact of large ore cleaning block only the normal use of three to five days , during welding repair work , due to restricted space , there is a great security risk .
Solution: increase the cone crusher with a heavy guard . Measuring the actual size of the broken machine with a heavy shield cone , lateral 10mm circumference at one with heavy shields , on which the upper stamped cover along above the counterweight guard 10mm, bottom and rib shield welding fixed board. Lateral shield to avoid rib shield plot ore and crushed ore and high-speed rotation of the direct collision of the weight of the shield , the level of cover to avoid the ore into the guard and weight shield to prevent the slag into the weight internal lubrication systems.
(3) cone crusher damage repair heavy workload
Diagnosis : cone crusher, points reel by a greater impact , and could easily lead to the shedding of the mounting bolts cut and sub- feed pan . The life cycle of the shredder liner for 15 days , every time you replace the liner, the need to replace the sub- material plate, cutting ring and mounting bolts , spare parts consumption . Between the liner replacement cycle due to wear , but also the need for cutting ring repair welding and maintenance workload .
Solution: re- default the crusher sub reel . Using steel plates for the skeleton , the sub- topical wear rubber feed pan, rubber elasticity , reduce the impact of the ore on the sub- feed pan to prevent loose in the sub - feed pan . At the same time to ensure wear resistance , adjust the sub- feed pan dimensions, to protect the cutting ring from less affected by wear and tear . this article from www.vkconecrusher.com
